Essential Equipment:

• Three 8-inch round baking pans
• Parchment paper
• Mixing bowls
• Electric mixer or stand mixer
• Spatula
• Toothpicks
• Bake even stripes (optional)

Ingredients:

• For the Cake:
  • 2 cups (380g) granulated sugar
  • ½ cup (118ml) vegetable oil
  • 3 large eggs
  • 2 lemons, zested and juiced (to yield ¼ cup juice)
  • 1 teaspoon (5ml) lemon extract
  • ½ cup (118ml) light sour cream
  • 2 ½ cups (350g) all-purpose flour
  • 3 teaspoons (11.2g) baking powder
  • 1 teaspoon (5g) salt
  • 1 cup (236ml) buttermilk
  • 9 ounces fresh blueberries, washed and dried
  • 2 tablespoons (15.6g) all-purpose flour
• For the Frosting:
  • 2 ¼ cups (532ml) heavy whipping cream
  • 1 cup (130g) powdered sugar
  • 1 teaspoon (5ml) pure vanilla extract
  • 16 ounces mascarpone cheese, cold
  • 1 jar (10 ounces) lemon curd

Step-by-Step Instructions:

1. Prepare the Oven and Pans:
   • Preheat your oven to 350°F.
   • Grease and flour three 8-inch round baking pans. Line the bottoms with parchment paper for easy removal.
   • If you have bake-even strips, soak them in water and wrap them around the pans. This will help the cakes bake more evenly.
2. Make the Cake Batter:
   • In a large mixing bowl, combine the sugar, vegetable oil, eggs, and lemon extract.
   • Beat on medium speed for about 2 minutes, until the mixture is light and fluffy.
   • Zest the lemons directly into the batter and then juice them to get ¼ cup of fresh lemon juice.
   • Add the lemon zest, lemon juice, and sour cream to the batter and beat until well combined.
   • In a separate bowl, whisk together the flour, baking powder, and salt.
   • Gradually add the dry ingredients to the wet ¹ ingredients, alternating with the ² buttermilk, and mix until just combined. Be careful not to overmix.  
   • Toss the blueberries with 2 tablespoons of flour to prevent them from sinking to the bottom of the cake.
   • Gently fold the blueberries into the batter, reserving a small handful to sprinkle on top.
3. Bake the Cakes:
   • Divide the batter evenly among the prepared pans.
   • Sprinkle the remaining blueberries on top of the batter in each pan.
   • Bake for 20-23 minutes, or until a toothpick inserted into the center comes out clean.
   • Rotate the pans halfway through baking to ensure even cooking.
   • Once baked, remove the cakes from the oven and let them cool completely in the pans before frosting.
4. Make the Lemon Mascarpone Frosting:
   • In a large mixing bowl, beat the heavy whipping cream with an electric mixer until stiff peaks form.
   • Gradually add the powdered sugar and vanilla extract, beating until smooth and fluffy.
   • In a separate bowl, beat the cold mascarpone cheese until smooth and creamy.
   • Gently fold the whipped cream into the mascarpone cheese until combined.
   • Fold in the lemon curd until evenly distributed.
5. Assemble the Cake:
   • Once the cakes are completely cool, level the tops with a serrated knife if needed.
   • Place one cake layer on a serving plate and top with a layer of frosting.
   • Repeat with the remaining cake layers and frosting.
   • Frost the entire cake with the remaining frosting.
   • Decorate as desired with fresh blueberries, lemon zest, or lemon slices.

Troubleshooting:

• Dense or Soggy Cake: Make sure your leavening agents (baking powder) are fresh. Also, avoid overmixing the batter, as this can lead to a tough cake.
• Runny Frosting: If your frosting is too runny, chill it in the refrigerator for 15-20 minutes to firm up. You can also add more powdered sugar, one tablespoon at a time, until you reach the desired consistency.

Tips and Variations:

• You can use other berries, such as raspberries or strawberries, instead of blueberries.
• For a more intense lemon flavor, add a tablespoon of lemon zest to the batter.
• You can also make cupcakes instead of a layer cake.

Serving Suggestions:

• Serve this Lemon Blueberry Cake chilled. It’s a refreshing and satisfying treat for any occasion.
• It pairs beautifully with a cup of coffee or tea.
