What You’ll Need

  • ¼ tsp cinnamon (optional)
  • ½ cup ice

Pro Tips

  1. Use frozen banana – It makes the smoothie extra creamy without needing extra ice.
  2. Chill your coffee – Hot coffee will melt the ice and thin out the smoothie.
  3. Add more protein – A scoop of vanilla or chocolate protein powder blends right in.
  4. Sweetness level – Adjust honey based on how sweet you like it (or skip it if your banana is really ripe).
  5. Blend in stages – Start on low to break up the ice, then blend on high for the smoothest texture.

Tools You’ll Need

  • Blender
  • Measuring cups & spoons
  • Knife (to cut banana if needed)

Substitutions & Variations

  • No banana? Swap it for ½ cup Greek yogurt + extra ice.
  • Dairy-free? Use almond, oat, or coconut milk.
  • No peanut butter? Try almond butter or sunflower seed butter.
  • More coffee flavor? Add ½ tsp instant coffee for an extra kick.
  • Chocolate twist? Toss in 1 tbsp cocoa powder.

Make-Ahead Tips

  • Pre-portion bananas in freezer bags for quick grab-and-blend mornings.
