Notes on the Ingredients You’ll Need

Believe it or not, less than ten simple ingredients are all you need to make a drool-worthy peanut butter oatmeal cookies recipe!  

• Old-Fashioned Oats – Make sure to use old-fashioned oats, not quick oats or steel-cut oats. The taste and texture won’t be the same! Old-fashioned oats are larger and chewier than other varieties. 
• All-Purpose Flour – This adds extra structure to the cookies, helping them hold their shape and enhancing the chewy texture. 
• Baking Soda – Make sure it’s fresh!
• Salt – A little goes a long way to enhance the flavor of the rest of the ingredients 
• Cinnamon – Not found in every peanut butter oatmeal cookie recipe, this adds extra warmth and depth, enhancing the sweetness. 
• Butter – Unsalted butter is best. Allow it to come to room temperature for easy mixing. 
• Peanut Butter – We recommend using creamy peanut butter, but chunky will work, too. Just don’t use natural peanut butter as it will separate and cause your cookies to become oily. JIF, Skippy, or a similar brand are best. 
• Sugar – A combination of granulated sugar and brown sugar is used to sweeten the cookie dough while keeping it soft and moist. 
• Eggs – We use a large egg and an extra egg yolk to provide structure to the dough along with a super rich, gooey taste and texture. 
• Vanilla Extract – Use high-quality pure vanilla extract. 

How to Make Oatmeal Peanut Butter Cookies that Are Soft and Chewy

With minimal prep time and a cook time of less than 15 minutes, this might be the easiest, most delicious cookie recipe you’ll ever make! 

1. Prepare. Before you begin, preheat your oven, and line two large baking sheets with Silpat baking mats or parchment paper. 
2. Whisk the dry ingredients. In a medium bowl, whisk together the oats, flour, baking soda, salt, and cinnamon. 
3. Beat the wet ingredients. Using a stand mixer or a hand mixer and a large bowl, beat the butter, peanut butter, and both sugars together on medium speed until smooth and creamy. Add the egg, egg yolk, and vanilla, and mix again until well combined. 
4. Combine the wet and dry ingredients. With the mixer on low, slowly add the dry ingredients to the bowl of wet ingredients, and mix just until combined. 
5. Bake. Use a cookie scoop to portion the dough, and arrange them on the prepared baking sheets, leaving space in between each cookie. Transfer the sheets to the oven, and bake just until the cookies are lightly browned around the edges. 
6. Cool. Allow the oatmeal peanut butter cookies to cool on the baking sheets for a few minutes before transferring them to a cooling rack to cool completely.

A Few Baking Tips

Chill the Dough. If you want extra thick and chewy cookies, simply chill the dough before baking! Simply assemble the dough, and cover the bowl with plastic wrap.

It can be stored in the fridge for up to 48 hours before baking. Just be sure to add a few extra minutes of baking time as needed! 

Avoid Overbaking. The key to creating soft and chewy oatmeal peanut butter cookies it to slightly underbake them. You’ll want to remove them from the oven as soon as the edges begin to turn golden brown and the center is still soft. They’ll continue to bake and set as they cool! 

How to Store

Once cooled, leftover cookies can be transferred to an airtight container or sealable bag and stored at room temperature for up to one week. 

How to Freeze

Baked cookies can be frozen for up to three months. To prevent them from clumping together, place a piece of parchment paper between each cookie! 

Unbaked cookie dough can be frozen for up to three months. Assemble the dough as the recipe instructions state, arranging the balls on baking sheets. Then, place them in the freezer until solid, and transfer them to a sealable bag. 

When you’re ready to eat, simply bake from frozen, adding a few minutes of baking time as needed. No need to thaw first!
