Step 1

Preheat oven to 375°F. Spray a 9x13 baking dish with nonstick cooking spray.

Step 2

Add all of the “Peach” ingredients (peaches through salt) to the baking dish. Toss to combine then spread into an even layer. Bake for 15 minutes (it will be very watery after 15 minutes but will thicken later). Meanwhile, prepare the topping.

Step 3

Add the flour, sugar, baking powder, and salt to a large food processor (or large bowl). Pulse (or whisk) until combined. Add the cubed butter and pulse several times until the mixture resembles coarse crumbs (the largest piece of butter should be no larger than pea-size). If not using a food processor, cut the butter into the dry ingredients with a pastry cutter.

Step 4

Using a liquid measuring glass, whisk the vanilla into the buttermilk then pour into the feed tube. Pulse a few times to moisten (don’t overmix). If not using a food processor, make a well in the center of the mixture and add the buttermilk to the center. Fold together with a spatula until it begins to come together but don’t overwork the dough.

Step 5

Remove peaches from oven and immediately add the topping (the peaches need to be piping hot to cook the bottom of the topping). To add the topping, drop it by small spoonfuls all over the peaches, leaving a few gaps so the filling can steam. Sprinkle the topping with raw sugar and ground cinnamon.

Step 6

Bake in middle of oven at 375°F for 45-55 minutes, until the filling is thick and bubbling and the topping is golden.
