Ingredients You’ll Need

To create this delightful Lemon Blueberry Layer Cake, you’ll want to gather ingredients that bring brightness, moisture, and a touch of natural sweetness. Each ingredient plays a pivotal role, from the fresh lemon zest that imbues the sponge with its signature citrus zing to the blueberries that provide juicy, tangy contrast.

• All-purpose flour: The sturdy base for a tender but structured cake that holds layers beautifully.
• Baking powder: Ensures your lemon sponge rises to light, airy perfection.
• Granulated sugar: Sweetens the cake while giving a subtle caramelized crust.
• Unsalted butter: Adds rich flavor and helps create a moist crumb in the sponge.
• Eggs: Important for binding ingredients and providing structure and richness.
• Fresh lemon zest and juice: The star of the show, delivering vibrant citrus flavor and a fresh aroma.
• Blueberries: Fresh or frozen, these bring natural sweetness and that signature color to the compote.
• Sugar (for blueberry compote): Helps amplify the natural sweetness of the berries without overpowering their tartness.
• Swiss meringue buttercream ingredients (egg whites, sugar, unsalted butter, vanilla extract): This silky frosting brings a creamy, smooth texture that balances the tart and sweet layers beautifully.

How to Make Lemon Blueberry Layer Cake

Step 1: Prepare the Lemon Sponge

Start by preheating your oven to ensure it’s just right for baking. Cream the unsalted butter with granulated sugar until fluffy and pale. Gradually add eggs one at a time, beating well. Carefully fold in the dry ingredients combined with the bright lemon zest and fresh lemon juice. This mixture creates that soft, airy lemon sponge with citrus notes bursting through. Pour the batter evenly into your cake pans and bake until golden and springy to the touch, then let the layers cool completely before assembling.

Step 2: Make the Blueberry Compote

While the sponge cools, it’s time to simmer fresh or frozen blueberries with a bit of sugar over medium heat. Stir gently until the berries begin to release their juices and the mixture thickens to a glossy, spoonable compote. This compote is what gives the cake its tart-sweet contrast and moist fruit layer, so don’t rush this step. Let it cool, so it doesn’t melt the buttercream later on.

Step 3: Whip Up the Swiss Meringue Buttercream

This luscious frosting is a game-changer! Warm egg whites and sugar over a simmering pot of water until sugar dissolves, then whip into a glossy meringue. Once cool, gradually beat in softened butter until you achieve a silky, spreadable buttercream. The result is a smooth canvas that wonderfully complements the zesty sponge and fruity compote layers without overpowering their flavors.

Step 4: Assemble Your Lemon Blueberry Layer Cake

Now for the fun part! Place the first lemon sponge layer on your serving plate and spread a generous layer of blueberry compote evenly. Next, pipe or spread a thick blanket of Swiss meringue buttercream on top. Repeat the process with the second layer and finish by frosting the entire cake with the remaining buttercream. Smooth it out or get creative with swirls—the aesthetics are all yours to play with!

How to Serve Lemon Blueberry Layer Cake

Garnishes

Decoration elevates this cake’s charm. Top your Lemon Blueberry Layer Cake with fresh blueberries strategically placed for pops of color. Edible flowers like violets or pansies add a delicate, elegant touch that’s sure to impress at any gathering. A light dusting of lemon zest can also brighten up the cake’s appearance, hinting at the flavors within.

Side Dishes

This cake is a stand-out star, but if you want to complement it, consider light accompaniments. A simple bowl of fresh berries, whipped cream, or a scoop of vanilla bean ice cream balances each bite perfectly. Pairing it with a fresh herbal tea or a crisp white wine enhances the overall experience without competing with the cake’s complexity.

Creative Ways to Present

Presenting this Lemon Blueberry Layer Cake on a beautiful cake stand instantly turns it into a centerpiece. For a fun twist, slice into smaller portions and serve as cake slices on delicate dessert plates with a drizzle of leftover blueberry compote. If you’re feeling adventurous, try incorporating lemon curls or tiny piped buttercream rosettes around the edges to give it a boutique bakery flair right at home.

Make Ahead and Storage

Storing Leftovers

Once assembled, store your Lemon Blueberry Layer Cake in an airtight container in the refrigerator. It will keep fresh for 3 to 4 days, allowing the flavors to meld beautifully. Just be sure to let it sit at room temperature for about 30 minutes before serving again to restore that soft, tender texture.

Freezing

If you want to prepare this cake ahead of time or save some for later, wrap it tightly in plastic wrap and then aluminum foil before placing it in the freezer. It freezes well for up to one month. When ready to enjoy, thaw it overnight in the fridge, then bring to room temperature before serving for the best texture and full flavor.

Reheating

Since this is a delicate cake with buttercream and fruit compote, avoid microwaving. Instead, letting it warm naturally at room temperature is the best way to enjoy every layer’s full taste and texture. If refrigerated, aim for about 20 to 30 minutes out of the fridge before slicing.

FAQs

Can I use frozen blueberries for the compote?

Absolutely! Frozen blueberries work wonderfully and are often more readily available year-round. Just thaw them slightly before cooking and drain any excess liquid if needed to avoid a runny compote.

Do I need a special mixer to make the Swiss meringue buttercream?

A stand mixer with a whisk attachment is ideal for whipping up Swiss meringue buttercream because it handles the volume and speed needed. However, a hand mixer can work if you have patience and a deep bowl.

Can I make this cake gluten-free?

Yes, you can substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Just make sure it includes xanthan gum or another binder to help maintain structure.

What if I don’t have fresh lemons?

Fresh lemon juice and zest provide vibrant, fresh flavor that’s essential for this cake’s character. If fresh lemons aren’t available, bottled lemon juice can be used, but zest should always come from fresh lemon for the best aroma.

How do I prevent the blueberry compote from bleeding into the buttercream?

Cool the compote completely before layering and consider chilling it in the fridge to thicken. You can also lightly spread a thin layer of buttercream before adding the compote to create a barrier and keep colors from bleeding.
