- Total Time: 4 hours 20 minutes
- Course: Dessert
- Cuisine: American
- Difficulty: Easy
- Yield: 8 slices
- Calories: ~420 per slice (estimated)
Ingredients
For The Crust:
- 1 cup Fruity Pebbles cereal
- 1 cup Frosted Flakes
- 1 cup Nilla wafers (crushed)
- 1/4 cup granulated sugar
- 1/2 tsp salt
- 1/2 cup melted butter (unsalted)
For The Filling:
- 8 oz cream cheese (softened)
- 1/2 cup sour cream
- 1/2 cup powdered sugar
- 1 tsp vanilla extract
- 1 cup heavy whipping cream (cold)
- 1/2 cup Fruity Pebbles cereal (plus more for topping)
Ingredient Notes:
- Fruity Pebbles: You can use other colorful cereals like Trix or Fruit Loops, but Pebbles work best for texture.
- Nilla Wafers: Adds structure to the crust and balances the cereal sweetness.
- Cream Cheese: Full fat gives the best texture, but light cream cheese also works.
- Heavy Cream: Make sure it’s cold for easy whipping.
Instructions
Step 1: Make The Cereal Crust
In a mixing bowl, stir together the crushed Fruity Pebbles, Frosted Flakes, and Nilla wafers. Add sugar, salt, and melted butter. Stir until it feels like damp sand. Press the mixture into a 9-inch pie pan using the back of a spoon or your fingers. Make sure the crust is evenly packed. Pop it in the freezer while you make the filling.
Tip: Don’t skip freezing—it helps the crust firm up without baking.
Step 2: Whip The Cream
In a chilled bowl, whip the heavy cream until stiff peaks form. Set aside. This gives the pie that light, mousse-like texture.
Step 3: Make The Cheesecake Base
In another bowl, beat the softened cream cheese until smooth. Add the sour cream, powdered sugar, and vanilla extract. Mix until everything is creamy and lump-free.
Step 4: Combine And Fold
Gently fold the whipped cream into the cheesecake mixture. Once it’s smooth and fluffy, stir in 1/2 cup Fruity Pebbles cereal.
Step 5: Fill And Chill
Pour the filling into the chilled crust and smooth the top. Sprinkle extra Fruity Pebbles on top for color and crunch. Cover with plastic wrap and refrigerate for at least 4 hours, or overnight if you can wait that long.
Pairing & Serving Suggestions
- Pair it with: a cold glass of milk, hot coffee, or a fruity iced tea.
- Garnish with whipped cream or extra cereal right before serving for the full crunch effect.
- Serve cold, straight from the fridge.
Personal Tips For The Perfect Cereal Killer Pie
I remember the first time I made this pie—it was for a friend’s birthday brunch. I had leftover cereal boxes and cream cheese, and somehow, it all came together in this colorful mess of flavor that totally worked. Since then, I’ve played around with different cereals and add-ins.
Here’s what I’ve learned:
- Keep the crust packed tight: It can fall apart if it’s too loose.
- Chill long enough: Give the pie enough time to set. The filling firms up as it chills.
- Add the topping just before serving: Cereal can go soggy fast, so wait until you’re ready to slice.
- Try mixing cereals: Cocoa Pebbles with peanut butter drizzle is another wild version I’ve tried and loved!
FAQs About Cereal Killer Pie Recipe
Can I Make This Ahead Of Time?
Yes! In fact, it tastes even better after chilling overnight. Just keep it covered in the fridge.
What If I Don’t Have Fruity Pebbles?
You can swap in other cereals like Trix, Fruit Loops, or even Cinnamon Toast Crunch for a totally different flavor.
Can I Freeze The Pie?
You can, but I recommend freezing it without the cereal topping. Let it thaw in the fridge before serving.
Is This Pie Kid-Friendly?
Absolutely. Kids love the colors and flavors. It’s also a fun dessert to let them help make.
Can I Use Store-Bought Pie Crust?
You can, but it won’t have the same cereal crunch that makes this recipe special.
