Rinse and dry the blueberries. Set them aside.
In a large bowl mix together 1 and 1/2 cups of buttermilk, 3/4 cups of sugar, 2 tsps of vanilla extract. Mix everything together well. Add in 2 cups of whipping cream.Mix it well again.
Pour the buttermilk, sugar, and vanilla into an ice cream machine.
Process the ice cream for about 25 minutes or so, then add in the blueberries. Add them slowly and push them down into the mixture as so that they're evenly distributed through the ice cream mixture.
Process the ice cream for an additional 10 minutes or so until it starts to firm up. Put the ice cream into a container and stick it in the freezer for an hour or two to harden further. Enjoy!
