How to Make Buttermilk Substitute (Bold Baking Basics)
Save RecipeHi Bold Bakers!
Working as a professional chef I have learned a lot over the years and I’m excited to share what I’ve learned with you.
How to Make Buttermilk at home is a very important Bold Baking Basic I think you need to know. I use Buttermilk a lot in my baking, however not on a weekly basis. I find myself using half a carton in a recipe and then by the time I want to use it again it is bad I would have to throw it away. I hate waste so my simple solution to eliminate waste is to make the amount that I need using just milk and lemon juice.
Buttermilk is an important ingredient in baking. It adds flavor and makes moist, rich cakes. I love using it to bake. Once you know how simple it is to make you never have to leave it out of your recipes again.
This Homemade Buttermilk makes a great addition to any pancake recipe, like my Best-Ever Buttermilk Pancake recipe, Red Velvet Pancakes and even my Churro Waffles. Plus, I use it in my Best-Ever Chocolate Cake and traditional Irish Soda Bread.
Buttermilk is widely available in Ireland as it is a main ingredient in traditional Brown Soda Bread. However since moving to the U.S I realized it’s not as readily available. If you are in this situation you now know that you can whip up a great substitution is minutes.

- 2 tablespoons freshly squeezed lemon juice or white vinegar
- 1 Cup (8oz / 224g) milk (full or low fat)
-
Measure the milk into a jug
-
Stir in lemon juice or vinegar into the milk. Stir to combine. Let sit for 30 minutes at room temperature until the milk begins to curdle and becomes acidic.
-
Use in place of buttermilk in the recipe as it calls for. And if you don’t use it straight away store it in the fridge for up to 3 days.

I don't recommend freezing Buttermilk. Dairy doesn't always defrost the same way.

Hi, love your recipes and videos. I have been making buttermilk at home but I use Apple Cider vinegar as we dont use white vinegar. Would that make a difference?
Also we dont drink coffee at home. so would instant coffee dissolved in hot water work?
Hi there,
Instant coffee is a great help in baking, it works better than the real thing. Dissolve it in the tiny bit of water for best results.
Any vinegar will do this for you, when I say white I am just saying not a dark one, it will look odd!
Gemma 🙂
Hi Gemma Keen to try out your recipe. Can I use dairy-free milk, like soya,almond or coconut milk please?
Hi Carmen,
So the milks you mentioned won’t curdle and that is what you need from buttermilk. However depending on the recipe you can just use that milk instead of buttermilk.
Best,
Gemma.
Hi Gemma
I just found your recipes recently…. just love watching ur all recipes. I wanted to try the muffins recipe. Could u pls tell me if I don’t have fresh lemon can I use lemon juice comes in the bottle….. or what kind of vinegar i need to use white vinegar or apple sider….or can I just use regular milk… pls reply… I was going to try tomorrow
Thank you so much
❤️
Hi Ashu,
you can use any acid ingredient. If you have any white vinegar that will be perfect, and it will be more active than the bottle of lemon juice too, go for the vinegar I say!
I hope you enjoy your muffins,
Gemma 🙂
I found buttermilk in powder form, if I need 1 cup of buttermilk, what is the ration of buttermilk and water, do I even have to dilute it or do I just add the buttermilk powder to the dry ingredients, and again if yes, how many tablespoons or teaspoons to meet the 1 cup required in a recipe?
Hi Maria Louise,
I think it usually tells you on the pack how you should dilute this. It will be best to add it as a wet ingredient, so mix it according to the directions on the pack so that it matches the amount required by your recipe. For powdered milk, in general, the ratio is 1:3. That is 1/3 cup of powdered milk to one cup of water for instance.
I hope this is of help,
Gemma 🙂
Wow!!! You really replied! I’m ecstatic!💚🥰 unfortunately, here in our country since its quite costly, I got a “repacked” one which is transferred into a clear plastic and so packaging does not come with instructions😕 but super duper thanks for the tips, 1:3 it is🙂 thanks for making baking “doable” for us hopefuls🙏🏻 God bless!
Hi Maria,
we will all be getting our food in this sustainable way one day, it is the way it used to be!
Thank you for being here with us,
Gemma 🙂
Hi Gemma always using your recipes, today I’ve made banana loaf, strawberry jam and was going to make buttermilk but I was wondering can I use distilled malt vinegar ? Keep up the good work 😊 my family loves eating the food I bake 😁
Yay!!! I’m thrilled to hear that! yes you can use malt vinegar.
Thanks for trying it out.
Best,
Gemma.
Hi Gemma.
In India, we make buttermilk by churning curd and water. Can it be used in cake batter? Does the ratio of water and curd affect the cake texture?
Thanks is advance
Hi there,
Here is what I know about curd: It is made by boiling and cooling the milk to 30-40°C and adding a spoonful of curd. Curd has lactic acid bacteria or lactobacillus. This bacteria multiplies itself in the ambient temperature of 30-40°C and in few hours ferments the milk to form a curd. Curd is a rich source of calcium and protein and is suitable for lactose intolerant people.
This means that it is an acid ingredient, which in turn means that it will work in a recipe requiring buttermilk. After that it will depend on the recipe. You can certainly try it!
