This easy blueberry cake with whipped lemon frosting is a tender, buttery scratch cake made with fresh blueberries, lemon zest, and everyday pantry ingredients. Bake it in a 9-inch round pan or an 8-inch square pan, then finish it with cool, airy lemon whipped cream for a simple dessert that serves about eight people.
Every bite combines juicy berries, bright citrus, and a soft golden crumb beneath a cloudlike frosting. The cake takes about 20–25 minutes to prepare, 35–42 minutes to bake, and should cool completely before frosting so the whipped cream stays light and beautifully spreadable.

This blueberry cake has the comfort of a classic butter cake with the fresh flavor of a summer berry dessert. The crumb is soft but sturdy enough to hold plenty of blueberries, while lemon zest gives the batter a fragrant citrus note without making it sharply sour.
The whipped lemon frosting is especially appealing because it is lighter than buttercream and less dense than cream cheese frosting. Cold heavy cream, confectioners’ sugar, lemon zest, lemon juice, and vanilla become a smooth, airy topping in about 10 minutes.
It is also a practical one-pan bake. There is no need to stack layers, prepare a complicated filling, or decorate with piping skills, making this cake suitable for a weekday treat as well as a casual celebration.

Ingredients You’ll Need
The cake begins with 2 cups of all-purpose flour, baking powder, and fine salt. These dry ingredients provide structure and lift, while softened unsalted butter and granulated sugar create the rich, tender base that makes this cake taste homemade.
Use two large eggs at room temperature when possible. Room-temperature eggs blend more easily into the creamed butter mixture, helping the batter stay cohesive rather than looking curdled.
Milk loosens the batter and keeps the baked cake tender. Vanilla extract rounds out the flavor, while finely grated zest from one lemon perfumes the cake with bright citrus oils.
Fresh blueberries are ideal because they hold their shape and create colorful pockets of fruit. Toss the 1 1/2 cups of berries with one tablespoon of flour immediately before folding them into the batter.
For the topping, measure cold heavy whipping cream, confectioners’ sugar, one teaspoon lemon zest, one to two tablespoons lemon juice, and vanilla extract. Start with one tablespoon of lemon juice, then add more if you prefer a stronger citrus flavor.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then grease and line a 9-inch round cake pan or an 8-inch square pan with parchment. Leave a little parchment extending over two sides if you are using the square pan, as it will make lifting the cooled cake easier.
Step 2: Whisk the 2 cups of flour, baking powder, and fine salt in a medium bowl. Breaking up any small lumps now means the dry mixture can be incorporated quickly later without overmixing the batter.
Step 3: Place the softened butter and granulated sugar in a large bowl and beat for about 2–3 minutes, until pale and fluffy. This step adds air to the mixture, so do not rush it or use butter that is cold and firm.
Step 4: Beat in the eggs one at a time, waiting until the first egg is incorporated before adding the second. Mix in the vanilla extract and finely grated lemon zest, scraping the bowl once so the flavorings are evenly distributed.
Step 5: Add the dry ingredients in three additions, alternating with the milk. Begin and end with the dry ingredients, and mix only until no large streaks of flour remain; a few small lumps are preferable to an overworked batter.
Step 6: Toss the blueberries gently with one tablespoon of flour. Fold them into the batter with a spatula using broad, careful strokes so the berries remain intact and the batter does not become tough.
Step 7: Spread the batter evenly in the prepared pan and smooth the top. Bake for 35–42 minutes, checking near the lower end of the range; the cake is ready when the center springs back lightly and a toothpick comes out clean or with a few moist crumbs.
Step 8: Let the cake cool in the pan for 10–15 minutes, then transfer it to a rack. Allow it to cool completely, which usually takes another 45–60 minutes, before adding the frosting.
Step 9: For the frosting, whip the cold heavy cream, confectioners’ sugar, lemon zest, lemon juice, and vanilla to medium-stiff peaks. Spread the frosting over the completely cooled cake, then add a few blueberries or a little extra lemon zest if desired.
Pro Tips for a Tender Blueberry Cake
Properly softened butter should be cool to the touch but easy to press with a fingertip. Melted butter will not create the same fluffy creamed mixture, while overly warm butter can make the finished crumb heavy.
Measure flour by weight for the most consistent result, or spoon it into measuring cups and level the tops. Scooping directly from the flour container can pack in extra flour and produce a dry cake.
Flouring the blueberries helps suspend them throughout the batter and reduces sinking. If you use frozen berries, do not thaw them first; fold them in while frozen and expect approximately five extra minutes of baking.
Use a gentle hand once the flour and milk are added. Mixing just until combined keeps the cake soft, and it also prevents the blueberries from breaking and streaking the batter more than necessary.
Whipped cream is sensitive to heat, so keep the cream cold and never frost the cake while it is warm. If your kitchen is hot, chill the cooled cake and the prepared frosting briefly before assembling.

Serving, Storage, and Variations
Serve this cake chilled or let it stand at room temperature for a short time before slicing. A sharp knife makes clean cuts through the frosting, and each slice is lovely with a few fresh blueberries scattered on the plate.
Because the frosting contains whipped cream, store the finished cake covered in the refrigerator. It is best enjoyed while the topping is fresh, and leftovers should remain refrigerated rather than sitting out for an extended period.
For a softer crumb, some bakers use 1 1/2 cups cake flour instead of all-purpose flour. Another published variation replaces part of the milk with 1/2 cup sour cream or Greek yogurt, creating a richer, slightly tangier cake.
This recipe is written for one 9-inch round or one 8-inch square cake. Layer-cake adaptations commonly double both the cake and frosting quantities, but a larger or deeper cake may require adjusted baking time and careful testing in the center.
Cream-cheese and mascarpone lemon frostings are also popular choices, although they are denser than true whipped cream. For a crisp, savory side dish to balance a dessert table, consider our cheesy tater tot casserole for a separate meal or brunch spread.
Common Questions About This Cake
Can I use frozen blueberries? Yes. Add them directly from the freezer rather than thawing them, and plan for approximately five extra minutes in the oven. Frozen berries may tint the batter slightly, but the cake will still be delicious.
How do I know the cake is baked? The center should spring back lightly when pressed, and a toothpick inserted in the middle should come out clean or with a few moist crumbs. A toothpick covered in wet batter means the cake needs more time.
Can I frost the cake before it is fully cool? No. Warm cake will soften or melt whipped cream frosting, causing it to slide or lose volume. Cooling the cake completely is one of the most important steps in this recipe.
Can I make the frosting less tart? Begin with one tablespoon of lemon juice and taste before adding the second tablespoon. The lemon zest provides plenty of citrus aroma, so the juice can be adjusted to suit your preference.
