Ingredients
- Brownie Recipe
- 1 ¾ cups (9oz/265g) all-purpose flour
- 1 ½ teaspoon salt
- 3 tablespoons dark unsweetened cocoa powder
- 16 ½ oz (465g) dark chocolate, coarsely chopped
- 1 ½ cup (12oz/337g) unsalted butter
- 2 ¼ cups (18oz/ 510g) granulated sugar
- ¾ cups (6oz/168g) packed light brown sugar
- 7 eggs at room temperature
- 3 tsp vanilla extract
- Cookie Dough Frosting Recipe
- 1 cup (8 oz/225g) cream cheese, softened
- 10 Tbsp (5oz/150g) butter, softened
- 1 ⅓ cup brown sugar
- 2 tsp. vanilla
- 4 Tbsp. milk , more if needed to reach desired consistency
- 1 cup flour
- 6 cups powdered sugar , more if needed to reach desired consistency
- 1 ⅓ cup mini chocolate chips
- Ganache
- 8 oz/225g bittersweet chocolate ( 72 %)
- 1 cup heavy cream
Instructions
- To make the Brownies: Preheat the oven to 350oF (180oC). Butter and line a 9” springform or cake tin.
- Put the chocolate and butter in a large bowl and set it over a saucepan of simmering water or place in the microwave. Stirring occasionally, until the chocolate and butter are completely melted and smooth. Remove from the heat and set aside to cool a little.
- Add the sugars. Whisk until completely combined. The mixture should be room temperature.
- Whisk the eggs and vanilla in a jug together. Add a little of the eggs to the chocolate mixture and whisk until combined. Add the remaining eggs and whisk until combined. Do not overbeat the batter at this stage or your brownies will be cakey.
- Sift the flour, salt and cocoa over the chocolate mixture. Using a rubber spatula (not a whisk), fold the flour mixture into the chocolate until just a bit of the flour mixture is visible.
- Pour the batter into your lined and buttered. Bake in the center of the oven on a tray for 1 hour 20 minutes. This is a very heavy brownie and does need quite some time to cook.
- There should be still a jiggle in the center of the cake, that says it fudgy in the middle.
- Let the brownies cool completely before cutting. It can be made up to 2 days in advance or it can be frozen beforehand also.
- To make the cookie dough frosting: Cream softened cream cheese and butter together in a large bowl.
- Add brown sugar and vanilla and evenly beat together.
- Add powdered sugar and whisk to evenly incorporate until smooth. (If you need to add a little milk to thin it, feel free to do so. I prefer my frosting thick so I never needed to)
- Next add in the milk, flour and mini chocolate chips.
- Wrap the frosting and set it in the fridge for about 15 minutes. It thickens up pretty nicely and make it easier to work with.
- You can also make it up to 2 days in advance and lake it out of the fridge 45 minutes before you want to use it to soften.
- To make the ganache: Heat the cream in a heavy bottom saucepan. When it reaches a simmer, take it off the heat and pour it over the chopped chocolate. Let it sit there for 3-4 minutes on the chocolate and then whisk until the chocolate has melted.
- Drizzle the ganache over the chocolate cake. It it drip over the sides. This is an easy way to decorate a cake.

Hi Gemma,
With what ingredient can we replace eggs in any baking recepie and by what quantity? And would it be effective? Since I have many vegetarian friends who prefers eggless bakes.
Thank you! Have a great day!
Hi there,
Take a look at this guide, it should help.

