Instructions

Make the Cake:

  • Preheat oven to 350°F. Prepare cupcake pans with liners or grease and flour cake pan(s).
  • Whisk together sugar, cocoa, salt, baking powder, baking soda, and flour in a large bowl. Set aside.
  • Whisk oil, eggs, water, buttermilk, and vanilla in a large measuring cup or bowl.
  • Pour wet ingredients into dry ingredients and whisk until smooth. Batter will be thin.
  • Pour into prepared pans and bake as directed, or until a toothpick comes out clean from the center. Cool completely before frosting.

Make the Frosting right before using:

  • Add powdered sugar and cocoa to a very large bowl. Whisk to combine and get out any lumps.
  • Pour in unsalted butter and mix with a hand mixer or stand mixer until crumbly, then add vanilla and salt.
  • Add milk and mix until frosting is smooth and the desired consistency. Use immediately.
  • Bake Time:
    24 cupcakes: 13-16 minutes
    Two 9-inch rounds: 28-35 minutes
    9x13-inch pan: 35-40 minutes

Notes

  • Use Unsweetened Cocoa or Hershey's Special Dark Cocoa but NOT Dutch Process
  • Substitute 1:1 gluten free AP flour to make these gluten-free
  • For the buttermilk, you can substitute milk or non-dairy milk by adding 1tsp vinegar or lemon juice to the wet ingredients.
