Combine 1/4 cup water with 1/2 cup sugar in a medium saucepan. Stir gently to mix, then heat over medium-high heat without stirring until it turns light brown, about 10-15 minutes. Remove from heat, quickly add 1 tablespoon bourbon, and pour evenly over the peaches.

In a separate bowl, whisk together the all-purpose flour, almond flour, baking powder, and remaining 1/4 teaspoon cinnamon. Slowly mix the dry ingredients into the wet batter until fully combined.
