In a mixing bowl, combine sliced peaches, brown sugar, cinnamon, and lemon juice. Toss to coat and set aside.

In a large mixing bowl, whisk together flour, sugar, baking powder, and salt.

In another bowl, mix milk, egg, and melted butter. Combine wet and dry ingredients until just mixed.

Preheat a griddle over medium heat and lightly grease it.

Pour 1/4 cup of batter onto the griddle for each pancake. Cook until bubbles form on the surface, then flip and cook until golden brown.

In a small bowl, mix flour, oats, cold butter, brown sugar, and cinnamon until crumbly.

Stack pancakes on a plate, top with peach mixture, and sprinkle cobbler crust on top. Serve warm.
