Fudgiest Espresso Cashew Brownies Recipe

One Bowl Baking

Great baked goods don't necessarily require multiple pots and pans. These easy recipes require just one bowl, which means less time, less clean up, and more eating.

Fudgiest Espresso Cashew Brownies Recipe

Decadent, fudgy brownies with a kick of espresso and a handful of crunchy sweet cashews. Extra whisking will give you a crustier top.

Notes: Whisking the mixture well helps to dissolve the sugar and contributes to a crackly crust. The sugar should end up mostly dissolving, and the mixture should appear smooth and glossy. For fudgy brownies, avoid overbaking.
