👩‍🏫 Pro Tips

  • Use frozen banana – It makes the smoothie thick and cold without needing too much ice.
  • Start on low speed in the blender to help it mix smoothly, then crank it up.
  • Don’t skip the yogurt – it adds creaminess and protein.
  • Taste before adding sweetener – the banana might make it sweet enough!
  • Make coffee ice cubes if you want even more coffee flavor.

🔧 Tools You’ll Need

  • Blender
  • Measuring cups and spoons
  • Tall glass or to-go cup
  • Straw (optional, but fun!)

🔁 Substitutions and Variations

  • No cold brew? Use chilled leftover brewed coffee.
  • Dairy-free? Use a plant-based yogurt like almond or coconut.
  • Nut-free? Try sunflower seed butter.
  • Add-ins: chia seeds, oats, or cocoa powder for a twist.

⏱️ Make Ahead Tips

You can freeze the banana in slices the night before and have your ingredients portioned and ready in the fridge. Blend in the morning!

⚠️ Common Mistakes
