Preheat oven to 350℉. Prepare brownie mix according to package directions. Stir in peanut butter chips.
Spread the batter into a 13 x 9 baking pan and bake for 20-25 minutes. Be careful not to overbake. To test if the brownies are done, insert a toothpick into the center, and if it comes out clean, the brownies are done. Let them cool on a cooling rack, Once browniies are completely cooled, cut into 3/4 inch squares.
Cut peanut butter cups in half and set aside 1/3 cup for top of trifle.
In a large mixing bowl, mix the puddings and the milk for 2 minutes. The pudding mix will be thick, Add peanut butter and vanilla and mix thoroughly. Fold in 1½ cartons of whipped topping and mix well.
Place 1/3 of brownies in a 5-quart glass bowl and top with 1/3 of the peanut butter cups. Spoon 1/3 of the pudding mix onto this layer. Repeat layering twice more.
Top the final pudding layer with the remaining whipped topping and garnish the top with the reserved 1/3 cup of peanut butter cups.
Refrigerate until completely chilled.
