High-Protein Banana Peanut Butter Coffee Smoothie

Prep Time: 5 minutes
Blend Time: 1 minute
Servings: 1 large smoothie

Ingredients

1 medium frozen banana
1 cup cold brewed coffee or chilled coffee
¾ cup plain Greek yogurt
1 scoop vanilla or chocolate protein powder
1 tablespoon peanut butter
½ teaspoon ground cinnamon
½ teaspoon vanilla extract
½ cup ice cubes
1–2 teaspoons honey or maple syrup, optional
1 banana slice for garnish, optional

Instructions

Brew the coffee in advance and allow it to cool completely. Hot coffee will melt the frozen banana and ice, making the smoothie thin.
Add the cold coffee, Greek yogurt, protein powder, frozen banana, peanut butter, cinnamon, vanilla extract, and ice cubes to a high-powered blender.
Blend on high for 45–60 seconds or until the mixture becomes completely smooth, thick, and creamy.
Stop the blender and check the consistency. Add a small splash of milk or coffee if the smoothie is too thick.
Taste the smoothie. If you prefer it sweeter, add honey or maple syrup and blend for another few seconds.
Pour the smoothie into a large glass or clear serving cup.
Garnish the rim with a fresh banana slice and serve immediately with a reusable straw.

Tips

Slice and freeze the banana overnight for the thickest, creamiest smoothie.
Use decaffeinated coffee if you want to enjoy it later in the day.
Add one teaspoon of cocoa powder for a chocolate-mocha flavor.
For extra fiber, blend in one tablespoon of chia seeds or ground flaxseed.
Use powdered peanut butter to reduce calories while retaining the peanut flavor.
For an even thicker smoothie, reduce the coffee to ¾ cup.
Always cool freshly brewed coffee before adding it to the blender.
Choose a protein powder you enjoy because its flavor will be noticeable.

Variations

Chocolate Banana Coffee Smoothie

Add one tablespoon of unsweetened cocoa powder and use chocolate protein powder.

Oatmeal Breakfast Smoothie

Add ¼ cup rolled oats and blend until completely smooth.

Dairy-Free Version

Use plant-based protein powder, dairy-free yogurt, and almond, oat, or soy milk if additional liquid is needed.

No-Coffee Version

Storage

This smoothie tastes best immediately after blending. If necessary, pour it into an airtight container and refrigerate it for up to 24 hours.

The smoothie may separate while refrigerated. Shake or stir it thoroughly before drinking. Freezing the prepared smoothie is not recommended unless it is being made into smoothie pops.
