What Ingredients You Will Need

This Lemon Blueberry Chantilly Cake uses simple, fresh ingredients that come together to create a masterpiece. Here’s what you’ll need:

• For the Cake:
• 2 1/2 cups (310g) all-purpose flour
• 1 tablespoon baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 1 cup (225g) unsalted butter, softened
• 2 cups (400g) granulated sugar
• 4 large eggs, room temperature
• 1/2 cup (120ml) fresh lemon juice
• 1 tablespoon lemon zest
• 1 cup (240ml) buttermilk, room temperature
• 1 1/2 cups (225g) fresh blueberries (tossed lightly in flour to prevent sinking)
• For the Chantilly Frosting:
• 2 cups (480ml) heavy whipping cream, chilled
• 8 ounces (225g) mascarpone cheese, softened
• 3/4 cup (90g) powdered sugar
• 1 teaspoon vanilla extract
• Optional Garnishes:
• Extra fresh blueberries
• Lemon slices or zest
• Fresh mint leaves

Pro Tip: Use fresh, ripe blueberries and organic lemons for the best flavor. If mascarpone isn’t available, cream cheese can be a substitute—it’s slightly tangier but works beautifully!

Equipment Needed

Here’s the gear you’ll need to whip up this stunning cake:

• Two 9-inch round cake pans
• Mixing bowls (at least two)
• Electric mixer or stand mixer
• Rubber spatula
• Cooling rack
• Offset spatula (for frosting)
• Microplane or grater (for lemon zest)
• Pastry bag (optional for decorative frosting)

If you don’t have cake pans, you can use a large oven-safe dish and adjust the baking time slightly. Just make sure to grease it well!

Preparation Method

1. Preheat Your Oven: Set the oven to 350°F (175°C). Grease and flour your cake pans or line them with parchment paper for easy removal.
2. Prepare the Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Cream the Butter and Sugar: Using an electric mixer, beat the softened butter and sugar until light and fluffy—this should take about 3-4 minutes.
4. Add the Eggs and Lemon: Beat in the eggs one at a time, followed by the lemon juice and zest. The mixture may look slightly curdled, but that’s okay.
5. Combine Wet and Dry Ingredients: Alternately add the dry ingredients and buttermilk to the butter mixture, beginning and ending with the dry ingredients. Mix until just combined—avoid overmixing.
6. Fold in the Blueberries: Toss the blueberries in a little flour (to prevent sinking) and gently fold them into the batter using a spatula.
7. Bake: Divide the batter evenly between the prepared pans and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let them cool completely on a wire rack.
8. Make the Chantilly Frosting: In a chilled bowl, whip the heavy cream until soft peaks form. In a separate bowl, beat the mascarpone, powdered sugar, and vanilla until smooth. Fold the whipped cream into the mascarpone mixture until fully combined.
9. Assemble the Cake: Place one cake layer on a serving plate and spread a generous layer of frosting on top. Add the second layer and frost the top and sides. Smooth with an offset spatula.
10. Decorate: Garnish with fresh blueberries, lemon slices, and mint leaves if desired.

Let the cake chill for at least 30 minutes before serving for cleaner slices. Trust me—you’ll want to snap a photo before digging in!

Cooking Tips & Techniques

• Room Temperature Ingredients: Make sure your butter, eggs, and buttermilk are at room temperature for a smoother batter.
• Prevent Blueberry Sinking: Tossing the blueberries in flour helps distribute them evenly throughout the cake.
• Don’t Overmix: Overmixing can lead to a dense cake—stop as soon as the ingredients are combined.
• Chilled Frosting: Keep all frosting ingredients cold for the best texture and flavor.
• Decorating Made Easy: Use a pastry bag with a star tip for decorative piping, or keep it rustic with a simple spatula spread.

If your cake layers dome while baking, level them with a serrated knife for a polished look. And don’t worry—those scraps are perfect for snacking!

Variations & Adaptations

• Gluten-Free Option: Swap the all-purpose flour with a 1:1 gluten-free baking flour blend.
• Dairy-Free Version: Use coconut milk instead of buttermilk and dairy-free cream cheese in the frosting.
• Berry Swap: Substitute blackberries, raspberries, or strawberries for the blueberries for a different flavor profile.
• Zesty Lime Twist: Add lime juice and zest instead of lemon for a tropical vibe.

I once tried this with raspberries and lime—it was a hit at a garden party! Feel free to experiment and make it your own.
