Step 2: Mix Wet Ingredients
In a large bowl, beat together the following until combined:
1. Granulated sugar,
2. Vegetable oil,
3. Eggs,
4. Lemon extract.
Beat until slightly lighter in color, about two minutes.
Step 3: Add Zest and Sour Cream
Add in the zest from the lemons, their juice, and light sour cream. Mix until fully incorporated.
Step 4: Combine Dry Ingredients
In another bowl, whisk together:
1. All-purpose flour,
2. Baking powder,
3. Salt.
Gradually add half of this mixture to the wet ingredients while mixing on low speed, also adding half of the buttermilk.
Step 5: Finish Batter Mixing
Add in the remaining dry ingredients and buttermilk; mix until just combined. Toss fresh blueberries with two tablespoons of flour, then gently fold them into your batter, saving a few for topping later.
Step 6: Bake the Cakes
Evenly divide your batter into prepared pans. Top with remaining blueberries before placing them in the oven. Bake for about 20-23 minutes, rotating halfway through baking time. Check doneness using a toothpick.
Step 7: Cool the Cakes
Once baked, let your cakes cool completely before frosting them.
Step 8: Prepare Frosting
Chill your mixing bowl and whisk in the freezer for about five to ten minutes. Beat cold mascarpone on medium-low speed while slowly adding heavy cream until it loosens up.
Step 9: Whip Cream
Increase speed to high; whip until soft peaks form. Add powdered sugar and vanilla extract; continue beating until stiff peaks form.
Step 10: Assemble Your Cake
Level each cake layer if necessary. Start by placing one layer on a cake board; pipe or spread mascarpone frosting over it, followed by lemon curd. Repeat this process with a second layer before adding the final layer on top.
Step 11: Frost Entire Cake
Apply a crumb coat first to seal in crumbs before frosting fully with remaining mascarpone frosting. Smooth as desired.
Step 12: Decorate
Finish off by decorating with leftover frosting, lemon slices, and additional blueberries for an eye-catching look!
Now you’re ready to serve this delightful Lemon Blueberry Cake at your next event!
