This Giant Rice Krispy Treat Cheesecake is the ultimate dessert for anyone who loves classic crispy rice cereal treats and rich, creamy cheesecake. It combines two nostalgic favorites into one impressive dessert that is perfect for birthdays, family gatherings, potlucks, holidays, celebrations, and weekend baking projects.

The outside layer is made with buttery marshmallows and crispy rice cereal, creating a chewy, crispy, and slightly gooey shell. Inside is a smooth and creamy cheesecake filling with a rich vanilla flavor. The contrast between the crunchy marshmallow cereal layer and the soft cheesecake center makes every bite incredibly satisfying.

Unlike a traditional baked cheesecake, this version can be made without turning on the oven for the cheesecake filling. The recipe is simple enough for beginners but impressive enough to become the centerpiece of a dessert table.

If you love Rice Krispie treats, no-bake cheesecake, marshmallow desserts, and easy homemade desserts, this giant cheesecake is a recipe worth saving.

Ingredients:

For the Giant Rice Krispy Treat Layer:

• 8 cups crispy rice cereal
• 6 cups mini marshmallows
• 5 tablespoons unsalted butter
• 1 teaspoon vanilla extract
• Pinch of salt

For the Creamy Cheesecake Filling:

• 24 ounces full-fat cream cheese, softened
• 1 cup powdered sugar
• 2 teaspoons vanilla extract
• 1 tablespoon fresh lemon juice
• 1 ½ cups heavy whipping cream, cold

Optional Toppings:

• Mini marshmallows
• Extra crispy rice cereal
• Melted white chocolate
• Melted milk chocolate
• Caramel sauce
• Chocolate chips
• Whipped cream
• Rainbow sprinkles
• Crushed Rice Krispie treats

Preparation:

Step 1: Prepare the Pan

Lightly grease a 9-inch springform pan with nonstick spray or softened butter. Line the bottom with parchment paper for easier removal.

Make sure the springform pan is securely closed before beginning because the Rice Krispy mixture will be pressed around the sides.

Step 2: Melt the Butter

Place the butter in a large saucepan over low heat. Allow it to melt completely without letting it brown.

Keeping the heat low helps prevent the butter and marshmallows from becoming too hot.

Step 3: Melt the Marshmallows

Add the mini marshmallows to the melted butter. Stir continuously with a lightly buttered spatula until the marshmallows are almost completely melted and smooth.

Remove the saucepan from the heat as soon as the mixture becomes creamy.

Step 4: Add Vanilla and Salt

Stir in the vanilla extract and a small pinch of salt. The vanilla adds flavor while the salt balances the sweetness of the marshmallows.

Step 5: Add the Crispy Rice Cereal

Immediately add the crispy rice cereal to the warm marshmallow mixture.

Fold gently until the cereal is completely coated. Work quickly because the mixture becomes harder to spread as it cools.

Step 6: Form the Giant Rice Krispy Shell

While the cereal mixture is still warm, transfer it into the prepared springform pan.

Using lightly buttered hands or a buttered spatula, press the mixture firmly across the bottom and up the sides of the pan.

Create an even layer around the entire pan while leaving a large cavity in the center for the cheesecake filling.

Step 7: Shape the Edges

Press the Rice Krispy mixture firmly around the sides so the cheesecake shell holds its shape.

Try to keep the walls approximately the same thickness throughout. Avoid making the shell extremely thin because it needs enough structure to hold the creamy filling.

Set aside to cool and firm up.

Step 8: Prepare the Cream Cheese

Place the softened cream cheese in a large mixing bowl.

Beat until smooth and creamy with no large lumps remaining.

Softened cream cheese is important because cold cream cheese can create a lumpy cheesecake filling.

Step 9: Add Powdered Sugar and Flavorings

Add the powdered sugar, vanilla extract, and fresh lemon juice.

Beat again until the mixture becomes smooth, creamy, and well combined.

The lemon juice adds a subtle brightness without making the cheesecake taste strongly lemony.

Step 10: Whip the Heavy Cream

In a separate bowl, beat the cold heavy whipping cream until stiff peaks form.

Do not overbeat the cream. Stop once it becomes thick enough to hold its shape.

Step 11: Combine the Cheesecake Filling

Gently fold the whipped cream into the cream cheese mixture.

