How to Make Lemon Blueberry Layer Cake
-
Preheat the Oven: Begin by preheating your oven to 175°C. Lightly grease three 20-cm round cake pans, then line them with parchment paper. Don’t forget to butter or spray the paper lightly for easy removal!
-
Mix Wet Ingredients: In a mixer bowl, combine the melted coconut oil, Greek yogurt, eggs, granulated sugar, brown sugar, vanilla extract, buttermilk, lemon juice, and zest. Beat everything together until the mixture is smooth and well-blended.
-
Add Dry Ingredients: Gradually incorporate the all-purpose flour, baking powder, baking soda, and kosher salt into the wet mixture. Mix until just combined—no need to overdo it!
-
Fold in Blueberries: Toss the blueberries in 8 g of flour to prevent them from sinking. Gently fold these floured blueberries into the batter, along with the blueberry jam, ensuring some swirls remain visible for a beautiful effect.
-
Bake the Cakes: Divide the batter evenly among the prepared pans. Bake in the preheated oven for 30–35 minutes, or until the tops are firm and spring back when touched. Allow them to cool for 5 minutes before loosening the edges with a knife and flipping onto wire racks to cool completely.
-
Prepare the Frosting: In a clean mixer bowl, beat together the salted butter, mascarpone, and powdered sugar until fluffy. Divide the frosting into three bowls; mix blueberry jam into two bowls for a lovely gradient effect, while leaving one bowl plain.
-
Assemble the Cake: Place the first cake layer on a serving plate and spread the darkest buttercream evenly on top. Add the second layer, this time using the lighter buttercream, followed by the final layer topped with the plain buttercream.
-
Frost the Sides: Lightly frost the sides of the cake with the different shades of buttercream to create a lovely marbled effect. Chill in the fridge for about 30 minutes before serving to set beautifully.
Optional: Garnish with additional blueberries on top for a stunning presentation!

Make Ahead Options
These Lemon Blueberry Layer Cakes are perfect for busy home cooks looking to save time! You can bake the cake layers up to 3 days in advance; simply cool them completely, wrap them tightly in plastic wrap, and refrigerate. The blueberry jam can also be prepared a week ahead and stored in an airtight container. On the day of serving, whip up the frosting, layer the cakes with it, and give the sides a light coat. For a gorgeous marbled effect, assemble and frost the cake shortly before serving to ensure it looks just as stunning and delicious. This way, you can enjoy your time at the gathering rather than being stuck in the kitchen!

Reheating: When ready to enjoy your frozen cake, let it thaw overnight in the fridge. For a freshly baked taste, you can warm individual slices in the microwave for about 10-15 seconds.

Chef's Helpful Tips
- When making the Lemon Blueberry Layer Cake, ensure your ingredients are at room temperature to achieve a smoother batter and a more evenly baked cake.
- A common mistake is overmixing the batter once the flour is added; mix just until combined for a lighter texture.
- Coating the blueberries in flour not only helps them stay suspended in the batter but also prevents them from bleeding too much color into the cake.
- Bake the cakes until a toothpick comes out clean, checking around the 30-minute mark to avoid overbaking, which can lead to a dry cake.
Lemon Blueberry Layer Cake Recipe FAQs
How do I choose the best blueberries?
Absolutely! When selecting blueberries, look for plump, firm berries that are deep blue in color. Avoid any that have green or red spots, as these are under ripe. Fresh blueberries should be dry and clean, with no mold or dark spots all over the surface. If using frozen blueberries, choose those without added sugars for the best result.
How should I store my Lemon Blueberry Layer Cake?
Very! To keep your Lemon Blueberry Layer Cake fresh, store it covered with plastic wrap or in an airtight container in the fridge for up to 3 days. This helps maintain its moisture and prevents it from absorbing any odors from the refrigerator. Just make sure it’s cooled completely before wrapping!
Can I freeze slices of my Lemon Blueberry Layer Cake?
Absolutely! To freeze your cake, wrap each slice tightly in plastic wrap and then in aluminum foil. This will keep it well-protected and preserve its flavor. You can freeze the cake for up to 3 months. When you’re ready to enjoy it, simply thaw it overnight in the fridge, or warm individual slices in the microwave for about 10-15 seconds for a freshly baked taste.
What should I do if the cake is too dry?
If you find that your Lemon Blueberry Layer Cake is a bit too dry, don’t fret! This can happen if it’s overbaked. Be sure to check for doneness around the 30-minute mark. To remedy a dry cake, you can make a simple syrup by combining equal parts water and sugar, heating until the sugar dissolves, and then brushing it onto the layers before frosting. This adds moisture and enhances the flavor beautifully.
Does the cake contain any common allergens?
Great question! This Lemon Blueberry Layer Cake contains common allergens such as eggs, dairy (Greek yogurt, buttermilk, butter), and gluten (all-purpose flour). If you’re baking for someone with a food allergy, consider using substitutions like almond or coconut milk instead of buttermilk, and a gluten-free flour blend can replace all-purpose flour. Gluten-free baking can be a little tricky, so make sure to follow specific recipe guidance for the best results.
