This peanut butter oatmeal cookie recipe will satisfy your sweet tooth dessert cravings for sure! If you’re looking for a new homemade cookie this is it.
My youngest daughter made this peanut butter oatmeal cookie recipe when we were craving something a bit sweet one night. Use either a subtle hint or load up the peanuts and I bet y’all will love them too. (affiliate links present)
- Years ago we made these peanut butter cookie brownies and they were just over the top I tell you.
They weren’t really homemade as we used cake mix as the base, so we thought we’d integrate Old Fashioned oats this go around.
If you don’t cook or bake with kids currently I would encourage you to do so with this great recipe. It is a life lesson they’ll need forever more and measurements can be sort of a math lesson (but they won’t realize it).
I do like to use a mixer for these. Yes I do have a big upright KitchenAid but let me tell you how much I love this one. It fits right under my counter with a lid that has a hole for adding all the things in it when you need to. Inexpensive too!
- Space is always key too. I hate cluttering up my kitchen counter so anything that is small and fierce I just have to share.
- It has an ice cream maker attachment too so it’s 2 appliances in 1!
- This one is super simple for kids to work with too with just one setting in the front to turn it low to high.
Peanut butter oatmeal cookie recipe
- Mixer or 2 large bowls
- Old Fashioned oats
- Creamy peanut butter
- I wouldn’t use natural peanut butter
- You could use crunchy peanut butter
- Brown sugar
- All purpose flour
- Baking soda and salt
And a non stick baking sheet so you can allow them to cool just like we do with our best ever peanut butter cookies recipe.
You could easily fold in 1/2 cup of mini chocolate chips at the end too. That is on our list for next time. I think the key to any cookie with add ins is to mix all the ingredients together and then fold in what might break apart.
Oats go in last for us on this one. Chocolate chips and/or raisins would go in last too.
What is a substitute for eggs in peanut butter cookies?
- If you need an egg free cookie recipe you can also use applesauce instead. Substitute 1/4 cup applesauce for one egg in the cookie recipe.
- This tweak will give the cookie dough moistness and impart the cookies with great flavor.
The only other difference is they may not puff up as you would normally expect, they’re a bit denser if you ask me.
Homemade peanut butter cookies
- Mix together wet ingredients in a bowl
- If you want an intense peanut butter flavor add 3 tbsp, for “regular” add 2
- In a separate bowl blend together dry ingredients and then slowly integrate the two
- Gently fold in oats and any other add ins you’d like
- If you chill the dough in the fridge for an hour or so they will maintain a more uniform shape when baked golden brown
- Take off cookie sheet and transfer to cooling rack so they can cool completely and maintain chewy texture
What is the secret to soft chewy cookies?
Using more brown sugar than white tends to result in a moister, softer cookie.
- If you want to increase chewiness, add an extra egg yolk.
- Rolling the cookie dough balls to be taller than wider increases thickness.
- Using melted butter, and little bit more flour increases chewiness as well
- Taking out when they’re very lightly browned is key
I haven’t doubled the recipe yet but I imagine it would be fine to do so.
Should I refrigerate cookies after baking?
Do NOT, no! Unless they contain a cream or custard filling they will go stale much faster and lose quality quickly if stored in the refrigerator. These definitely shouldn’t be put in the cold.
How do I keep fresh baked cookies fresh longer?
- Whether you’re making cookies made from cake mix, or homemade from scratch, storing remains the same.
- Most will stay fresh when stored in an airtight container at room temperature for about three days.
- If you’re not going to consume them before that, it’s best to freeze them.

Peanut Butter Oatmeal Cookie Recipe
- Use mixer to gently blend softened butter, brown sugar, peanut butter, eggs, and vanilla together.
- In a bowl mix together flour, baking soda and salt. Then slowly add this into your wet mixture and blend together.
- Preheat oven to 350 degrees.
- Fold in old fashioned oats, could add 1/2 cup of mini chocolate chips at this time too if you wanted.
- On a non stick baking sheet add dough with space in between. Make them all the same size so they bake evenly.
- Bake at 350 degrees for 9 minutes. Remove when the very middle still looks just a bit wet but edges are lightly browned. Allow to cool on baking sheet so they can continue to cook and stiffen. Do NOT overbake these.
