Peanut butter fluff bars

I have been seriously craving peanut butter and chocolate lately so expect alot of recipes involving those to come :) I found this recipe I based this off of in an old cookbook with Kentucky recipes and it only had half the peanut butter and fluff I just figured if a small jar of marshmallow fluff is good why wouldn't the bigger jar be even better lol.  

Peanut butter fluff bars

1 package of devils food cake

1 stick of butter melted

1 14oz jar of marshmallow fluff

1/2 cup creamy peanut butter

 

melt butter and mix in with cake mix. Grease a 9x13 baking dish put all but 1 1/2 cups of cake mix in baking dish. Then in a separate bowl mix peanut butter and fluff together and spread over the cake mixure. Then crumble the remaining 1 1/2 cups of cake mix on top bake at 350 degrees for 20 minutes and enjoy!
