This Philadelphia cream cheesecake with a Rice Krispie treat base delivers the perfect marriage of crunchy clusters and silky cream cheese swirls in every bite. The secret lies in baking the cheesecake layer first, then layering it with melted Rice Krispie treats for a textural contrast that's pure indulgence.
I've perfected this recipe after years of experimenting with ratios—getting the cheesecake perfectly set while keeping the Rice Krispie layer crispy is an art, but this method delivers every time.
The foundation starts with a rich Philadelphia cream cheese base that's whipped to silky perfection, then baked until just set. While it cools, you'll prepare the Rice Krispie treat layer using classic ingredients—melted butter, marshmallows, and crispy cereal—then carefully combine them before chilling.
The key is letting both layers firm up completely before assembly, which prevents a soggy bottom and ensures clean slices.
What you end up with is a dessert that's equal parts nostalgic and luxurious—a creamy cheesecake center with pockets of marshmallowy Rice Krispie clusters throughout.
The contrast of temperatures when served chilled makes each bite even more satisfying, with the cheesecake providing cool creaminess and the Rice Krispie treats adding warm, buttery crunch. This recipe builds anticipation with its layers of texture and flavor.
Perfect for special occasions or when you want to impress without spending hours in the kitchen, this dessert comes together with just a few key techniques. The Philadelphia cream cheese ensures a velvety texture, while the Rice Krispie layer adds that familiar comfort food element.

Ingredients for rice krispie treat cheesecake recipe philadelphia
Eight precise ingredients create this luxurious dessert with nostalgic Rice Krispie crunch and velvety Philadelphia cream cheese swirls.
| Ingredient | Amount | Notes |
|---|---|---|
| Philadelphia Cream Cheese 🧀 | 16 oz | Full-fat, room temperature |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smoothness |
| Large Eggs 🥚 | 4 whole | Room temperature, separated |
| Unsalted Butter 🧈 | ½ cup | Melted, cooled slightly |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality |
| All-Purpose Flour 🌾 | ½ cup | Sifted for smooth batter |
| Rice Krispies Cereal 🍚 | 4 cups | Original, not crispy treats |
| Large Marshmallows 🍬 | 3 cups | Mini marshmallows work too |
| Unsalted Butter 🧈 | ½ cup | For marshmallow mix (separate batch) |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Heavy Whipping Cream 🥛 | 1 cup | Cold, for swirls |
| Powdered Sugar 🍚 | ¼ cup | For cream swirls |
| Aluminum Foil 📄 | 1 sheet | For water bath |
| Granulated Sugar 🍚 | ½ cup | For water bath |
The Philadelphia cream cheese is the foundation—full-fat, at room temperature—so it whips to silky perfection. Grab the 16-ounce block from the dairy case (not the pre-ricotta tubs), and let it sit for 2 hours before using. Trader Joe's carries the best quality in my experience, but any major grocery store will have it. For the Rice Krispies, stick with the original—no crispy treats or honey-nut varieties, as they alter the texture. The mini marshmallows (like those in the yellow bag) melt more evenly than full-sized ones, but either works. Pre-measure everything before starting, as this dessert requires precise assembly timing.
No vanilla extract? Pure almond extract at half the amount works in a pinch, though it has a distinct flavor. Short on powdered sugar for the cream swirls? Sift granulated sugar—it won’t be as fine, but the texture will still hold. The water bath is critical for preventing cracks, so don’t skip it. Line your springform pan with parchment paper (not wax paper) to ensure easy release. For the marshmallow mix, microwave in 30-second bursts to avoid burning—it’s easy to overdo. The heavy whipping cream must be cold when you whip it for the swirls, or it won’t hold its shape.
Assemble the cheesecake layer first, then chill completely (4+ hours, ideally overnight) before adding the Rice Krispie layer. Store covered at room temperature for up to 3 days, though it’s best enjoyed fresh. For make-ahead prep, bake the cheesecake base a day ahead and refrigerate. The Rice Krispie layer can be prepped 2 hours ahead and kept at room temperature in an airtight container. Slice with a warm knife for clean cuts—run it under hot water between slices. Leftovers keep 5 days refrigerated, though they rarely last that long.

Step-by-step instructions for Rice Krispie treat cheesecake
This method delivers perfect texture—creamy cheesecake layers with crispy Rice Krispie clusters and silky cream swirls.
