No Bake Lemon Blueberry

This no-bake lemon blueberry dessert delivers layers of tangy lemon cream and sweet blueberries on a buttery graham cracker crust without ever turning on your oven. The bright citrus and berry combination creates the perfect balance of flavors in each refreshing bite.

I originally created this recipe during a summer heatwave when the thought of turning on my oven seemed unbearable. Now it's become my signature dessert for every family gathering from Memorial Day through Labor Day.

• Graham cracker crumbs: Form the perfect crisp yet tender foundation that holds up to the creamy filling
• Butter: Binds the crust together while adding rich flavor; look for unsalted to control the overall saltiness
• Cream cheese: Provides the luxurious tangy base for the filling; choose full-fat for the creamiest texture
• Sweetened condensed milk: Adds sweetness while helping the filling set properly without baking
• Fresh lemon juice: Cuts through the richness with bright acidity; always use fresh rather than bottled for best flavor
• Lemon zest: Intensifies the citrus flavor without additional liquid; use organic lemons if possible
• Fresh blueberries: Burst with summer sweetness; choose plump firm berries with a silvery bloom
• Cornstarch: Thickens the blueberry topping to the perfect consistency without changing the flavor

Step-by-Step Instructions

Create the foundation:

Mix graham cracker crumbs with melted butter and sugar until it resembles wet sand. The texture should clump together when pressed between your fingers. Press firmly into your baking dish using the bottom of a measuring cup for an even compact layer. Chill for at least 15 minutes to set.

Whip the lemon filling:

Beat room temperature cream cheese on medium speed for 2-3 minutes until completely smooth with no lumps whatsoever. Gradually pour in condensed milk while continuing to mix. Add lemon juice slowly; the mixture will begin to thicken as the acid reacts with the dairy. Fold in lemon zest and vanilla just until incorporated for maximum flavor distribution.

Cook the blueberry topping:

Simmer blueberries with sugar and lemon juice in a saucepan over medium heat, crushing some berries against the side of the pan with your spoon while leaving others whole for texture contrast. Cook until the berries release their juices, about 5 minutes. Add cornstarch slurry and continue cooking until the mixture coats the back of a spoon and leaves a clear path when you run your finger through it.

Assemble and chill:

Pour the lemon filling over the chilled crust, spreading into an even layer reaching all corners. Allow to set in the refrigerator for 30 minutes before adding cooled blueberry topping. Spread the blueberry mixture gently over the lemon layer without pressing too hard. Refrigerate at least 3 hours or preferably overnight until completely set and flavors have melded.

The fresh lemon juice truly makes this dessert special. I learned from my grandmother to always roll the lemons firmly against the counter before juicing to break down the internal membranes and extract maximum juice. Something about the bright yellow against the deep purple blueberries reminds me of summer Sunday dinners on our porch when I was growing up.

Perfect Make-Ahead Dessert

This dessert actually improves with time in the refrigerator. The graham cracker crust softens slightly while the flavors deepen and meld together. I recommend making it the day before serving for optimal texture and taste. When ready to serve, simply remove from the refrigerator about 15 minutes before slicing to allow the filling to soften slightly for the perfect creamy consistency.

Seasonal Berry Variations

While blueberries create a classic pairing with lemon, this versatile dessert works beautifully with other seasonal berries. Try strawberries in late spring, blackberries in late summer, or even a mixed berry combination. The cooking process remains the same regardless of which berries you choose. For raspberries, you might want to strain some of the seeds if desired. During winter months, frozen berries work perfectly; just thaw and drain excess liquid before cooking.

Elegant Serving Suggestions

Transform this casual dessert into an elegant finale by serving in individual glasses or ramekins. Layer the components trifle-style with extra berries between layers for visual appeal. Top with a dollop of freshly whipped cream just before serving and add a sprig of mint or a thin lemon slice for garnish. For special occasions, serve alongside a small glass of limoncello or prosecco for a sophisticated touch.
