Preheat oven to 350ºF, grease, and dust with cocoa powder 2x8” or 3X6" cake pans, and set aside.
Combine the flour, sugar, malt powder, cocoa powder, baking powder, baking soda, and salt in the bowl of your stand mixer and mix on low for 1 minute.
2 cups All-purpose flour, 1½ teaspoon Baking powder, 1 teaspoon Baking soda, ½ teaspoon Salt, 2⅓ cup Granulated sugar, 1 cup Cocoa powder, ¼ cup Malt powder
Mix the eggs, buttermilk, oil, mayonnaise, and vanilla in a separate bowl, then add to the flour mixture and mix on medium speed for 2 minutes. Scrape the bowl as needed.
2 Eggs, 1 tablespoon Vanilla extract, ½ cup Oil, 1 cup Buttermilk, ¼ cup Mayonnaise
Bring the speed down, the hot coffee and mix until just mixed. DO NOT OVERMIX.

The batter will be thin and that’s okay. Pour the batter into the prepared pans, and bake for 40-45 minutes until an insert into the center comes out clean.
Cool the cakes in the pan for about 15 minutes, then invert onto wire racks to cool completely before frosting.
