Step‑by‑Step Instructions for Lemon Blackberry Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven is heating, prepare a 9-inch round cake pan by greasing it lightly with baking spray that contains flour. This step ensures that your Lemon Blackberry Cake will come out effortlessly later, allowing you to focus on the delightful flavors you’ll create.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine granulated sugar and lemon zest. Use your fingers to rub them together until fragrant. Next, add the all-purpose flour, baking soda, baking powder, and sea salt to the bowl, whisking them thoroughly. This mixture will serve as the base of the cake, providing structure and flavor, so make sure it’s well combined for the best results.
Step 3: Combine Wet Ingredients
Add the softened unsalted butter, Greek yogurt, eggs, and vanilla extract to the dry mixture. Using an electric mixer, beat on medium speed until everything is combined, which should take about 2 minutes. Then, increase to high speed and mix for an additional 30 seconds to achieve a smooth and fluffy cake batter, perfect for your refreshing Lemon Blackberry Cake.
Step 4: Fold in Blackberries
Gently toss fresh or frozen blackberries in a bit of flour before folding them into the batter. This will help distribute the berries evenly and prevent them from sinking. After you’ve incorporated the blackberries, pour the batter into the prepared cake pan and smooth the top with a spatula, ready for baking.
Step 5: Bake the Cake
Place the cake pan in the preheated oven and bake for approximately 50-55 minutes. To ensure an even bake, rotate the pan halfway through. The cake is ready when a toothpick inserted in the center comes out clean or with a few moist crumbs. Enjoy the intoxicating aroma of lemon and berries filling your kitchen!
Step 6: Cool and Remove from Pan
Once baked, remove the cake from the oven and allow it to cool in the pan for about 10 minutes. After cooling, gently run a knife around the edges and carefully remove the cake from the springform pan. Transfer it to a wire rack to cool completely, which might take another 30 minutes, allowing the cake to set perfectly for layering.
Step 7: Macerate the Blackberries
While the cake cools, prepare the filling by macerating blackberries in a bowl with sugar and lemon juice. Leave them to sit for about 10-15 minutes. This step draws out the berry juices, creating a flavorful mixture that will add a delicious burst of flavor between layers in your Lemon Blackberry Cake.
Step 8: Prepare Lemon Curd
For the lemon curd, combine egg yolks, sugar, salt, lemon zest, and lemon juice in a heatproof bowl. Place it over simmering water and whisk constantly until thickened, about 10 minutes. This creamy curd will add a rich texture to your cake, enhancing the lemony flavor that everyone will love.
Step 9: Mix in Mascarpone
After your lemon curd has thickened, remove it from heat and whisk in the mascarpone cheese until smooth and creamy. Allow this mixture to cool slightly before chilling it in the refrigerator until set, making it the perfect filling for your Lemon Blackberry Cake.
Step 10: Whip the Cream
In a separate bowl, whip heavy cream until stiff peaks form. Once your lemon curd has chilled, gently fold this whipped cream into the curd mixture, creating a light and airy filling. This whipped lemon mascarpone will be delightful and provide a refreshing contrast to the moist cake layers.
Step 11: Assemble the Cake
Now, it’s time to layer! Slice your cooled cake in half horizontally. Spread a layer of the lemon mascarpone filling onto the bottom layer, followed by a generous layer of macerated blackberries. Place the top layer back on and frost the top with the remaining filling.
Step 12: Chill and Serve
Finish by decorating the top of your Lemon Blackberry Cake with any remaining macerated blackberries. Chill the assembled cake in the refrigerator for at least 1 to 2 hours before slicing. This chilling time helps the flavors meld beautifully while allowing for cleaner cuts when serving.

Expert Tips for Lemon Blackberry Cake
-
Proper Measurement: Use a kitchen scale for precise measurements, especially for flour and sugar. This avoids dry or dense cake, ensuring your Lemon Blackberry Cake turns out light and fluffy.
-
Room Temperature Ingredients: Make sure your eggs and butter are at room temperature before mixing. This helps create a smoother batter and maintains the cake’s texture.
-
Don’t Overmix: After adding the dry ingredients to the wet, mix just until combined. Overmixing can develop gluten, resulting in a tough cake instead of a tender Lemon Blackberry Cake.
-
Cool Properly: Allow your baked cake to cool completely before frosting. This prevents melting your mascarpone frosting and ensures clean layers.
-
Chill Before Serving: Let the assembled cake chill in the fridge for a couple of hours. This allows flavors to meld and makes for neater slices when serving refreshing cake!

Fridge: Store your Lemon Blackberry Cake in an airtight container in the refrigerator for up to 3 days to maintain its freshness and flavor.

Thawing Tips: When ready to enjoy, place the frozen cake in the fridge overnight to thaw gently. This helps preserve texture and flavor.
Reheating: If you prefer a warm slice, microwave for 10-15 seconds or enjoy it at room temperature, letting the bright flavors shine!
