Preheat Oven: Heat your oven to 350°F (175°C).
Prepare Peaches: Slice 5–6 large fresh yellow peaches into 1/4 inch slices.
Butter the Pan: Spread a small amount of melted butter on the bottom of a 9×13 inch baking pan.
Add Peaches: Place the peach slices evenly in the buttered pan.
Make the Batter: In a bowl, mix together 1/2 cup of melted butter, 1 cup of sugar, and 1 teaspoon of vanilla. Add 1 cup of flour, 1 teaspoon of baking powder, and a pinch of salt to the mixture. Stir until the mixture forms a cookie-dough-like batter.
Top the Peaches: Drop spoonfuls of the batter over the peaches. Spread the batter lightly with a spoon or your fingers. It doesn’t need to be perfect.
Bake the Cobbler: Place the pan in the oven and bake for 30 minutes, until the edges are bubbly and the top is golden.
Let it Stand: Allow the cobbler to sit for 20-30 minutes after baking for a thicker, saucy peach base.
Serve: Scoop the cobbler into bowls and serve warm with whipped cream or vanilla ice cream
