Nutrition For Mental Health
Cacao powder is an excellent source of antioxidants, selenium, magnesium, manganese, and chromium. However, these minerals usually aren’t on nutrition labels. Cacao also contains small amounts of calcium, iron, and potassium.
Let me tell you, learning about how food can impact your mood is so fascinating! That’s why I got my Master of Science in Human Nutrition and Functional Medicine. Let’s chat about cocoa. Cocoa-rich foods have been shown to improve mood while reducing symptoms of depression and anxiety.
Ingredients + Notes

- Oat milk: I always recommend using unsweetened oat milk. This way, you have full control over how sweet this hot chocolate with oat milk is.
- Cacao powder: I always opt for organic cacao powder. It is rich and full of flavor!
- Maple syrup: My go-to sweetener (especially when using it in a liquid). It dissolves perfectly into the hot chocolate mix.
Substitutions + Variations
This healthy oat milk hot chocolate is perfection as is. With a three-ingredient recipe, there aren’t many changes that can be made. However, here are some options if needed.
- Milk: If you can only find sweetened or vanilla oat milk, either works just fine. However, keep in mind that you will most likely want to omit the maple syrup or reduce it. Alternatively, almond milk, soy milk, cashew milk, or hemp milk will all work as well. With these dairy-free milk alternatives, you may feel the need to increase the amount of sweetener.
- Sweetener: I always opt for maple syrup when it comes to sweetening a liquid. That being said, agave works well too. Alternatively, cane sugar is a good option for a neutral sweetness. Finally, for a sugar-free option, stevia or monk fruit sweetener is your best bet!

FAQ

This really depends on personal preference. Oat milk is naturally sweeter, so if you want to minimize the amount of added sugar, then oat milk is a great option. However, if you have almond milk on hand or you simply prefer it, then it will taste good, too!
Yes, oat milk is good for hot drinks. You can heat it on the stovetop over medium heat, or you can pour it into a microwave-safe mug and microwave it for one to two minutes.
