Essential Ingredients
Cereal Base:
- ¼ cup butter
- 4 cups mini marshmallows
- 4 cups Lucky Charms cereal
Cheesecake:
- 16 ounces cream cheese, room temperature
- 2 teaspoons lemon juice
- 2 cups heavy whipping cream
- ⅓ cup granulated sugar
- Green food coloring, to taste
Toppings:
- Lucky Charms cereal marshmallows
- Sprinkles
Preparation Steps
- Prepare the Base: Line a 9×9-inch square pan with parchment paper. In a large saucepan over low heat, melt the butter. Add mini marshmallows and stir until completely melted and blended. Cook for two minutes, stirring constantly, then remove from heat. Add Lucky Charms cereal and stir until well coated.
- Set the Base: Pour the mixture into the prepared pan and spread evenly, packing it firmly with a spatula or hands. Let the base cool completely.
- Make the Cheesecake Layer: In a mixing bowl, beat together the softened cream cheese and lemon juice until smooth. Using an electric mixer, beat in the heavy whipping cream until thick. Add sugar and continue beating until stiff peaks form. Add green food coloring to achieve the desired color.
- Assemble and Freeze: Pour the cheesecake mixture over the cooled cereal base and spread evenly. Freeze for at least 4 hours or ideally overnight.
- Add Toppings: Just before serving, separate the marshmallows from the remaining Lucky Charms cereal and sprinkle them on top, along with any additional sprinkles. Cut into squares and serve chilled.

Health Benefits
While this dessert is undeniably indulgent, it does contain calcium and protein from the cream cheese and heavy cream. The cereal base adds some whole grain, though it’s best enjoyed as an occasional treat.
Serving Suggestions
Serve these cheesecake bars chilled to maintain their shape and creamy texture. Pair with a cup of hot coffee or a chilled glass of milk for a balanced contrast. They make a great addition to dessert buffets or party platters.
Creative Variations
- Fruit Twist: Add a layer of fresh sliced strawberries or blueberries between the base and the cheesecake layer.
- Chocolate Lovers: Drizzle melted chocolate on top or add chocolate chips to the cheesecake mixture.
- Festive Touch: Use different food coloring for themed events, like red for Valentine’s Day or pastel colors for Easter.
- Nutty Crunch: Mix crushed nuts into the cereal base for extra texture.
Storage Tips
Store leftover cheesecake bars in an airtight container in the refrigerator for up to 3 days. For longer storage, keep them in the freezer for up to 2 weeks. Thaw in the fridge before serving.
Pro Tips
- Make sure the cereal base is completely cooled before adding the cheesecake layer to prevent melting.
- Use room-temperature cream cheese for a smoother, lump-free filling.
- Freeze overnight for the best texture and ease of cutting.
Frequently Asked Questions

How do I make the bars easier to cut? Dip your knife in hot water and wipe it dry between cuts for clean slices.
