Notes
Ingredient Substitutions
Milk: Try a plant-based milk with a different flavor, like coconut milk or oat milk.
Peanut Butter: Experiment with almond butter, cashew butter, or even sunflower seed butter for unique flavors.
Protein Powder: For whey or whey/casein substitutions, chocolate whey or cinnamon flavored whey/casein protein powder are great options for this recipe. For plant-based protein powder options, I'd go with a chocolate protein powder (pea protein blend) or peanut butter powder.
Storage InfoThis peanut butter banana shake will stay well for 24 hours after blending if kept in the refrigerator. I like to keep my shakes in thermal tumblers in the fridge and for on the go.
