Ingredients You’ll Need

These three essential ingredients are all you need to create a smoothie that’s creamy, flavorful, and nourishing. Each ingredient plays a key role in balancing taste and texture to give you that perfect sip every time.

Frozen banana slices: Two cups provide natural sweetness and a creamy texture that makes this smoothie irresistibly smooth.
Peanut butter: Two tablespoons add rich, nutty flavor and a satisfying protein boost; choose chunky or creamy based on your preference.
Organic whole milk: Two cups bring the perfect amount of creaminess and help bind all the flavors together for a luscious drink.

How to Make 3-Ingredient Peanut Butter Smoothie

Step 1: Gather and Prep Your Ingredients

Start by having your frozen banana slices ready—they work best when fully frozen to give this smoothie its thick and frosty texture. Measure out your peanut butter and milk so everything is within easy reach before blending.

Step 2: Blend Until Smooth

Combine the frozen banana slices, peanut butter, and whole milk in your blender. Blend on high speed until the mixture is perfectly smooth and creamy. If your blender struggles, pause and stir to help it along.

Step 3: Portion and Enjoy

Pour your smoothie into glasses—kids will love smaller servings between six and eight ounces, while adults might prefer a generous eight to twelve ounces. This recipe yields about four cups, perfect for sharing or saving a little for later.

Step 4: Optional Boosts (Feel Free to Experiment!)

If you want to sneak in some extra nutrition, consider tossing in a handful of frozen or fresh spinach for a subtle veggie boost that won’t overpower the peanut butter flavor. Or add a tablespoon of cacao nibs for a touch of natural sweetness with a delightful crunch.

How to Serve 3-Ingredient Peanut Butter Smoothie

Garnishes

Elevate your smoothie by topping it with crushed peanuts for extra texture, a drizzle of honey for sweetness, or a sprinkle of cinnamon to add warmth. These little touches not only make it look beautiful but add layers of flavor that make every sip memorable.

Side Dishes

Pair your peanut butter smoothie with crunchy granola bars or fresh fruit slices to round out your snack or breakfast. The creamy smoothie complements light, crisp sides perfectly without overwhelming your palate.

Creative Ways to Present

Serve your smoothie in a mason jar or a tall glass with a colorful reusable straw to make drinking it feel like a treat. You can also layer it in parfait glasses with yogurt and berries for a stunning visual and textural experience that’s as fun to eat as it is tasty.

Make Ahead and Storage

Storing Leftovers

If you have any smoothie left, store it in an airtight container or jar in the refrigerator. For best taste and texture, consume within 24 hours, as separation may happen but a quick stir or shake will bring it back together.

Freezing

You can freeze leftover smoothie in ice cube trays for portioned servings later. Once frozen, transfer the cubes to a freezer bag—blend the cubes with a splash of milk when you’re ready for a quick smoothie fix.

Reheating

Since this is a cold smoothie, reheating isn’t necessary, but if you prefer it less icy, just let it sit at room temperature for a few minutes or give it a quick blend with some fresh milk to loosen it up before drinking.

FAQs

Can I use peanut butter powder instead of regular peanut butter?

Absolutely! Peanut butter powder is a great alternative if you want less fat but still want that peanut flavor. Just rehydrate it with a little water or milk and blend as usual.

Is there a dairy-free option for this smoothie?

Yes! Swap the whole milk with almond milk, oat milk, or any plant-based milk of your choice to keep it creamy without dairy. The smoothie will still be delicious and smooth.

How can I make this smoothie thicker?

Adding more frozen banana slices or tossing in a few ice cubes during blending will thicken the texture. You could also add a spoonful of Greek yogurt for extra creaminess and protein.

Can I add sweeteners to the smoothie?

While the bananas and peanut butter offer natural sweetness, you can add honey, maple syrup, or a bit of agave if you like your smoothie sweeter—just add a little at a time to keep the balance.

What’s the best time to enjoy the 3-Ingredient Peanut Butter Smoothie?

This smoothie is perfect anytime! Breakfast, mid-morning snack, post-exercise recharge, or even a quick dessert—its rich and satisfying flavor fits all moments.
