Ingredients Notes

What makes this dessert truly shine is the combination of fresh, tangy flavors with creamy, melt-in-your-mouth textures. Here's what you need to know about the key ingredients that bring it all together.

The base of this dessert is made from butter cookies or graham crackers, crushed into fine crumbs and mixed with melted butter. This mixture forms a firm, flavorful crust that holds everything together. I personally love using lemon-flavored cookies for an extra zing, but plain grahams or even vanilla wafers work beautifully.

Cream cheese is the heart of the creamy layer. It gives the dessert body and a slight tang that pairs wonderfully with the lemon. Be sure to use full-fat cream cheese for the richest texture, and make sure it’s softened so it blends easily with the other ingredients.

The lemon flavor comes from both fresh lemon juice and zest, which give the dessert a vibrant citrus punch. Don’t skip the zest—it’s where the real lemon aroma lives, and it takes the flavor to the next level.

Whipped topping (like Cool Whip) adds lightness and volume to the cream layer. It keeps the texture airy and helps everything set up nicely once chilled. You can also use homemade whipped cream if you prefer, but the store-bought kind makes this recipe ultra convenient.

And of course, there are the blueberries—juicy, sweet, and just a little tart. You can use fresh berries when they’re in season or frozen ones (thawed and drained) if that’s what you have. They add pops of color and flavor throughout the dessert.

As for equipment, all you need is an 8x8 or 9x9-inch square pan, a mixing bowl, a hand mixer or stand mixer, and a spatula. A food processor makes quick work of the crust, but it’s not essential.

How To Make This No Bake Lemon Blueberry Dessert

Creating this chilled delight is easier than you'd think. With just a handful of ingredients and no oven time, you’ll have a dreamy dessert that’s as pretty as it is delicious.

Start by making the crust. Crush your cookies or graham crackers into fine crumbs using a food processor or by sealing them in a zip-top bag and smashing with a rolling pin. Mix the crumbs with melted butter until they resemble wet sand. Press the mixture firmly into the bottom of your baking pan, making sure it’s evenly packed. Pop it in the fridge while you work on the filling.

In a large bowl, beat the softened cream cheese until smooth and fluffy. This step is important—no lumps allowed! Add in the powdered sugar, lemon juice, and lemon zest, then continue mixing until everything is fully incorporated. The mixture should be thick and creamy, with a bright lemony aroma.

Gently fold in the whipped topping, being careful not to deflate it. This will lighten the mixture and help it set into that irresistible mousse-like texture. Once combined, spread the cream mixture evenly over the chilled crust, smoothing the top with a spatula.

Scatter the blueberries generously over the top, pressing them in just slightly so they nestle into the cream layer. If you want an extra decorative touch, reserve a few berries and a bit of lemon zest to sprinkle on right before serving.

Cover the dish and refrigerate for at least 4 hours, or ideally overnight. This chill time allows the layers to firm up and the flavors to meld into that perfect tangy-sweet harmony.

When it’s ready, slice into neat squares and serve chilled. Each bite delivers creamy lemon filling, sweet bursts of blueberry, and a buttery crust that brings it all together.

Storage Options

One of the best things about this no bake dessert is how well it stores, making it ideal for planning ahead or enjoying leftovers.

To store in the fridge, cover the pan tightly with plastic wrap or transfer individual portions to airtight containers. It will stay fresh and delicious for up to 4 days. The crust may soften slightly over time, but the flavor remains spot-on.

If you want to freeze it, wrap the entire dish in foil and place it in a freezer-safe bag, or portion out individual slices. It freezes well for up to 1 month. Just let it thaw overnight in the refrigerator before serving.

Avoid leaving it at room temperature too long, especially in warm weather. Since it contains cream cheese and whipped topping, it’s best served cold to maintain its texture and safety.

To re-serve, simply cut a slice and enjoy straight from the fridge. There’s no need to reheat—this dessert is all about that cool, creamy bite.

Variations and Substitutions

One of the reasons this dessert is a repeat favorite in my kitchen is how easily it adapts to whatever I have on hand or whatever flavors I’m craving.

Not a blueberry fan? Swap them out for raspberries, strawberries, or even a mix of berries. Chopped peaches or mango could also work beautifully for a tropical twist.

If you don’t have lemon, try using lime juice and zest instead. Lime brings a slightly different citrus note that’s just as refreshing and pairs well with all kinds of fruit.

For the crust, try using chocolate wafer cookies, gingersnaps, or even pretzels if you like a salty-sweet combo. Each base brings its own personality to the dish.

Want to make it dairy-free? Look for dairy-free cream cheese and use coconut whipped topping. It won’t taste exactly the same, but the creamy-citrus essence will still shine through.

Feel free to get creative with toppings too—add a drizzle of blueberry sauce, a dollop of whipped cream, or a few mint leaves for an elegant finish.

This No Bake Lemon Blueberry Dessert is endlessly adaptable, so don’t be afraid to make it your own. Once you’ve tried it, I promise it’ll become a regular in your dessert rotation.
