    Banana Peanut Butter Oatmeal Smoothie

    Published: Aug 26, 2022 · Modified: Jul 10, 2025 by Marinela Malcheva


    Jump to Recipe

    This Banana Peanut Butter Oatmeal Smoothie is a quick and easy vegan shake made with creamy oat milk, rolled oats, ripe banana, and a swirl of peanut butter - perfect for breakfast, a snack, or a post-workout drink.

    Naturally sweet, filling, and made without yogurt, it’s a cinnamon-spiced treat that tastes like dessert in a glass!

    This banana peanut butter oatmeal smoothie is my go-to when I need a quick yet nourishing breakfast, especially on busy mornings when I haven’t prepped anything overnight.

    I honestly make it so often because it’s just that reliable: creamy, filling, and energizing enough to power me through my day.

    Just like my apple oatmeal smoothie, date tahini smoothie, or high-protein date shake, this smoothie is cold, refreshing, and thick with the most satisfying texture.

    The best part? It comes together in minutes using pantry staples you probably already have, no fancy ingredients, no yogurt, just pure plant-based goodness in a blender!

    🍌Ingredients and Substitutions

    Banana peanut butter oatmeal smoothie ingredients.
    • Rolled oats: Make the smoothie thick and satisfying (quick oats work too).
    • Banana: Adds natural sweetness and creaminess—frozen banana makes it extra cold.
    • Peanut butter: Brings rich flavor and keeps you full—feel free to use any nut or seed butter.
    • Ground flaxseed: Helps make it more filling—chia or hemp seeds are great substitutes.
    • Oat milk: Keeps it smooth and dairy-free. Any dairy-free milk, such as almond milk or cashew milk, will work.
    • Maple syrup: Just a touch for extra sweetness. Use dates or skip if your banana is sweet enough.
    • Cinnamon: Adds cozy flavor. Pumpkin spice or vanilla are fun swaps.

    As always, you can find the full recipe with a list of ingredients with measurements in a printable recipe card at the end of this post.

    📋Variations

    • Oatmeal coffee smoothie: Add a shot of chilled espresso or strong brewed coffee for an energizing breakfast smoothie that tastes like a peanut butter latte.
    • Oatmeal blueberry smoothie: Toss in a handful of fresh or frozen blueberries for a fruity twist and a beautiful purple hue.
    • Oatmeal chocolate smoothie: Add 1 tablespoon of unsweetened cocoa powder or chocolate protein powder for a rich, dessert-like shake.
    • Oatmeal protein smoothie: Add a scoop of your favorite plant-based protein powder to make it a post-workout smoothie that keeps you fuller for longer.
    • Green oatmeal smoothie: Add a small handful of baby spinach. You won’t taste it, but it gives your smoothie a nutrient-packed green glow!

    💡Marinela's Tips

    • Blend oats first: If you don’t have a high-speed blender, blend rolled oats alone first, then add the rest and blend until creamy.
    • Freeze bananas properly: Peel and slice bananas, freeze them spread out on a tray, then store in a bag for quick, smooth blending.
    • Sweeten to taste: Adjust maple syrup or your favorite sweetener to get just the right sweetness.
