Easy Homemade Blender Ice Cream

"Our air conditioner died this week, so we’re doing everything we can to keep cool, including eating a slew of blender ice creams. This DIY blizzard is made simply with milk, powdered sugar and vanilla, along with your favorite mix-ins, right in the @vitamix (I’ll take peanut butter and dark chocolate, please!)"
