Ingredients You’ll Need
Using high-quality, room-temperature ingredients is the first step to creating the perfect lemon blueberry layer cake. Precision in measurement, especially with a digital kitchen scale, will yield the best results.
For the Lemon Blueberry Cake Layers:
- All-Purpose Flour: 2 1/2 cups (300g), plus 1 tbsp for tossing the blueberries. This provides the main structure for our cake.
- Baking Powder: 2 1/2 tsp (10g) to give the cake a beautiful lift, making it light and airy.
- Salt: 1/2 tsp to balance the sweetness and enhance the other flavors.
- Unsalted Butter: 1 cup (227g), softened to room temperature. This is crucial for a smooth, properly emulsified batter.
- Granulated Sugar: 1 3/4 cups (350g) provides sweetness, moisture, and a tender crumb.
- Large Eggs: 4 large eggs, at room temperature, to bind the ingredients and add richness.
- Lemon Zest & Juice: 1 tbsp finely grated lemon zest (from 2 large lemons) and 1/4 cup (60ml) fresh lemon juice for that signature bright, citrus flavor.
- Vanilla Extract: 1 tsp to add warmth and depth to the flavor profile.
- Buttermilk: 1 cup (240ml), at room temperature. The acidity in buttermilk creates an exceptionally tender and moist cake.
- Blueberries: 1 1/2 cups (220g) of fresh or frozen blueberries.
For the Lemon Cream Cheese Frosting:
- Cream Cheese: 16 oz (452g) of full-fat, block-style cream cheese, softened. Avoid the whipped tub variety for the best frosting consistency.
- Unsalted Butter: 1 cup (227g), softened to room temperature.
- Powdered Sugar: 4 cups (480g), sifted to ensure a silky-smooth, lump-free frosting.
- Fresh Lemon Juice & Zest: 1/4 cup (60ml) of juice and 1 tbsp of zest for a tangy kick.
- Vanilla Extract: 1 tsp to complement the lemon flavor.
- Salt: A small pinch to cut through the sweetness.
For Garnish (Optional):
- 1/2 cup fresh blueberries
- 1 lemon, for zesting or cutting into thin decorative slices

Step-by-Step Instructions
Follow these detailed steps to create a flawless layer cake from scratch. Read through all the steps before beginning.
Preparing the Cake Batter
- Step 1: Prep Oven and Pans. First, position a rack in the center of your oven and preheat to 350°F (175°C). Next, generously grease and flour three 8-inch round cake pans. For guaranteed easy release, line the bottom of each pan with a circle of parchment paper.
- Step 2: Combine Dry Ingredients. In a medium bowl, whisk together the 2 1/2 cups (300g) of all-purpose flour, baking powder, and salt. Whisking for 30 seconds ensures the leavening agents are evenly distributed, which helps the cakes rise evenly. Set this bowl aside.
- Step 3: Prepare the Blueberries. In a separate small bowl, gently toss the fresh or frozen blueberries with 1 tablespoon of flour until lightly coated. This simple but crucial step helps suspend the berries within the batter, preventing them from sinking to the bottom during baking.
- Step 4: Cream Butter and Sugar. In the large bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), beat the room temperature butter and granulated sugar on medium-high speed for 3–5 minutes. The mixture should become very light, pale, and fluffy. This process incorporates air, which is key to a light cake texture.
- Step 5: Add Eggs and Flavorings. Reduce the mixer speed to medium and add the room temperature eggs one at a time, allowing each egg to fully incorporate before adding the next. Scrape down the sides and bottom of the bowl with a spatula as needed. Mix in the lemon zest, fresh lemon juice, and vanilla extract until just combined.
- Step 6: Alternate Dry and Wet Ingredients. With the mixer on its lowest speed, add the dry ingredient mixture in three additions, alternating with the buttermilk in two additions. Start and end with the dry ingredients (Flour, Buttermilk, Flour, Buttermilk, Flour). Mix only until the last streaks of flour have disappeared. Be careful not to overmix, as this can lead to a dense cake.
- Step 7: Fold in Blueberries. Remove the bowl from the mixer and use a rubber spatula to give the batter a final gentle fold. Add the flour-coated blueberries and fold them in carefully until they are evenly distributed.
Baking and Cooling the Cakes
- Step 8: Divide Batter and Bake. Divide the batter evenly among the three prepared cake pans. For perfectly even layers, use a kitchen scale to weigh the batter in each pan. Use your spatula to spread the batter into a smooth, even layer.
- Step 9: Bake Until Golden. Bake for 25–30 minutes. The cakes are done when a wooden toothpick or cake tester inserted into the center comes out with a few moist crumbs attached. The tops will be golden brown and should spring back when lightly touched.
- Step 10: Cool the Cakes Completely. Let the cakes cool in their pans on a wire rack for 15 minutes. Then, carefully run a thin knife around the edges and invert the cakes onto the wire rack. Peel off the parchment paper and allow them to cool completely to room temperature before attempting to frost. Warm cakes will melt the frosting!
Making the Lemon Cream Cheese Frosting
- Step 11: Beat Cream Cheese and Butter. In a large bowl, use a hand or stand mixer to beat the softened cream cheese and butter together on medium-high speed for about 2 minutes, until the mixture is completely smooth, creamy, and free of lumps.
