This smoothie came out of a low-groceries, no-time kind of morning and honestly, it's been on repeat ever since. I threw together a banana, soy milk, a spoonful of peanut butter, and frozen berries, and somehow ended up with a thick, creamy, peanut-butter-and-jelly milkshake vibe. Total win.
Now it's my go-to for busy mornings, long days, or whenever I need something quick, filling, and actually nourishing. It's sweet-but-not-too-sweet, packed with fiber, and super satisfying.
If you're into fruity smoothies that actually keep you full, you'll love this one-and maybe a couple of my other faves too. Try my Sweet Potato Superfood Smoothie if you want something lush, zingy, and antioxidant-packed. Or, for a spoonable option, my Coconut Raspberry Pomegranate Chia Pudding is creamy, naturally sweet, and perfect for make-ahead mornings.
🥣 Ingredients You'll Need
- 300 - 350 millilitres non-dairy milk - I love oat milk for extra creaminess, but soy or almond work beautifully too.
- 1 medium ripe banana - Fresh or frozen both work-frozen gives an ice-cream-like texture.
- ½ cup frozen mixed berries - Any combo of berries will do! I usually go for blueberries, raspberries, or blackberries.
- 1 tablespoon smooth peanut butter - Adds richness and a boost of plant-based protein. Swap for cashew or almond butter if needed.
- ½ tablespoon rolled oats - For a thicker, more filling smoothie.
- 1 teaspoon chia seeds - They add fiber, omega-3s, and help thicken the smoothie to be more meal like.
Blender Recommendation
I always say-use the best blender you can afford. I upgraded to a Vitamix back in 2019, and honestly? Total game changer. Smoothies, sauces, soups… everything blends into the silkiest, velvety dream. If you're blending often (especially fibrous things like oats or chia seeds), that power makes all the difference.
If you're short on space or want something smaller but still strong, I would recommend the NutriBullet 900w or the Pro 1200W or a Ninja personal blender Both are compact, quick, and great for single servings. Just let your frozen fruit thaw for a minute or two before blending for best results.
How to make:
In three easy steps you will have a satisfying berry packed smoothie:
- Pop all your ingredients into a blender-milk, banana, berries, oats, and peanut butter.
- Blend on high until smooth and creamy - scraping down the sides if needed.
- Pour into your favourite glass or bottle and serve immediately with ice, or chill in the fridge until you're ready to sip.
🔁 Smart Swaps and Substitutions:
Protein Add-Ins: Add a scoop of your favorite vegan protein powder, a spoonful of hemp seeds, or a tablespoon or 2 of silken tofu to make it more filling.
Greens? Yes please. A small handful of baby spinach or kale blends right in-no weird taste, just extra goodness.
Creamier texture? Use a frozen banana and chilled milk.
Nut-free? Use sunflower seed butter or tahini.
Low-Sugar Option: Use unsweetened non dairy milk and opt for blueberries or blackberries, which are lower in sugar than other berries.
🧊 Texture & Consistency Tips
- Too Thick? Add a splash more non-dairy milk and blend again until you reach your ideal sip-able consistency.
- Too Thin? Toss in a few extra frozen berries or a couple of ice cubes to thicken things up without messing with the flavor.
