What Ingredients You Will Need

This fluffernutter cheesecake recipe easy best birthday dessert ever keeps things simple and stress-free. Here’s everything you’ll need to whip up this dreamy dessert (plus a few tips to help you pick the best):

For the Crust:
- Graham cracker crumbs (1 1/2 cups/150g, about 12 full sheets) – adds a classic, buttery crunch. You can use gluten-free grahams if needed.
- Unsalted butter (6 tbsp/85g, melted) – helps the crust hold together and adds richness.
- Granulated sugar (2 tbsp/25g) – just enough to sweeten the base.
- Pinch of salt – balances the sweetness and brings out flavor.
For the Filling:
- Cream cheese (3 blocks/24 oz/680g, softened) – use full-fat for the creamiest result. I like Philadelphia, but store brand works fine.
- Granulated sugar (3/4 cup/150g) – not too sweet, just right.
- Large eggs (3) – room temperature for smooth blending.
- Sour cream (1/2 cup/120g) – adds tang and keeps it moist.
- Vanilla extract (2 tsp) – real vanilla gives the best flavor.
- Creamy peanut butter (2/3 cup/170g) – classic Skippy or Jif work great. Natural peanut butters can be used if well stirred.
- Marshmallow creme/fluff (1 cup/240g) – Jet-Puffed or Marshmallow Fluff are my go-tos. Adds that signature fluffernutter gooeyness.
- Pinch of salt – just a little to balance all the sweet stuff.
For the Swirl/Topping:
- Extra peanut butter (2 tbsp/30g, melted) – to drizzle over the top.
- Extra marshmallow creme (2 tbsp/30g) – dolloped on for a fun look.
- Optional: Chopped roasted peanuts or mini marshmallows for garnish – adds crunch and makes it birthday-ready.

If you need to make it gluten-free, just swap the graham crackers for your favorite gluten-free brand. For a nut-free version, try sunflower seed butter instead of peanut butter. I’ve even swapped sour cream for plain Greek yogurt in a pinch—no one noticed! And if you’re feeling adventurous, a chocolate cookie crust totally works too, just saying.

Equipment Needed

9-inch (23cm) springform pan – The classic cheesecake essential. If you don’t have one, you can use a deep 9-inch cake pan lined with parchment, but springform is so much easier for serving.
Electric mixer or stand mixer – For that ultra-smooth filling. A sturdy whisk and some elbow grease will work, but trust me, a mixer saves time.
Mixing bowls – At least two, for the crust and filling. I use glass, but metal or plastic is fine.
Rubber spatula – For scraping every last bit of batter (because who wants to waste cheesecake?).
Measuring cups and spoons – Accuracy counts, especially with cheesecake.
Aluminum foil – To wrap the pan base if you’re worried about leaks, especially if using a springform pan.
Small microwave-safe bowl – For melting peanut butter for drizzling.

If you’re short on springform pans, I’ve baked half-batches in a glass pie plate—just reduce the bake time a bit. Cleaning tip: let your mixer blades soak in hot water right after use to avoid sticky peanut butter cement. And honestly, you don’t need top-of-the-line tools; my old hand mixer has seen more cheesecakes than I can count and never lets me down.

How to Make Fluffernutter Cheesecake: Step-by-Step

Prep Your Pan and Oven
Preheat oven to 325°F (160°C). Line the bottom of a 9-inch (23cm) springform pan with parchment paper and lightly grease the sides. If you’re worried about leaking, wrap a layer of foil around the outside base.
Make the Crust
In a medium bowl, combine 1 1/2 cups (150g) graham cracker crumbs, 6 tbsp (85g) melted butter, 2 tbsp (25g) sugar, and a pinch of salt. Mix until it looks like damp sand. Press firmly into the bottom of the pan (I use the flat bottom of a measuring cup). Bake for 10 minutes, then let cool while you make the filling.
Prepare the Cheesecake Filling
In a large bowl, beat 24 oz (680g) softened cream cheese and 3/4 cup (150g) sugar until creamy and smooth—about 2 minutes. Scrape the bowl. Add 3 eggs, one at a time, beating just until each is incorporated. Don’t overmix (it can crack later). Mix in 1/2 cup (120g) sour cream, 2 tsp vanilla extract, and a pinch of salt. The batter should be silky and lump-free.
Swirl in Peanut Butter & Marshmallow
Divide the batter in half. To one half, fold in 2/3 cup (170g) creamy peanut butter. To the other half, fold in 1 cup (240g) marshmallow creme. Dollop big scoops of each batter alternately over the crust, then use a butter knife to gently swirl. Don’t overdo it—just a few turns for that marbled effect.
Bake
Bake at 325°F (160°C) for 45–55 minutes. The edges should look set, but the center will still jiggle slightly (like set Jello). If it’s browning too fast, tent with foil. When done, turn off oven, crack door open, and let cheesecake cool inside for 1 hour. This helps prevent cracks.
Chill Completely
Remove cheesecake from oven and cool to room temp, then refrigerate at least 4 hours (overnight is best). Don’t rush—this is where the magic happens!
Add Swirl & Serve
Just before serving, microwave 2 tbsp (30g) peanut butter until melted. Drizzle over the cheesecake. Dollop 2 tbsp (30g) marshmallow creme on top and swirl gently. Sprinkle chopped roasted peanuts or mini marshmallows if you like.

