Brew and chill your coffee. Make a small batch of strong coffee or use cold brew.
Let it cool completely so it doesn’t melt the smoothie or taste watered down.
Add base ingredients to the blender. Start with the banana, coffee, milk, and nut butter. This creates a smooth blend and helps the blades catch everything.
Layer in flavor. Add vanilla and a pinch of cinnamon. Include sweetener if your banana isn’t very ripe or you prefer a sweeter smoothie.
Boost if you want more nutrition. Add oats for thickness, protein powder for staying power, or cocoa for a mocha vibe.
Seeds add fiber and healthy fats.
Blend until creamy. Start low, then go high for 30–45 seconds. If it’s too thick, splash in more milk. If it’s too thin, add a few ice cubes or extra frozen banana.
Taste and adjust. Need more coffee flavor?
Add a little more chilled coffee. Want it sweeter? Add a touch more honey or maple syrup.
Serve cold. Pour into a chilled glass or a to-go cup.
Top with a sprinkle of cinnamon or cocoa if you like.
