About the Ingredients
Unsalted Butter
Unsalted butter adds rich flavor and helps bind the Rice Krispie base, ensuring it holds together well.
Mini Marshmallows
These are the classic element that gives the crust its chewy, gooey texture, melting perfectly to coat the cereal.
Rice Krispies Cereal
This cereal creates that nostalgic crunch while staying light and crisp, providing structure to the base and topping.
Heavy Cream
When whipped, it gives the filling a light, mousse-like texture, making the cheesecake airy and soft.
Full-Fat Cream Cheese
The base of the cheesecake filling; use full-fat for a smooth, creamy consistency that holds its shape well.
Confectioners’ Sugar
This sugar sweetens the filling without adding a grainy texture, dissolving seamlessly into the mixture.
Marshmallow Fluff
It adds sweetness and enhances the marshmallow flavor, creating a unified taste throughout the cheesecake.
Vanilla Extract
This extract brings warmth and depth to the creamy filling, rounding out the flavors with its aromatic notes.
Tips & Tricks
Butter Your Tools
A quick swipe of butter on your spatula and hands prevents the sticky marshmallow mixture from adhering to them, making the process smoother.
Press Firmly, Not Forcefully
The crust should be compact but not crushed, ensuring a stable base that holds together without being overly dense.
Use Cold Cream
Chilled heavy cream whips faster and holds its shape longer, giving the cheesecake its light, airy texture.
Pro Tips
- Soften the cream cheese fully to ensure a silky smooth filling without lumps.
- Let the cheesecake chill completely to allow the flavors to meld and the structure to firm up.
- For a neater slice, use a hot knife, wiping it clean between cuts for perfect presentation.
Step-by-Step Instructions
Melt the Marshmallows
In a large pot over medium-low heat, melt the butter completely. Add mini marshmallows and stir until smooth and glossy, about 4–5 minutes.
Prepare the Crust
Remove from heat and gently fold in Rice Krispies until evenly coated. Press two-thirds of the mixture into the bottom and 1 inch up the sides of a 9-inch springform pan. Reserve the rest for the topping. Let the crust cool completely.
Whip the Cream
In a chilled bowl, beat the heavy cream until stiff peaks form. Set aside.
Prepare the Filling
In another large bowl, beat cream cheese until smooth (about 2 minutes). Add confectioners’ sugar, Marshmallow Fluff, and vanilla extract. Beat again until creamy and lump-free.
Assemble the Cheesecake
Gently fold whipped cream into the cheesecake mixture until no white streaks remain. Pour into the prepared crust and spread evenly.
Add the Topping
Break the reserved Rice Krispie mixture into clusters and scatter over the cheesecake edges.
Chill Until Set
Refrigerate for at least 4 hours or overnight until fully set. Carefully release the springform pan before slicing.
Delicious Variations
Chocolate Drizzle
Drizzle melted chocolate over the top for an extra layer of flavor and a visually appealing finish.
Peanut Butter Twist
Mix in a swirl of creamy peanut butter into the cheesecake filling for a nutty variation.
Berry Burst
Add a layer of fresh berries between the crust and filling for a fruity contrast to the marshmallow sweetness.
How to Store Rice Krispie Treat Cheesecake
Refrigerator
Store covered in the fridge for up to 4 days to maintain freshness and texture.
Freezer
Wrap tightly in plastic wrap and freeze for up to 2 months. Thaw in the refrigerator overnight before serving.
Room Temperature
Avoid storing at room temperature as the cream cheese filling can soften too much and lose shape.
Reheating
This cheesecake is best served chilled, so no reheating is necessary. Simply slice and enjoy!
Frequently Asked Questions
Can I make this cheesecake ahead of time?
Yes! In fact, it’s best made the day before serving so it has plenty of time to set and develop flavor.
What if I don’t have a springform pan?
You can use a deep 9-inch pie dish or square baking pan lined with parchment paper for easy removal.
Can I use homemade marshmallows?
Absolutely — they’ll melt beautifully, though you may need to adjust the sweetness slightly.
How can I make it less sweet?
Reduce the Marshmallow Fluff to ½ cup or use slightly less confectioners’ sugar.
What is the best way to slice the cheesecake?
For clean slices, use a hot knife, wiping it clean between cuts to maintain a neat presentation.
