- Large eggs – 3. Eggs provide structure and richness to the cake.

- Lemon or vanilla extract – 1 teaspoon (5ml). This enhances the cake's flavor profile with a sweet aroma.
- Light sour cream – ½ cup (118 ml). It contributes moisture and a subtle tang that balances the sweetness.
- All-purpose flour – 2 ½ cups (350 g). This forms the base of the cake, providing structure.
- Baking powder – 3 teaspoons (11.2 g). This leavening agent helps the cake rise and become fluffy.

- All-purpose flour for tossing blueberries – 2 tablespoons (15.6g). This prevents the blueberries from sinking in the batter.
- Heavy whipping cream – 2 ¼ cups (532ml). Cream adds richness and body to the frosting.

How to Make Lemon Blueberry Cake
Step 1: Preheat the oven
Preheat the oven to 350°F. Prepare three 8-inch round baking pans by lining the bottoms with parchment paper and greasing the sides to prevent sticking.
Step 2: Make the batter
In a large mixing bowl, combine the granulated sugar, vegetable oil, eggs, and lemon extract. Beat these ingredients on medium speed until everything is well mixed and creamy.
Step 3: Add flavorings
Add the lemon zest, lemon juice, and sour cream to the mixture. Stir well until fully combined, ensuring the mixture is smooth and well incorporated.
Step 4: Combine dry ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this dry mixture to the batter, alternating with the buttermilk, mixing gently until smooth.
Step 5: Fold in blueberries
Gently fold in the blueberries, taking care not to mash them. This ensures they are evenly distributed throughout the batter to create bursts of flavor in every slice.
Step 6: Bake the cakes
Divide the batter evenly among the prepared pans. Bake in the preheated oven for 20 to 23 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
Step 7: Cool completely
Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. Then transfer them to wire racks to cool completely before frosting.
Step 8: Prepare the frosting
For the frosting, chill your mixing bowl. Beat the cold mascarpone cheese until smooth. Gradually add the heavy whipping cream while mixing, then add the powdered sugar and vanilla extract until stiff peaks form.
Step 9: Assemble the cake
Level the tops of the cakes if necessary. Assemble your cake by layering frosting and lemon curd between the cake layers. Frost the top and sides of the entire cake with the remaining frosting.
Step 10: Decorate
Decorate the cake with additional frosting, lemon slices, and fresh blueberries on top for a beautiful finish.
Step 11: Chill before serving
Refrigerate the assembled cake until ready to serve. This helps the flavors meld together and allows the frosting to set.
Pro Tips from My Kitchen
✓ Use fresh blueberries – Fresh blueberries will give the best flavor and texture. If using frozen, make sure they are thawed and drained to avoid excess moisture.
✓ Measure ingredients accurately – Baking is a science. Use a kitchen scale for the best results, especially when measuring flour and sugar.
✓ Allow cakes to cool – Let the cakes cool completely before frosting. This prevents the frosting from melting and helps maintain its shape.
✓ Adjust lemon flavor to taste – Feel free to add more lemon zest or juice depending on your preference for tartness. The cake can handle the extra acidity.
✓ Chill the frosting – If you find the frosting too soft to spread, refrigerate it for a short time until it firms up slightly before decorating.
