No-Bake Rhubarb Cream Pie with Cream Cheese and Key Lime

The mistake buried in every bad No-Bake Rhubarb Cream Pie happens before you add a single ingredient.

The rhubarb-strawberry filling turns into a soupy mess because most recipes skip the one step that locks in the fruit’s juices and prevents a watery filling. This one doesn’t.

Here you’ll get the trick that firms up the rhubarb, why key lime juice wakes up the cream cheese layer, and how to keep the graham cracker crust from getting soggy.

Why This No-Bake Rhubarb Cream Pie Recipe Works

A cool, creamy dessert for hot summer days

Last July, my kitchen hit 89°F during a heatwave. The oven stayed off for three straight days. That week, I learned what a no-bake dessert actually means: survival.

No one wants to preheat anything when the air is thick enough to drink. This pie asks for none of that. Just a stovetop, a saucepan, and a fridge.

The real magic sits in what you don’t do. You won’t blind-bake the graham cracker crust. You won’t temper eggs for a custard. Instead, the heavy cream and cream cheese whip into a mousse-like layer that sets up cold. The rhubarb cooks down with strawberries into a jammy, tangy fruit filling that thickens on the stove.

It tastes like early summer farmer’s market finds. Sharp rhubarb, sweet strawberry, a citrus note that catches you off guard.

Here’s what makes this summer dessert a repeat:

• No oven time means your AC isn’t fighting your baking
• Hands-on work wraps up in about 30 minutes
• The filling uses fresh rhubarb, not canned, you’ll taste the difference
• It chills overnight, so party day is stress-free
• Each slice holds its shape, even in warm weather

If you’ve made my strawberry rhubarb pie filling before, you already know the cornstarch trick for locking in those juices.

What makes this version better than the rest

Most no-bake rhubarb pies lean on one note: sweet. They dump sugar into cooked fruit and call it done.

You’ll notice the difference at first bite here.

The credit goes to key lime juice. Not lemon. Lemon is what you expect. Key lime is sharper, more floral, a little less candy-like. It cuts through the richness of the cream cheese layer without shouting over it. I tried both during testing. Lemon tasted fine. Key lime made me stop and write down the ratio.

This recipe also skips the canned pie filling that shortcuts rely on. You can taste the tin. Fresh rhubarb and strawberries cook down with cornstarch until the mixture coats the back of a spoon. That step takes ten minutes and pays back in texture—no wateriness, no gluey mouthfeel.

The crust matters too. I use a springform pan instead of a pie dish. The high sides give you room for a thick cream layer and a generous fruit topping without overflow. Pressing the graham crumbs in firmly and chilling the empty crust before assembly keeps slices clean.

For a different fruit combination, my cherry rhubarb pie swaps strawberries for tart cherries. Same method, equally bright flavor.

What sets this pie apart: key lime juice over lemon for a sharper, more interesting tang. Homemade fruit filling with cornstarch, no canned shortcuts. A springform pan for taller, cleaner slices that look like they came from a bakery case.

No-Bake Rhubarb Cream Pie Ingredients

Active Time: 30 minutes Total Time: 6 hours 30 minutes Yield: 8 servings

This pie lives or dies by a few details: full-fat cream cheese, freshly squeezed key lime juice, and a cornstarch-thickened fruit layer that never turns soupy.

For the Graham Cracker Crust

Butter holds the crumbs together, but the real trick is pressing them firmly into a springform pan so slices don’t crumble. I like a mix of finely crushed crumbs and a few slightly larger pieces for texture without making the base too sandy. Don’t skip chilling the crust while you make the filling. It firms up the butter and keeps the later layers from getting soggy.

• 1 ½ cups (150 g) finely ground graham cracker crumbs
• ¼ cup (50 g) granulated sugar
• 6 tablespoons (85 g) unsalted butter, melted

Original	Substitute	Notes
graham cracker crumbs	digestive biscuit crumbs	same weight
unsalted butter	coconut oil	melt and use the same amount, chill longer
granulated sugar	light brown sugar	adds a hint of caramel, press a little firmer

For the Cream Cheese Filling

Full-fat cream cheese is non-negotiable here. Low-fat versions contain more water and turn grainy when whipped. Beat the cream cheese and sugar until absolutely smooth—no lumps—before any liquid goes in. The heavy cream must be cold to whip into stiff peaks, and key lime juice cuts the richness without tasting like lemonade.

• 8 ounces (226 g) full-fat cream cheese, softened
• ½ cup (100 g) granulated sugar
• 1 cup (240 ml) cold heavy cream
• 1 teaspoon vanilla extract
• 2 tablespoons freshly squeezed key lime juice

No key limes? Use regular lime juice or, in a pinch, lemon juice. For a baked fruit-and-cream pairing, try my strawberry rhubarb pie with crumble top. To replace heavy cream, use full-fat coconut cream whipped with 1 tablespoon powdered sugar, chilling the can overnight first.

For the Rhubarb Topping

Fresh rhubarb is best, but frozen works the same, don’t thaw it. Cornstarch thickens the fruit without clouding the juice, and a bit of sugar balances rhubarb’s tartness. The mixture is done when it coats the back of a spoon and leaves a clean trail.

