Hi Bold Bakers!

I have a secret… Although I don’t often admit it, I actually prefer butterscotch to chocolate. I know all of you chocolate-loving Bold Bakers are thinking no way, lady – well, my Best Ever Blondie Recipe might just convert you.

Decadent, chewy butterscotch makes this hands-down the best blondie recipe.

What Is A Blondie And How Is It Different From A Brownie?

If you’ve never tasted one before you might be asking what is a blondie and how is it different than a brownie. Well, it’s really simple and it’s pretty genius. A blondie dessert is a fudgy baked bar with the same textural elements as a brownie. Brownies are balanced with a magic ratio of oil, sugar, flour, chocolate, and eggs.

A bit of flour, rich eggs, and sweet sugar provide brownies with moisture and allow them to cook without being “set” entirely. These elements form that unmistakable fudge center and can be found in my blondie recipe as well.

While a brownie uses dark chocolate to flavor the batter, blondies get their blonde color and butterscotch flavor from caramel-like brown sugar, aromatic vanilla extract, and rich white chocolate. The result is a unique caramel flavor and brownie texture, hence “blonde brownies” or blondies.

What makes this one of my best desserts is not just the taste but the simplicity of its process. This blonde brownie recipe is a foolproof, one-bowl recipe that can be made in under 15 minutes.

Because this blondie recipe is made with such simple baking ingredients, it’s the kind of treat that can be made at the drop of a hat. I love to make these blondies for all kinds of occasions but I am known to make them for no reason at all.

What You’ll Need To Make Blondies

How To Make Blondies

Thankfully this blondie recipe is super easy to make (and don’t forget to get the full recipe with measurements, on the page down below):

  1. Preheat the oven.
  2. Butter 8X8-inch tin with parchment paper.
  3. Melt unsalted butter in the microwave.
  4. In a medium or large bowl, whisk melted butter and brown sugar.
  5. Stir in the egg and vanilla.
  6. Add the flour and salt into the bowl and mix using spatula.
  7. Fold in the white chocolate chips.
  8. Transfer batter into tin and pop in the oven for a bake time of 30 minutes.
  9. Once golden brown, take the blondies out and allow them to cool completely.
  10. Cut brownies into nine squares and enjoy.

How To Make Brown Sugar

Should you be unable to find brown sugar in your country, be sure to check out my homemade brown sugar recipe.

.With just two ingredients, throwing together your own dark brown sugar is simple. I personally love to make my own basic ingredients as it means I never run out of building blocks for a great dessert.


What Can I Add To Blondies?

I love the flavor of these best blondies so much that I don’t really think they need anything else. That being said, feel free to add your favorite nuts, like chopped walnuts, and toppings to take these blondies above and beyond.

My Best Ever Blondies recipe goes for the gold with indulgent butterscotch and chewy, brownie-like texture.
Author: Gemma Stafford
Servings: 9


  • 1 cup (8oz/225g) butter, melted
  • 2 cups (12oz/340g)brown sugar
  • 2 eggs (room temperature)
  • 1 tablespoon vanilla extract
  • 2 cups (10oz/284g) all-purpose flour
  • 1 teaspoon salt
  • 11/2 cups (9oz/255g) white chocolate chips


  • Preheat your oven to 350°F (180°C). Butter and line an 8 x 8 inch tin with parchment paper and set aside.
  • Melt the butter in the microwave for 25-30 seconds or in a pot on the stovetop.
  • In a medium bowl whisk together the melted butter and
    brown sugar.
  • Make sure that the mixture isn't hot, then stir in the egg and vanilla.
  • Using a spatula, mix in the flour and salt. Once the batter is evenly combined fold in the white chocolate chips.
  • Transfer the batter into your lined tin, and bake for roughly 30 minutes, until the top is golden brown, and the middle is just set. To achieve the perfect blondie on the inside you want to make sure you bake them for just the right amount of time and don't over bake them.
  • Allow the blondies to completely cool in the tin before removing them from the parchment paper and cutting.
  • Cut the blondies into 9 squares and enjoy warm preferably. Cover and store at room temperature for up to 3 days.

Mine came out oozy and raw despite the skewer being 100% clean. The flavour was nice but inedible due to being raw and oozy. I would say there is too much salt though – perhaps salted butter with no added salt or unsalted butter with added salt would be better. I followed this recipe exactly and I have absolutely no idea what happened.

These are absolutely delicious and are a firm family favourite.

I do have a question though, anyone know how many calories are in this please.

if anyone is thinking of making this, add 1 teaspoon baking powder and half teaspoon baking soda. without it, this recipe came out gooey and raw no matter how long I baked it because there are no levelling agents!

I made this for the first time yesterday and they turned out perfect!!! I didn’t use salted butter though and that worked perfectly for me! I also added half a cup of butterscotch chips and they were delectable! Thanks so much, Gemma for your easy to follow, delicious recipes!

Although I’ve had sucess with other recipes on the site, unfortunately these didn’t work out for me. Even though I baked them for 45 minutes, they were still underbaked in the middle, even though the perimeter were nice and golden. They came out greasy and overly sweet. I’ll try to put them back in the oven to see if they can be salvaged, but if I ever make another attempt, I’ll definitely cut back the sugar by about half.

These are DELICIOUS. I use chunks of white chocolate because I can never find chocolate chips. They are soooo gooey and yummy in the middle. We had them with some raspberry sorbet and it was just amazing!

I wish I’d read the reviews beforehand. I’m an experienced baker and followed the recipe exactly, used the right ingredients, and I have a fairly new high quality oven. They turned out completely uncooked even after an hour of baking, and I mean not just a little gooey in the middle like brownies and blondies sometimes are, but pretty much completely liquid aside from the edges. I don’t know how this worked for some people.

Awesome recipe. I only used 1.5c of sugar, but was a bit concerned about the vanilla extract. Your recipe calls for 1 tablespoon, but I notice in your video you only used 1 tsp. Anyhoo, it turned out perfectly. I have a fan forced oven and put the temperature at 165°c and baked for 30 minutes.

These were incredible! First time I’ve ever made any type of brownie from scratch. Great recipe, I used unsalted butter and they tasted great! Middle pieces were a little oozy when still warm but after cooling down to room temperature they were perfect!
Will definitely make again!
