Ingredients

For the Blueberry Topping

• 1½ cups fresh blueberries
• ⅓ cup brown sugar
• ¼ cup unsalted butter

For the Cake Batter

• 2 large eggs, separated
• ¾ cup granulated sugar

• 1½ cups all-purpose flour
• 2 teaspoons baking powder
• ½ teaspoon salt
• ½ cup milk

Optional for Serving

Instructions

1. Prepare the Pan

Preheat the oven to 350°F (175°C).

Grease a 9-inch round cake pan or springform pan.

Spread the fresh blueberries evenly over the bottom of the pan.

2. Make the Caramel Topping

In a small saucepan, melt ¼ cup butter with the brown sugar over medium heat.

Stir until the sugar dissolves and the mixture becomes smooth.

Let it cool for about 2 minutes, then pour evenly over the blueberries.

3. Whip the Egg Whites

Separate the eggs.

Place the egg whites in a clean bowl and beat until stiff peaks form.

Set aside.

4. Make the Cake Batter

In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.

Beat in the egg yolks one at a time.

Mix in the vanilla extract.

5. Combine Dry Ingredients

In a separate bowl, whisk together:

• Flour
• Baking powder
• Salt

Gradually add the dry ingredients to the butter mixture, alternating with the milk.

Mix just until combined.

6. Fold in Egg Whites

Gently fold the whipped egg whites into the batter until no white streaks remain.

Do not overmix.

7. Assemble

Carefully spread the batter over the blueberry layer.

Smooth the top evenly with a spatula.

8. Bake

Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean.

9. Cool and Invert

Allow the cake to cool in the pan for 15 minutes.

Run a knife around the edges if needed.

Place a serving plate over the pan and carefully invert the cake.

Lift off the pan slowly to reveal the caramelized blueberry topping.
