The Smoothie That Actually Fills You Up
If you've ever blended a "protein smoothie" and felt hungry again an hour later, the problem is usually the protein source. Most powders are packed with gums, sweeteners, and filler that your gut doesn't love — especially if you have IBS or a sensitive stomach.
This peanut butter protein smoothie is different. Built around That Protein's Nutty Nutty Peanut Butter Super Protein — a Low FODMAP Friendly, additive-free blend made with organic peanut protein, organic pea protein, organic chia protein, and Palmyra Jaggery — it delivers 26g of plant protein, real peanut butter flavour, and a creamy texture that keeps you satisfied. No artificial anything.
Base Recipe: Nutty Nutty Peanut Butter Protein Smoothie
This is the hero. Thick, creamy, and built on Nutty Nutty Peanut Butter Super Protein — winner of "Best Protein" at the Nourish Awards 2018, and the go-to choice for anyone following a low FODMAP or plant-based lifestyle.
Ingredients
- 2 scoops (60g) Nutty Nutty Peanut Butter Super Protein
- 1 medium frozen banana (peeled and frozen overnight)
- 250ml oat milk or other low FODMAP plant milk (see tips below)
- 1 tbsp peanut butter (optional, for extra richness)
- 1 tsp maple syrup (optional)
- Small handful of ice
Method
- Add the frozen banana and plant milk to your blender first — this helps the blades move freely.
- Add both scoops of Nutty Nutty Peanut Butter Super Protein.
- Add peanut butter and maple syrup if using.
- Blend on high for 30–45 seconds until completely smooth.
- Taste and adjust: add more milk to thin, or a few extra ice cubes to thicken.
- Pour and drink immediately for the best texture.

3 Variations to Mix It Up
Variation 1: Chocolate Peanut Butter Smoothie
Uses: Blissful Brown Rice & Raw Cacao Protein
What changes: Replace one scoop of Nutty Nutty with one scoop (25g) of Blissful Brown Rice & Raw Cacao. Keep the frozen banana, plant milk, and optional tablespoon of peanut butter.
Why it works: Blissful is FODMAP Friendly certified by FODMAP Friendly and made with just two ingredients — organic brown rice protein and organic raw cacao. The deep, bitter chocolate cuts through the sweetness of the banana and layers beautifully with the peanut butter flavour. Think chocolate-dipped peanut butter cup, in a glass.
Variation 2: Mocha Peanut Butter Smoothie
Uses: Chirpy Chirpy Choca Mocha Protein
What changes: Replace one scoop of Nutty Nutty with one scoop (25g) of Choca Mocha. Add an extra handful of ice and blend until frothy. For an iced-coffee style finish, pour over a tall glass of ice.
Why it works: Choca Mocha combines organic brown rice protein, organic raw cacao, and freeze-dried organic coffee into a Low FODMAP mocha blend. Paired with the nutty depth of Nutty Nutty, it's a grown-up, energising smoothie that doubles as a pre-workout. Note: contains caffeine — not suitable during pregnancy or for children.
Variation 3: Double Choc Peanut Butter Smoothie Bowl
Uses: Double Choc Protein Porridge
What changes: Use 60g of Double Choc Protein Porridge instead of protein powder. Reduce milk to 150ml and blend until thick — the oats give it a texture closer to soft-serve than a drinkable smoothie. Pour into a bowl and add toppings: sliced banana, a swirl of peanut butter, cacao nibs, or a few dark chocolate chips.
Why it works: Double Choc Protein Porridge is FODMAP Friendly certified by FODMAP Friendly and made with organic oats, plant protein, raw cacao, cacao nibs, and Palmyra Nectar. The oats thicken the blend into a rich, spoonable smoothie bowl — 13g protein, 8g fibre, and zero artificial anything. It's a genuinely satisfying breakfast bowl that looks as good as it tastes.
Tips for the Best Low FODMAP Peanut Butter Protein Smoothie
Low FODMAP milk options: - Oat milk — use in moderate amounts (around 250ml); large servings can be high FODMAP, so check your tolerance - Rice milk — naturally very low FODMAP and a great neutral base - Lactose-free cow's milk — works perfectly if you're not fully dairy-free - Hemp milk — low FODMAP and adds a subtle nuttiness that pairs well with peanut butter - Avoid regular cow's milk, soy milk (whole soy), and large amounts of almond milk if following a strict low FODMAP protocol
Freeze your bananas in advance: Peel ripe bananas, break into chunks, and freeze in a zip-lock bag. Frozen banana gives the smoothie a thick, creamy texture without needing ice cream or yoghurt — and natural sugars in a ripe banana are lower FODMAP than many sweeteners.
Protein powder tip: Nutty Nutty's Low FODMAP serving is 21g (one scoop). The base recipe uses 60g across two servings or as a post-workout blend. Adjust to your own portion needs and tolerance.
Make it thicker or thinner: - Thicker: reduce milk to 150ml and add extra frozen banana - Thinner: add milk gradually until you reach the consistency you want - Extra cold: freeze your blender cup for 10 minutes before blending
Storage: Best consumed immediately. If needed, store in a sealed jar in the fridge for up to 24 hours and re-shake or re-blend before drinking.
