This No-bake Lemon Dazzling Blueberry Cream Cake is a bright and fresh treat that’s perfect when you want something sweet but light. The zesty lemon flavor pairs beautifully with the sweet, juicy blueberries, all wrapped up in a creamy, smooth filling that sits on a crumbly, buttery base. It’s the kind of dessert that shines with every bite—refreshing and full of color.
I love making this cake on warm days because it doesn’t need an oven, which means no extra heat in the kitchen! The mix of tart lemon and sweet blueberries always impresses guests, and the creamy texture feels like a little cloud of happiness on your tongue. Plus, it’s so simple to put together, it feels like a little magic trick every time.
My favorite way to serve this cake is chilled with a cup of tea or iced coffee—it’s just the right balance to brighten up any afternoon. If you want to add a little sparkle, a few fresh lemon slices or extra blueberries on top make it look as good as it tastes. This cake is definitely one I keep coming back to when I want something that feels special without a lot of fuss.
Key Ingredients & Substitutions
Graham Cracker Crust: This crumbly base gives a nice buttery crunch. If you can’t find graham crackers, digestive biscuits or even vanilla wafers work well. For a gluten-free crust, try gluten-free cookies.
Blueberries: Fresh or frozen blueberries both work. Frozen ones need to be thawed and drained to avoid extra juice. The blueberry layer adds a sweet, slightly tart punch that complements the lemon perfectly.
Cream Cheese & Heavy Cream: Cream cheese provides richness and a smooth texture. Make sure it’s softened for easy mixing. Cold heavy cream whips best and adds lightness to the filling. For a dairy-free option, try vegan cream cheese and coconut cream.
Lemon Juice & Zest: Fresh lemon juice and zest brighten up the cream filling with fresh citrus flavor. Bottled lemon juice lacks zest and brightness, so try to use fresh lemons if you can.
How Do I Get the Blueberry Layer Just Right Without It Being Too Runny?
Creating the perfect blueberry layer is key for keeping your cake neat and tasty. Here’s a simple way to do it:
- Warm blueberries with sugar and lemon juice over medium heat to draw out juices.
- Mix cornstarch with cold water to make a slurry, then stir it in.
- Cook 1-2 minutes until thickened — it should coat the back of a spoon, not pour freely.
- Cool completely before layering to avoid mixing into the cream.
Patience here helps keep those beautiful layers clean and tasty!
Equipment You’ll Need
- Springform pan or an 8-inch square dish – I prefer a springform so you can easily take the cake out without damaging it.
- Mixing bowls – useful for beating the cream cheese and whipping the cream separately.
- Saucepan – for cooking the blueberry mixture to thicken it just right.
- Whisk and spatula – handy for stirring berries and folding whipped cream into the filling.
- Electric mixer or hand whisk – makes whipping heavy cream faster and easier.
- Measuring cups and spoons – for precise ingredients and liquids.
Flavor Variations & Add-Ins
- Replace blueberries with raspberries or blackberries for different berry flavors that still brighten the cake.
- Swirl in some jams or fruit preserves into the cream filling for extra fruit flavor.
- Add a splash of liqueur like Grand Marnier or Chambord to give it a boozy twist—great for adult gatherings.
- Use coconut whipped cream to make it dairy-free and add a subtle tropical taste.

How Much Time Will You Need?
This dessert takes about 20 minutes to prepare and another 4 hours (or overnight) to chill and set. The chilling time is essential to allow the layers to firm up and the flavors to meld beautifully.
Step-by-Step Instructions:
1. Prepare the Crust:
In a bowl, mix together the graham cracker crumbs, melted butter, and sugar until everything is combined and crumbly. Press this mixture firmly and evenly into the bottom of your 8-inch springform pan or square dish. Put it in the fridge to chill while you get everything else ready.
2. Make the Blueberry Layer:
Place the blueberries, sugar, and lemon juice in a small saucepan over medium heat. Cook, stirring occasionally, until the blueberries begin to release their juices and the sugar dissolves—about 5 to 7 minutes. Stir in the cornstarch slurry, then cook for another 1 to 2 minutes until the mixture thickens nicely. Take it off the heat and let it cool completely before using.
3. Prepare the Lemon Cream Filling:
In a large bowl, beat the softened cream cheese with powdered sugar until smooth and creamy. In a separate bowl, whip the heavy cream along with lemon juice, lemon zest, and vanilla extract until you see stiff peaks form—this will give the filling its light, fluffy texture.
4. Combine the Filling:
Gently fold the whipped lemon cream into the cream cheese mixture. Mix carefully until everything is combined and creamy, but keep the airiness from the whipped cream.
5. Assemble the Cake:
Spread half of the lemon cream filling over the chilled crust in the pan. Then carefully spoon and spread the cooled blueberry layer evenly over the lemon filling. Top with the remaining lemon cream filling and smooth the surface with a spatula.
6. Chill:
Cover the cake with plastic wrap or a lid, then chill it in the refrigerator for at least 4 hours, or overnight if possible. This helps the cake set perfectly and the flavors to blend.
7. Prepare the Topping:
Before serving, whip the remaining half cup of heavy cream with powdered sugar until stiff peaks form. Pipe or dollop the whipped cream around the edges of the cake for a pretty finish.
8. Garnish and Serve:
Decorate the top with fresh blueberries, lemon slices, and curls of lemon zest. Dust lightly with powdered sugar if you like a delicate snowy look. Slice and serve chilled—it’s the perfect refreshing dessert for warm days!
Can I Use Frozen Blueberries Instead of Fresh?
Yes, you can use frozen blueberries! Just thaw them completely and drain any excess juice before cooking to prevent the blueberry layer from becoming too watery.
How Long Can I Store This Cake?
This cake keeps well in the refrigerator for up to 3 days. Be sure to cover it tightly with plastic wrap or store in an airtight container to maintain freshness.
Can I Make This Cake Ahead of Time?
Absolutely! Prepare the cake a day in advance and chill overnight—this actually helps the flavors develop and makes slicing easier. Just add the whipped cream topping and garnishes right before serving.
What Can I Substitute for Graham Crackers in the Crust?
If you don’t have graham crackers, digestive biscuits or vanilla wafers work great too. For a gluten-free option, use gluten-free cookies or crust mix.
