Why You’ll Love This Recipe
I love how this cake balances tart and sweet flavors so perfectly. The lemon adds a refreshing citrus kick while the blueberries bring natural sweetness and bursts of juice in every bite.

ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
For the cake:
2 ½ cups all-purpose flour
2 ½ teaspoons baking powder
½ teaspoon salt
1 cup unsalted butter, softened
1 ¾ cups granulated sugar
4 large eggs
1 tablespoon lemon zest
¼ cup fresh lemon juice
1 teaspoon vanilla extract
1 cup whole milk
1 ½ cups fresh or frozen blueberries (tossed in 1 tablespoon flour)
For the frosting:
1 cup unsalted butter, softened
4 cups powdered sugar
2 tablespoons lemon juice
1 teaspoon lemon zest
2–3 tablespoons heavy cream
1 teaspoon vanilla extract
directions
I start by preheating the oven to 350°F (175°C) and greasing two 9-inch round cake pans. I line them with parchment paper for easy removal.
In a bowl, I whisk together flour, baking powder, and salt. In another large bowl, I cream the butter and sugar until light and fluffy. I add the eggs one at a time, mixing well after each addition, then stir in lemon zest, lemon juice, and vanilla.
I alternate adding the dry ingredients and milk into the batter, beginning and ending with the dry mixture. I gently fold in the blueberries.
I divide the batter evenly between the pans and bake for 25–30 minutes, until a toothpick inserted in the center comes out clean. I let the cakes cool completely before assembling.
For the frosting, I beat the butter until smooth, then gradually add powdered sugar. I mix in lemon juice, zest, vanilla, and enough cream to reach a smooth, spreadable consistency.
I layer the cakes with frosting in between, then frost the top and sides. I like to decorate with extra blueberries and lemon slices.
Servings and timing
Servings: 10–12 slices Prep time: 25 minutes Bake time: 25–30 minutes Total time: about 1 hour 15 minutes
Variations
I sometimes swap blueberries with raspberries for a slightly tangier flavor. If I want a richer texture, I add a thin layer of lemon curd between the cake layers. For a lighter version, I use whipped cream frosting instead of buttercream.
storage/reheating
I store the cake in an airtight container in the refrigerator for up to 4 days. Before serving, I let it sit at room temperature for about 20 minutes so the texture softens. I don’t usually reheat it, but I enjoy it slightly chilled or at room temperature.
FAQs
Can I use frozen blueberries?
I use frozen blueberries often. I don’t thaw them before adding, and I toss them in flour to prevent sinking.
How do I keep the cake moist?
I make sure not to overbake it and always measure ingredients carefully. The milk and butter help keep it soft.
Can I make this cake ahead of time?
I bake the layers a day in advance and store them wrapped. I frost the cake the next day for best freshness.
What frosting works best besides buttercream?
I sometimes use cream cheese frosting or whipped cream frosting for a lighter taste.
Can I make this into cupcakes?
I use the same batter and bake in cupcake liners for about 18–20 minutes. It works perfectly.

I enjoy making this lemon blueberry layer cake whenever I want something fresh, vibrant, and satisfying. The flavors feel bright and comforting at the same time, and the soft texture makes every slice enjoyable. It’s a reliable recipe that always impresses when I serve it.