Gemma 🙂
Hi Gemma,
I’ve been following your videos for a while and I’ve tried some of your recipes, and they turned out great. I also discovered I have a lot of passion to baking thanks to you.
I wanna ask if I can use yogurt whey instead of buttermilk and olive oil instead of butter for the Irish bread recipe?
Hi Lama,
Thank you for your kind words.
Yes, the yogurt is perfect for this recipe, use it along with full-fat milk, not entirely on its own. Again you will culture the milk with it, about 3 tablespoons of yogurt to the amount of milk. Traditionally butter or eggs were not always used in this bread. you can add a little oil if you wish, but it is not strictly necessary. Margarine works well too.
What matters is that you work fast with this, do not overdevelop the gluten, then all will be well,
Gemma 🙂
in your recipe for buttermilk you say to use full or low fat milk. Is low fat the same as our semi skimmed or is it skimmed milk
Hi semi skimmed is low fat, yes. Really any will do. I just like higher fat for more richness.
Can I use strong white bread flour instead of all purpose flour for irish and traditional soda bread
Hi, yes you can in that kind of recipe.
Can I use strong white bread flour instead or plain flour.
Plain flour is the same as all purpose flour right?
Hi, plain is the same as AP but i would not suggest you switch it out bread flour.
Whern I make burrermilk for the traditional irish soda do i have to use 2 cups of milk and 4 tbsp of lemon juice as your reipe requires 400ml. i cup milk is 240ml.
Yes, that is what i would suggest for this. Enjoy!
Can you use apple cider vinegar
Hi, i suggest you us lemon juice here.
Hi Gemma,
Do you skim the curdles off the top before using?
Hi, know i just give it a good stir.
I used your recipe for buttermilk to make the Irish White Soda Bread and it worked like magic. Bread was really good, too. Now, I am wondering if I can use the buttermilk recipe to make a Buttermilk Pie. Will using the milk and vinegar recipe for the buttermilk work in the pie?
Hi Peggy,
If you make this pie from buttermilk from the store it is probably a cultured buttermilk, which is a similar thing to my recipe. A natural buttermilk is a different thing, it is the residue remaining after the butter making process, slightly sour. I know this is a traditional Southern US pie, and I have never made it. It is similar to any custard pie which would be made with fresh milk.
So, I am thinking that what I would do for this pie is to culture your milk with a natural organic yogurt. A tablespoon of yogurt per cup of milk will do it, allow to stand for at least one hour at room temperature, and that will do it for you.
I hope this helps, I am putting this together in my head, but this makes sense to me, it wil lbe nicer in your pie than a buttermilk cultured with vinegar!
Gemma 🙂
Because it’s quite warm where I live (South Africa) we tend to use long-life milk, especially in summer. Does this make a difference for all your basic baking recipes (e.g. cheeses, buttermilk) – in fact for all your recipes? What is done to make milk long-life milk? I tried making cream cheese with long-life milk, but I only got minute bits of curd, not clumps of it… was the problem with the milk (perhaps what is considered full cream in SA is not really the full cream milk required for these recipes) or the lemon juice (I used the bottled lemon juice)? I have bough white spirit vinegar (as opposed to white grape vinegar) in order to try again but would prefer not to waste more milk if the problem is with the milk. Thanks.
Hi Wendy,
this is a very good question. Long life milk is Ultra Heat Treated, effectively sterilizing the milk and cream. This process tends to denature the milk, and though you can get it to curdle it is not as easy as it is with fresh milk, which has been pasteurized. The result you got is exactly what you will get with this, though the vinegar will be more effective than bottled lemon juice or fresh lemon juice. The result is more ricotta like, the curds tend to be tiny and they will struggle to stick together if you try to cream them. If you do try again with the vinegar, so as not to waste, just try a little amount of the milk, a few ozs will do it. For things like buttermilk sub it will be perfect, and for all of the baking it works really well.
my ice cream recipe seems to tolerate this cream, once it has a sufficiently high fat content to whip up.
It is a difficulty around the world, in hot countries where dairy would always have been a challenge there are powdered alternatives, and again they have some uses, and can be tried for cream cheese too, quite effectively, this may be another alternative for you.
I hope this is of help,
Gemma 🙂
Can I use semi skimmed milk to make buttermilk substitute?
Hi, i would not suggest that as the fat content is not high enough to whip up.
hi gemma Can I use apple cider vinegar?
Hi, yes that will work but the fresh lemon juice is stronger.
Can I use the buttermilk from making butter from you recipe? With or without the lemon juice? Thanks….love your recipes
Hi Terina,
Yes, this is natural buttermilk, strain it out before you add the iced water, you can drink this one too! All will be well,
Gemma 🙂
Hi Gemma,
I love your all new recipes. I like to try 3 layer microwave but i have a question regarding homemade buttermilk. which is can I use lime instead of lemon to milk?
Hi, yes that will work too.
