Quesadilla Salvadorena

Cream together the small stick of butter and 1 cup of sugar in a large mixing bowl until light and fluffy, approximately 2–3 minutes.

Beat the 3 eggs into the butter-sugar mixture one at a time, mixing well after each addition to create a smooth batter.

Stir in the 1 cup of sour cream until fully incorporated into the wet mixture.

In a separate bowl, whisk together the 1 cup of flour, 1 teaspoon of baking powder, and the 4 oz of grated Parmesan cheese.

Fold the dry ingredients into the wet mixture until just combined, being careful not to overmix.

Preheat the oven to 350°F (175°C) and lightly grease a baking dish or round cake pan.

Pour the batter into the prepared baking dish and smooth the top with a spatula.

Sprinkle the sesame seeds evenly over the top of the batter.

Bake in the preheated oven for 20–25 minutes until the top is golden brown and a toothpick inserted into the center comes out clean.

Remove from the oven and allow to cool in the pan for 5 minutes before slicing and serving.