- Step 12: Add Remaining Ingredients. Reduce the mixer speed to low and gradually add the sifted powdered sugar until it’s incorporated. Then, add the lemon juice, lemon zest, vanilla extract, and a pinch of salt. Increase the speed to high and beat for an additional 2–3 minutes until the frosting is light, fluffy, and holds its shape beautifully.
Assembling Your Lemon Blueberry Layer Cake
- Step 13: Level the Cakes. If your cake layers have slightly domed tops, use a large serrated knife to carefully trim them flat. This creates a stable, even surface for stacking and decorating.
- Step 14: Assemble the First Layer. Place one cake layer onto your serving plate or cake stand. Scoop about 1 cup of the lemon cream cheese frosting on top and use an offset spatula to spread it evenly right to the edges.
- Step 15: Add the Second and Third Layers. Carefully place the second cake layer on top and repeat with another cup of frosting. Place the final cake layer on top, placing it bottom-side up for a perfectly flat top surface.
- Step 16: Apply a Crumb Coat. Apply a very thin layer of frosting over the top and sides of the entire cake. This “crumb coat” traps any loose crumbs. Chill the cake in the refrigerator for at least 30 minutes (or in the freezer for 15 minutes) until this layer is firm to the touch.
- Step 17: Frost and Decorate. Once the crumb coat is set, apply the remaining frosting generously over the top and sides. Use an offset spatula or bench scraper to create a smooth or beautifully textured finish. Garnish with fresh blueberries and extra lemon zest or thin lemon slices just before serving.
Baking Tips, Variations & Substitutions
Pro Tips for the Best Lemon Blueberry Layer Cake
- Room Temperature is Non-Negotiable: For the smoothest batter and frosting, ensure your butter, eggs, buttermilk, and cream cheese are all genuinely at room temperature. This allows them to emulsify properly, creating a lighter, more uniform texture.
- Don’t Overmix the Batter: After you start adding the flour mixture, mix on the lowest speed and only until it’s *just* combined. Overmixing develops gluten, which can result in a dense, tough, or dry cake.
- The Crumb Coat is a Game-Changer: Don’t skip the crumb coat and chilling step! This professional secret is the key to a beautifully clean, crumb-free final coat of frosting. It’s a small step that makes a huge difference in the final appearance.
- Use Fresh Lemon Juice: For the brightest and most authentic citrus flavor, always use freshly squeezed lemon juice instead of the bottled variety. The flavor is far superior and makes this cake shine.
Easy Variations You Can Try
- Add a Lemon Curd Filling: For an extra pop of tangy flavor, spread a thin layer of your favorite lemon curd between the cake layers before adding the frosting.
- Try Different Berries: This cake is also delicious with raspberries or chopped strawberries instead of blueberries. You can also use a mix of berries for a “mixed berry” version.
- Make it a Loaf Cake: You can adapt this recipe to make two 9×5 inch loaf cakes. Start checking for doneness around the 45-50 minute mark.
- Add a Hint of Spice: A pinch of cardamom or ground ginger in the dry ingredients can add a lovely, warm complexity that pairs beautifully with lemon and blueberry.
How to Serve & Store Your Lemon Blueberry Layer Cake
For the best flavor and texture, serve this cake chilled or at a cool room temperature. The tangy frosting and bright lemon notes are perfectly refreshing. It pairs wonderfully with a cup of hot tea, coffee, or a tall glass of cold milk. Before serving, you can add a final flourish of fresh lemon zest for an extra burst of aroma.
To store your cake, cover it tightly with a cake dome or plastic wrap and refrigerate. Due to the cream cheese frosting, it must be kept chilled. It will stay fresh and delicious for up to 5 days. For freezing, you have two options. You can freeze individual unfrosted cake layers by wrapping them tightly in two layers of plastic wrap and then a layer of foil for up to 3 months. Thaw overnight in the refrigerator before frosting. Alternatively, you can freeze the fully assembled and frosted cake. To do this, place the cake uncovered in the freezer for about an hour to firm up the frosting, then wrap it tightly in plastic wrap and foil. It will keep for up to 1 month. Thaw overnight in the refrigerator before serving.
Watch: How to Make It
Frequently Asked Questions
Can I use frozen blueberries instead of fresh?
Yes, absolutely. Do not thaw frozen blueberries before use. Tossing them in flour while still frozen is key. Gently fold them into the batter at the very last moment to prevent their color from bleeding and turning your batter purple.
Can I freeze this Lemon Blueberry Layer Cake?
Yes, this cake freezes exceptionally well. For best results, freeze the individual, cooled cake layers. Wrap them tightly in two layers of plastic wrap and one layer of aluminum foil. They can be frozen for up to 3 months. Thaw at room temperature before frosting and assembling.
Can I reduce the sugar in this recipe?
We don’t highly recommend reducing the sugar. Sugar does more than add sweetness; it’s crucial for the cake’s moisture, tenderness, and structure. Reducing it significantly will likely result in a drier, less tender cake. If you must, you can reduce it by about 1/4 cup (50g) in the cake batter without dramatic changes.
My cream cheese frosting is too thin. How can I fix it?
This is a common issue, often caused by overly soft butter/cream cheese or a warm kitchen. The quickest fix is to place the entire bowl of frosting in the refrigerator for 20-30 minutes to firm up before re-whipping. If it’s still too thin, you can beat in more sifted powdered sugar, 1/4 cup at a time, until it reaches your desired consistency.
