Instructions
Prep the crust: Grease a 9-inch springform pan. In a medium saucepan over low heat, add the unsalted butter and allow it to melt slowly. Stir frequently so it doesn’t brown.
Add marshmallow fluff to the melted butter and stir continuously until the mixture is smooth and evenly combined. Remove the pan from heat as soon as it’s smooth.
Mix in the Rice Krispies cereal, folding gently until every piece is well-coated in the marshmallow-butter mixture.
Firmly press the coated Rice Krispies into the bottom of the prepared 9-inch springform pan to form an even crust layer. Use the back of a measuring cup for a compact finish. Set aside to cool slightly.
Make the cheesecake filling: In a large bowl, beat the softened cream cheese until creamy and free of lumps. Add the granulated sugar and vanilla extract and continue to beat until smooth.
Add the eggs one at a time, beating on low speed and ensuring each is incorporated before adding the next. Do not overmix — stop when the filling is smooth.
Gently fold in the sour cream with a spatula until just combined. This keeps the filling silky and prevents overbeating.
Pour the cheesecake filling over the prepared Rice Krispies crust, smoothing the top with an offset spatula to create an even layer.
Bake: Preheat your oven to 325°F (165°C). Place the springform pan on a middle rack and bake for 45–50 minutes, or until the edges are set and the center is slightly jiggly but not liquid.
Turn off the oven and crack the oven door open. Let the cheesecake cool in the oven for about one hour to minimize cracking.
Add toppings: Once cooled to room temperature, sprinkle mini marshmallows and the extra 1/2 cup Rice Krispies over the top. Drizzle with the 1/4 cup melted chocolate in a decorative pattern.
Chill: Refrigerate the cheesecake for at least 4 hours or ideally overnight to allow it to set fully before serving.
Notes
Store the cheesecake covered in the refrigerator for up to 4 days. You can freeze the cheesecake (without the crispy topping) for up to 1 month.
