⭐ Ingredients

Angel Food Layer (Heaven)

1 box angel food cake mix
Water as directed on box

Devil’s Food Layer (Hell)

1 box devil’s food cake mix
Ingredients as directed on box

Peanut Butter Mousse Filling

1 ½ cups heavy whipping cream
1 cup creamy peanut butter
8 oz cream cheese, softened
1 cup powdered sugar
1 tsp vanilla extract

Chocolate Ganache Topping

1 ½ cups semi-sweet chocolate chips
1 cup heavy cream
2 tbsp butter (optional for shine)

🍽️ Instructions

1️⃣ Bake the Cakes

Prepare angel food cake in a 9×13 pan according to package directions. Let cool completely.
Prepare devil’s food cake in another 9×13 pan. Let cool completely.

Tip: For best results, bake these the day before and chill the cakes so they are easier to layer.

2️⃣ Make the Peanut Butter Mousse

Beat the cream cheese and peanut butter until smooth.
Mix in powdered sugar and vanilla.
In a separate bowl, whip the heavy cream until stiff peaks form.
Fold whipped cream into the peanut butter mixture until fluffy.

Refrigerate until ready to assemble.

3️⃣ Assemble the Cake

Place the angel food cake layer on the bottom of a clean 9×13 dish (trim edges if needed).
Spread the entire batch of peanut butter mousse evenly over the top.
Place the devil’s food cake layer on top and lightly press down.
Chill while you prepare the ganache.

4️⃣ Make the Ganache

Heat the heavy cream just until it begins to simmer.
Pour over chocolate chips in a bowl.
Let sit 1 minute, then whisk until smooth.
Add butter if you want extra shine.
Let cool slightly until thickened but still pourable.

5️⃣ Finish the Cake

Pour ganache over the top layer, spreading evenly.
Refrigerate at least 4 hours (overnight is best).

🎉 Serve

Slice into squares and serve chilled.
Every bite is ultra-creamy, chocolatey, rich, and absolutely dangerous in the best way.

🔄 Variations

Salted peanut butter mousse: Add a pinch of flaky sea salt.
Reese’s version: Add chopped Reese’s cups between layers.
Mocha twist: Add 1 tsp espresso powder to the ganache.
Sheet-style layering: You can also freeze briefly for cleaner cuts.

If you want, I can give you a from-scratch version (no cake mixes), a smaller 8×8 version, or a no-bake heaven & hell dessert!
