Lemon Blueberry Layer Cake with Cream Cheese Frosting
Lemon Blueberry
This Lemon Blueberry Layer Cake feels like summer wrapped up in a slice — bright lemon sponge spiked with fresh zest, pockets of juicy blueberries, and a tangy-sweet cream cheese frosting that ties it all together. I love how the tartness of the lemon lifts the cake and how the blueberries burst with color and flavor in every bite.
It’s a wonderful cake to bake for a weekend gathering or a special occasion when you want something that looks impressive but is genuinely easy to make. The layers are forgiving, the frosting comes together in minutes, and a short chill makes slicing clean and satisfying.
Ingredients
- 3 cup All-purpose flour
- 1 3/4 cup Granulated sugar
- 2 tsp Baking powder
- 1/2 tsp Baking soda
- 1/2 tsp Salt (for batter)
- 1 cup Unsalted butter, softened
- 3 pieces Large eggs
- 1 cup Buttermilk
- 2 pieces Lemons (zest and juice)
- 2 tsp Vanilla extract
- 2 cup Fresh blueberries
- 8 oz Cream cheese, softened
- 1/2 cup Unsalted butter (for frosting), softened
- 3 1/2 cup Powdered sugar
- 1/4 tsp Salt (for frosting)
- 1/2 cup Blueberries (for garnish)
Instructions
-
Preheat the oven to 350°F. Grease and line two 8-inch round cake pans with parchment; lightly flour the pans and tap out excess.
-
In a medium bowl whisk together the flour, baking powder, baking soda, and salt. Set aside.
-
In a large bowl or stand mixer, cream the softened butter and granulated sugar until light and fluffy, about 3–4 minutes.
-
Add the eggs one at a time, beating well after each. Stir in the lemon zest from the 2 lemons and the vanilla extract.
-
Alternate adding the dry ingredients and the buttermilk to the butter mixture, beginning and ending with the dry ingredients; mix until just combined. Stir in the lemon juice (about 2–3 tbsp) from the lemons.
-
Toss the blueberries with a tablespoon of flour to prevent sinking, then gently fold them into the batter.
-
Divide the batter evenly between the prepared pans and smooth the tops. Bake 25–30 minutes, until a toothpick comes out clean and the tops spring back gently.
-
Let the cakes cool in the pans 10 minutes, then turn out onto wire racks to cool completely before frosting.
-
Make the frosting: beat the cream cheese and softened butter together until smooth. Gradually add the powdered sugar, then mix in the salt and a teaspoon of lemon zest and 1 tbsp lemon juice; beat until fluffy and spreadable.
-
If the cake tops have domed, level them with a serrated knife. Place one layer on your serving plate, spread a generous layer of frosting, then top with the second cake layer.
-
Crumb-coat the cake with a thin layer of frosting and chill 20 minutes, then finish by applying a smooth final coat. Garnish with the reserved blueberries and a little extra lemon zest.
-
Chill the cake 30 minutes to set the frosting for cleaner slices. Slice with a sharp knife wiped between cuts and serve at room temperature.
Tips & Notes
- Room-temperature eggs and butter give a silkier batter and better rise—take them out 30–60 minutes before baking.
- Tossing blueberries in a little flour keeps them suspended in the batter instead of sinking to the bottom.
- If your frosting feels too soft, chill it briefly and then re-whip to regain structure before finishing the cake.
- For even layers, weigh the pans of batter or use a kitchen scale to divide the batter exactly.
- You can use frozen blueberries without thawing—add them straight from frozen and toss in flour to prevent color bleed.