Fold slowly rather than mixing aggressively. This helps maintain the light and fluffy texture of the cheesecake filling.

Step 12: Fill the Rice Krispy Shell

Spoon the cheesecake filling into the cooled Rice Krispy shell.

Spread the filling evenly from the center toward the edges. Smooth the top with a spatula.

Step 13: Chill the Cheesecake

Cover the cheesecake loosely and refrigerate for at least 6 hours, preferably overnight.

The chilling time allows the cheesecake filling to firm up and gives the Rice Krispy shell time to fully set.

Step 14: Remove From the Pan

Once completely chilled, carefully release the springform pan.

Run a thin knife around the edge if necessary before opening the pan.

Transfer the cheesecake to a serving plate.

Step 15: Add the Toppings

Decorate the top with whipped cream, mini marshmallows, extra crispy rice cereal, chocolate drizzle, caramel sauce, or colorful sprinkles.

For a dramatic presentation, add a few small pieces of Rice Krispy treats around the top of the cheesecake.

Step 16: Slice and Serve

Use a sharp knife to cut the cheesecake into slices.

For cleaner slices, warm the knife under hot water, dry it completely, then slice. Wipe the knife between cuts.

Serve chilled and enjoy the combination of creamy cheesecake and chewy crispy cereal.

Variations:

Chocolate Rice Krispy Treat Cheesecake

Add ½ cup unsweetened cocoa powder to the cheesecake filling and use chocolate crispy cereal for the outer layer if available.

Peanut Butter Rice Krispy Cheesecake

Add ½ cup creamy peanut butter to the cheesecake filling. Drizzle the finished cheesecake with melted peanut butter and chocolate.

Chocolate Chip Version

Fold ½ cup mini chocolate chips into the cheesecake filling before adding it to the Rice Krispy shell.

Strawberry Cheesecake

Add chopped fresh strawberries or a layer of strawberry sauce over the cheesecake filling. Finish with whipped cream and fresh strawberries.

Birthday Cake Version

Add colorful sprinkles to the cheesecake filling and decorate the top with extra sprinkles and mini marshmallows.

Caramel Version

Drizzle caramel sauce over each slice before serving. Add chopped toasted pecans for extra crunch.

S’mores Version

Add mini chocolate chips and crushed graham crackers to the cheesecake filling. Top with marshmallows and melted chocolate.

COOKING Note :

The most important part of this recipe is working quickly when forming the Giant Rice Krispy Treat Cheesecake shell. The marshmallow mixture becomes sticky and firm as it cools.

Lightly butter your hands or spatula before pressing the cereal mixture into the pan. This makes shaping the crust much easier.

Do not press the Rice Krispy mixture too aggressively. It should be firm enough to hold together but still slightly soft and chewy.

Make sure the cream cheese is fully softened before preparing the filling. This creates a smoother cheesecake texture.

For the best results, refrigerate the cheesecake overnight before slicing. The longer chilling time gives the filling a firmer consistency and makes slicing easier.

Serving Suggestions :

Serve this Giant Rice Krispy Treat Cheesecake chilled as a centerpiece dessert.

It pairs especially well with:

• Fresh strawberries
• Raspberries
• Blueberries

For parties, cut the cheesecake into smaller wedges because the dessert is rich and filling.

How long does Rice Krispy Treat Cheesecake last?

Store it covered in the refrigerator and enjoy it within about 3–4 days for the best texture and flavor.

Can I freeze this cheesecake?

The cheesecake filling can be frozen, but the Rice Krispy layer may become softer after thawing. For the best texture, refrigeration is recommended.

Why is my Rice Krispy mixture too hard?

The marshmallow mixture may have been heated too long or pressed too firmly into the pan. Use low heat and avoid overcooking the marshmallows.

What size pan should I use?

A 9-inch springform pan works well for creating a tall, dramatic cheesecake. A slightly larger pan will produce a wider and shorter dessert.

Lightly grease the pan and line the bottom with parchment paper. You can also lightly butter the sides before pressing in the Rice Krispy mixture.

Can I make individual Rice Krispy cheesecakes?

Yes. Press the Rice Krispy mixture into small individual molds or muffin cups, leaving the center open for cheesecake filling. Chill until firm before serving.
