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.

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.

My Best Ever Blondies recipe goes for the gold with indulgent butterscotch and chewy, brownie-like texture.

Author: Gemma Stafford

Servings: 9

Ingredients

  • 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

Instructions

  • 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.

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!

FAQs

Why are my blondies so gooey? ›

For gooey blondies, use a recipe with a small amount of flour (like ours), and don't over bake your blondies! The center should still be a little soft when you take them out of the oven. They will continue to set as they cool.

What's the difference between blondies and brownies? ›

Both have chewy textures. However, blondies have a much lighter and softer taste than brownies. The ingredients used in brownies are where the two recipes diverge the most. Blondies use vanilla extract and brown sugar instead of cocoa powder to get their flavor, while brownies use chocolate and cocoa.

Why don t brownies need baking soda? ›

Many brownie recipes don't contain baking powder or baking soda; these recipes tend to be for the dense, sometimes chewy, kind. Cakelike brownies usually contain a leavening agent, which helps give them their fluffy texture. The technique you use also makes a difference in the texture of the final product.

How do you tell if a blondie is undercooked? ›

Brownies and Blondies

The key is not under-baking them too much or too little. The toothpick test should produce a few errant crumbs stuck to the tester but not a smooth smear of batter.

How do you keep blondies moist? ›

Granulated sugar - simple fine white granulated sugar keeps these brownies moist. If you reduce the sugar they will not be as fudgy.

Why do my blondies taste like cake? ›

Tips. If your blondies are like cake when you take them out, it simply means they have been over baked – try less time or a lower temperature next time.

What is a substitute for butter in blondies? ›

If your recipe calls for melted butter, which is common in many quick breads, pancakes, brownies, blondies and some cakes, you can substitute an equal amount of neutral oil like safflower, canola or vegetable. If you want to experiment with flavors, try virgin coconut or olive oil.

What did blondies used to be called? ›

And before chocolate brownies came about, blondies were call brownies or molasses brownies... which to be honest is a bit confusing.

What does vinegar do in brownies? ›

I also mixed a little cocoa powder with confectioners' sugar to sprinkle over the cooled brownies before serving. Vinegar: White distilled vinegar is added to the batter to react with the baking soda, causing the brownies to rise. The vinegar also helps activate the cocoa powder for a more chocolatey flavor.

What happens if you put extra butter in brownies? ›

Adding Too Much Fat to the Recipe

Whether you use butter, margarine, or vegetable oil, putting too much in your brownie batter causes it to be greasy. Don't worry, you're not alone. Many people fall into this trap when trying to substitute butter with oil.

What is the best temperature to bake brownies? ›

Most recipes call for baking brownies at 350°. If a fudgy inside and crackly top is your goal, stick with that temperature. Brownies baked at 325° will take longer to bake and will become chewier in texture.

Can I use margarine instead of butter in blondies? ›

Yes! These chocolate chunk blondies work great with any kind of butter, so if you aren't dairy free you can absolutely use regular butter or margarine.

Can I put undercooked blondies back in the oven? ›

If your baked goods are undercooked:
  1. If they are only slightly undercooked, you can try returning them to the oven and baking for a few more minutes.
  2. If they are significantly undercooked, you may need to extend the baking time significantly.
Sep 14, 2023

Why is the brownie called blondie? ›

Chocolate was an early-20th-century innovation that quickly became the norm. At about mid-century, molasses brownies became known as blonde brownies. Soon after, the name shortened to blondies, giving the confection its own identity outside the brownie's shadow.

How do you fix gooey brownies? ›

Preheat the oven to 350 degrees Fahrenheit. Place the undercooked brownies back in the baking pan they were originally baked in. Bake for an additional 5-10 minutes, or until a toothpick inserted into the center comes out clean. Let the brownies cool completely before cutting and serving.

Can I eat undercooked blondies? ›

In the UK, eggs with the Red Lion seal of approval are safe to eat raw or undercooked. So you can slightly undercook blondies and brownies if you prefer a fudgier texture. However, if you don't cook them enough, you just have a tray of uncooked batter.

Are gooey brownies undercooked? ›

It's useful to know that the internal temperature of a regular cake should read 210°F for moist-but-not-fudgy fluffiness. So fudgy, gooey brownies will be done at around 165°F while cakey brownies will be done at around 210°F. The higher the temperature, the more cakey your brownies will be.

Why do my brownies always turn out gooey? ›

Problem 2: My brownies are too GOOEY

If you think about it, the ingredients that create that fudgy texture - the chocolate and butter - are completely liquid when hot, but solid at room temperature. We would never attempt to slice a brownie less than 2-3 hours after baking - it'll be a gooey mess.
