Step-by-Step Instructions
Creating this luscious Lemon Blueberry Cake is a joyous experience. Follow these steps for the best results:
- Preheat and Prepare: Preheat your oven to 350 degrees F. Take three 8-inch round baking pans, line the bottoms with parchment paper, and grease the sides to prevent sticking.
- Mix Wet Ingredients: In a large mixing bowl, combine the granulated sugar, vegetable oil, eggs, and lemon extract. Beat the mixture on medium speed until everything is well blended and creamy.
- Add Lemon Flavor: Zest and juice the lemons, adding both to your batter alongside the light sour cream. Beat until all ingredients are integrated nicely.
- Incorporate Dry Ingredients: In a separate bowl, mix together the all-purpose flour, baking powder, and salt. Gradually add the dry mix to the wet batter, alternating with buttermilk, blending until just combined. Avoid overmixing.
- Prepare the Blueberries: To keep your blueberries from sinking, toss them with the 2 tablespoons of flour. Gently fold them into your batter, being careful not to crush them.
- Bake the Cake: Divide the batter evenly between the prepared pans. Bake for 20-23 minutes, or until a toothpick inserted into the center comes out clean. Once done, allow the cakes to cool in the pans for a few minutes before transferring them to a wire rack.
- Make the Frosting: For the frosting, chill your mixing bowl and whisk. Begin by beating the cold mascarpone cheese on medium-low speed. Gradually mix in the heavy cream until soft peaks form. Add powdered sugar and vanilla extract, and then increase speed to high until you have stiff peaks.
- Assemble the Cake: Trim the tops of the cooled cakes if necessary for even layers. Layer the cakes, adding frosting and a spread of lemon curd between each layer, repeating until all layers are assembled.
- Final Frosting: Frost the top and sides of the assembled cake, creating a textured look if desired. Enhance the presentation by garnishing with fresh lemon slices and blueberries.
- Chill and Serve: Refrigerate the cake for at least 30 minutes before serving to allow the flavors to meld and the frosting to set.

Keeping Your Cake Fresh: Storage and Reheating
To prolong the life of your cake while maintaining its freshness, store it in an airtight container in the refrigerator. This Lemon Blueberry Cake can typically last up to 4-5 days when stored correctly. If you want to keep it longer, you can freeze individual slices. Wrap each piece tightly in plastic wrap and then foil to prevent freezer burn. Thaw in the refrigerator for a few hours before serving.
Reheating is straightforward. If you prefer a warm slice, simply pop it in the microwave for about 10-15 seconds until it’s heated through. Just be careful not to overheat it, as this can cause the frosting to melt.
Tips for Success When Making This Cake
Here are some practical tips to ensure your cake turns out beautifully:
- Don’t Overmix: When combining your dry and wet ingredients, mix until just combined to keep the cake tender.
- Room Temperature Ingredients: Using room temperature eggs and sour cream helps create a smooth batter and ensures even baking.
- Check Oven Temperature: Always use an oven thermometer to ensure your oven’s temperature is accurate as baking is a science.
- Fresh Ingredients: Use fresh blueberries for the best flavor and moisture; avoid frozen blueberries as they can add excess moisture.
- Cooling Time Matters: Allow cakes to cool completely before frosting to prevent melting your beautiful mascarpone frosting.
