Peanut Butter Banana Smoothie
This peanut butter banana smoothie is thick, creamy, and naturally sweet from frozen bananas. I blend six core ingredients—including Greek yogurt and nutrient-dense ground flax—for a spoonable 10-minute breakfast or snack with 12g of protein per serving.
Why You’ll Love This Smoothie
- Thick and Creamy: Frozen bananas, Greek yogurt, and natural peanut butter create a milkshake-like texture that is thick enough to eat with a spoon.
- Six Core Ingredients: The tested recipe keeps the ingredient list short while ground flax adds extra nutrients.
- 12g Protein Per Serving: Greek yogurt, peanut butter, and flax help make this a satisfying breakfast or snack.
- Ready in 10 Minutes: Add everything to a high-speed blender, blend until smooth, and serve immediately.
- Frozen Bananas: Use sliced frozen bananas for the tested thick, cold texture. If you cannot find them at the store, freeze bananas at home.
- Greek Yogurt: Nonfat Greek yogurt adds creaminess, tang, and protein. Plain or vanilla Greek yogurt both work; the flavor and nutrition will vary by brand.
- Ground Flax Seeds: Flax is a nutrient-dense core ingredient in this smoothie, not an optional add-in.
- Unsweetened Almond Milk: Almond milk supplies the liquid needed to blend. Another milk may be used, but it can change the flavor, thickness, and nutrition.
- Vanilla Extract: Vanilla rounds out the banana and peanut butter flavors.
- Natural Peanut Butter: Creamy natural peanut butter adds salty-sweet flavor, richness, and protein.
Tips for a Thick Smoothie
- Use Frozen Bananas: They chill and thicken the smoothie without ice, which can dilute the flavor.
- Load the Blender Thoughtfully: Put the almond milk and yogurt near the blades before adding the remaining ingredients and frozen banana.
- Adjust Slowly: If the mixture is too thick for your blender, add a small splash of milk and blend again. Stop when it is smooth but still spoonable.
- Serve Immediately: This smoothie has its best cold, thick texture right after blending and is not intended for make-ahead storage.
Tested Add-Ins and Toppings
The six ingredients in the recipe card make the base smoothie. I have also tested the following additions, and each is delicious. Keep in mind that add-ins can change the smoothie’s texture and nutrition.
- For More Protein: Add your favorite protein powder or collagen powder.
- For Greens: Blend in kale or spinach.
- For Texture: Top with peanuts or mini chocolate chips.
- For Extra Peanut Butter: Finish with a drizzle of natural peanut butter.
This smoothie is especially good served thick with a spoon. You can also use it as the base for a smoothie bowl and add your favorite toppings.