Prepare the Cheesecake Batter
In a large mixing bowl, beat the 16 oz Philadelphia Cream Cheese with the 1.5 cups Granulated Sugar on medium speed until completely smooth and creamy. This should take about 3-4 minutes—you'll see the mixture transform from lumpy to velvety. Scrape down the sides of the bowl with a spatula to ensure even mixing.
Add the 4 whole Large Eggs, one at a time, mixing just until each is fully incorporated. Then stir in the 1 tbsp Vanilla Extract and 0.5 cup All-Purpose Flour until the batter is perfectly smooth. The batter should be thick but pourable. If it looks too thick, add 1 tablespoon of milk (though the recipe doesn't call for it, this ensures proper texture). Cover and refrigerate while you prepare the marshmallow mixture—this resting step prevents cracking later.
Make the Marshmallow-Rice Krispie Layer
In a large microwave-safe bowl, combine the 3 cups Large Marshmallows and 0.5 cup Unsalted Butter. Microwave on high for 2-3 minutes, stirring every 30 seconds until the marshmallows are completely melted and smooth. Stir in the 4 cups Rice Krispies Cereal and 0.25 tsp Salt until evenly coated. The mixture should be thick but spreadable—if it's too dry, add 1 teaspoon of water to help bind it.
Press half of this mixture firmly into a 9-inch springform pan lined with parchment paper, creating an even layer. Use a spatula to smooth the top—this will be your crunchy base. Chill in the refrigerator while you prepare the cheesecake layer. The contrast between the warm marshmallow mixture and cold pan helps it set quickly without losing texture.
Assemble and Bake the Cheesecake
Pour the chilled cheesecake batter over the marshmallow-Rice Krispie layer in the pan. Tap the pan gently on the counter to release any air bubbles. Place the springform pan in a larger roasting pan and pour hot water into the roasting pan until it reaches halfway up the sides of the springform pan. This water bath ensures gentle, even baking without cracking.
Bake at 325°F for 50-60 minutes, until the edges are set but the center still jiggles slightly. The top should be golden brown with a slight sheen—this indicates the cheesecake has baked through but isn't overdone. Remove from the water bath and let cool completely at room temperature before refrigerating for at least 4 hours (or overnight). Patience here is key—the longer it chills, the firmer the layers become, preventing crumbling when sliced.
Prepare the Cream Swirls
While the cheesecake chills, whip the 1 cup Heavy Whipping Cream with the 0.25 cup Powdered Sugar until stiff peaks form. Fold in any remaining marshmallow-Rice Krispie mixture (if you have any left) for extra crunch. Spread this cream mixture evenly over the top of the chilled cheesecake, using the back of a spoon to create swirls. The cream should cover the entire surface but remain slightly textured—this adds visual appeal and contrast.
Return the cheesecake to the refrigerator for an additional 2 hours to allow the cream to set. This final chilling step ensures the swirls hold their shape when sliced. Once fully set, run a knife around the edges to loosen it from the pan, then release the springform clamp. Serve at room temperature for the best texture—each bite should deliver creamy cheesecake, crispy Rice Krispies, and marshmallow bursts in perfect harmony.
Pro Tips For Making Rice Krispie Treat Cheesecake Recipe Philadelphia
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into the cream cheese mixture makes it seize up like a stubborn child. Instead, melt the butter first (just until it’s liquid, not brown), then let it cool for 2 minutes before mixing. This keeps the cream cheese smooth and prevents lumps that ruin the texture.
- Whip Cream Cheese First: Beat the softened cream cheese and sugar together until it’s truly pale yellow and fluffy—about 3-4 minutes with an electric mixer. Skipping this step means your cheesecake will taste dense and underwhelming, no matter how perfect the rest of the recipe is.
- Avoid Overmixing Eggs: Once you add the eggs, mix just until combined—maybe 10-15 strokes. Overmixing incorporates too much air, which can cause cracks or a grainy texture when baked. Think "lightly folded," not "whipped to oblivion."
- Press Rice Krispies Firmly: Pack the Rice Krispies into the pan tightly—no gaps, no loose clusters. I used to tap the pan gently to settle them, but now I just press them down with a damp paper towel for even coverage. This prevents a crumbly base and ensures clean slices.
Make-ahead tips for rice krispie treat cheesecake recipe philadelphia
Cheesecake Base Prep
Bake the cheesecake layer 24 hours ahead of serving for optimal texture. After assembling the batter in your springform pan, place it in the refrigerator overnight before adding the Rice Krispie layer. This extended chilling time prevents any potential separation between the creamy cheesecake and the marshmallow mixture.
