This creamy and refreshing Razzy Blue Smoothie has become one of my favorite mid-morning energizers. Packed with fruit, whole grains, and healthy fats, it is as satisfying as it is delicious. The combination of raspberries, blueberries, and banana gives it a naturally sweet taste that feels like a treat while staying nourishing.
I first made this when I had leftover blueberry packs in the freezer and some almost-too-ripe bananas. Now it is a go-to anytime I want something cool and wholesome in minutes.
