- 3 cup blackberries, rinsed
- 1/4 cup sugar
- 1 teaspoon lemon zest
- 1 tablespoon lemon juice
- 1/2 teaspoon cinnamon
- 1 teaspoon cornstarch
- 1 cup flour
- 1/4 cup sugar
- 1/2 teaspoon baking powder
- dash of salt
- 4 tablespoon butter, chilled and cut into chunks
- 1 egg
- 1/4 cup milk
- Mix together the blackberries, sugar, lemon zest, lemon juice, cinnamon, and cornstarch in a bowl and let it sit for half an hour.
- Preheat the oven the 350 degrees. In another bowl, mix together the flour, sugar, baking powder, and salt. Cut the butter into the mixture, using 2 knives or a dough blender — the dough should begin to form into crumbs. Stir in the egg and milk until everything is combined and the dough is uniform throughout.
- Transfer the berries to an 8-inch round baking pan and spoon the dough on top. Bake the cobbler for 30 minutes, or until the fruit is bubbly and the dough starts to brown on top. Serve immediately.