Troubleshooting: If your cheesecake cracks, don’t stress! The drizzle and toppings cover everything. If the crust feels crumbly, press it down more firmly next time. And if you see lumps in your batter, let the cream cheese soften longer before mixing.

Pro tip: For the cleanest slices, dip your knife in hot water and wipe between cuts. Trust me—it makes those birthday photos extra pretty.

Cooking Tips & Techniques

Room Temperature Ingredients: Always let your cream cheese, eggs, and sour cream come to room temp before mixing. Cold ingredients can cause lumps and uneven baking. Honestly, I’ve tried to rush it before and ended up with little cream cheese bits—no fun.
Don’t Overbeat: Once you add the eggs, mix just until combined. Overmixing adds air, which can cause big cracks or a weird, puffy texture.
Crust Perfection: Use a flat-bottomed glass or measuring cup to really pack down the crust. A loose crust will crumble when you slice, and nobody wants that mess at a birthday party.
Water Bath Optional: This recipe is forgiving, so you don’t need a water bath. But if you want extra insurance against cracks, place a pan of hot water on the rack below your cheesecake in the oven—just don’t put the cheesecake in the water.
Swirl Smart: For those beautiful marbled swirls, use a butter knife or skewer and don’t overdo it. Too much swirling just blends everything together (been there, done that—learned my lesson!). Less is more.
Chill Time: Don’t skip the chill! The flavors and texture set up perfectly overnight. If you’re short on time, at least give it 4 hours in the fridge.
Cleanup Tip: Marshmallow creme is sticky—spray your measuring spoon with a little oil first. It slides right off, no scraping required.

If you’re making this for the first time, don’t worry if it’s not “bakery perfect.” With the drizzles and swirls, it always looks and tastes amazing. And if the top gets a little toasty, call it “caramelized”—trust me, everyone will love it.

Variations & Adaptations

Gluten-Free Fluffernutter Cheesecake: Swap regular graham crackers for gluten-free ones—everything else stays the same. One of my friends is celiac, and she swears this version is just as dreamy.
Chocolate Fluffernutter Cheesecake: Use chocolate cookie crumbs for the crust, and add a handful of mini chocolate chips to the peanut butter batter. It’s a little decadent, a lot delicious.
Peanut-Free Version: Substitute creamy sunflower seed butter for peanut butter. The flavor’s slightly different, but still totally crave-worthy.
Mini Cheesecakes: Divide the batter among lined muffin tins for personal-sized treats! Bake 18–20 minutes. Kids love these, and no slicing fuss.
Extra Marshmallow Swirl: For an even gooier treat, swirl more marshmallow creme on top before baking. I tried this for my brother’s birthday—he declared it “the best cheesecake ever.”

If you’re feeling creative, add a layer of sliced bananas over the crust before pouring in the filling. It’s a nod to the classic fluffernutter sandwich and tastes like childhood in a bite!

Serving & Storage Suggestions

This fluffernutter cheesecake recipe easy best birthday dessert ever is best served cold, straight from the fridge. The texture is creamy and the flavors are most intense when chilled. For a true birthday showstopper, add a few candles and a scatter of sprinkles or chopped peanuts on top—Instagram moment, guaranteed!

Best Pairings: Serve with a tall glass of cold milk or hot coffee. A scoop of vanilla ice cream on the side? Why not!
Storage: Store leftovers (if you have any!) covered in the refrigerator for up to 5 days. The flavors meld as it sits, so day two is somehow even better.
Freezing: Cheesecake freezes well. Wrap slices individually in plastic wrap, then foil, and freeze up to 2 months. Thaw overnight in the fridge, and it’s ready to go.
Reheating: If you like your cheesecake a little softer, let a slice sit at room temp for 10–15 minutes before eating. I wouldn’t microwave it—the marshmallow gets weirdly gooey.

One last tip: Flavors deepen over time, so making this the night before your party is a win-win. Let’s face it, one less thing to do on birthday morning is always a good idea!
