Preheat the Oven: Begin by preheating your oven to 450°F (230°C).
Melt the Butter: In a microwave-safe bowl, melt the butter. Once melted, pour it into a 9x13 inch baking dish, ensuring the bottom is fully coated.
Prepare Dry Ingredients: In a large mixing bowl, whisk together the flour, baking powder, sugar, and salt.
Add the Milk: Create a well in the center of your dry ingredients and gradually pour in the milk. Using a spoon or spatula, gently fold the milk into the dry ingredients until a soft dough forms. The dough will be sticky and somewhat wet.
Shape the Biscuits: Using a spoon or your hands (lightly floured, if needed), drop spoonfuls of the dough into the baking dish with the melted butter. It's okay if the biscuits touch each other.
Bake: Place the baking dish into the preheated oven and bake for 20-25 minutes, or until the biscuits are golden brown on top and have absorbed most of the butter.
Serve: Remove from the oven and allow the biscuits to cool slightly in the dish before serving. Make sure to spoon any leftover butter from the dish over the top of the biscuits for extra flavor.
