Have you heard of oat milk? I thought it was pretty common but my pediatrician asked what kind of milk my baby drinks (he drinks both whole milk and oat milk) and both her and the nurse had no idea what I was talking about and thought I said oak milk. I am pretty sensitive to lactose so I use this in my coffee in the morning and have been looking for a more sustainable option. Did you know milk cartons are not recyclable most places because the cardboard is too hard to separate from the plastic coating on the inside?

I love oat milk! It’s richer than regular milk and adds an amazing taste to my morning mocha. The homemade version is thinner than the stuff you buy from the store (less additives), so that does take some getting used to.

I hate cleaning the blender, so I usually make this in a double batch so I have to make it less often. You can play around with the maple syrup and vanilla extract to your desired taste. I also decided to get extra fancy with this one and use my favorite Weck jars.

Oat Milk Recipe

The recipe is super simple. You just have to mix it all together. Many recipes cautioned about different ways the milk can become slimy (more like oatmeal). I have not had that problem at all. I think it’s because I bought a nut milk bag instead of just using a strainer. You are supposed to let most of it fall out on its own and just give it a gentle squeeze. If you over squeeze it, you will start to get the oats and it may become slimy.

Why Choose Oat Milk?

Oat milk is an excellent alternative to regular milk. I chose oats over almond milk as it has less of an environmental impact (almonds are harder to grow). Let’s hope this trend catches on!
