Peanut Butter No Bake Cookie Recipe Ingredients
Ingredients You’ll Need
- 3 cups of quick-cooking oats
- ¼ teaspoon of salt
- ½ cup of butter
- 2 cups of sugar
- ½ cup of milk
- 1 cup of peanut butter
- 2 teaspoons of vanilla extract
Substitutions And Additions
Peanut/Nut Butter: This recipe works best with creamy peanut butter. Avoid natural peanut butter – it separates easily and can lead to oily, soft cookies that won’t set well. You can swap with almond butter, if you’re looking to go nut-free.
Butter: Use unsalted, or skip added salt if using salted.
Oats: Quick oats work best. in a pinch. Old-fashioned oats aren’t ideal—they don’t soften as well and affect the texture. If that’s all you have, pulse them briefly in a food processor to break them down.
Mix-Ins: Add marshmallows, M&M’s, Reese’s, a Hershey’s Kiss, or a chocolate drizzle.

⏱️ Boil for one minute – Start timing once it hits a full, rolling boil. Undercooking = cookies won’t set or stay sticky. Overcooking = dry or crumbly. This step makes or breaks the texture.
🥣 Mix evenly – Stir the peanut butter mixture and oats together thoroughly but gently to ensure even texture in every bite.

🥄 Work fast – Once the oats go in, the mixture starts setting quickly. Scoop immediately for nicely shaped cookies.
🧻 Line your tray – Use wax or parchment paper to prevent sticking and make cleanup a breeze.

❄️ Let them cool completely – Cookies set as they cool. If they’re still sticky after cooling, give them more time or refrigerate to help them firm up.
Storing No Bake Cookies With Peanut Butter & Oats
Once the cookies have cooled and set, transfer them to an airtight container. It’s very important you let them cool on the counter before putting them in the fridge or they will become gooey.
They’ll keep at room temperature for up to four days, or in the fridge for up to a week if you prefer them firmer. Avoid stacking them while still soft—use parchment between layers if needed.
Freezing isn’t ideal—the texture can turn crumbly after thawing, so they’re best enjoyed fresh.
