Peel the peaches and slice each into 8 wedges.

In a mixing bowl, whisk together the flour, baking powder and salt. In the bowl of beat together the butter and granulated sugar, until smooth. Beat in the eggs, one at a time. Add the flour mixture and mix until smooth, I used a hand mixer.

Spray nonstick spray in an oven safe skillet 8-9 inch one. Heat the pan till it's warm through. Add the batter to the skillet.

Push the peach wedges into the batter. Cover the whole bottom. This way the peaches are in every bite.

Sprinkle the cinnamon and brown sugar on top of the buckle.

Bake for an hour check towards the end in case it's browning too soon. If it is cover and finish baking.
