Oat Milk

There are many options on the market these days. Some have a bit of added sugar, others do not. This is good to pay attention to when making your hot chocolate, as it will affect the taste and how much or little sugar you whisk in. 

Many brands make both a sweetened and unsweetened version. For example, Chobani has a Plain Oatmilk with 7 grams of added sugar per cup, as well as a Zero-Sugar Plain version. Planet Oat has an Original version with 4 grams of added sugar per cup, as well as an unsweetened version.

Oatly oatmilks do not use added sweeteners (except in the chocolate version), but you will see added sugar on the Nutrition Facts Label. Their website has a great explanation of why this is. Basically the sugar is produced from the breakdown of the oats in the production process, and the FDA requires manufacturers to list any sugars created in the production process as added sugars.

See notes below recipe for suggestions on sugar to add based on which oat milk you buy.

Cacao Powder

Great option to add that chocolate flavor plus some antioxidants (don’t miss out on our free downloadable Anti-Inflammatory guide on our home page for more info on antioxidants!). 

If you don’t have or can’t find cacao powder, you may use cocoa powder. See FAQ below for more information on the difference between these two.


The amount you use will depend on if you have unsweetened or sweetened oat milk, as well as your taste preferences. See notes below recipe. 

Vanilla Extract

Adds a subtle richness and complexity.


Just a pinch brings the flavors together in the best way.