Hi 🙂
Can You tell me the measurements for the frosting in grams?
Thank you very much
Ella
Hi 🙂 Ella,
Cookie Dough Frosting Recipe
1 cup (8 oz/225g) cream cheese, softened
10 Tbsp (5oz/150g) butter, softened
1 ⅓ cup brown sugar
2 tsp. vanilla
4 Tbsp. milk, more if needed to reach desired consistency
1 cup flour
6 cups powdered sugar, more if needed to reach desired consistency. A cup of sugar will be about 125g in weight, but it depends on how you load the cup.
1 ⅓ cup mini chocolate chips.
I hope this helps,
Gemma 🙂
Hi Gemma,
i have 2 questions 🙂
1.) How can i figure the grams for the frosting out, because most of the ingrediens are measured in Cups
2.) Can i use a 9 Inch tin for the cake?
Yours Anna
Hi Anna,
your questions are answered in the instructions for this recipe. I used a 9 inch pan.
It is easy to convert from imperial measurements to grams. There are great tools for this online. I usually include these too in the recipes. A cup of powdered sugar is about 125g/40zs. This depends on how you load your cup.
Go back to the recipe and read it through,
Gemma 🙂
HI Gemma,
If i make the cake 2 days in advance, should i store it in the fridge in those 2 days? and do you think it will it be as good as it would be fresh?
Yes Kim, that will be totally fine to do. This cake gets better as it sits.
Best,
Gemma.
Thank you so much. Best cake ever.
Yay!!! delighted to hear that 🙂
Gemma.
Mine is 3 inches high, so it will yield about 1 inch high for each layer of cake. Is that enough?
hey gemma,
can you pls tell me how much my cake is supposed to rise. because i want to make sure that mine has risen properly. i find it a little short.
Hi Keisa,
I will answer all of the issues here re this recipe.
Brownies do not rise, they are not designed to rise, so they come out of the oven mush as you put them in, it is the nature of them. They do not have a raising agent, depending on the air in the batter for any rise.
I used a 9 inch pan for this, and cut it in three layers, they may look deeper in the photo than what they were. This cake is about 3 inches high when frosted.
I hope you have resolved this now, lightly mixing gives the best results,
Gemma 🙂
Hey Gemma!
I’m making your cake for some friends’ birthdays that are coming up soon.
If I make two 6-inch cakes instead of one 9-inch how would the baking time change?
Thank you,
Jessica
Hi Jessica,
yes it will take a little longer to cook because it will be thicker. Maybe give it another 10 minutes and then check it.
It might need a little more time even.
Gemma.
Thank you!
Hi Gemma
One more thing, In this cookie dough buttercream frosting, you added flour.
So eating raw flour isn’t a problem?
I am not sure that the flour I get where I live is edible or not.
So, Do I add flour in the frosting?
Hi there Smitri,
In any recipe, if you ad up the ingredient amounts, and subtract about 20% for evaporation in a baked item, you will get an approximate end weight.
eating raw flour is a problem in some places, but not all. Where I grew up, in Ireland, I never heard of an issue with raw flour, but it does happen. you need to find out what the rule is in your country. Occasionally there are warnings here in the US, usually specific to one mill, but be careful. better safe than sorry,
Gemma 🙂
Hi Gemma
So I did a research on internet.
And I found that some people claims that eating raw flour is a problem. And some say that eating raw flour is a very low risk. Some say that eating raw flour is a problem while some say it isn’t.
As you said, ‘better safe than sorry’, I read on internet how to heat treat flour at home to make sure it is safe to eat raw.
And I found that you can microwave flour for 1 minute 15 seconds at high, stirring after every 15 seconds or you can take flour in a pan or skillet and cook it till it is slightly brown by continuously stirring it.
Good research Smriti, thank you for sharing this with other bold bakers.
In western countries, when there is an issue with any food, it is notified to the public, through TV, Radio and the press.
I never heard of this being an issue in Ireland or the UK, when I lived there. I do know that there were warnings here in the US, in particular places from time to time. So, good idea to heat treat the flour, better safe than sorry!

How much cookie dough frosting will be made from this?
I want to use it on your cookie dough cupcakes
1 cup (8 oz/225g) cream cheese, softened
10 Tbsp (5oz/150g) butter, softened
1 ⅓ cup brown sugar
2 tsp. vanilla
4 Tbsp. milk, more if needed to reach desired consistency
1 cup flour
6 cups powdered sugar, more if needed to reach desired consistency
1 ⅓ cup mini chocolate chip
When you add all of these ingredients you arrive at about 3lbs (1785g) of finished frosting. This is a big mix, for a big cake.
You can reduce this, but measure on a digital scales if you can, it it easier. There are also many great conversion tools online.
Adding up the ingredients in a recipe, will give you the finished weight of ingredients.
In a baked recipe, if you want a finished weight, you need to subtract 20% or so for evaporation.
Next time, you can do this, you know how now!!
Gemma 🙂
Hi Gemma
How much cookie dough buttercream frosting will be made from this?
I want to use this in your small batch cookie dough cupcake.
Hi gemma,
Does the cookie dough frosting turns out to be grainy?
Hi there,
Cookie dough is uncooked, it is what it is! I do not find it grainy. If the flour where you live is safe to eat raw do try this, you can make a sample recipe to taste it. I hope this helps,
Gemma 🙂
Any substitute for cream cheese in the frosting.
hummm, only more butter so it is more of a butter cream frosting. You can sub butter instead.
Thanks,will try.
Hi gemma,
Can I bake it in a microwave.
Hi,
Unfortunately no. Check out my microwave recipe section for a mug brownie if thats what you are looking for.
Best,
Gemma.
hie ma’am…..i just wantd to knw whtr i shld substitute egg wd yogurt in mah brownie layered cake wd cookie dough frosting?do rply asap…..
Hi there,
There are a couple of substitutes you could use. Applesauce, Greek style yogurt, milled flaxseed. I like the flaxseed with chocolate, but the Greek (thick) yogurt should give a good result. These recipes are designed to be made with eggs, changing an ingredient will change the result, however these are the suggested substitutes,
Gemma 🙂
I really wanted to like this recipe. The frosting was great, but I made the cake the day before like Gemma suggested to another commenter but my cake fell apart. Also it was practically burnt on the outside while still almost raw on the inside. I doubt it’s my oven because I’ve successfully made other baked goods in it without such problems. Such a shame 🙁
Hi Sonali,
This does sound like a temperature problem in your oven, if the cake is overbaked in one part, and under in another there is an issue with the distribution of heat, or temperature fluctuations in your oven. It is worth checking this out. I know what I would do to check it is to make a cake I am familiar with, and it sounds like you are not having trouble with your usual bakes. An oven thermometer is a handy thing to have, and not an expensive item to buy, but you may not find one so easily where you live. This is my best guess!
I am sorry that you were disappointed with this recipe, it is usually a consistently good bake,
Gemma 🙂
Thank you for the reply, Gemma! I will try the oven thermometer 🙂 fingers crossed, I really want this to work!
Thank you Gemma! The idea of truffles is amazing! I’m guessing they’ll have to be refrigerated to be preserved. as far as my little research goes, most people suggest applesauce.
Hi Ann,
Yes, applesauce seems to be the number one choice for cake batters, it is really worth experimenting with this, to find the one which suits your type of baking too. good luck with this!
Gemma 🙂
