In this article – we share a tasty oat milk protein shake recipe that’s vegan and dairy-free (with optional ingredient upgrades so you can tailor it to your preferences).

Oat Milk Protein Shake Benefits

For such a simple recipe, this shake certainly packs a nutritional punch. The base combo is made using oat milk and vanilla protein powder, both of which are fortified with healthy vitamins and minerals. You’ll see we’ve also included lots of extra ingredient ideas further down, so you can tailor the recipe with different fruits, nut butters, or spices.

Let’s take a closer look at the benefits of the basic ingredients to begin with…

  • Oat Milk – Oat milk is a nutritious dairy-free alternative that offers a creamy texture and a subtle sweetness. It’s a great source of fibre, vitamins, and minerals, including calcium and iron. It’s also the most environmentally-friendly plant-based milk to produce.
  • Vanilla Protein Powder – Protein powder provides the necessary amino acid building blocks for muscle repair and growth. It also helps you feel fuller for longer, making it an excellent addition to your shake. Vanilla-flavoured protein powder is a delicious option for your healthy shake, while also being neutral enough to pair well with any other ingredients you might want to add.
