1. In a large trifle dish, layer the chocolate pudding, peanut butter mousse, brownie crumbles, and Tagalong cookies in layers.
2. Once the trifle dish is layered to the top, garnish with the green “moss” cake crumbles.
3. This can be garnished with gummy worms, edible flowers, or rock candy. Have some fun with it! We chose to make edible white chocolate mushrooms using silicone molds we found on Etsy.

For the homemade peanut butter mousse:

1. In a large bowl, mix together the peanut butter, cream cheese, and powdered sugar until smooth and combined. Set aside.
2. In a separate bowl, beat the heavy cream to stiff peaks.
3. In thirds, gently fold the whipped cream into the peanut butter mixture until combined.
