Instructions

1. Preheat oven to 350.
2. In a large mixing bowl, use a wooden spoon to gently combine the berries, cornstarch or arrowroot, sugar, and lemon juice. Transfer to an 8×8 baking dish.
3. In a small mixing bowl, whisk together the flour, baking powder, and salt.
4. In the bowl of a stand mixer with a paddle attachment, beat together butter and 1/2 cup sugar on medium high speed until creamy, about 1 minute. Beat in vanilla. Add flour mixture and mix on medium speed until evenly crumbly. With the mixer running on low, gradually pour in milk and beat for another minute, until batter is light and fluffy.
5. Dollop batter over berry filling and use a knife or offset spatula to gently spread batter evenly over the berries. Sprinkle remaining 3 tablespoons sugar over the batter. Drizzle hot water over the sugar, melting it right before it goes in the oven.
6. Bake for 70-80 minutes, until golden brown and crackly. Let the cobbler sit for at least 30 minutes to set before serving. Serve with ice cream or greek yogurt.
