Preheat a medium nonstick frying pan over medium heat. Spray lightly with cooking spray and pour in a small amount of batter (1/6 cup was perfect for my size pan). While pouring in the batter, pick the pan up from the heat and tilt until the batter covers the bottom of the ban. Cook until just barely turning brown at the edges and gently flip, cooking again until lightly browned. Remove from the pan and set aside while cooking the peaches.
In a medium pan, add peaches, butter, maple syrup, and allspice. Cook over medium heat until the syrup has thickened and bubbles, about 5 minutes. Gently stir and add 1/4 teaspoon kosher salt.
To serve, fold crepes into quarters and top with peaches.
