If I asked you to describe your perfect brownie, you might use words like chewy, cakey, and fudgy. Two words you likely wouldn’t use — crispy and crunchy — are actually perfect for describing brownie brittle, a sweet snack you may have seen packages of at the grocery store. Studded with chocolate chips or toffee bits, this chocolatey confection channels the best parts of the brownie (read: crunchy corners) and bags them up for easy enjoyment. With this recipe, you can make a big batch of brownie brittle whenever you want.

What Does Brownie Brittle Taste Like?

Brownie brittle tastes just like your favorite cocoa-based brownie: rich, chocolatey, and bittersweet. Because the two are made with many of the same ingredients, the only difference between bar-style brownies and this brittle is the texture. Traditional baked brownies have either a chewy, cakey, or fudgy texture. These sweet shards, on the other hand, have a crunch that’s on par with a crispy cookie.

Tips for Making Brownie Brittle

  • Use egg whites only. Because egg yolks can tenderize and soften the sweet, I use frothed egg whites to give the batter structure and a slight lift. 
  • Stick with granulated sugar for sweetening. The molasses in brown sugar adds chewiness to brownies — a quality we want to avoid in this recipe. Instead, I reach for granulated sugar to add sweetness.
  • Spread your batter thinly. I call for lining a rimmed baking sheet with a silicone baking mat or parchment paper before spreading the batter into a very thin layer, which bakes up nice and crispy.
  • Cool the brownie brittle completely. The thin, baked brownies will continue to crisp as it cools, so give it about 20 minutes before breaking apart. 

What Are the Best Ways to Eat Brownie Brittle?

Brownie brittle satisfies my mid-afternoon craving for something sweet and crunchy in a single bite. Besides eating it as a snack, there are many other ways to enjoy the brittle: You can add broken-up bits to the top of an ice cream sundae, crumble it into smaller pieces and use them in the center of a layer cake or trifle, or stir it into a sweet snack mix

Nutritional Info

Ingredients

    • 2

      large egg whites

    • 1/2 cup

      granulated sugar

    • 1/4 cup

      unsweeteened natural cocoa powder

    • 1/4 cup

      vegetable or canola oil

    • 1/2 teaspoon

      vanilla extract

    • 1/2 cup

      all-purpose flour

    • 1/2 teaspoon

      kosher salt

    • 1/4 teaspoon

      baking powder

    • 1/2 cup

      mini chocolate chips, toffee bits, finely chopped nuts, or a combination

    Instructions

    1. Arrange a rack in the middle of the oven and heat the oven to 325°F. Line a rimmed baking sheetwith parchment paper or a silicone baking mat.

    2. Place 2 large egg whites in a large bowl and whisk until foamy. Add 1/2 cup granulated sugar, 1/4 cup unsweetened natural cocoa powder, 1/4 cup vegetable or canola oil, and 1/2 teaspoonvanilla extract. Whisk until smooth.

    3. Place 1/2 cup all-purpose flour, 1/2 teaspoon kosher salt, 1/4 teaspoon baking powder in a medium bowl and stir to combine and remove any large lumps. Add to the egg white mixture and stir until just combined.

    4. Pour onto the baking sheet and use a small offset spatula to spread into a thin, even layer 1/8- to 1/4-inch-thick, going almost to the edges of the pan. Sprinkle with 1/2 cup mini chocolate chips, toffee bits, finely chopped nuts, or a combination.

    5. Bake until firm to the touch and slightly darker around the edges, about 25 minutes. Transfer to a wire rack and let cool completely, about 20 minutes. The brownie brittle will crisp as it cools. Break into pieces with your hands.
