Chocolate Peanut Butter Cake

We are traveling again back to California to see friends, stopping at our kids home in Phoenix, AZ.  As soon as we walked in the door my SIL(son-in-law) met me with,”when are you going to bake and what are you going to bake?” I bypassed him to grab my sweet grandchildren and trying to sit and catch up on their latest episodes of Spongebob, SIL walks over to tell me he had the oven ready for baking. I have been in their house for 10 min, but know that if I’m going to get a minute to sit with my babies, I’m going to have to go bake something if for no other reason than to stuff it in SIL’s mouth. When I discover that their brown sugar is as hard as a piece of iron and there is no flour or granulated sugar in the house, I quickly pull out a chocolate cake mix. 

Realizing that I need to bake something quick and something that will hopefully enable SIL from making any more demands, I remembered that the kids always have peanut butter in the house so I throw Noah off my lap (anything for SIL to keep him happy as we told him that since he got Jodi on discount (she was, after all, over 25)she could not be returned thus, making it necessary for us to keep him happy so we don’t open our front door one morning and find Jodi standing there with 3 little hellions, oops I mean precious little grandchildren waiting on our front porch! So off the couch and into the kitchen! I made the chocolate cake according to directions for the 2 layer cake! After the layers are cooled I sliced them in half horizontally making 4 layers! Setting layers aside mix up the following:
2 cups powdered sugar
1/2 stick butter
1 cup of peanut butter
1/4 cream or half and half ( 1 tables at a time)
Mix these ingredients until well blended. Spread between the layers but not on top ( making 3 layers of peanut butter filling). Frost top and sides with chocolate frosting:
1 1 lb box of powdered sugar
1 stick softened butter
3/4 cup cocoa
1 teas vanilla
Cream to make desired spreading consistency
Mix all frosting ingredients together and mix until all limos are gone and mixture is well blended. Spread over sides and top of cake. Store in fridge until ready to serve.
