You'll need:
- 1 box red velvet cake mix
- or 1 box chocolate cake mix + 2 Tbs red food coloring (1 small 1-oz container)
- 3/4 c sour cream
- 1/4 c mayonnaise
- 1/2 c oil
- 1/2 c water
- 3 eggs
- 1 tsp vanilla extract
- 1 c semi-sweet chocolate chips
For the frosting:
- 2 Tbs butter, at room temperature
- 4 oz (half block) cream cheese, at room temperature
- 1 1/4 c powdered sugar
- 1/2 tsp vanilla extract
Put all cake ingredients in a stand mixer and mix until fully blended. Pour into a greased bundt pan (I use Pam for Baking - and spray liberally) and cook at 350 for 45 minutes.
Let cool in pan, then shake the pan to loosen the cake and flip onto a plate.
Mix the butter, cream cheese, powdered sugar, and vanilla in a stand mixer or by hand (I just used a spoon). Put into a piping bag, or a quart-sized freezer bag with a corner snipped off, and pipe onto the totally cooled cake in whatever pattern you want!
