These Vegan Peanut Butter Oat Cookies are completely eggless, dairy free and simple to make. Plus, these vegan cookies are super chewy from the oatmeal and full of peanut butter flavor. A definite crowd-pleaser!
These Vegan Peanut Butter Oat Cookies were a special request of my husband. He loves both peanut butter and all oat cookies, so why not combine them? And boy these are tasty. These vegan cookies are super chewy and moist thanks to the oatmeal and are full of peanut butter flavor.

Ingredients for Making Eggless and Dairy Free Peanut Butter Oatmeal Cookies
Dairy Free Butter: My preferred brand for dairy free butter is Earth Balance. I like the texture, flavor and its easy to find. I typically use Earth Balance's soy-free baking sticks. Using non dairy butter makes these oatmeal peanut butter cookies totally dairy free!
Sugar and Molasses: If you've been around here for a while, you know that I don't buy brown sugar for a couple of reasons. First, is I have a small kitchen and space is scarce. Second, is that I always have granulated sugar and molasses on hand. And those are the ingredients that make brown sugar. So, I simply make brown sugar in the recipes by adding molasses to granulated sugar and it works perfectly every time. This combination add so much warm flavor the these Vegan Peanut Butter Oat Cookies.
Flax Egg: A flax egg is used for binding, just as a regular egg. To make a flax egg, combine ground flax and water and allow the mixture to thicken. Using a flax "egg" to bind keeps these oatmeal cookies eggless.

Peanut Butter: I always use natural creamy peanut butter in my recipes. My favorite brand is Teddie, but its local to the Boston area and is likely hard to find elsewhere. A peanut butter that has a comparable texture is Smuckers Natural Creamy Peanut Butter.
Old Fashioned Rolled Oats: Don't substitute minute oats or instant oats here. They absorb differently than rolled oats. The rolled oats make these vegan peanut butter oat cookies soft and super moist and chewy.
All Purpose Flour: Flour helps bind everything together and adds to the chew. Don't sub GF flour in these Vegan Peanut Butter Oat Cookies! When baking gluten-free, its best to use recipes that are designed to be gluten free.

How To Store Cookies for Freshness
I make a LOT of baked goods. Far too many for a person (or even two!) to consume if they are stored on the counter. So, my favorite way to store them is in the freezer. In the freezer, these Vegan Peanut Butter Oat Cookies will stay fresh for at least a month!
Just toss them into a bag or a container and just take out one or two or however many you feel when the craving strikes.
My favorite way to warm them up after they they have been frozen is in the toaster oven but a microwave works well too!
