Yes! Frozen blueberries work great in this recipe. Do not thaw them before adding to the batter, as they release excess moisture. Toss them in a bit of flour before folding them in to prevent sinking.

How to Make Lemon Blueberry Cake recipe

1. Prepare the Cake Batter

1. Preheat your oven to 350°F (175°C). Grease and line three 8-inch cake pans with parchment paper.
2. In a large bowl, beat together sugar, oil, eggs, and extract until smooth.
3. Add lemon zest, juice, and sour cream, mixing until combined.
4. In another bowl, whisk together flour, baking powder, and salt.
5. Gradually add the dry ingredients to the wet ingredients, alternating with buttermilk, mixing until just combined.
6. Toss blueberries with 2 tablespoons of flour, then gently fold them into the batter.
7. Divide the batter evenly between the pans and sprinkle a few extra blueberries on top.
8. Bake for 20-23 minutes or until a toothpick inserted in the center comes out clean.
9. Let the cakes cool completely before frosting.

2. Make the Mascarpone Frosting

1. Chill your mixing bowl and whisk attachment for 5-10 minutes.
2. Beat the mascarpone cheese on low speed, gradually adding heavy cream.
3. Increase speed and whip until soft peaks form.
4. Add powdered sugar and vanilla extract, then continue whipping until stiff peaks form.

3. Assemble & Decorate

1. Level the cakes by cutting off any domed tops.
2. Place the first cake layer on a serving plate and spread a thin layer of frosting.
3. Add half the lemon curd (if using) on top of the frosting.
4. Repeat with the second cake layer.
5. Place the final cake layer on top, bottom side up for a flat surface.
6. Apply a thin crumb coat of frosting, then spread the final layer evenly.
