Can I use frozen blackberries for this Blackberry Vanilla Cake?

Yes, you can use frozen berries if fresh ones are not available in your local stores. Do not thaw them before adding them to the batter, as this will bleed purple juice throughout the white cake. Toss them in flour while still frozen and bake for an extra two to three minutes to account for the cold fruit.

How should I store the leftover cake?

Store any leftover slices in the refrigerator to keep the fresh blackberry curd from spoiling. Press a piece of plastic wrap directly against the exposed cut edges to keep them from drying out in the cold air. Bring the slices to room temperature for twenty minutes before eating so the butter in the cake softens up.

Can I make this cake ahead of time?

You can easily bake the cake layers a day in advance to save time on the day of your event. Wrap the cooled layers tightly in plastic wrap and keep them in the refrigerator overnight. This actually makes them much easier to slice and assemble because the crumb becomes firmer and less prone to tearing.

What can I use if I do not have sour cream?

Plain whole-milk Greek yogurt makes an excellent substitute for sour cream in this recipe. It provides the same acidity and fat content needed to keep the cake crumb incredibly tender and moist. Avoid using fat-free or low-fat options, as they will make the finished cake taste dry and heavy.

Why did my blackberries sink to the bottom of the pan?

Berries sink when they are too wet or if the cake batter is mixed too thin to support them. Coating them in a tablespoon of flour helps them cling to the batter and stay suspended during baking. Be sure to scatter them on top of the batter in the pan rather than stirring them in.

Can I freeze the assembled cake?

It is best to freeze the un-iced cake layers rather than the fully assembled cake with the curd filling. Wrap each individual cooled layer tightly in plastic wrap and heavy foil, then freeze for up to three months. Thaw them in the refrigerator overnight before frosting and assembling with fresh curd.

How do I make my frosting completely smooth?

Beat your buttercream frosting on low speed for about ten minutes after incorporating the powdered sugar. This slow mixing knocks out any large air pockets, leaving you with a silky texture that spreads like a dream. Using room-temperature butter is critical for this process to succeed.

Instructions

Prepare the pans. Preheat oven to 350F and grease three six-inch pans, lining the bottoms with parchment paper.
Cream butter and sugar. Beat butter and sugar on medium speed for three minutes until the mixture is pale, fluffy, and airy.
Incorporate the eggs. Turn mixer to low and add eggs one at a time, ensuring each is fully blended before adding the next.
Mix dry ingredients. Sift flour, baking powder, and baking soda into a bowl, and whisk milk, sour cream, and vanilla in a separate container.
Combine the batter. Alternate adding the flour mixture and wet ingredients to the creamed butter, mixing on low speed until just combined.
Coat the berries. Toss fresh blackberries with one tablespoon of flour, then fold gently into the batter or scatter across the pans.
Bake the layers. Bake for 28-33 minutes until golden and a toothpick inserted in the center comes out clean.
Whip the frosting. Beat softened butter and vanilla bean seeds until creamy, then gradually add powdered sugar and milk until smooth.
Assemble the cake. Layer the cooled cakes with frosting and blackberry curd, finishing with a thin crumb coat and final layer of frosting.

Notes

Ensure all dairy and eggs are at room temperature to prevent the batter from curdling.
Toss fresh berries in flour before adding to the batter to prevent them from sinking to the bottom.
Use a kitchen scale to ensure each pan contains the same amount of batter for even baking.
Chill the assembled cake for thirty minutes before slicing to keep the layers stable and the curd clean.
Clean your knife in hot water between each cut to prevent colors from smudging.
