I always use Kosher salt in my kitchen! If using table salt, start with half the amount and adjust to taste, as it is much "saltier" by volume.
Instructions
Chocolate Cake
Preheat an oven to 350°F and generously grease a 9x13 pan or line with parchment paper.
Combine the flour, sugar, cocoa powder, salt, baking powder and baking soda in a large mixing bowl. Mix until fully combined.
In a large measuring cup or medium bowl whisk together the buttermilk, vanilla extract and eggs. Pour the milk mixture into the dry ingredients and mix well.
Mix the freshly brewed coffee with the coconut oil (or, if using canola or vegetable oil, combine it with the buttermilk mixture). Stir until the coconut oil is completely melted. Then, add the coffee mixture to the cake batter and mix until fully combined. Pour the batter into the prepared pan.
Bake for 30 minutes or until a toothpick inserted in the middle of the cake comes out clean. Cool completely before frosting.
Buttercream Frosting
Cream the butter in a mixer until fluffy. Gradually add the powdered sugar, a little at a time. Then, mix in the vanilla extract and heavy cream. Beat on medium for 2-3 minutes, or until light and fluffy. Frost the cake and decorate with sprinkles.
If you want to pipe hearts on your Valentine's cake, set aside about ½ cup of the buttercream before frosting the cake. Then, divide the ½ cup into two portions. Color one portion red and the other pink.
