This No-Bake Lemon Blueberry Cream Cake is my answer to those sunny days when you crave something chilled and luscious but do not want to turn on your oven. It is all about plush lemon cream filling paired with bursts of fresh blueberries on a lightly buttery graham cracker base. You end up with the kind of dessert that disappears fast at summer gatherings.
The first time I set this on our summer picnic table it vanished before I could grab a second slice. The tangy creaminess always draws people in and guests ask for the recipe year after year.
Ingredients
- Graham cracker crumbs: For a crumbly no bake crust always check they are fresh and not stale
- Melted butter: Binds the crust and adds a buttery note use unsalted for best balance
- Cream cheese: Softened to blend smoothly into the filling select full fat for maximum creaminess
- Granulated sugar: Sweetens the filling just enough without overpowering the lemon
- Lemon zest: Adds punchy lemon flavor always zest before juicing and use organic lemons if you can
- Lemon juice: Gives the cake real brightness and tang
- Heavy whipping cream: When freshly whipped it makes the filling airy and light use well chilled cream
- Fresh blueberries: Bursts of sweet tart flavor and color select plump deeply colored berries
- Lemon zest and extra blueberries for garnish: They make the cake look as good as it tastes
Instructions
- Prepare the Crust:
- Combine graham cracker crumbs and melted butter in a bowl until evenly moistened. Press the mixture firmly and evenly into the bottom of a 9 by 9 inch pan using the bottom of a measuring cup to compact the layer. Chill in the refrigerator while you prepare the filling which helps the base set.
- Make the Lemon Cream Filling:
- In a large bowl beat softened cream cheese and sugar together until absolutely smooth and creamy with no lumps. This can take several minutes with a hand mixer. Scrape down the bowl and beat in the lemon zest and juice to give it vibrant flavor.
- Whip the Cream:
- In a separate chilled bowl whip heavy cream until it forms soft peaks. Use a cold bowl and beaters whips up fluffier cream which keeps the filling light.
- Fold and Layer:
- Gently fold the whipped cream into the lemon cream cheese mixture. Do not rush this step use a spatula and light hand so you do not deflate the mousse. Spread half the filling over the chilled crust smoothing to the edges then scatter on a generous layer of fresh blueberries.
- Top with Remaining Filling:
- Spoon the rest of the lemony filling on top and use an offset spatula to create swirls or a smooth finish.
- Chill and Garnish:
- Cover the cake and refrigerate for at least four hours or overnight. This extended chilling time ensures the cake slices neatly. Before serving dust with extra lemon zest and pile on more fresh blueberries for color and juicy sparkle.

The burst of lemon zest in this cake is always my favorite part. One summer my niece insisted on helping with the blueberries and it turned into a sweet new tradition. There is just something about swirling fresh lemon rind on top together that makes the dessert even more joyful.
Storage Tips
This cake stores beautifully in the fridge for three to four days. Cover tightly with plastic wrap to keep it from picking up fridge flavors. If you want to save leftovers longer freeze well wrapped slices and let them thaw overnight in the fridge for a treat later.
Ingredient Substitutions
Swap graham crackers for digestive biscuits if you are in the UK or want a toastier flavor. For a lighter result use neufchâtel cheese in place of cream cheese. Frozen blueberries work if you drain them well and use them straight from the freezer to avoid excess liquid in the cake.
Serving Suggestions
Serve cold straight from the fridge for cleanest slices. For a festive look top each serving with a dollop of whipped cream and extra berries. It also makes a wonderful brunch dessert paired with iced tea or sparkling lemonade.
