I made this for my dad’s birthday. I found it to be a lot moister than the usual German chocolate cake.
1 Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 9 inch pans.
2 In a medium saucepan, heat butter, yogurt, chocolate and cola until chocolate is completely melted.
3 In a large bowl, mix flour, sugar, and baking soda. Add chocolate mixture, buttermilk, eggs and vanilla. Beat until smooth. Pour batter into two 9 inch round pans.
4 Bake at 350 degrees F (175 degrees C) for 30 to 35 minutes, or until a toothpick inserted into cake comes out clean.
