If you love peanut butter as much as my family, you will love this recipe. These bars are so rich and good! I got the original recipe
here. Next time I'm going to try them with a chocolate cake mix.

Peanut Butter Gooey Bars (adapted from Love Veggies & Yoga)
crust:
1 box cake mix (white, yellow, butter flavor, or chocolate)
1/2 c. (1 stick) butter, melted
1 t. vanilla
1 egg
middle:
1 (14 oz.) can sweetened condensed milk
2/3 c. marshmallow cream
2/3 c. peanut butter
1 t. vanilla
top:
1 c. chocolate chips
2/3 c. reeses pieces
frosting:
1/2 c. chocolate chips
1/2 c. peanut butter
3 T. butter
For crust, mix cake mix, butter, vanilla and egg until you get a stiff dough.
Press into a greased 9x13" pan.
For middle layer, combine sweetened condensed milk, marshmallow cream, peanut butter and vanilla.
Pour over crust.
Sprinkle with chocolate chips and reeses pieces.
Bake at 350 F for 20-23 minutes. (It will seem really jiggly when you take it out, that's good!)
For frosting, melt chocolate, peanut butter and butter in a microwave safe bowl. Mix until smooth.
Drizzle over warm bars.
Allow to cool completely and then refrigerate for several hours.
Cut into squares and enjoy!
