These Vegan Peanut Butter Oat Cookies are super chewy, full of oatmeal, completely eggless, dairy free and simple to make. 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
Vegan Butter: My preferred brand for vegan butter is Earth Balance. I like the texture, flavor and its easy to find. I typically use Earth Balance's soy-free baking sticks. This keeps these oatmeal cookies dairy-free.
Sugar: Regular granulated sugar, here.
Molasses: For that brown sugar flavor. This adds 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 keeps these oatmeal cookies eggless.
Peanut Butter: I always use natural creamy peanut butter in my recipes. My favorite brand is Teddie. 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.
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.
Method
These cookies are super easy to make.
First, cream together the non-dairy butter, granulated sugar and molasses until light and fluffy.
Then, add the peanut butter and mix to combine.
Next, add the flax egg.
Now, add the dry ingredients and stir until JUST combined.
And thats it!
Then you just scoop, chill and bake!
Storage
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 these cookies is in the freezer. Place the cookies into a freezer bag or airtight container and place in the freezer. These cookies will stay fresh for at least a month!
Just take out one or two 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.
