Preheat oven to 375°F.
In a bowl, whisk together flour, ⅓ cup sugar, baking powder, salt, and ginger.
Next, cut in the butter, using your fingers, until it gets a bit crumbly.
Now, with a spoon, stir in the milk and vanilla extract until smooth.
In a separate bowl, stir together the blueberries, sugar, lemon juice, and lemon zest until all the blueberries are coated, then place the berries in the bottom of a Dutch oven.
Finally, spoon drops of cobbler batter here and there, on top of the blueberries.
Bake, uncovered, for 45 to 50 minutes or until the cobbler topping turns a light golden brown.
Let cool just slightly and serve warm, with a scoop of vanilla ice cream or homemade whipped cream.
