Chocolate Cola Cake with Peanut Butter Frosting

This is so good!  It was in last month's Southern Living and I made it on a whim this week.  I had all of the ingredients on hand.  The cake is super moist and the frosting tastes like peanut butter fudge.  I actually made two 8-inch square cakes instead of one 9x13 and passed the second cake on.  I got great reviews from the recipients!

Cake:

1 c cola
½ c buttermilk
1 c butter, softened
1 ¾ c sugar
2 eggs
2 t vanilla
2 c flour
¼ c cocoa
1 t baking soda
1 c chopped honey-roasted peanuts

Frosting:

¼ c butter
¾ c milk
1 c creamy peanut butter
16 oz package powdered sugar
1 t vanilla
 

1. Preheat oven to 350.  Combine cola and buttermilk in a 2-cup measure.
2. Beat butter at low speed until creamy.  Gradually add sugar, beating until blended.  Add eggs and vanilla; beat at low speed just until blended.
3. Combine flour and next two ingredients in a medium bowl.  Add to butter mixture alternately with cola mixture, beginning and ending with flour mixture.  Beat at low speed just until blended after each addition.  Pour batter into lightly greased 13x9 pan.
4. Bake at 350 for 30-35 minutes or until a wooden pick comes out clean.  Cool in pan for 10 minutes.
5. Meanwhile, prepare frosting:  Melt butter in a large saucepan over med heat.  Whisk in milk, and bring to a boil, whisking constantly.  Reduce heat to low, and whisk in peanut butter until smooth.  Gradually whisk in sugar until smooth; remove from heat, and whisk in vanilla.  Use immediately.  Pour over warm cake.
6. Sprinkle with chopped peanuts. As a note, I assumed the peanuts were an optional garnish and I did not have any on hand, so I didn't worry about it.  However, it was not possible for me to get the frosting completely smooth and you could see little pieces of powdered sugar.  I think the peanuts are to cover that up, so I would suggest them if you like peanuts alright.
