The easiest, fluffiest oat flour chocolate cupcakes come together in minutes and never fail to please. So tender and decadent, you will absolutely not be able to tell that these cupcakes are gluten free.
In a medium bowl, whisk together the oat flour, sugars, cocoa powder, baking soda, baking powder, and salt.
In a large bowl, whisk together the olive oil, eggs, buttermilk, and vanilla. Stir and whisk the dry ingredients into the wet ingredients and stir very well to combine. Stir in the coffee and stir until batter is smooth and combined.
Pour batter evenly into the prepared pans and preheat oven to 350°F. Let batter rest while the oven heats, about 15 minutes.
Place pan in the oven and bake for 35-40 minutes, checking at 35 minutes, until a toothpick in the center comes out clean. Remove from oven and let the cupcakes cool in the pan on a wire rack for 10 minutes, then remove the cupcaes to the rack to cool completely.
