Quesadilla Salvadoreña (Sweet Cheese Bread)

Mix Parmesan cheese with milk until combined. Set aside.

In a bowl, beat egg whites until you have soft peaks. One by one, add yolks, beating continuously. Set aside.

In another bowl, sift rice flour and baking powder. Stir in sugar. Add egg mixture and mix until incorporated. Add sour cream, butter, and the Parmesan cheese and milk mixture. Mix well.

Preheat oven to 375°F. Prepare a 9×13 inch dish by flouring and buttering it lightly. Pour the mixture inside and spread it evenly. Sprinkle some sesame seeds on top.

Bake for about 35–40 minutes or until a toothpick inserted comes out clean.
