  • 1 cup buttermilk
  • 2 large eggs
  • 1/2 cup canola oil
  • 2 tsp vanilla
  • 1 3/4 cups Cup 4 Cup Gluten Free Flour
  • 3/4 cup cocoa powder
  • 2 cups sugar
  • 2 tsp baking soda
  • 1 tsp baking powder
  • 1 tsp salt
  • 1 cup freshly brewed coffee
  • For buttercream:
  • 2 sticks of European unsalted butter Plugra
  • 2 - 2 1/2 cups of powdered sugar
  • 1 tsp vanilla extract
  • tiny pinch of salt
  • 1 package of natural food coloring
  • 1 tbsp of milk or heavy cream if needed for thinning


  • Preheat oven to 350°.
  • Spray two round 9-inch cake pans with cooking spray and line with round parchment sheets.
  • In the bowl of an electric mixer add first wet ingredients, buttermilk through vanilla. Mix on low until combined with the paddle attachment.
  • Add the dry ingredients all at once, flour through salt and mix on low using a spatula to scrape the sides.
  • Add fresh coffee and mix just until combined. Do not overmix.
  • Pour batter into two cake pans dividing evenly.
  • Place on middle rack and cook for about 25-35 minutes rotating once.
  • Check with a toothpick after 25 minutes to see if it's done. If not put back in for five minutes and check again.
  • Let cool 30 minutes.
  • For the icing:
  • Place butter in mixer and beat for a few minutes.
  • Add sugar in 1/2 cup increments and beat well, using a spatula to scrape down the sides.
  • Add the vanilla and beat.
  • Add the food coloring and continue to beat.
  • Check out the texture. If you want it thinner add a bit of milk or cream. I added just a teaspoon.


Add more milk to the buttercream frosting if you want a thinner icing.
