Ingredients
This cake relies on a handful of high‑quality staples: butter for richness, fresh lemon for brightness, and plump blueberries for natural sweetness. The cake batter stays tender thanks to a gentle fold of flour and baking powder, while the buttercream blends softened butter, powdered sugar, and lemon zest into a silky frosting that holds the cake together beautifully.
Cake Base
- 1 ½ cups all‑purpose flour
- 2 teaspoons baking powder
- ¼ teaspoon salt
- ¾ cup unsalted butter, softened
- 1 cup granulated sugar
- 3 large eggs, room temperature
- ¼ cup whole milk
- Zest of 2 lemons
- 2 tablespoons fresh lemon juice
Lemon Blueberry Filling
- 1 ½ cups fresh blueberries
- 2 tablespoons granulated sugar
- 1 tablespoon cornstarch
- 1 tablespoon lemon juice
Lemon Buttercream Frosting
- 1 cup unsalted butter, softened
- 3 ½ cups powdered sugar, sifted
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
- Pinch of salt
The flour and baking powder give the cake its lift, while butter creates a tender crumb. Lemon zest and juice infuse the batter with bright flavor that pairs perfectly with the sweet‑tart blueberry filling. The buttercream’s powdered sugar base provides a smooth canvas for the citrus notes, and the added pinch of salt balances the sweetness, ensuring every bite is harmonious.
Step-by-Step Instructions

Preparing the Batter
Begin by preheating your oven to 350°F (175°C)** and greasing a 9‑inch round cake pan. In a medium bowl whisk together 1 ½ cups flour, 2 teaspoons baking powder, and ¼ teaspoon salt. This aerates the dry mix and prevents clumps, ensuring an even rise.
Creaming Butter and Sugar
In a large mixing bowl, beat ¾ cup softened butter with 1 cup granulated sugar on medium speed for 3‑4 minutes until pale and fluffy. This process incorporates air, which is essential for a light cake texture.
Incorporating Eggs and Lemon
Add the 3 large eggs one at a time, beating well after each addition. Then stir in zest of 2 lemons and 2 tablespoons lemon juice. The acidity helps the batter loosen, creating a tender crumb.
Combining Wet and Dry Ingredients
- Mix dry into wet. Add the flour mixture to the butter‑egg mixture in three additions, alternating with ¼ cup milk. Start and end with the flour. This prevents over‑mixing, which could make the cake dense.
- Fold in blueberries. Gently fold 1 ½ cups fresh blueberries with a rubber spatula, being careful not to crush them. The berries will create pockets of juicy flavor throughout the cake.
- Transfer to pan. Pour the batter into the prepared pan, smoothing the top with a spatula. Tap the pan lightly on the counter to release any large air bubbles.
- Bake. Place in the preheated oven and bake for 25‑30 minutes, or until a toothpick inserted into the center comes out clean. The edges should be lightly golden.
- Cool. Allow the cake to cool in the pan for 10 minutes, then turn onto a wire rack to cool completely before frosting. This prevents the frosting from melting.
Making the Lemon Buttercream
While the cake cools, beat 1 cup softened butter on medium speed until creamy. Gradually add 3 ½ cups powdered sugar, one cup at a time, mixing on low to avoid a sugar cloud. Once smooth, blend in 2 tablespoons lemon juice, 1 teaspoon lemon zest, and a pinch of salt. Beat on high for 2 minutes until the frosting is light and fluffy.
Assembling the Cake
If you baked a single layer, simply spread the buttercream over the top. For a two‑layer cake, slice the cake horizontally, place the bottom half on a serving plate, spread a thin layer of frosting, then add the top half. Finish by frosting the sides and top, smoothing with an offset spatula. Garnish with a few extra blueberries and a light dusting of lemon zest for visual appeal.
Tips & Tricks
Perfecting the Recipe
Room‑temperature ingredients. Bring butter, eggs, and milk to room temperature before mixing; this creates a smoother batter and more even rise.
Don’t over‑mix. Stir the flour in just until combined. Over‑mixing develops gluten, which can make the cake tough.
Use fresh berries. Fresh blueberries retain their shape and burst with juice, whereas frozen ones can turn the batter soggy.
Flavor Enhancements
Add a teaspoon of vanilla extract to the batter for depth, or swirl a spoonful of raspberry jam into the frosting for a subtle berry contrast. A pinch of poppy seeds in the batter adds a gentle crunch that pairs nicely with lemon.
Common Mistakes to Avoid
Skipping the cooling step before frosting will cause the buttercream to melt and slide off. Also, avoid opening the oven door too early; sudden temperature drops can cause the cake to sink in the center.
Pro Tips
Use a kitchen scale. Measuring flour by weight (≈180 g) eliminates packing errors and yields consistent results.
Chill the frosting. After mixing, refrigerate the buttercream for 10 minutes before spreading; this prevents it from sliding off a warm cake.
Level the layers. Use a serrated knife or cake leveler to trim any domed tops, ensuring a stable stack.
Store with parchment. Place a sheet of parchment between the cake and frosting when refrigerating to keep the frosting from sticking.
Variations
Ingredient Swaps
Replace blueberries with raspberries or sliced strawberries for a different berry profile. Swap lemon zest for orange zest for a sweeter citrus twist, and use almond flour for a gluten‑free crumb that adds a nutty undertone.
Dietary Adjustments
For a vegan version, use coconut oil instead of butter, plant‑based milk, and aquafaba as an egg substitute. Replace powdered sugar with a fine powdered erythritol for a low‑sugar alternative, and ensure the flour is certified gluten‑free.
Serving Suggestions
Pair each slice with a dollop of whipped coconut cream and a drizzle of honey for extra indulgence. Serve alongside a glass of chilled Prosecco or a bright iced tea to complement the citrus notes.
Storage Info
Leftover Storage
Once sliced, store cake layers in an airtight container or tightly wrapped plastic wrap. Keep in the refrigerator for up to 4 days. For longer keeping, freeze individual slices wrapped in parchment and then foil; they’ll hold for up to 2 months.
Reheating Instructions
Warm a slice in a 300°F (150°C) oven for 8‑10 minutes, uncovered, to revive the crumb and melt the frosting gently. Microwaving on medium for 20‑30 seconds works in a pinch, but the oven method preserves texture best.
