This small batch of chocolate Frosted Brownie Blondies are a cross between a brownie and blondie,  The fudgy chocolate you love in a brownie combined with the butterscotch goodness of a blondie.  The bars are finished with a creamy chocolate butter-free frosting.

Frosted Brownie Blondies

Full disclosure:  this recipe happened by accident.  A happy accident, as it turns out.  I tried to get fancy and cook a butterscotch sauce for what was originally supposed to be my butterscotch and nuts blondies for two recipe.

Wouldn’t you know it – the butterscotch sauce wasn’t cool enough when I added the chocolate chips.  So you can guess what happened next.  I decided to just go with it, and BAM!  These little frosted brownie blondies were born.

And just for good measure, I’ve gone ahead and frosted these delightful dessert bars.  And I will be upfront and proud to say that the chocolate frosting is made without butter! 

Have I left you inspired for more blondie recipes? Try my peanut butter and chocolate chip small batch blondies for the ultimate gooey treat. Or, go gluten free and whip up a batch of my almond flour chocolate cherry blondies for two.

What is a Brownie Blondie 

Something delicious, obviously.  Kidding aside, they are simply a joining of a brownie and a blondie.  Here are some of the differences:

  • Brownies typically use granulated sugar.  These use brown sugar – just as you would a blondie.
  • Blondies usually only have intact chocolate chips.  The chocolate chips in these brownies have been melted along with the brown sugar (more on that in a moment).
  • Brownies may include cocoa powder for an extra chocolate flavor.  We are not using that here.   I wanted the mixture of flavors to come through with this recipe (i.e. chocolate + butterscotch). 

The result is a fudgy, soft bar – that still has that classic brownie crackly top – that may have you questioning why you haven’t tried these before!

Baking in a Loaf Pan

One of the essential kitchen tools when baking small batch desserts is the 9-inch x 5-inch loaf pan.  Depending on how you slice your brownies (or other baked treats you may bake in the pan), you can get 2, 4, 6 or even 8 slices of goodness. 

Because bars are pretty indulgent, I sliced them into smaller servings for 8.  Though, when you eat two at a time, you still go through them pretty quickly.  

You could certainly use a 6-inch square or round pan, but most likely you have a loaf pan already.  If not, I’ve included a link to the one I use above!

Equipment

Ingredients

Brownie Blondies

  • ½ cup light brown sugar
  • 3 tablespoons unsalted butter
  • 1 tablespoon water
  • cup semi-sweet chocolate chips
  • ½ teaspoon vanilla extract
  • 1 large egg, room temperature
  • ½ cup all-purpose flour
  • ½ teaspoon baking powder
  • ¼ teaspoon salt

Instructions
 

Brownie Blondies

  • Preheat oven to 350F degrees and adjust oven rack to the middle position. Line a 9×5 inch loaf pan with a piece of parchment paper to fit the length of the pan, and long enough the hang over the sides. This creates a sling to lift the brownies out of the pan.
  • In a small saucepan, heat the brown sugar, butter, water (this helps the sugar to dissolve evenly and not burn) and chocolate chips over medium heat until the sugar has melted – about 3 minutes. Remove from the heat and stir in the vanilla extract. Let cool to room temperature. Add the egg and whisk for about 1 minute to aerate and blend the ingredients well.
    ½ cup light brown sugar, 3 tablespoons unsalted butter, ⅓ cup semi-sweet chocolate chips, ½ teaspoon vanilla extract, 1 tablespoon water
  • Sprinkle (or sift) the flour, baking powder, and salt over the wet ingredients. Mix until no dry streaks remain.
    ½ cup all-purpose flour, ½ teaspoon baking powder, ¼ teaspoon salt, 1 large egg, room temperature
  • Pour the batter into the prepared pan and spread evenly. Bake for 20 to 22 minutes, or until a toothpick inserted in the middle comes out with moist crumbs. Cool the brownies in the pan set on a wire cooling rack for 10 minutes. Then lift out of the pan and cool completely on the wire rack.
  • Frost cooled brownies and cut into desired slices. The brownie blondies can be covered and kept at room temperature for up to 5 days.

    Made these today, turned out great! I made them vegan by substituting vegan butter for the regular butter and aquafaba for the egg. Thanks for the recipe! Will make these again for sure!

    I made these yesterday for our 4th of July festivities, and they turned out great! I live in Denver and often struggle to bake at altitude so happy to find your site. Look forward to trying more of your recipes!

    1. Hi Jen – So happy to hear you liked them! These may be one of my fav’s – I like the mix of brownie/blondie. And good to meet a fellow Coloradoan! Baking at altitude is a bit of challenge, but I’m slowly figuring it out 🙂
