This Brownie Banana Funtastico is a layered dessert with warm brownies, banana mousse, whipped cream, and chocolate syrup — basically a banana split sundae but with extra drama. It’s quick to put together, uses mostly store-bought stuff, and hits that late-night sweet craving hard.

Why I Like This Recipe
Honestly, I wasn’t aiming for a sundae. I just had brownies, bananas, and zero patience for anything complicated. But stacking it all into one bowl? Instant upgrade. No rules — just sweet, messy comfort.
Ingredients
Brownie Base
- 1 box (16.3 oz) brownie mix
- Whatever the box calls for (usually eggs, oil, water)
Banana Mousse
- 1 envelope Dream Whip
- 1½ cups milk (divided)
- 1 banana pudding mix (4-serving size)
Toppings
- ½ cup pineapple topping
- 8 bananas
- 1 cup whipped cream
- ½ cup chocolate syrup
- ½ cup chopped nuts
- ½ cup maraschino cherries
How To Make Brownie Banana Funtastico
- Bake the brownies: Make the brownie mix per the box instructions. Let it cool a bit before layering.
- Whip the topping: Beat Dream Whip with ½ cup milk until fluffy. Takes about 5 mins. Set aside.
- Make the mousse: In the same bowl, mix banana pudding with 1 cup milk. Fold in the whipped topping until smooth.
- Start layering: Drop a warm brownie in a bowl. Spoon on pineapple topping. Split a banana and lay both halves on the sides.
- Top it all: Add banana mousse, whipped cream, chocolate syrup, nuts, and a cherry. Or two. No rules.

Tips for Success
- Let brownies cool slightly so the mousse doesn’t melt
- Use ripe bananas — softer = better texture
- Want more flavor? Add cinnamon to the mousse
- Pineapple too much? Caramel works as a swap
- Chill mousse if you want cleaner layers
Storage and Reheating
- Fridge: Store assembled bowls covered, up to 3 days. They’ll get softer but still good.
- Freezer: Not ideal — mousse texture gets weird.
- Reheat: Don’t. Just eat cold or room temp. Still hits.
Frequently Asked Questions
- Can I make the mousse ahead?
Yep. Chill it until ready to use. Gets thicker too. - Do I have to use Dream Whip?
You can sub with any whipped topping, but Dream Whip holds structure best. - What if I don’t like pineapple?
Skip it or swap with something you like — strawberry sauce, Nutella, caramel. - Can I use homemade brownies?
Absolutely. Just aim for fudgy not cakey. - Is this like a banana split?
Kinda. But layered and less formal. Feels homemade in the best way.
Common Mistakes and How to Dodge Them
- Too-hot brownies: If they’re still super warm, the mousse will slide right off. Let them cool a bit.
- Overmixing mousse: Once the whipped topping goes in, fold gently. Don’t deflate it.
- Not using ripe bananas: Underripe ones are too firm and bland. You want soft and spotty.
- Skipping the nuts or syrup: You don’t have to use both, but some kind of topping gives it texture.
- Thinking it has to be perfect: It’s a sundae. Messy is part of the vibe.
