It’s elegant enough for special occasions but simple enough to become your go-to celebration cake.

Pro Tips
- Use room temperature ingredients (eggs, butter, buttermilk) to create a smoother batter that bakes more evenly and produces tender crumb
- Don’t skip the lemon zest in both the cake and frosting — it delivers far more flavor than juice alone and gives that authentic bakery taste
- Simmer your blueberry filling until it’s thick enough to coat the back of a spoon; thin filling will seep between layers and make the cake soggy
- Chill the assembled cake for 30 minutes before the final frosting coat — this “crumb coat” technique locks in stray crumbs and gives you that clean, professional finish
Lemon Blueberry Layer Cake Recipe
Ingredients
Method
- Preheat your oven to 350°F (175°C). Grease three 8-inch round cake pans, line the bottoms with parchment paper rounds, and lightly flour the sides.
- In a medium bowl, whisk together the flour, baking powder, and salt until evenly combined. Set aside.
- In a large mixing bowl, beat the softened butter and 2 cups sugar with an electric mixer on medium-high speed for 3-4 minutes until light and fluffy. Add the eggs one at a time, beating well after each addition. Mix in 1 tablespoon lemon zest and lemon juice.
- With the mixer on low speed, alternate adding the flour mixture and buttermilk in three additions, beginning and ending with flour. Mix just until no streaks remain — do not overmix.
- Divide the batter evenly among the three prepared pans (about 2 cups per pan). Bake for 25-28 minutes, until a toothpick inserted in the center comes out clean and the tops spring back when lightly pressed. Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
- While the layers cool, make the blueberry filling. In a small saucepan, combine 1.5 cups blueberries, 1/3 cup sugar, and cornstarch. Cook over medium heat, stirring frequently, until the berries burst and the mixture thickens to a jam-like consistency, about 8-10 minutes. Remove from heat and stir in the remaining 0.5 cup fresh blueberries. Let cool completely.
- For the frosting, beat the softened cream cheese and 1 cup butter together on medium speed until smooth and creamy, about 2 minutes. Gradually add the powdered sugar, one cup at a time, beating on low speed. Add 2 teaspoons lemon zest and heavy cream, then beat on high for 1-2 minutes until light and fluffy.
- To assemble, place one cake layer on your serving plate. Spread half the blueberry filling over the top, leaving a 1/2-inch border around the edges. Add the second layer and repeat with remaining filling. Top with the third layer.
- Apply a thin crumb coat of frosting over the entire cake to seal in crumbs. Refrigerate for 30 minutes, then frost the cake with the remaining frosting, using a spatula or bench scraper to smooth the sides and top.
- Refrigerate the assembled cake for at least 2 hours before slicing to let the layers set. Remove from the refrigerator 30-60 minutes before serving for the best flavor and texture.
Frequently Asked Questions
Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries work perfectly in the filling. Don’t thaw them first — add them frozen to the saucepan and cook a few extra minutes until the mixture thickens. The filling may be slightly darker in color but tastes just as delicious.
How do I prevent my cake layers from doming in the middle?
Wrap each pan with damp cake strips or strips of wet towel secured with pins before baking. This insulates the edges so they bake at the same rate as the center, creating flat layers that need minimal trimming.
Can I make this cake without buttermilk?
Absolutely. Mix 1 cup of whole milk with 1 tablespoon of fresh lemon juice or white vinegar. Let it sit for 5 minutes until slightly curdled, then use it exactly as you would buttermilk.
How far in advance can I assemble this cake?
Assemble the fully frosted cake up to 24 hours before serving. Store it in the refrigerator, then bring it to room temperature 1-2 hours before slicing for the best texture and flavor.
Storage & Serving
Store this cake covered in the refrigerator for up to 4 days — the cream cheese frosting keeps everything fresh and moist. For longer storage, wrap unfrosted layers tightly in plastic wrap and freeze for up to 3 months. Serve slices at room temperature with fresh berries on the side, a dollop of whipped cream, or simply on its own to let those bright lemon-blueberry flavors shine.
This is the cake that turns any gathering into a celebration — go ahead and bake it this weekend!
