Prepare the Apple: Peel and grate the apple. Add a splash of lime or lemon juice to prevent browning.

Make the Batter: In a mixing bowl, break the egg and add the sugar and vanilla sugar. Mix well until combined.

Stir in the yogurt and milk until the mixture is smooth.

Add the baking powder, rum, and salt. Mix well.

Gradually add the flour, stirring until the batter is smooth and free of lumps.

Fold in the grated apple.

Let the batter rest for 10 minutes.

Cook the Pancakes: Heat a pan over medium heat and lightly oil it.

Spoon about 1 tablespoon of batter onto the pan for each pancake.

Cook until bubbles form on the surface and the edges are set, then flip and cook until golden brown on the other side.

Serve: Serve the pancakes warm, and enjoy the soft, delicious apple pancakes!