HI Gemma,
My kids, husband and I are a great fan of you and your baking. You see, all this while, I never had an proper oven to do my baking. 2 years ago a good friend of ours (an Australian expat couple) gave us their microwave oven (considered new as they have only used it a couple of time for heating food) before going back to Australia for good. My hands were so itchy to start some basic baking but I was told that I can’t bake good cakes using microwave. I got a little disappointed but started doing my research. And one magical evening, I stumbled upon your videos. I was walking over the clouds when I discovered your microwave mug cakes and other cake recipes. Immediately I started trying them one by one and I was so happy. However, after some time, I wanted to do real baking. Finally in Jan this year, I bought a proper electric oven. And now I watch your videos for more advance cakes and learn other techniques. Thank you so much Gemma for all your videos and encouragements. You are a GEM.
By the way, regarding the buttermilk video. I have a small question. Won’t the milk turn into yogurt after adding the lemon juice? So is buttermilk equivalent to yogurt? Can I substitute buttermilk with yogurt?
Thank you very much in advance for your reply. Keep baking and rocking.
Love,
vathsala
Hello there Vatsala,
How lovely! Thank you for this story, and a big thanks to your Aussie friends too, they got you going!
Buttermilk sub/cultured buttermilk is not yogurt, and will never be so. see here (https://www.biggerbolderbaking.com/how-to-make-yogurt/).
Reall what you are doing is souring the milk, to bring an acid ingredient to your baking. In that sense you are right, yogurt is also an acid ingredient, and it too can be used where buttermilk is called for. You can mix a little with fresh cream too when sour cream is called for and whip it up.
see too the cream cheese recipe here, that may also be of help to you. I hope you enjoy your new cooker, read the instruction book carefully so that you get the very best from it,
Gemma 🙂
Hi Jemma
Can I ask two questions.
If I brought butter milk from the supermarket, can I freeze it , in ice cube trays. To use as an when recipes need it ?
Can I do the same with whole milk as my family drinks semi skimmed or can I use semi skimmed milk instead of recipes that say whole milk. ?
I look forward to your reply
Thank you.
Hi Charlotte,
The difference between whole milk ans skimmed/semi skimmed milk is of course the fat content, but you know this.
Semi skimmed milk has about 1.5% fat content, full fat milk will ave 3.5% fat content, little enough difference.
You can easily sub one for the other in almost every recipe without any material difference to the result. Do not fret about this, you can make your own sub buttermilk as required, that will be best,
Gemma 🙂
Hi Gemma,
You are such a gem of a baker. I love this whole baking basics series. I am getting to learn so much. And I guess basics are very important for baking. You are doing a great job, keep it up and all best to you.
I love baking, and each time I use to pick recipes for which I had all the ingredients because I didn’t know how to substitute one thing for another and sometimes use to waste a whole lot of time searching for a recipe with the ingredients I had on hand or ended up buying some ingredient especially for a recipe. I have bought buttermilk in past especially for a recipe. But now thanks to you I never have to as milk and lemon are staple in my kitchen all the time.
I have one question here in this buttermilk recipe though, what temperature should the milk be, room temperature or cold will do?
Lots of love to you.
Thanks in advance.
Hi there,
thank you so much for your kind words.
You see I think you are a great bold baker, and already are understanding the science! If you are going to use the milk right away then it will culture quicker if slightly warm, I say blood temperature. A cup of cold milk will come to this temperature in about 30 seconds in the microwave.
I am delighted to have you baking with us, keep up the good work you too!
Gemma 🙂
Its not working 1 cup of milk 1 tablespoon of fresh lemon juice been sitting out for 2 hrs nothing is happening
Hi there, you might need to add more lemon juice, the milk will curdle from the acid as long as there is enough.
Will 2% milk work?
Yes!
Hello
Can I use milk made with powdered milk?
Thank you,
Hi, i would not suggest that for this recipe.
Can I use for Ranch dressing?
For sure!
Gemma, you are so fun to watch and such a great teacher. Thank you for everything.
Hi Tacy,
Thank you. That is very kind. I try to keep it simple, for me as much as you!
Good that you are with us,
Gemma 🙂
Hi Gemma,
Can I use this if I am making a red velvet buttercream?
Yes, you can!
Hi Emma
I normally make paneer(cottage cheese) like this however the milk is boiled when I do so and lemon or vinegar is added once the milk boils. The liquid is called whey or is that buttermilk too?
That’s whey but it can be used as buttermilk because it is dairy and it’s acidic.
Gemma 🙂
Will this work with dairy free milk?
No, i suggest you use dairy milk otherwise it might not curdle.
Hi Gemma,
I just have mayonnaise will this work instead of milk?
All the best,
Donald
Hi Donald,
Interesting question! it is certainly used in place of eggs in some recipes, and why not?
It has that little acid, which is what you are looking for here, so it may indeed work for you, depending on the recipe. I am not 100% sure, but it is worth a shot,
Gemma 🙂
can i use whipping cream?
Hi yes you can. Enjoy!
Can u use pick milk?
Yes, you can! Enjoy!
Can i use canned evarporated milk
I would not suggest that, as it will be too sweet to have the same flavor.
Can I use regular store bought whole milk or does it have to be fresh milk?
Hi Missy! Regular store bought milk will work just fine. I hope you enjoy!
