Ben’s High Protein Cacao Smoothie (Without Protein Powder)

by Ben, So Vegan
Plant Based Vegan High Protein Cacao Smoothie Recipe

This is my tried-and-tested cacao smoothie recipe – and it’s one I spent months perfecting.

It’s rich, chocolatey and naturally sweet – and it also sneaks in 23g of plant-based protein without a scoop of protein powder.

Hemp seeds, walnuts and peanut butter also deliver lots of healthy fats, fibre, and iron too – so it’s both nourishing and delicious.

Tips:

  • Dates: Most high-speed blenders can easily handle a whole date. If yours struggles, soak the date in hot water for 10 minutes, then drain before blending.
  • Banana: Make sure your banana is ripe before freezing – it adds natural sweetness and helps balance the cacao.
  • Milk swaps: Soy milk is great for extra protein, but oat or almond milk also work well if that’s what you have on hand.
  • Nut variations: You can swap the walnuts for almonds or cashews, or use tahini instead of peanut butter for a nut-free version.

Do you have any suggestions for substitutions for a banana allergy?

Banana adds a creaminess, so a dozen or so cashews could work well as long as you have a high-powered blender. You could also add a couple of ice cubes to make it colder.

Why does the banana need to be frozen?

Frozen banana helps chill the smoothie so it’s more refreshing, which we prefer. But I guess it’s personal preference so you don’t have to use a frozen banana if you don’t want to.
