How to Make Lemon Blueberry Layer Cake

Ready to dive into your baking adventure? Here, I’ll guide you through the steps to create a stunning Lemon Blueberry Layer Cake. It’s easier than you think, and trust me, the rewards are delicious!

Step 1: Prepare Your Baking Pans

Let’s get started by preheating your oven to 175°C (350°F). While that’s warming up, take three 20-cm round cake pans and lightly grease them. For added security, line them with parchment paper as well. A light butter or baking spray finish will prevent any sticky situations and help the cakes slide right out!

Step 2: Mix the Batter

In a mixer bowl, combine the melted coconut oil with Greek yogurt, eggs, both sugars, vanilla extract, buttermilk, fresh lemon juice, and grated lemon zest. Mix this all together until everything combines into a smooth batter. Now, slowly add in your all-purpose flour, baking powder, baking soda, and kosher salt. Remember, mix just until blended—overmixing can lead to a dense cake. We want light and fluffy!

Step 3: Add the Blueberries

To ensure those lovely blueberries stay suspended in the batter, coat them in 1 tablespoon of flour before adding them. Gently fold the blueberries into the batter using a spatula, ensuring they’re evenly distributed without breaking apart. Just before you’re done, swirl in some high-quality blueberry jam—this adds a beautiful burst of flavor!

Step 4: Bake the Cake Layers

Divide the batter evenly between the prepared pans. Now, pop them into the preheated oven and bake for 30–35 minutes. A good check for doneness is pressing gently on the cake’s center; it should spring back. If a toothpick inserted into the center comes out clean, then your cakes are ready to cool.

Step 5: Prepare the Buttercream

While your cake layers are cooling, it’s time to whip up the buttercream! In a clean mixer bowl, beat together the room temperature salted butter, mascarpone (or cream cheese), and powdered sugar until it’s light and fluffy. Separate the buttercream into three bowls. In one bowl, mix in 1–2 tablespoons of blueberry jam for a vibrant and sweet frosting. In the second bowl, add 2–3 tablespoons of jam, and leave the last bowl plain.

Step 6: Assemble the Cake

Once your cake layers are completely cool, it’s assembly time! Place the first layer on your serving plate and generously spread the darkest blueberry buttercream on top. Add the second layer, topping it with the lighter buttercream. Finally, place the last layer on top and spread the plain buttercream all over the cake. Don’t forget to frost the sides of the cake lightly, creating a marbled effect with the different shades of buttercream!

Step 7: Chill Before Serving

Your Lemon Blueberry Layer Cake deserves a little time to chill. Pop it in the fridge for 30 minutes. This helps the buttercream set well and makes cutting the cake easier. Plus, chilling enhances the flavors, bringing everything together beautifully. Serve it chilled, and prepare for the smiles to come!

Tips for Success

Use room temperature ingredients for better mixing and texture.
Don’t skip the parchment paper; it’s a lifesaver for easy removal.
To keep your layers even, weigh the batter in each pan.
Allow the cakes to cool completely before frosting to prevent melting.
For added flavor, zest extra lemon into your buttercream.
Use a cake leveler to trim any domed tops for a neat appearance.

Equipment Needed

20-cm round cake pans: You can use square pans if you prefer a different shape.
Mixing bowl: Any large bowl will do.
Electric mixer: A hand mixer works fine, or you can opt for whisking by hand.
Spatula: A silicone spatula is great for folding in ingredients.
Baking sheet: Use it for catching overflow if needed.

Variations of Lemon Blueberry Layer Cake

Gluten-Free: Substitute all-purpose flour with a high-quality gluten-free flour blend for a delicious gluten-free option.
Whole Wheat Version: Use whole wheat flour to add more fiber and a nutty flavor while keeping it wholesome.
Vegan Option: Replace eggs with flax eggs and use non-dairy milk and yogurt to create a vegan-friendly dessert.
Lemon Poppy Seed Cake: Add a tablespoon of poppy seeds to the batter for an added crunch and flavor contrast.
Mixed Berries: Blend blueberries with raspberries or strawberries for a delightful mixed berry layer cake.
Double Lemon: Enhance the lemon flavor by adding lemon extract in the batter and lemon zest in the frosting.
Cream Cheese Frosting: Swap mascarpone with cream cheese for a tangier frosting that pairs beautifully with the sweetness.

Serving Suggestions

Pair with a dollop of whipped cream for added creaminess and visual appeal.
Serve alongside a refreshing lemon sorbet to enhance the citrus flavors.
Accompany with a crisp, chilled glass of iced tea or lemonade for a lovely afternoon treat.
Garnish with fresh mint leaves for an extra pop of color and freshness.
Dust with powdered sugar before serving for an elegant touch.

To make a dairy-free Lemon Blueberry Layer Cake, substitute buttermilk with a plant-based milk mixed with a splash of vinegar and Greek yogurt with a dairy-free alternative. Use coconut oil instead of butter for the frosting to keep it creamy and delicious!
