This is the ultimate summertime smoothie featuring four of nature's best berries, vanilla ice cream and a hint of mint.
Process first 7 ingredients in a blender. Add ice cubes to 4 1/2-cup level; process until smooth, stopping once to scrape down sides. Garnish, if desired; serve immediately.
My dad would have called this a milkshake. Most smoothies I have made do not have ice cream, but maybe sometimes yogurt. However, still tastes great.
