1–2 tablespoons peanut butter
¾ to 1 cup milk of choice (regular milk, almond milk, oat milk, etc.)

How to Make a Peanut Butter Banana Protein Smoothie

Add the banana, protein powder, peanut butter, milk, Greek yogurt, ice, and optional cinnamon or honey to a blender. This is the protein powder I love. Add collage

Blend for about 30–60 seconds until smooth and creamy.

Pour into a glass and enjoy immediately.

Easy Ways to Customize It

Chocolate Peanut Butter Banana Smoothie

Add 1 tablespoon cocoa powder or use chocolate protein powder for a chocolate-peanut butter flavor.

Extra Filling Smoothie

Blend in:

¼ cup oats
1 tablespoon chia seeds
Extra Greek yogurt

Dairy-Free Version

Make It Sweeter

Protein Boost Options

One of my favorite things about protein shakes is how easy they are to customize.

Add Collagen

Collagen peptides blend right into this smoothie without changing the flavor. I often add a scoop for an extra protein boost and an easy way to increase my daily protein intake. This is the collagen I love.

Add Creatine

Creatine is virtually flavorless, making it an easy addition to smoothies and protein shakes. Simply blend it in with the other ingredients. This is my favorite creatine supplement.

Can You Add Both?

Yes! Both collagen peptides and creatine mix well into this recipe, making it an easy, protein-packed breakfast.

Tips for the Best Smoothie

Use frozen bananas for a thicker, creamier smoothie
Start with less milk and add more if needed
Choose a protein powder you actually enjoy the taste of
Blend longer for a smoother texture
