Many years ago, my friend Sarena shared her favorite peanut butter oatmeal cookies recipe with us. It was adapted ever so slightly from Allrecipes. She says, these cookies are so good that her family of hungry men can devour nearly an entire batch in a day. We decided to give her recipe a try, and have updated this post with new photos, more information, a teensy recipe modification, and several options.
Perfecting Dairy-Free Peanut Butter Oatmeal Cookies
The original recipe is actually for peanut butter oatmeal sandwich cookies. The filling is a peanut butter frosting that’s almost a bit too rich. Instead, I decided to make them Little Debbie style with a vanilla crème filling. Here are a couple other quick notes.
- Salt: I’m not sure if the butter alternatives and peanut butters are getting saltier, but I had to reduce the salt in this recipe a little bit. I’m not known for reducing the salt in recipes (usually the opposite!), but we all noticed a little too much saltiness in the aftertaste when I first tried Sarena’s recipe with the full 1 teaspoon. I do use Country Crock for baking, which is on the salty side (similar to Earth Balance) and a salted peanut butter.
- Oats: These peanut butter oatmeal cookies are quite balanced between the flour, peanut butter, and oats. If you like an oatier finish, go ahead and increase the amount. I do prefer using quick oats though, which cook up better in cookies. Regular rolled oats are a bit too tough for these cookies, but that is a personal preference.
Special Diet Notes: Peanut Butter Oatmeal Cookies
By ingredients, this recipe is dairy-free / non-dairy, tree nut-free, soy-free, and vegetarian. Just be sure to use the butter alternative that suits your dietary needs.
- For peanut-free oatmeal cookies, you can substitute sunflower seed butter for the peanut butter. But note that the cookies might have a slight greenish hue due to the reaction of sunflower seeds with baking soda.
- For egg-free and vegan oatmeal peanut butter cookies, see my Egg Substitution Guide. I would personally use a flax or chia egg, but I haven’t tested this recipe without eggs.
- For gluten-free dairy-free peanut butter oatmeal cookies, I would keep the egg, but substitute your favorite gluten-free baking flour blend. We haven’t tested this recipe without gluten.
- ¾ cup all-purpose flour
- ⅜ teaspoon salt
- ½ teaspoon baking soda
- ¼ teaspoon baking powder
- ½ cup (1 stick) dairy-free buttery sticks
- ½ cup peanut butter
- ½ cup sugar
- ½ cup packed brown sugar
- 1 teaspoon vanilla extract
- 1 egg
- 1 cup quick oats
- Preheat your oven to 350°F and line baking sheets with parchment paper.
- In a medium bowl, whisk together the flour, salt, baking soda, and baking powder.
- In a mixing bowl, cream the butter alternative, peanut butter, sugars, and vanilla. Add the egg and beat well.
- Add the dry ingredients to the wet mixture and stir until combined. Add the oatmeal and stir until combined.
- Drop the dough by the level tablespoon onto your prepared baking sheets. Gently roll each dough piece into a ball, and flatten them to about ¼-inch thick on your baking sheet about 2 inches apart. They will spread just a little.
- Bake the cookies for about 10 minutes, or until cookies are a light brown.
- Let the cookies cool for a few minutes on the baking sheet before carefully transferring them to a wire rack to cool completely. They will be fragile when warm, but firm up s they cool.
