Ingredients
For the Crust:
-
½ cup (1 stick) unsalted butter
-
1 (10 oz) bag mini marshmallows
-
8 cups Rice Krispies cereal
For the Filling:
-
1 cup heavy cream, chilled
-
16 oz (2 blocks) full-fat cream cheese, softened
-
½ cup confectioners’ sugar
-
¾ cup Marshmallow Fluff
-
1 teaspoon pure vanilla extract
Optional Garnishes:
-
Whipped cream or Cool Whip
-
Drizzled white or milk chocolate
-
Mini marshmallows or Rice Krispies clusters
Step-by-Step Instructions
Step 1: Prepare the Crust
-
Melt the butter and marshmallows:
In a large saucepan over medium heat, melt the butter. Add the marshmallows and stir constantly until completely melted and smooth. This should take about 5–7 minutes. Make sure there are no lumps of unmelted marshmallow. -
Combine with cereal:
Remove from heat and quickly stir in the Rice Krispies cereal. Mix until all the cereal is evenly coated in the sticky, glossy marshmallow mixture. -
Reserve some for topping:
Scoop out about 3 cups of this mixture and set aside for decoration later. -
Form the crust:
Press the remaining Rice Krispies mixture firmly into the bottom and slightly up the sides of a 9-inch springform pan. Use a piece of parchment paper or lightly buttered spatula to press evenly.
Tip: Don’t press too hard — you want the crust firm but not rock-solid. -
Chill the crust:
Place the pan in the refrigerator to set while you prepare the cheesecake filling.
Step 2: Make the Cheesecake Filling
-
Whip the cream:
In a cold mixing bowl, whip the chilled heavy cream with a hand mixer on medium-high speed until stiff peaks form. This step is crucial for creating a light and airy filling. Once whipped, set the bowl aside in the refrigerator to keep it cold. -
Beat the cream cheese:
In a separate large mixing bowl, beat the softened cream cheese and confectioners’ sugar together until the mixture is creamy and smooth, with no lumps. Scrape down the sides of the bowl to ensure everything is evenly mixed. -
Add Marshmallow Fluff and vanilla:
Mix in the Marshmallow Fluff and vanilla extract until the filling becomes silky and uniform. The fluff adds sweetness and gives the cheesecake that nostalgic marshmallow flavor. -
Fold in whipped cream:
Using a spatula, gently fold the whipped cream into the cream cheese mixture. Avoid overmixing — you want to keep as much air in the mixture as possible for a light, mousse-like texture. Continue folding just until no white streaks remain.
Step 3: Assemble the Cheesecake
-
Add the filling:
Pour the marshmallow cheesecake filling into the prepared Rice Krispie crust. Spread it evenly with an offset spatula or the back of a spoon. Smooth out the top so it’s level. -
Prepare the topping:
Take the 3 cups of Rice Krispies mixture you reserved earlier and press it gently onto a piece of parchment paper or into a loaf pan. Chill for 15 minutes to firm it up. Once set, cut into small squares or break into rustic clusters. -
Decorate the top:
Arrange the Rice Krispie clusters on top of the cheesecake before serving. You can mound them in the center or scatter them around the edges for a fun, playful look.
Step 4: Chill and Set
Refrigerate the cheesecake for at least 4 hours — overnight is even better. The chilling time allows the filling to set properly and the flavors to meld together beautifully.
When ready to serve, release the cheesecake from the springform pan by running a knife around the edge and gently removing the outer ring. Slice with a clean, sharp knife, wiping between cuts for neat slices.
Tips for Success
-
Use full-fat cream cheese – it gives the best flavor and texture for no-bake cheesecakes.
-
Whip the cream well – soft peaks won’t hold up; aim for stiff peaks for the perfect consistency.
-
Press the crust gently – too much pressure will make it hard to cut later.
-
Chill thoroughly – the longer the cheesecake chills, the firmer and creamier it becomes.
-
Use parchment paper – lining the bottom of your springform pan makes it easy to transfer the finished cheesecake to a serving plate.
-
Try flavor variations – you can add melted chocolate, peanut butter, or caramel to the crust for a unique twist.
Flavor Variations
-
Chocolate Rice Krispie Cheesecake: Replace half of the cereal with Cocoa Krispies and add a drizzle of chocolate ganache on top.
-
Peanut Butter Marshmallow: Add ¼ cup melted peanut butter to the marshmallow mixture before mixing with cereal.
-
Strawberry Dream: Fold diced fresh strawberries or strawberry jam into the cheesecake filling.
-
Cookies & Cream: Mix crushed Oreos into the filling for an extra layer of texture.
-
Caramel Crunch: Drizzle salted caramel over the cheesecake and top with toffee bits.
Serving Ideas
-
Serve each slice with a drizzle of chocolate syrup or caramel sauce for an extra indulgent touch.
-
Add a dollop of whipped cream on top with a few extra Rice Krispies sprinkled for crunch.
-
For a festive presentation, top with mini marshmallows and edible glitter.
Storage Instructions
-
Refrigerator: Store leftovers in an airtight container for up to 4 days.
-
Freezer: You can freeze the cheesecake (without topping) for up to 1 month. Wrap tightly in plastic wrap and foil. Thaw in the fridge overnight before serving.
-
Make-Ahead: The crust and filling can be made a day in advance. Assemble the cheesecake the next day for a perfectly fresh dessert.
