Preheat your oven to 350 degrees. Lightly grease an 8-inch springform pan and line the bottom with parchment paper. Wrap the outside of the pan with a double layer of heavy-duty aluminum foil to prevent water from leaking in during the water bath.
02 -
In a food processor, pulse the fresh blueberries and room-temperature cream cheese together. Transfer the mixture to a mixing bowl.
03 -
Add the sugar and flour to the blueberry cream cheese mixture and beat until smooth and creamy. Mix in the vanilla extract.
04 -
Add the eggs one at a time, mixing after each addition just to combine. Do not overmix. Then mix in the sour cream and heavy cream.
05 -
Pour the cheesecake batter into the prepared springform pan and smooth the top. Place the pan in a roasting pan and pour boiling water into the roasting pan halfway up the sides of the springform pan, being careful not to get any water on the batter. Bake for 40 to 45 minutes until the center is set.
06 -
Remove the springform pan from the water bath. Run a thin knife around the edges of the cheesecake and allow it to cool to room temperature. Then place in the refrigerator for a few hours or overnight to cool completely.

Preheat your oven to 350 degrees. Butter and lightly flour two 8-inch round cake pans and line the bottoms with parchment paper circles.
08 -
Sift together 2 cups flour, cornstarch, baking powder, and salt. Set aside.
09 -
Stir together milk and lemon juice and set aside to curdle - this creates a buttermilk-like ingredient that helps the cake stay moist.
10 -
Beat the butter and sugar on medium-high speed until pale and fluffy, about 4 minutes.
11 -
With the mixer running on low, add the eggs one at a time and mix after each addition.
12 -
Add the vanilla extract and lemon zest and mix until combined.
13 -
Add the ingredients in this order, mixing to combine after each addition but not overmixing: 1/3 of the flour mixture, then half of the milk mixture, then 1/3 of the flour mixture, then the remaining milk mixture, and finally the remaining flour mixture.
14 -
In a small bowl, gently toss the blueberries with 3 to 4 teaspoons of flour to coat them - this helps prevent them from sinking. Gently fold the floured blueberries into the batter, being careful not to crush the berries.
15 -
Divide the batter evenly between the two pans and smooth the tops. Bake for 30 to 35 minutes until a toothpick inserted in the center comes out clean.
16 -
Cool the cakes in the pans for 10 to 15 minutes, then turn out onto wire racks to finish cooling completely.
17 -
Mix the softened butter and cream cheese on medium speed until no lumps remain. Be careful not to overmix before adding the sugar or the frosting may become runny.
18 -
Add the vanilla extract, salt, and lemon zest and mix until combined.
19 -
Gradually add the powdered sugar until you reach your desired sweetness and thickness. Scrape down the sides of the bowl and beat until smooth and fluffy.

Place one layer of lemon blueberry cake onto your serving plate. Spread a thin layer of lemon cream cheese frosting on top. Place the cooled blueberry cheesecake layer on top and spread with another thin layer of frosting. Top with the second cake layer and frost the entire cake with the remaining frosting.
21 -
Decorate the top of the cake with fresh lemon wedges and fresh blueberries for a beautiful presentation.
22 -
Refrigerate the assembled cake for at least 45 minutes before cutting. This allows the layers to set so the cake won't fall apart when you slice it.
