Start by preheating the oven to 375°F. You’ll need a large casserole pan for the recipe.
Slice each peach in half, then into thin slices, about ¼-inch thick. Place the sliced peaches into the casserole pan.
Add the lemon juice and vanilla extract, followed by the sugar, cinnamon, flour, cornstarch, and salt. Use a spatula to toss the peaches until they’re well coated in the dry ingredients. You shouldn’t have patches of dry flour.
Cube the ¼-cup unsalted butter into small pieces, then drop them over the peaches.
Making the Buttermilk Biscuits:
For the biscuits: cube the butter into small pieces and place it into the freezer for a few minutes. It needs to be ice cold.
Place the flour, sugar, baking soda, baking powder, and salt into a food processor. Add the chilled butter and pulse until a crumbly mixture forms, about 30 seconds to a minute.
Don’t have a food processor? Cut the butter into the dry ingredients using a pastry cutter or two large forks.
Add in the buttermilk and vanilla extract last. Pulse for about 30 seconds to a minute, until a thick biscuit batter forms.
Drop large spoonfuls of the biscuit batter on top of the peaches, evenly spaced over the casserole.
Baking Instructions:
Bake the peach cobbler at 375°F for 40 to 45 minutes, until the biscuits are golden-brown, and the peach filling has cooked. After baking for 25 minutes, lay a sheet of foil over the cobbler to prevent the biscuits from getting too dark.
Remove the cobbler from the oven and put onto a wire rack to cool. Allow the cobbler to cool for 30 minutes prior to enjoying. This will allow the filling to thicken further.
Serving Suggestions:
Enjoy this incredible peach cobbler while it’s still warm, after about 30 minutes of cooling. Use a spoon to scoop out the peach cobbler into bowls.
Add a scoop of vanilla ice cream or peach ice cream to each serving and enjoy immediately. Warm up any leftovers before enjoying again.
