Ingredients
- 1 package of fudge brownie mix (for rich chocolate flavor)
- 2 eggs (for structure)
- 1/4 cup of oil (adds moisture)
- 1/4 cup of water (helps combine ingredients)
- 4 cups of cold milk (for pudding consistency)
- 2 packages of instant vanilla pudding mix (thickening agent)
- 1 cup of creamy peanut butter (adds a nutty flavor and creaminess)
- 4 teaspoons of vanilla extract (enhances flavor)

How to Make Peanut Butter Cup Brownie Trifle
Step 1. Begin by preparing the fudge brownie mix according to the package instructions. This typically involves combining the brownie mix with the eggs, oil, and water in a mixing bowl. Whisk everything together until the mixture is well combined and smooth. Pour the batter into a greased 9×13-inch baking dish, spreading it evenly. Watch for the color change and texture—after baking, it should be set but still moist in the center.
Step 2. Once the brownies are baked, allow them to cool completely in the baking dish. This cooling process helps set the brownies, making them easier to cut into squares later. You’ll know they are ready to layer when they are firm to the touch but still slightly soft and fudgy.
Step 3. While the brownies cool, prepare the instant vanilla pudding. In a large bowl, combine the cold milk and instant pudding mix. Use a whisk to combine thoroughly until the mixture thickens up, which usually takes just a couple of minutes. The pudding should have a smooth, creamy consistency, ready for layering.
Step 4. In a separate bowl, combine the creamy peanut butter and vanilla extract. Mix these ingredients until they are smooth and well incorporated. The peanut butter will add a nutty richness that balances perfectly with the sweet flavors of the pudding and brownies.
Step 5. Gently fold in the Cool Whip into the peanut butter mixture. This lightens the mixture and gives it a fluffy texture that will work well with the other layers. Once combined, the blend should be airy and smooth, ready to enhance the trifle experience.
Step 6. Now, it’s time to begin layering the trifle. Start with a layer of cooled brownie squares at the bottom of your trifle dish. The brownies should be cut into small pieces to create an even base. This first layer will add a rich, chocolatey foundation for the dessert.
Step 7. Next, spoon a layer of the creamy peanut butter Cool Whip mixture over the brownies, spreading it evenly. This will add a delightful creaminess on top of the brownie layer, enriching the flavor and offering a nice contrast in textures.
Step 8. Follow up with a layer of the vanilla pudding, spreading it gently over the peanut butter layer. This layer should be smooth and even, allowing the flavors to meld together. It will provide a nice contrast to the denser layers below.
Step 9. Continue the layering process with more brownie, then another layer of the peanut butter mixture, and then the vanilla pudding again. Repeat until you have used all your ingredients, finishing with a layer of the pudding for a polished look.
Step 10. Finally, top the trifle with the remaining Cool Whip. Use a spatula to spread it evenly, making it look neat and inviting. Decorate with the halved Reese’s cups, strategically placing them on top for an appealing finish. The trifle is now ready for serving, showcasing its layers beautifully.

Pro Tips for Best Results
- Ensure the brownies are completely cooled before layering to prevent melting the other ingredients.
- Use a trifle dish for a beautiful presentation to show off the layers.
- If you want to enhance the flavor, consider adding a sprinkle of sea salt on top.
- For a fun twist, try drizzling some chocolate sauce over the layers.
- If you have extra peanut butter mixture, serve it alongside for those who want a little more.
- Store leftovers in the refrigerator with a loose cover to maintain freshness.
Common Mistakes to Avoid
Not cooling the brownies completely: This can lead to a messy trifle, as warm brownies may melt the cream layers. Always allow them to cool fully before assembling.
Not whisking the pudding enough: An under-whisked pudding can be lumpy, which affects the texture of your trifle. Make sure it’s thoroughly mixed and smooth.
Overmixing the whipped topping: When combining it with the peanut butter, overmixing can deflate the mixture, leading to a denser result. Mix gently to keep the texture light.
Using too much milk for the pudding: If you don’t measure accurately, the pudding may not set properly. Stick to the package instructions for best results.
Layering too densely: If you pack the layers too tight, your trifle may turn out too heavy. Aim for even layers to maintain a nice balance in each bite.
Cutting the brownies too large: Large brownie pieces can disrupt the layering. Smaller cubes will help create a better structure and allow for easier serving.
Variations & Substitutions
For a different twist, you can replace the creamy peanut butter with crunchy peanut butter for added texture. Consider adding a layer of banana slices or a drizzle of caramel sauce for a sweet contrast. You could also use chocolate pudding instead of vanilla for a richer flavor profile or substitute the Cool Whip with homemade whipped cream for a more personal touch.
Storage & Reheating
For room-temperature storage, keep the trifle covered to prevent drying out. If you plan on refrigerating leftovers, place it in the fridge, where it can last for about 3 to 4 days. If you wish to freeze the trifle, it’s best to store individual portions in airtight containers. When reheating, serve it chilled rather than trying to warm it, as the texture may be compromised.
