Preheat the oven to 400 degrees F.
Place blueberries in a bowl, sprinkle on sugar, and toss to coat really well.
Spread the blueberries on a cookie sheet evenly. Place in oven and roast the berries for about 7 to 9 minutes.
Remove from oven and allow to cool completely.
Once the blueberries are cool, toss them in a blender with the ice cream, milk and vanilla extract. Pulse until it's combined but thick.
Remove and pour into serving glasses.
Serve with a big old blueberry loving smile!
