Ingredients
- 7 cups sliced ripe peaches
- 1/2 cup granulated sugar
- 2 tbsp cornstarch
- 1 tbsp lemon juice
- 1 tsp vanilla extract
- 1/2 tsp cinnamon
- 1 1/2 cups all-purpose flour
- 1/3 cup granulated sugar
- 2 tsp baking powder
- 1/2 tsp kosher salt
- 6 tbsp cold unsalted butter, cubed
- 3/4 cup cold buttermilk
- 1 tbsp coarse sugar, optional
Instructions
Follow each step in order. The directions below are written so a beginner can understand what to do, what to look for, and when to move on to the next step.
- Step 1.Heat the oven to 375°F, butter a 9-inch square baking dish, and place it on a rimmed sheet pan in case the peach filling bubbles over.
- Step 2.Toss the peaches with sugar, cornstarch, lemon juice, vanilla, and cinnamon until the starch disappears and every slice looks glossy.
- Step 3.Transfer the peaches and their juices to the dish, spread them evenly, and bake for 10 minutes while preparing the biscuit topping.
- Step 4.Whisk flour, sugar, baking powder, and salt thoroughly, then cut in the cold butter until the mixture contains coarse pea-sized crumbs.
- Step 5.Pour in the cold buttermilk and fold gently just until no dry flour remains; a slightly shaggy dough produces a more tender biscuit.
- Step 6.Drop spoonfuls of dough over the hot peaches with small gaps for steam, then sprinkle coarse sugar over the tops if desired.
- Step 7.Bake for 30 to 35 minutes more, until the biscuits are deeply golden and a center biscuit is fully baked rather than wet underneath.
- Step 8.Rest the cobbler for 20 minutes so the peach juices set to a spoonable consistency, then serve warm without covering the crisp topping.
