Brew your coffee and let it cool completely in the refrigerator.
Using hot coffee will melt your ingredients and give you a sad, watery mess.
Add the chilled coffee, frozen banana, yogurt, milk, and nut butter to your blender. If you’re using any sweeteners or boosters, toss those in too.
Blend on high until the mixture is completely smooth and creamy. This usually takes about 60-90 seconds.
If it’s too thick, add a splash more milk.
Pour into a glass, add a straw, and enjoy immediately for the best texture and flavor. Congratulations, you’ve just made a weekday feel like a weekend.
