Chocolate Peanut Butter Trifle

I found this recipe on Tasty Kitchen.  My husband wanted something with chocolate and peanut butter that was a dessert and not a cookie.  It was delicious and so easy. 

1 box Devil's Food Cake Mix (18 Ounce Box)
1 package Instant Vanilla Pudding (3.9 Oz)
1 package Instant Chocolate Pudding, 3.9 Oz
3 cups Cold Milk, Divided
1/4 cup Peanut Butter
1 tub Whipped Topping (8 Oz), Defrosted, Divided
1 package Mini Peanut Butter Cups (12 Ounce Package, Chopped)

Prepare cake mix as directed by combining the mix with the additional required ingredients specified in cake mix package (typically water, eggs and oil). Bake in 9 x 13 pan at the time/temp required by the package instructions. Cool. Cut into 1 inch cubes.
Empty pudding packages into separate bowls. Add 1 1/2 cups of milk to each bowl. Beat with whisk for two minutes. Add peanut butter to the vanilla pudding. Mix until combined. Stir 1/2 cup whipped topping into each bowl.

 Layer half of the cake cubes into trifle bowl. Cover with chocolate pudding, half of the remaining whipped topping and half of the chopped peanut butter cups. Add the rest of the cake cubes, the vanilla pudding mixture and the remaining whipped topping.

 Top with remaining chopped peanut butter cup candies.
