Peanut Butter Chocolate Bars!

OH MY THESE ARE GOOD!!!!
Combine:

1 pkg. plain yellow cake mix

1 stick melted butter

1 c. creamy peanut butter

2 eggs

Press this into a 9X13 pan reserving 1 1/2 c. of the mixture to crumble on top.


Melt:

1 (12 oz) pkg. chocolate chips

1 can sweetened condensed milk

2 T. butter

Melt on low heat in a small pot. Remove from heat and add:

2 tsp. vanilla

1 c.coconut (optional)

Spread chocolate mixture over the mixture pressed in the pan and then crumble the 1 1/2 of reserved cake mixture on top. Bake for 20-25 minutes at 325 degrees. Cool completely before cutting into bars. *** Very important to wait. I thought I didn't have to and learned otherwise.
