Preparation

  2. In a mixing bowl, whisk together the flour, cocoa powder, baking powder, and salt.
  3. In another bowl, beat the eggs and granulated sugar until pale and fluffy, about 2-3 minutes.
  4. Gradually mix in the milk, vegetable oil, and vanilla extract. Fold the dry ingredients into the wet ingredients.
  5. Pour the batter into the prepared pan and bake for 12-15 minutes or until a toothpick comes out clean. Cool completely in the pan.
