Be sure to follow these directions precisely, and allow ample preparation time.
Find two drinking glasses; I use 12 oz. size.
In one glass, drop in strawberries, blackberries, and raspberries until they are close to the top. If you don't have the raspberries or the blackberries, drop in a chunk of peach. Add a gob of smooth peanut butter. Add some cinnamon. Pour in milk , filling close to the top.
Drop chunks of vanilla or neopolitan ice cream ( we use sugar free because my wife is diabetical) in the second glass until it's close to the top. Pour in milk, filling close to the top.
Dump the first glass in the blender. Run at "smoothie" or higher until smooth.
Add the second glass. Run on "stir" for a few seconds until the ice cream is mostly blended in.
Serves two, unless you want different sized servings.
