10 tablespoons unsalted butter
3/4 cup plus 2 tablespoons unsweetened cocoa powder
1 1/4 cups granulated sugar
1/4 teaspoon salt
1/2 teaspoon pure vanilla extract
1/2 cup all-purpose flour
Flaky Sea Salt
Preheat oven to 325°F. Coat an 8×8-inch square baking pan with cooking spray. Set aside.
Combine the butter and cocoa powder in a medium, microwave-safe bowl and microwave 30 seconds or until melted. Stir in sugar, salt and vanilla. Cool slightly.
Add the eggs one at a time, beating after each one until batter is thick and well combined. Add the flour and beat until just combined. Pour batter into prepared baking pan.
Bake 28 to 35 minutes or until set. Remove from oven and top with Cashew Butter Cups and let them melt all over the brownies. Sprinkle with flaky sea salt. Cool completely and enjoy!
