1 cup all purpose flour
1/2 cup granulated sugar
1/2 cup packed light brown sugar
1/2 teaspoon cinnamon
dash of nutmeg
1/4 teaspoon salt
1 stick cold unsalted butter, cut into pieces
6 peaches peeled and sliced
grated zest and juice of 1/2 lemon
2 tablespoons pure maple syrup
Preheat oven to 350 degrees. Start with the crumb mixture: in a medium bowl, combine the flour, granulated sugar, brown sugar, cinnamon, nutmeg, and salt. Add the butter to the bowl and use a fork or pastry blender to cut it into the flour mixture.
Place the peaches in a bowl and add the lemon zest. Mix in the lemon juice and maple syrup and gently stir the peaches to combine. Pour the peaches into a 9-inch square or 8x12-inch baking dish. Top with the crumb mixture, evening out the surface with a fork. Cover tightly with foil and bake for 15 minutes. Remove the foil and bake for 30 minutes more.
