Helpful Supplies For This Recipe
Below are some kitchen tools that I find helpful for making peanut butter oatmeal cookies:

How do I make Peanut Butter Oatmeal Cookies?
The process of making these peanut butter oatmeal cookies is quite simple. You will create the cookie dough and let it chill. Bake the cookies. Let them cool completely and you’re ready to enjoy! Detailed instructions are explained below:
Making the Dough
- Start by beating your butter and sugars together in your stand mixer or in a large mixing bowl with a hand mixer.
- Next add in your eggs one at a time. Add in vanilla.
- Lastly, mix in your peanut butter until well incorporated.
- In a separate mixing bowl, you will whisk together your dry ingredients: flour, oats, baking soda, baking powder, salt, and butterscotch chips.
- Next you will add your dry ingredients to your wet ingredients just until combined. You don’t want to overmix as this will result in a tougher cookie.
- Place the dough in the refrigerator for 20-30 minutes before creating your cookie dough balls. It will be a little sticky at first so letting it chill slightly will make it easier to manipulate into your dough balls later.


Preparing the Cookie Dough Balls
- Once your dough is chilled, using a large cookie scoop, portion your cookies out onto a cookie sheet lined with wax paper. This will yield about 32 large cookies.
- After forming your cookie dough balls, you can either begin baking or you can cover the tray with plastic wrap and continue to chill for up to 48 hours before baking. I like to let mine chill for another 1-2 hours or longer before baking.

Baking the Cookies
- Preheat the oven to 350 degrees.
- On a large cookie sheet lined with parchment paper, place 6-8 cookie dough balls spaced about 3″ apart.
- Side note: Keep the cookie dough balls that are not currently in the oven in the fridge until right before you’re ready to use. You want to keep the dough chilled for best results!
- Bake for 12-14 mins. Cook time will vary by oven. The perfectly soft baked cookie will come out with the edges just starting to crisp and a middle that still looks soft.
- Let them cool on the cookie sheet for 15 minutes before moving to the cooling racks to finish cooling. The’ll finish baking while resting on the sheet.
- Enjoy!!

Notes
Tips for making The Best Peanut Butter Oatmeal Cookies
- Chill the dough before baking. Chilling cookies allows the flavor to develop well, it makes the dough easier to work with and it keeps your cookies from spreading too much while baking.
- Bake quicker: Prepping your dough balls all at once makes the baking process go by quicker. I also like to get two trays rotating when making batches of cookies. While one is baking, the others are cooling on the tray until it’s time to move them to the cooling rack. Once the ones that are cooked are cooled, it’s time to get another batch in and I can use that cooled baking tray.
- Freeze for later. This makes a large batch of cookie, which is great when you are serving a crowd, but not so much when you want to feed your family a little treat and are watching your waistline! The good news is that these freeze beautifully. I encourage you to freeze whatever you aren’t ready to eat yet and just pull them out the next time you want a quick dessert. They thaw quickly or can be baked from frozen with adding 2-3 minutes of additional bake time.
- KitchenAid Mixer – my mixer has been in use for decades and still going strong!
- Adjustable Measuring Cup – this is perfect for the honey! I use this anytime I need to measure something of similar texture of honey, such as peanut butter, sour cream, etc!
- Stackable Cooling Racks– A life saver for a small kitchen with minimal counter space!
- Large cookie scoop – large cookies are my go-to and this scoop has worked really well
- Glass Mixing Bowls – this set comes with matching lids, which is super helpful
- Large cookie tray – work great for baking larger cookies
