Preheat the oven to 350°F (175°C).

In a mixing bowl, combine the drained peaches, brown sugar, cinnamon, and lemon juice. Stir until well mixed.

In another bowl, whisk together the flour, granulated sugar, baking powder, and salt.

Add the milk and melted butter to the dry ingredients and mix until just combined.

Pour the peach mixture into the bottom of a greased 9x9 inch baking dish.

Spoon the topping mixture evenly over the peaches.

Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown.

Let cool slightly before serving.
