Mix cake mix and kombucha well, but do not overmix. Pour into an oiled baking dish. Bake at 350°F for the time on the package for your sized dish. Mine was 9 ½" x 7 ½", so I baked mine for 37 minutes. The cake is done when a toothpick comes out easily and almost clean. Let cool before frosting it.
3 Ingredient Chocolate Frosting
Mix all ingredients until smooth. Refrigerate for at least 30 minutes, then spread on cake.
Notes
Make sure to follow instructions on cake mix package for your sized baking dish. The serving sizes are a bit large (for me) - you may find yourself eating ½ the serving size.This cake recipe will last 3 days in an airtight container at room temperature. Storing it in the fridge will dry it out. If you frost it with the included frosting recipe, you'll need to store it in the fridge.
