When the craving for a chocolate milkshake hits, blend this instead. Unsweetened cocoa gives real chocolate flavor, peanut butter makes it rich and creamy, and a frozen banana does all of the sweetening.

A scoop of rolled oats turns it into a filling breakfast or an after-practice snack for hungry teens.

Why It’s Good for You

Peanut butter and soy milk provide protein and healthy fats, oats add slow-burning fiber, and unsweetened cocoa contains flavanols. It’s all of the chocolate flavor without the added sugar of a typical shake.

  3. Blend on high until thick and creamy, about 60 seconds.
  4. Pour into two glasses and top with a sprinkle of cinnamon or chopped nuts, if you like.

Notes

Tips & swaps
  • Want it sweeter? Blend in 1 pitted Medjool date instead of adding sugar.
  • Nut allergy? Use sunflower seed butter instead of peanut butter.
  • Extra protein: add 1/2 cup plain Greek yogurt (no longer dairy-free) for about 6 more grams of protein per serving.
