1 cup unsweetened cocoa powder
*1 tbsp instant coffee (for extra darkness and flavor!)
2 1/2 cups all-purpose flour
2 cups sugar
1 1/2 teaspoons baking powder
1 teaspoon baking soda
1 teaspoon salt
3 large eggs
3/4 cup vegetable oil
1/2 cup sour cream
2 teaspoons vanilla extract
Preheat the oven to 350 degrees F.
Prepare pans (grease & parchment the bottom) — either two 9″ rounds or one 9×13 pyrex (will be a thick cake)
Whisk the cocoa powder, instant coffee and 1 1/2 cups boiling water in a medium bowl until smooth; set aside. Add the eggs, veggie oil, sour cream and vanilla to the stand mixer bowl, mix until smooth. Add in chocolate mixture. Mix in the dry ingredients (sifted together) until combined into a thin batter.
Bake until a tester comes out clean, about 30-40 minutes. Cool slightly, then move to a cooling rack.
