Peanut protein sea moss shake beside banana, peanut butter, oats and sea moss gel.

This peanut butter protein sea moss shake is creamy, filling, and easy to make. It combines simple ingredients — banana, peanut butter, milk, protein powder, and sea moss gel — into a smooth, satisfying drink that works well as breakfast, after exercise, or as a mid-afternoon pick-me-up.

No complicated steps or unusual ingredients. Just a blender and a few minutes.

Why this shake works so well

Peanut butter brings richness and a creamy texture, while ripe banana adds sweetness and body without added sugar. Protein powder makes it more filling, and sea moss gel blends quietly in the background — you won't really taste it.

If you're new to sea moss and unsure about the flavour, this is a great starting point. Peanut butter and banana are bold enough to carry the shake, while the sea moss blends in smoothly.

Ingredients

  • 1 ripe banana
  • 1 tablespoon sea moss gel
  • 1 tablespoon peanut butter
  • 1 scoop vanilla or unflavoured protein powder
  • 1 cup oat milk, almond milk, dairy milk, or your preferred milk
  • ½ teaspoon cinnamon, optional
  • 1 teaspoon maple syrup or honey, optional
  • A few ice cubes, optional

How to make it

  1. Add the banana, sea moss gel, peanut butter, protein powder, and milk to a blender.
  2. Add cinnamon and sweetener, if using.
  3. Add ice cubes for a colder, thicker shake.
  4. Blend until smooth and creamy.
  5. Taste and adjust the sweetness, or add a splash more milk if needed.
  6. Pour into a glass and enjoy straight away.

A few tips before you blend

The riper your banana, the sweeter your shake — no extra honey needed. Vanilla protein powder pairs well with peanut butter, but unflavoured works just as nicely. If the shake is thicker than you'd like, add a little more milk and blend again.

How much sea moss gel should you use?

This recipe uses 1 tablespoon of sea moss gel. A common daily serving is 1–2 tablespoons, but check the guidance on your product label, as this can vary.

More isn't always better. Sea moss contains minerals, including iodine, so use it in reasonable amounts as part of a balanced diet.

Can you make this shake vegan?

Yes, easily. Use plant-based milk, vegan protein powder, and swap honey for maple syrup if you want extra sweetness. Most plain sea moss gels are plant-based, but check the label on flavoured versions, as some may include honey or other additives.

Can you make it nut-free?

You can, but you'll need to swap out the peanut butter. Sunflower seed butter or tahini can work as alternatives. The flavour will be a little different, but the shake should still blend smoothly.

If you're making this for someone with a nut allergy, check every ingredient carefully and be mindful of cross-contamination risks.

What if you don't have protein powder?

No problem. The shake will still be creamy and filling from banana, peanut butter, and milk. If you'd like more protein without powder, a spoonful of Greek or plant-based yoghurt works well, or add an extra tablespoon of peanut butter.

Simple ways to change it up

Chocolate peanut shake

Add 1 tablespoon of cacao powder for a rich, chocolatey version.

Extra creamy

Use oat milk or coconut milk, and stir in a spoonful of yoghurt before blending.

Berry peanut shake

Add a handful of strawberries or blueberries for a fruitier flavour.

Cinnamon banana shake

Double the cinnamon and add a little vanilla extract for something closer to a dessert shake.

Smoothie bowl

Use less milk, pour into a bowl, and top with sliced banana, rolled oats, crushed nuts, or cacao nibs.

Can you make it ahead of time?

This shake is best fresh, straight from the blender. If you prep it ahead, keep it covered in the fridge and drink it as soon as possible. It may thicken or separate as it sits, so stir or shake before drinking.

A note on sea moss

Sea moss is a natural ingredient that many people enjoy as part of a balanced diet and wellness routine. It's not a substitute for medical advice, and it may not be suitable for everyone.

If you are pregnant, breastfeeding, taking medication, managing a thyroid condition, or using iodine supplements, please speak with a qualified healthcare professional before adding sea moss to your routine.

Final thoughts

This peanut butter protein sea moss shake is a simple way to blend sea moss gel into something creamy, familiar, and filling. With banana, peanut butter, milk, and protein powder, it feels more like a proper shake than a wellness task.
