Why You’ll Love My Homemade Plant Milk

You’re going to love my chocolate oat milk recipe because it uses simple pantry ingredients, it’s loaded with chocolate flavour, and most importantly – it’s not slimy! (Unlike many recipes I’ve tried on the web).

After perfecting my Classic Oat Milk Recipe and Oat Milk Coffee Creamer, I’ve cracked the code for silky-smooth, ultra-rich, and flavourful oat milk – without the dreaded slime!

And, we’re taking it up a flavour notch with this Homemade Chocolate Oat Milk. It’s ultra creamy (thanks to the cashews) and naturally sweetened with maple syrup. All in all, this is the perfect chocolate oat milk for sipping, blending into smoothies, or pouring over your morning chocolate oatmeal porridge.

Let’s get into the details so you can make this homemade oat milk in just 15 minutes!

Ingredient Notes

Making homemade chocolate oat milk requires just 6 simple ingredients:

Cashews – When making any plant-based milk, always use raw cashews. Roasted or seasoned cashews have a strong flavour and will overpower the flavour of the final milk. In my recipe testing the flavour did not turn out as nice with roasted cashews.
Rolled oats – For the creamiest texture I recommend using old-fashioned rolled oats. I recipe tested this with quick cooking oats, but they lead to a slimy milk. Steel-cut oats will be too gritty and hard to break down in 30 seconds.
Cocoa powder – The key ingredient for a rich, deep chocolate flavour! Avoid sweetened varieties of cocoa powder – the only ingredient should be unsweetened cocoa or cacao powder.
Coconut oil – In my recipe developing I discovered that a little bit of oil helps create the silkiest, creamiest texture. If you don’t love the flavour of coconut, use refined coconut oil or another neutral oil such as avocado oil.

How to Make Chocolate Oat Milk

Start to finish, this chocolate oat milk is ready in under 15 minutes!

To start, soak the cashews in hot water for 10 minutes before straining. This helps create a smoother texture and shortens the blend time (which is very important when making oat milk!). I still do this even though I’ve invested in a high speed Vitamix blender!

Serving Suggestions

We love to drink this homemade chocolate oat milk chilled over ice, but it can be swapped with traditional oat milk in several of my favorite recipes for a chocolate-y boost!

Add it to Chocolate Chia Pudding or Chocolate Overnight Oats.
Blend it into a Banana Chocolate Smoothie or Chocolate Avocado Smoothie.
Stir it into waffle or pancake batter for a chocolate twist!
