  • 1 cup brewed coffee
  • 1 cup milk
  • cup quick oats
  • 1 frozen banana
  • 1 tablespoon honey (optional)
  • cup Greek yogurt


  • Place all of the ingredients into a blender.

  • Use a frozen banana for this smoothie. Using a frozen banana eliminates the need for need for ice which can water down the smoothie.
  • Use over ripe bananas. Smoothies are a great way of using up bananas, if you have bananas that are about to go off, pop the in the freezer and they are great to grab for a smoothie. Over ripe bananas have more natural sweetness as well as more antioxidants.
  • Use warm or cold coffee: You can used brewed coffee or instant, but let it cool before adding it to the mixer, it shouldn't be boiling hot. If you are in a hurry pop it in the freezer for a few minutes or make it ahead of time.
  • If you do make the smoothie ahead of time, give it a good stir before drinking it because the ingredients may have settled and separated.
  • Optional add ins: If you want to amp your coffee smoothie up a another notch, try adding 1 teaspoon of cocoa powder or a couple of tablespoons of coconut flakes.
