Sweet and Easy Peach Dessert

1 ½ teaspoons butter

4 fresh peaches - peeled, pitted, and diced

¼ cup maple syrup

1 cup all-purpose flour

2 tablespoons all-purpose flour

½ teaspoon salt

½ cup unsalted butter

2 tablespoons sour cream

3 egg yolks, beaten

1 cup white sugar

3 ⅓ tablespoons sour cream

2 tablespoons all-purpose flour

1 pinch salt

Melt 1/2 tablespoon butter in a saucepan over medium heat. Stir peaches, maple syrup, and a pinch of salt together in the melted butter; cook, stirring occasionally, until the mixture is syrupy, about 10 minutes. Remove from heat and set aside to cool.

Preheat oven to 425 degrees F (220 degrees C). Grease a 10x6-inch baking dish.

Mix 1 cup plus 2 tablespoons flour and 1/2 teaspoon salt together in a bowl. Mash unsalted butter into the flour mixture until lumps are the size of small peas. Blend 2 tablespoons sour cream into the mixture; mix until you have a dough-like mixture. Pat the dough into the bottom and up the sides of the prepared baking dish.

Bake in preheated oven until browned and crust-like, about 10 minutes.

Spread peach mixture over the crust into an even layer.

Beat egg yolks, sugar, 3 1/3 tablespoons sour cream, and 2 tablespoons flour together in a small bowl; pour evenly over the layer of peaches. Cover the dish with aluminum foil.

Bake in the preheated oven for about 35 minutes. Remove aluminum foil and continue baking until a toothpick inserted into the center comes out clean, about 10 minutes. Let cool slightly before serving warm.
