Preheat Your Oven: Start by preheating your oven to 350°F (175°C). This ensures that your cobbler bakes perfectly all the way through.
Prepare the Blackberries: In a medium bowl, mix the washed blackberries with half a cup of sugar. Set them aside to let the flavors meld while you prepare the batter.
Mix the Dry Ingredients: In another bowl, whisk together the flour, baking powder, salt, and remaining half cup of sugar until combined.
Combine Wet Ingredients: Add the melted butter and milk to the dry ingredients, stirring until you have a smooth batter. No lumps allowed!
Assemble the Cobbler: Pour the batter into a greased baking dish. Carefully spoon the blackberry mixture on top of the batter. Don't worry if it looks a little messy; that’s part of the charm!
Bake: Place the baking dish in the oven and let it bake for 40-45 minutes, or until the top is golden brown and bubbly.
Cool and Serve: Once it's done, allow the cobbler to cool slightly before serving. Scoop it into bowls and top with a scoop of vanilla ice cream if desired!
