There’s something kind of magical about tossing a handful of blueberries into a blender, adding a scoop of peanut butter, and hitting the switch. The whirr of the blades, the sudden cloud of purple, and that nutty scent—pure smoothie joy. I started making this one morning when I had blueberries on the edge and peanut butter begging to be used. Now? I make it whenever I’m running late, craving something cold, or just want to feel like I’ve made a smart adult choice before 9 AM. It’s sweet without being cloying, creamy without heavy dairy, and just the right balance of fruit, protein, and fiber to keep you moving. There’s no powdered nonsense or mystery ingredients—just the stuff you likely already have in your kitchen. You can make it with frozen blueberries or fresh ones, though frozen gives it a milkshake-like chill that really makes it sing. If your mornings are a blur or your afternoons drag, this smoothie is your edible high-five. We’re blending up something tasty today—let’s do it.
