Add the 1½ cups cold brew coffee, 1 medium banana, 2 tablespoons nut butter, ¾ cup unsweetened Greek yogurt, 5-6 whole, pitted Medjool dates, 1 pinch salt, 1 serving protein powder and ½ cup ice to a blender and blend until smooth.
While blending, mix together 2 tablespoons peanut butter and 2 tablespoons maple syrup to make a faux "caramel" sauce, if desired.
Pour the smoothies into glasses and top with peanut butter caramel.
Serve immediately or store for later!
Notes
You can use ripe bananas instead of frozen bananas if you prefer. Just add some extra ice to thicken the smoothie.Use any nut butter such as peanut butter, almond butter, cashew butter or sun butter.
