🍋 Lemon Blueberry Layer Cake 🍰
A stunning tall layer cake with tender lemon-scented sponge, silky whipped cream, and generous layers of bright homemade lemon curd, finished with a glossy lemon drizzle, fresh blueberries, lemon slices, and mint.
Ingredients (for a 4-layer 8-inch cake, serves 12)
Lemon Sponge Cake:
• 2½ cups (300g) all-purpose flour
• 2½ tsp baking powder
• ½ tsp salt
• 1 cup (226g) unsalted butter, softened
• 2 cups (400g) granulated sugar
• 4 large eggs, room temperature
• 1 tbsp lemon zest (from 2 lemons)
• 1 tsp vanilla extract
• 1 cup (240ml) whole milk
• ⅓ cup (80ml) fresh lemon juice
Homemade Lemon Curd:
• 4 large egg yolks
• ¾ cup (150g) sugar
• ⅓ cup fresh lemon juice (about 2–3 lemons)
• 1 tbsp lemon zest
• ½ cup (113g) unsalted butter, cubed
• Pinch of salt
Whipped Cream Filling:
• 3 cups (720ml) heavy whipping cream, cold
• ⅓ cup (40g) powdered sugar
• 2 tsp vanilla extract
Assembly & Topping:
• Extra lemon curd or glaze (thin some curd with a little warm water or juice)
• Fresh blueberries
• Lemon slices
• Fresh mint leaves
• Powdered sugar for dusting
Instructions
1 Make lemon curd (can be done ahead): Whisk yolks, sugar, lemon juice, zest, and salt in a heatproof bowl. Place over simmering water (double boiler) and cook, stirring constantly, until thickened (about 8–10 minutes, 170–180°F). Remove from heat, stir in butter until smooth. Strain if desired, cover with plastic wrap touching the surface, and chill until cold.
2 Bake the cake layers: Preheat oven to 350°F (175°C). Grease and line four 8-inch pans (or bake in batches). Cream butter and sugar until light. Add eggs one at a time, then zest and vanilla. Alternate adding dry ingredients with milk and lemon juice. Divide batter evenly and bake 20–25 minutes until a toothpick comes out clean. Cool completely.
3 Whip the cream: Beat cold cream, powdered sugar, and vanilla to stiff peaks. Keep chilled.
4 Assemble: Place first cake layer on a plate or stand. Spread a thin layer of whipped cream, then a generous layer of lemon curd. Repeat with remaining layers. Cover the entire cake with whipped cream for a naked/semi-naked look. Drizzle lemon curd glaze over the top and let it drip down the sides. Decorate with blueberries, lemon slices, mint, and a final dusting of powdered sugar.
5 Chill for at least 1–2 hours before slicing so the layers set.
Pro tip: Brush each cake layer with a simple lemon syrup (lemon juice + sugar) for extra moisture and flavor.
I had a bunch of fresh lemons and blueberries and decided to go all out on this bright, summery layer cake. I baked the tender lemon sponges from scratch, cooked a silky batch of homemade lemon curd, and whipped up clouds of vanilla cream. Stacking it all together and finishing with that glossy drizzle, juicy berries, and mint made it look bakery-worthy. The first slice was pure sunshine — tangy, sweet, creamy, and incredibly fresh.
