TRIED IT: Peanut Butter Brownie Trifle - YUMMMM!!! This was delicious! I also made my own whip cream instead of purchasing b/c I had heavy cream on hand already. Delicious and better the next day. I slightly undercooked my brownies and by day 2 they were pretty soft in the trifle but it still tastes very good. Everyone loved this. Passed along the recipe.
