Preheat the oven to 350°F, and grease a small oven-proof skillet or baking dish well.
In a bowl, stir together the blueberries, 1 tablespoon sugar and lemon juice until well combined.
Spread the berries in the bottom of the baking dish or skillet.
Blend together all of the topping ingredients until smooth.
Layer the topping over the berries.
Bake for 25-30 minutes until browned and cooked through.
Notes
Frozen blueberries can be used but will release some of their juices as they thaw during baking. You may want to reduce the amount of liquid in the recipe to account for the extra liquid from the frozen blueberries.Use fresh blueberries. The best blueberry cobbler is made with fresh and ripe blueberries. Frozen berries can also be used but they can release more juice as they thaw during baking so you may need to adjust the liquid or add a little cornstarch.Adjust the sugar to taste. The filling of the cobbler should have a good balance of sweetness and tartness. Lemon juice adds tartness while sugar sweetens it up.Use the right size baking dish. To ensure the cobbler cooks properly, place it in an appropriately sized baking dish or ramekin. A small cast iron skillet works well for two servings. Or, divide it between two smaller ramekins.Serve warm. Once out of the oven, let the cobbler cool slightly before serving with a scoop of vanilla ice cream on top for extra deliciousness.
