Ingredients
Scroll down to the recipe card for the exact ingredient amounts and full recipe details.
- Mixed berries: A triple-berry mix (blueberries, raspberries, blackberries) balances sweetness, tartness, and fiber. Frozen berries produce a colder, thicker smoothie; fresh berries also work.
- Banana: Fresh or frozen banana adds natural sweetness and creaminess. Choose a ripe, spotty banana for the best flavor.
- Natural peanut butter: Look for a simple peanut butter made with just peanuts and salt. Any nut or seed butter (almond, cashew, sunflower) can be used as a substitute.
- Ground flaxseed: Adds fiber and omega-3 fats. Ground flax blends best, though whole flaxseed will blend as well.
- Greek yogurt: Plain Greek yogurt boosts protein without added sugars. Vanilla yogurt can be used for a sweeter result.
- Milk: Dairy milk (2%) adds protein, but soy, almond, or oat milk work as plant-based alternatives. Adjust amount to reach your desired consistency.
How to make a peanut butter berry smoothie
Step 1: Add all ingredients to your blender.
Step 2: Blend until smooth, pour into a glass, and enjoy.
Swaps and additions
- Berries: Any single berry or mixture works — blueberries alone are particularly tasty.
- Other fruit: Try mango, pineapple, grapes, orange slices, or kiwi. Increase your favorite fruits as desired.
- Add sweetness: Add an extra half banana, a medjool date, or a small drizzle of honey for more sweetness. Natural sweeteners like stevia or monk fruit are also options.
- Yogurt: Swap plain for vanilla yogurt for a sweeter profile.
- Vegetables: Add a small handful of baby spinach, kale, grated zucchini, or riced cauliflower for extra nutrients without changing flavor much.
- Nut butter: Swap peanut butter for almond, cashew, or seed butter to vary the taste.
- Seeds: Add chia or hemp seeds for extra fiber and texture.
- Protein powder: If you want more protein, add a scoop of vanilla or unflavored protein powder.
- Coffee: A shot of espresso or a teaspoon of instant coffee pairs nicely with peanut butter for a mocha-style twist.
- Ice: For a thicker smoothie, add a few ice cubes before blending.
Adjust the thickness
Control texture by varying liquid and fruit. For a thinner smoothie, use fresh fruit or extra milk. For a thicker smoothie, use frozen fruit, less milk, or add ice.
Add toppings
Top your smoothie with chopped nuts, a small handful of granola, or a drizzle of extra nut butter for added texture and satisfaction.
Meal prep instructions
This smoothie is best enjoyed within a few hours of blending. If stored too long it can separate and change color.
To prep ahead: Combine ingredients in a sealed container in the fridge and blend right before drinking to preserve texture and color.
Top tips for better blending
- Add liquid first. Pouring milk or liquid in first helps prevent nut butter and flaxseed from sticking to the blender base.
- Adjust liquid as you blend. Add more milk a little at a time until you reach the desired consistency.
- Pause and shake if needed. If the blender stalls, stop, shake or stir, then continue blending.
Common questions
