Can I use frozen blueberries instead of fresh ones?

Yes, frozen blueberries are an acceptable substitute when fresh berries are out of season. Do not thaw them before adding to the batter, as this causes the juices to run and turn the sponge grey. Toss them in the flour mixture while frozen and bake immediately.

Why did my cake layers sink in the center?

Sunken centers usually occur when the oven door is opened too early, causing a sudden temperature drop before the structure has set. It can also happen if you use expired baking powder or baking soda, which weakens the gas expansion. Always verify the freshness dates on your chemical leaveners before starting.

How do I store leftovers safely?

Store the assembled cake in an airtight container in the refrigerator for up to 4 days. Because of the fresh fruit and dairy-based icing, leaving it at room temperature will cause rapid spoilage. Bring individual slices to room temperature for 15 minutes before serving to soften the butter fats.

Can I freeze the cake layers for assembly later?

Yes, you can freeze the uniced sponge layers for up to 3 months. Wrap each cooled layer tightly in two layers of plastic wrap and store them on a flat surface in the freezer. Thaw the layers in the refrigerator overnight before applying the freshly made frosting.

Why is my whipped frosting grainy or lumpy?

Grainy frosting occurs when the cream cheese is beaten while it is still too cold and firm, preventing it from blending smoothly. It can also happen if you use coarse granulated sugar instead of finely sifted powdered sugar. Always beat the cream cheese alone on low speed until smooth before folding in the cream.

Can I bake this recipe in a 9-inch pan instead?

You can bake this batter in two 9-inch pans, but you must adjust the baking time accordingly. The thinner layers will bake faster, requiring approximately 25 to 30 minutes in the oven. Watch for the same visual cues and verify with a toothpick to prevent overbaking.

Instructions

Preheat the oven. Heat to 180°C (350°F) and grease three 6-inch cake pans, lining the bottoms with parchment paper.
Prepare dry components. Sift the flour, cornstarch, baking soda, powder, and salt together, then reserve one tablespoon of the mixture for the berries.
Cream the base. Beat the butter, oil, sugar, and zest for 3 minutes until pale and aerated.
Incorporate liquids. Add eggs one at a time, then mix in the buttermilk and lemon juice until integrated.
Fold in dry ingredients. Gently combine the flour mixture into the wet ingredients, folding only until no streaks remain.
Coat and add fruit. Toss the blueberries in the reserved tablespoon of flour and fold them into the batter with three swift strokes.
Bake the layers. Divide batter into pans and bake for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean.
Cool the cake. Let the pans rest for 10 minutes before inverting the sponges onto a wire rack to cool completely.
Whip the frosting. Beat the cold cream cheese until smooth, then fold in whipped heavy cream, powdered sugar, and vanilla.
Assemble and chill. Level the cooled layers, frost between each and over the top, and chill for 30 minutes before serving.

Notes

Use a digital kitchen scale for all measurements to ensure the delicate starch-to-flour ratio remains accurate.
Keep your cream cheese and heavy cream refrigerated until the exact moment of whipping to ensure structural stability.
Slicing the cake with a warm, clean knife will provide sharp, professional edges that showcase the interior layers.
Ensure the lemon zest is rubbed directly into the sugar to release and distribute the essential citrus oils effectively.