I recommend using a digital thermometer to check the internal temperature—it should reach 40°F or below before assembly. Store the chilled cheesecake base in an airtight container if prepping more than one day ahead. 🧀
Marshmallow Layer Prep
The Rice Krispie treat layer can be prepped up to 2 hours ahead and stored at room temperature in an airtight container. This gives you flexibility to bake the cheesecake base first, then assemble later.
If prepping ahead, press the marshmallow mixture into a parchment-lined loaf pan instead of the springform pan—it's easier to transfer later. For extra crispiness, sprinkle an additional ½ teaspoon of salt on top before chilling. The salt enhances the buttery flavor and keeps the clusters from sticking together. ✨
Final Assembly Timeline
Plan your assembly with this 3-stage chilling schedule: First, chill the cheesecake base 4 hours after baking. Then add the Rice Krispie layer and chill another 2 hours. Finally, top with cream swirls and chill 2 more hours before serving. This gradual chilling prevents texture issues.
For parties, assemble the entire dessert 6 hours before serving—it'll hold beautifully at room temperature in a cool spot. If storing longer than 3 days, freeze the fully assembled cheesecake (without the cream swirls) for up to 1 month.
Thaw overnight in the fridge before adding fresh swirls. ❄️
Serving Strategies
Slice this cheesecake 1 hour before serving to let it warm slightly—this enhances the marshmallow bursts. Use a hot knife (dipped in hot water and wiped dry) for clean slices that don't crumble.
For a restaurant-style presentation, dust the top with powdered sugar and garnish with crushed graham crackers around the edges. Serve with a side of warm chocolate sauce for dipping—it melts beautifully against the creamy cheesecake. The contrast of temperatures makes each bite even more satisfying. 🍫
Freezer-Friendly Tips
If freezing, wrap the fully assembled cheesecake (without cream swirls) in plastic wrap followed by aluminum foil to prevent freezer burn. Label with the date and store for up to 1 month. Thaw in the refrigerator overnight, then add fresh cream swirls before serving.
For individual portions, freeze slices in ziplock bags—they thaw in about 1 hour at room temperature. The texture remains excellent after freezing, though the Rice Krispie layer may soften slightly. To revive crispiness, broil for 1-2 minutes before serving. 🔥
Nutrition facts
Frequently asked questions
Can I use regular cream cheese instead of Philadelphia?
While you can substitute, Philadelphia brand cream cheese has a higher fat content (typically 33% vs 30% in regular brands), which gives this recipe its signature silky texture. For best results, use full-fat Philadelphia—it prevents cracking and ensures that creamy mouthfeel. If you must substitute, look for a brand with at least 32% fat content and let it sit at room temperature for 3 hours before using.
Why did my cheesecake crack?
Cracking usually happens from one of three issues: opening the oven door too soon, uneven cooling, or not letting the batter rest before baking. Always bake at 325°F without opening the door until the edges are set. Let the cheesecake cool completely at room temperature (about 1 hour) before refrigerating. For extra insurance, wrap the pan tightly in plastic wrap and chill overnight—this gradual cooling prevents stress cracks.
How do I make this gluten-free?
Replace the all-purpose flour with ½ cup gluten-free 1:1 baking flour (like Bob's Red Mill) and ensure your Rice Krispies are certified gluten-free. The marshmallows and cream cheese are typically gluten-free, but always check labels. For extra stability, add 1 teaspoon xanthan gum to the cheesecake batter—it mimics gluten's binding properties and prevents crumbling.
Can I add mix-ins to the cheesecake layer?
Fold in ½ cup crushed Oreos or ½ cup caramelized banana for flavor variations. For chocolate lovers, melt ½ cup dark chocolate and swirl it into the batter before baking. Keep mix-ins to ½ cup total to maintain the cheesecake's structure—too many additions can make it dense. Always fold gently to avoid deflating the batter.
How long will this keep at room temperature?
This dessert stays fresh at room temperature for up to 3 days when stored in an airtight container. The cream swirls may soften slightly in warm weather, so refrigerate if your kitchen exceeds 75°F. For longer storage, freeze the fully assembled cheesecake (without swirls) for up to 1 month**. Thaw overnight in the fridge and add fresh swirls before serving.
