Brown Butter Toffee Blondies

Since it’s October, I’m making recipes inspired by some of my favorite Halloween candies! This week, I created a recipe for Heath Bar inspired Brown Butter Toffee Blondies. These Brown Butter Toffee Blondies are topped with a soft chocolate icing and crunchy toffee bits. If you are a toffee lover, these blondies are the recipe for you!

How to Make Brown Butter Toffee Blondies

Brown Butter Toffee Blondies

Brown butter has a great flavor itself, but these Blondies are made with all brown sugar and more toffee bits baked in to really take them to another level. First, brown the butter in a saucepan over medium heat. Heat the butter until all the water evaporates and the milk solids start to brown. Be sure to stir consistently to prevent them from burning. Brown butter is delicious, but burnt butter is not! Once browned, pour the butter into a mixing bowl, making sure to scrape in as many browned milk solids as you can. That’s where the flavor is! If you don’t want to do more dishes, you can make the batter in the saucepan, but be sure to allow it to cool before adding the rest of the ingredients. You don’t want scrambled eggs in your blondies! I find that transferring the brown butter to a separate mixing bowl allows it to cool faster.

Once the brown butter has cooled slightly, add the brown sugar and mix to combine. Add the eggs, one at a time, making sure to stir after each addition. Next, add the vanilla extract, baking powder, and salt. Finally, stir in the flour and mix until fully incorporated.

Baking

Pour the batter into a prepared 8-inch by 8-inch baking pan and bake at 350°F until the edges of the blondies are browned and the top is golden brown, about 30 minutes. The blondies might look done around 20 minutes, but give them the extra time so that the center can cook through. Once baked, set aside while you make the chocolate icing.

Chocolate Icing

The icing on these Brown Butter Toffee Blondies is similar to that on a Texas sheet cake. It is made in a saucepan over the stove, poured over the dessert, and sets into a soft icing when cooled. This icing is a favorite of mine because it is easy to make, takes just a simple pour to decorate, and is beautifully shiny. To make the chocolate icing, place the butter, milk, and cocoa powder in a saucepan over medium heat. Stir consistently until the butter is melted and bring to a simmer. Once gently boiling, take the pot off the heat and add the vanilla extract, salt, and powdered sugar. Stir consistently until the mixture forms a smooth liquid. It will have a thicker consistency, but should still be pourable. Pour the warm icing over the blondies and spread to the edges. Once the icing is slightly set, sprinkle the top with toffee bits and set aside to cool fully.

Serving and Storage

It’s easiest to serve these blondies directly from the pan because the frosting is a softer one. The Brown Butter Toffee Blondies will store well in a covered container at room temperature for 3-4 days, but won’t freeze well. If you want to freeze the blondies, leave them unfrosted! Slice and wrap each individual bar in plastic wrap before freezing, then allow to come to room temperature to enjoy.

These Brown Butter Toffee Blondies have a delicious, buttery caramel flavor, a sweet, soft chocolate icing, and crunchy toffee pieces on top. If Heath Bars are your favorite candy, you definitely need to try out this recipe!
