This Sourdough Peach Cobbler bursts with ripe, juicy peaches and is topped with buttery, fluffy sourdough biscuits made from discard. It’s an easy summer dessert you'll want all season long.
Preheat your oven to 350°F. Lightly butter an 8-inch square aluminum baking dish and set it aside.
In a large bowl, whisk together the sugar, lemon juice, sourdough discard, flour, vanilla, and salt. Add the sliced peaches and stir until they’re evenly coated in the mixture.
Pour the peach filling into your prepared baking dish and spread it out evenly. Bake for 20 minutes to give the peaches a head start and help them soften.
While the peaches are roasting, prepare the biscuit topping. Start by combining the flour, sugar, baking powder, and salt in a large bowl. Add the butter and cut in using your fingers, a fork, or a pastry blender until it resembles coarse sand. Create a small well in the center of the mixture and pour in the cream, milk, and sourdough discard. Gently fold together just until no dry streaks remain.
2 cups (240 grams) all-purpose flour, 2 tablespoons (25 grams) granulated sugar, 1 tablespoon baking powder, 1 teaspoon Diamond Crystal Kosher Salt, ½ cup (113 grams, 1 stick) unsalted butter, ½ cup heavy cream, ½ cup whole milk, ½ cup (100 grams) sourdough starter discard
Once the peaches are out of the oven, spoon 9 dollops of biscuit dough evenly over the warm filling. Sprinkle the top with coarse sugar, if using.
Coarse sugar
Return the pan to the oven and bake for 45–50 minutes, or until the biscuits are golden and the peach filling is bubbling around the edges.
Let cool for at least 30 minutes before serving to allow the filling to set.
