Gluten-Free Peach Cobbler

To prepare biscuits: Preheat oven to 425 degrees F. Lightly grease a 7-by-11-inch baking dish and line a rimmed baking sheet with foil. Whisk flour, 2 tablespoons sugar, baking powder, baking soda and 1/4 teaspoon salt in a medium bowl. Using a pastry blender or fork, cut butter into the flour mixture until the mixture resembles coarse meal. Whisk buttermilk, egg, oil and 2 teaspoons lemon juice in a small bowl; stir into the flour mixture until well incorporated. Cover the dough with plastic wrap and let stand for 30 minutes.

Meanwhile, prepare peach filling: Whisk sugar, cornstarch, cinnamon, ginger and salt in a small bowl. Toss peaches with lemon juice in a large bowl; add the sugar mixture to the peaches and stir well to combine. Spoon the mixture into the prepared baking dish; place the dish on the prepared baking sheet. Bake until bubbly throughout, about 15 minutes.

Remove the cobbler from oven and top the filling with 10 mounds of biscuit dough (about 1/4 cup per mound). Bake until the biscuits are golden brown, 20 to 25 minutes. Cool on a wire rack for 10 minutes; serve warm.
