Peanut butter fudge bars

 
Adapted from www.the-girl-who-ate-everything.com
1 pkg yellow cake mix
1/2 c. butter, melted
1 c. creamy peanut butter
2 eggs
2 c. chocolate chips
1 14 oz can sweetened condensed milk
2 T. butter
2 t. vanilla

Preheat oven to 325 degrees. Combine cake mix, melted butter, peanut butter & eggs in large bowl. Press the cake mixture into a 9X13 pan, reserving 1 1/2 c. to crumble on top.
In a small pot, melt chocolate chips, sweetened cond. milk & 2 T. butter. Stir until thick like soft fudge. Remove from heat & stir in vanilla.
Spread chocolate mixture over cake & then crumble the remaining 1 1/2 c. cake mixture on top evenly ( I take a piece & make it kind of flat & place it on top)
Bake for 20-25 minutes. Cool completely before cutting into bars.
