Start by preheating your oven to 350* fahrenheit.
Measure your fruit and drizzle with 2 tbsp. maple syrup and ½ tbsp. lemon juice, stir and set aside.
Melt butter in cast iron skillet over low heat. If using a baking dish, melt the butter in the dish by putting it in the preheating oven for a few minutes.
Combine flour, baking powder, milk, maple syrup, vanilla extract and salt in a medium mixing bowl.
Pour the flour mixture over top of the melted butter and stir gently, this will make our "pie crust" for the cobbler.
Next, layer the fruit mixture on top of the flour mixture in the baking dish or cast iron skillet.
Sprinkle with cinnamon and/or nutmeg if desired.
Bake in the oven for 25-30 minutes, or until the topping is browned. The berries will fall to the bottom of the dish and the flour mixture will rise in some parts, this is what you want.
Allow to cool for 5-10 minutes and serve.
Store leftovers in the refrigerator.
