It might seem like a long list, but each ingredient plays its part in building up the flavors, textures, and that amazing color that makes this cake truly unforgettable. Here’s what you’ll want to gather:

Freeze-dried blueberry powder: Adds deep blueberry flavor without extra moisture and enhances the beautiful color.
Butter (softened): Provides richness and tenderness to both the cake and the buttercream.
Organic powdered sugar: Sweetens the buttercream smoothly without gritty texture.
Vanilla extract: Balances and lifts the overall flavor profile.
Fine sea salt: Amplifies sweetness and rounds the flavors perfectly.
Fresh blueberries: Adds bursts of juicy, fresh fruit and makes the compote zingy and delicious.
Lemon zest and juice: Gives a bright, refreshing lift, cutting through the sweetness.
Cake flour: Keeps the crumb tender and delicate, ideal for a soft layer cake.
Baking powder and baking soda: Ensure the cake rises perfectly and stays light.
Eggs (room temperature): Bind the cake batter beautifully and enrich texture.
Lowfat kefir or buttermilk: Adds acidity and moisture, giving that tender crumb signature.
Sugar: Sweetens and helps with browning the cake layers.

How to Make Blueberry Layer Cake with Lemon-Blueberry Filling and Blueberry Buttercream Recipe

Step 1: Prepare the Blueberry Buttercream

The night before assembling your cake, start by making the blueberry buttercream. Beat softened butter, salt, vanilla, and the blueberry powder until smooth and creamy. Slowly incorporate the powdered sugar and continue beating until the mixture is fluffy. Adding a splash of milk or cream helps to achieve the perfect spreading consistency. Storing it overnight allows the blueberry elements to bloom beautifully in the frosting; you will notice the color deepen and the flavor intensify with time.

Step 2: Cook the Blueberry Filling

Next up is the luscious filling. Combine fresh blueberries, sugar, lemon zest, and lemon juice in a small pot, simmering gently until the berries soften and burst, creating a thick, jammy texture. Cool this compote completely before using it between the cake layers so it sets up nicely, adding both tartness and sweetness with a fresh fruity punch.

Step 3: Prepare the Blueberry Cake Batter

Start by pureeing fresh blueberries and simmering them until the mixture thickens substantially, then cool it completely. Preheat your oven and prep your cake pans by buttering and flouring them. Using the reverse creaming method, first blend your butter, sugar, and cake flour with leavening agents until crumbly. Add eggs one at a time, then, with the mixer running, blend in the cooled blueberry reduction, blueberry powder, lemon juice, and kefir to form a smooth batter. Split the batter evenly between pans and bake until the tops spring back gently when touched or a tester comes out clean. Allow your cakes to cool completely before assembly.

Step 4: Assemble the Cake

Now for the fun part! Whip the buttercream thoroughly to ensure color and flavor are perfectly combined. Level the cake layers by slicing off the rounded tops. Pipe a buttercream border on one cake layer to hold the filling in place, spread the blueberry compote inside this ring, then top with the second cake layer upside down. Frost the entire cake with the remaining buttercream, smoothing it evenly for a flawless finish. Use an offset spatula or the back of a spoon for a homemade, elegant look. This assembly ensures each bite has a harmonious mix of crumb, filling, and frosting — blueberry heaven at every forkful.

Make Ahead and Storage

Storing Leftovers

Wrap leftover cake tightly in plastic wrap or store in an airtight container in the fridge. It will keep fresh and moist for up to 3 days, allowing the flavors to meld even more.

Freezing

You can freeze this cake by wrapping cake layers separately in plastic wrap and foil to prevent freezer burn. Thaw overnight in the fridge before assembling or frosting. Buttercream also freezes well when sealed properly.

Reheating

Blueberry layer cake is best enjoyed chilled or at room temperature. If desired, allow the cake to warm slightly out of the fridge for about 20 minutes before serving to soften the buttercream and enhance the flavors.

FAQs

Can I substitute fresh blueberries with frozen ones in this recipe?

While fresh blueberries provide the best texture and flavor, frozen blueberries can be used if fresh aren’t available. Just be sure to thaw and drain them well to avoid adding too much moisture to the batter or filling.

What is the reverse creaming method mentioned in the recipe?

The reverse creaming method involves mixing the butter and dry ingredients before adding liquids and eggs. This technique creates a tender crumb and helps cakes stay moist and soft for longer.

Can I make the blueberry powder from scratch?

Absolutely! Simply dry freeze-dried blueberries in a food processor until you get a fine powder, then sift to remove seeds. This adds concentrated blueberry flavor without extra moisture.

Is it necessary to use kefir or buttermilk?

Kefir or buttermilk adds acidity which reacts with the leavening agents to help the cake rise and develop a tender crumb. If you don’t have these on hand, you can substitute with milk plus a little lemon juice or vinegar to mimic the acidity.

How long does the blueberry buttercream last?

Stored in an airtight container at cool room temperature, the blueberry buttercream will last 2 to 3 days. For longer storage, keep it refrigerated and allow it to come to room temperature before using.
