Set out two medium size bowls and a sifter. In one bowl, add flour, sugar, cocoa powder, espresso powder (delete if using warm coffee), baking powder, baking soda, and salt. Place sifter in empty bowl. Scoop dry ingredients, place in sifter, and sift dry ingredients together. Sifting the dry ingredients together insures an even distribution of the baking powder, baking soda, and cocoa, which will make the crumb of the cake light and uniform. If you don’t have a sifter, make sure to thoroughly whisk the dry ingredients together.
