Instructions:

1. Preheat the Oven:
Preheat your oven to 350°F (175°C).

2. Prepare the Baking Pan:
Line the bottom of a 9-inch round baking pan with parchment paper. Lightly grease the sides of the pan with butter or a non-stick spray.

3. Separate the Eggs:
Separate the egg whites from the yolks. Place the egg whites in a large mixing bowl and the yolks in another.

4. Whip the Egg Whites:
Using an electric mixer or a whisk, beat the egg whites with a dash of salt until stiff peaks form. Set aside.

5. Combine Yolks and Sugar:
In the bowl with the egg yolks, add 1/2 cup of sugar and whisk or beat until the mixture is pale and creamy.

6. Add Wet and Dry Ingredients:
Slowly add the buttermilk to the yolk mixture, stirring until well combined. Fold in the ground almonds and baking powder until thoroughly mixed.

7. Incorporate the Egg Whites:
Gradually fold the stiff egg whites into the batter one third at a time, taking care to maintain the aeration. Gently fold until the mixture is homogeneous without deflating the egg whites.

8. Pour and Bake:
Pour the batter into the prepared baking pan. Smooth the top with a spatula if needed. Bake in the preheated oven for 30-35 minutes or until a skewer inserted into the center of the cake comes out clean.

9. Prepare the Lemon Glaze:
While the cake is baking, prepare the lemon glaze. In a small bowl, mix 1 cup of powdered sugar with 2 tablespoons of lemon juice until smooth and well combined.

10. Cool and Glaze:
Once the cake is done, remove it from the oven and allow it to cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely. Drizzle the lemon glaze over the cake once it has cooled.

11. Serve:
Slice and enjoy your delicious, flourless lemon buttermilk cake!
