Ingredients

12 tablespoons unsalted butter, at room temperature, plus more for pan

1 cup all-purpose flour

3/4 cup unsweetened cocoa powder

1/4 teaspoon baking powder

1/2 teaspoon coarse salt

1/2 cup milk

1/2 teaspoon freshly squeezed lemon juice

1 teaspoon pure vanilla extract

1 1/2 cups granulated sugar

3 large eggs

Preparation

Preheat oven to 350 degrees. Butter a 10-inch bundt pan.

Sift together flour, cocoa powder, and baking powder onto a piece of parchment paper or into a bowl. Add salt and set aside. In a small bowl or measuring cup, stir together milk, lemon juice, vanilla, and 2 tablespoons water; set aside.

Combine butter and sugar in the bowl of an electric mixer fitted with a paddle attachment and beat on medium-high speed until light and fluffy, about 2 minutes. Add eggs, one at a time, mixing well after each addition. Reduce speed to low and add flour mixture in 3 additions, alternating with the milk mixture and ending with the flour mixture, mixing well after each addition. Pour into prepared pan.

Bake until a cake tester inserted into the center comes out clean, about 50 minutes. Let cool to room temperature.
