SERIOUSLY MOIST CHOCOLATE CAKE
Source: the vast world wide web

2 cups sugar
1 cup oil (I used olive oil)
2 eggs
1 cup milk (I only ever buy 1%)
1 cup HOT coffee
2 tsp vanilla extract
3/4 cups cocoa powder
2 cups cake flour
1 tsp salt
1 tsp baking powder
2 tsp baking soda
1/2 cup sour cream
-----
1. Preheat oven to 325 degrees.
2. Grease and flour your cake pan(s) (2 round, or 1 sheet).
3. Add all dry ingredients (except sugar) to a bowl and whisk to combine.
4. In mixer, add sugar and oil and mix to combine.
5. Add eggs one at a time until incorporated.
6. Slowly add milk, coffee and vanilla extract.
7. Add dry ingredients in increments with mixer on low speed.
8. Add sour cream and stir to combine. (I used Greek yogurt)
***this batter is super thin. don't worry!!!***
9. Pour into cake pans and transfer to oven.
10. Bake for 40 minutes or until toothpick inserted comes out clean.

I topped both the cake and cup-cakes with cream-cheese frosting, though the next time I may just use a fresh whipped cream. The cake is super rich and moist and really doesn't need a heavy frosting, though the cream cheese frosting was yum.
