The brownie-baking extravaganza continued last week with these midnight brownies, which I’ve named as such because they are delightfully dark. These treats use Dutch process cocoa, which is made by washing cocoa beans in a potassium solution to neutralize its acidity before they’re processed into powder.
The end result of this process (apparently pioneered by the Dutch) is a darker cocoa powder, which yields a different type of flavor in baked goods. Dutch process cocoa is also usually paired with baking powder, an acidic raising agent, rather than baking soda, which needs to react with an acid to create a rise in baking. Science was never my strong suit, but I think if I had learned it with baking-related examples, I would’ve understood it much better.
- 1 cup unsalted butter
- 2 1/4 cups sugar
- 1 1/4 cups Dutch process cocoa
- 1 teaspoon salt
- 1 teaspoon baking powder
- 1 tablespoon vanilla extract
- 4 eggs
- 1 1/2 cups flour
Preheat oven to 350 degrees. Lightly grease a 9 x 13 baking tin; sprinkle the bottom with sugar if desired for a crunchy bottom crust.
In a saucepan over low heat, melt butter, then stir in sugar and return to heat very briefly, until its hot – between 110 to 120 degrees – it will look shiny as you stir it (this helps the sugar dissolve better, which yields a crunchy top on the brownies). Transfer the mixture to a large bowl and stir in the cocoa, salt, baking powder, and vanilla. Stir in eggs, then flour, until batter is smooth.
Pour into prepared baking tin and bake for 28 to 30 minutes, until brownies are set and a cake tester inserted in the center comes out clean. Cool completely before cutting into squares. Store in an airtight container at room temperature. Makes 24.
