Ingredients

For the Lemon Blackberry Cake Layers:

• 3/4 cup unsalted butter, softened
• 1 cup granulated sugar
• 1 tsp vanilla extract
• 4 large eggs, separated
• Zest of 1 lemon
• 1 cup lukewarm milk
• 1 1/2 cups all-purpose flour
• 3/4 cup almond flour
• 4 tsp baking powder
• 1/4 tsp salt
• 1 cup fresh blackberries
• 1 tbsp cornstarch

For the French Buttercream:

• 1/3 cup water
• 1 cup granulated sugar
• 5 egg yolks
• 2 cups unsalted butter, softened
• 1/4 tsp lavender oil
• Purple food coloring (optional)

Instructions

Making the Cake Layers:

1. Preheat oven to 350°F (177°C). Line three 8-inch (20 cm) cake pans with parchment paper and lightly grease the sides.
2. In a large mixing bowl, use a hand mixer to cream together the butter and sugar for 2 to 3 minutes until light and fluffy.
3. Add the egg yolks, vanilla extract, and lemon zest, mixing until smooth. Pour in the milk but do not mix yet.
4. In a separate bowl, whisk together the all-purpose flour, almond flour, baking powder, and salt.
5. Sift the dry ingredients into the wet mixture and gently mix until just combined.
6. In another bowl, whisk the egg whites on high speed for 2 to 3 minutes until medium peaks form.
7. Gently fold the whipped egg whites into the cake batter using a spatula until fully incorporated.
8. Divide the batter evenly among the three cake pans.
9. Toss the fresh blackberries in cornstarch to coat them evenly. Distribute 6 to 8 blackberries per pan, spacing them evenly.
10. Bake for 25 minutes, or until a toothpick inserted in the center comes out clean.
11. Let the cakes cool in the pans for a few minutes before transferring to a wire rack to cool completely.

Making the French Buttercream Frosting:

1. In a stand mixer bowl, whisk the egg yolks on high speed for 2 to 3 minutes until thick and pale.
2. In a small saucepan, combine the water and sugar. Stir once to combine, then attach a candy thermometer to the side.
3. Heat the syrup over medium heat until it reaches 238°F (114°C), about 7 to 8 minutes.
4. With the mixer on medium speed, carefully pour the hot syrup into the egg yolks in a slow, steady stream, avoiding the whisk attachment.
5. Once all the syrup is added, increase the speed to high and beat until the mixture doubles in size and cools to lukewarm.
6. Gradually add the butter, one tablespoon at a time, mixing well after each addition. This process will take about 8 to 10 minutes.
7. When the buttercream thickens and holds its shape, mix in the lavender oil and purple food coloring if using.

Assembling the Cake:

1. Once the cake layers have completely cooled, spread a generous layer of buttercream between each layer.
2. Smooth the frosting over the top and sides of the cake for an even finish.
3. Garnish with fresh blackberries, lavender sprigs, and greenery for a beautiful presentation.

Tips

• Room Temperature Ingredients: Ensure all ingredients, especially butter and eggs, are at room temperature for the best texture.
• Gentle Mixing: Overmixing can make the cake dense. Stir just until ingredients are combined.
• Cornstarch Coating: Tossing the blackberries in cornstarch prevents them from sinking to the bottom of the cake layers.
• Slow Butter Addition: Adding the butter slowly to the French buttercream ensures a smooth, creamy texture.

Variations and Substitutions

• Gluten-Free Option: Substitute all-purpose flour with a 1:1 gluten-free baking flour.
• Dairy-Free Option: Use plant-based butter and almond milk instead of dairy ingredients.
• Berry Swap: Replace blackberries with raspberries or blueberries for a different fruit twist.
• Lemon Forward Flavor: Add 1 to 2 teaspoons of lemon juice to the batter for a stronger citrus taste.