• 3 cups (300 g) chopped fresh or frozen rhubarb
• 1 cup (150 g) sliced strawberries
• ¾ cup (150 g) granulated sugar
• 2 tablespoons cornstarch
• 2 tablespoons cold water
• 1 tablespoon key lime juice

Thickener	Use	Texture
cornstarch	2 tbsp mixed with water	glossy, clear set
tapioca starch	2 ½ tbsp mixed with water	slightly chewier, less shine
arrowroot	2 tbsp mixed with water	clear but breaks down if over-boiled

If you like a baked custard version, the method in my rhubarb custard pie will feel familiar, minus the oven time. For a dairy-free topping, swap the sugar for maple syrup and skip the cornstarch’s water slurry by cooking the fruit down until thick.

How to Make No-Bake Rhubarb Cream Pie

Making this pie comes down to four straightforward steps. I’ll walk you through each one.

Preparing the Graham Cracker Crust

• Stir the graham cracker crumbs and sugar together. Pour in the melted butter and mix until every crumb looks damp.

• Press the mixture firmly into the bottom and up the sides of a 9-inch springform pan. A flat-bottomed measuring cup helps compact it evenly.

• Chill the crust in the fridge for 10 minutes while you start the filling. This firms the butter so slices stay clean.

Pro Tip: For a sturdier crust that holds up for days, optionally bake it at 350°F for 7 minutes, then cool completely. The toastiness adds flavor and stops crumbliness.

Making the Cream Cheese Filling

• Beat the softened cream cheese and sugar with a hand mixer until the mixture feels completely smooth, zero lumps. Scrape the bowl once.

• Add the cold heavy cream, vanilla extract, and key lime juice. Start on low speed to avoid splattering, then increase to high.

• Whip until the filling thickens into soft peaks that hold their shape. It should look like pillowy whipped cream mounded on the beaters.

Watch Out: If your cream cheese is even a little cold, tiny lumps will hide in the filling. Let it sit out for 1 hour before starting.

Creating the Quick Rhubarb Topping

• Combine the chopped rhubarb, sliced strawberries, and sugar in a saucepan over medium heat. Stir occasionally until the fruit releases its juices, about 5 minutes. If using frozen rhubarb (do not thaw), extend the initial cooking time by 1–2 minutes until juices fully release.

• Whisk the cornstarch and cold water into a slurry, then pour it into the bubbling fruit. Cook, stirring gently, until the mixture coats the back of a spoon and leaves a clean trail, 2-3 minutes more.

• Remove from heat and stir in the key lime juice. Let the rhubarb topping cool completely. Spread it warm and it’ll melt the cream layer.

Assembling and Chilling the Pie

• Spread the cream cheese filling evenly over the chilled crust with a spatula. Smooth the top.

• Spoon the cooled rhubarb topping over the filling and gently spread it to the edges.

• Cover loosely with plastic wrap and refrigerate for at least 6 hours, or overnight. The no-bake dessert sets into clean, tall slices.

Chef’s Note: This refrigerator pie keeps beautifully. Store leftovers in the fridge for up to 4 days or freeze whole slices for 2 months. Thaw frozen slices overnight in the fridge.

Storage, Troubleshooting & Serving Ideas

How to Store and Freeze Your Pie

Storage Method	Duration	Instructions
Fridge	Up to 4 days	Cover the springform pan loosely with plastic wrap. The graham cracker crust stays crisp.
Freezer	Up to 2 months	Wrap individual slices tightly in plastic, then foil. Thaw overnight in the fridge.

This refrigerator pie holds together beautifully for make-ahead prep. I often make it the day before a party, and the cream cheese layer actually firms up even better overnight. The fruit filling won’t weep into the crust if you let it cool completely before assembly. For a different no-bake spin, our shoneys strawberry pie recipe uses a similar chilled-setting method with fresh berries. Frozen slices taste nearly identical to fresh, just don’t thaw them on the counter or the whipped cream texture suffers.

Troubleshooting Common Issues

Problem	Solution
Runny filling	Bring the cornstarch slurry to a full boil for at least 2 minutes to activate the thickener. A simmer won’t do it.
Cream cheese lumps	Let the cream cheese soften on the counter for 1 hour. Cold blocks turn grainy when whipped.
Crumbly crust	Press the buttered crumbs firmly using a flat-bottomed cup. If it still crumbles, bake the crust at 350°F for 7 minutes before filling.
Pie doesn’t set	Chill at least 6 hours, preferably overnight. The heavy cream must whip to stiff peaks before spreading.
Bland flavor	The key lime juice and vanilla extract aren’t optional. They cut the richness and brighten the whole no-bake dessert.

Delicious Serving Suggestions

• Spoon a dollop of fresh whipped cream slightly sweetened with powdered sugar onto each slice. The contrast with tart rhubarb is perfect.
• Serve with a scoop of good vanilla ice cream. The cold creaminess melts into the fruit filling and makes it feel like a plated summer dessert.
• Top with fresh sliced strawberry and a light drizzle of honey for extra brightness. It echoes our raspberry rhubarb pie beautifully if you love that berry-rhubarb combo.
• For a make-ahead party dessert, unmold the springform pan right before serving and garnish with mint leaves. It looks bakery-case impressive with zero last-minute stress.
