These chewy and delicious Peanut Butter No Bake Cookies are made with creamy peanut butter, vanilla, brown sugar, butter and rolled oats. Ready in less than 20 minutes, they couldn't be any easier to make - just mix, set, and enjoy!
Ingredient notes and substitutions
- Butter - to make these peanut butter no bake cookies, I used unsalted butter. If you only have salted butter on hand, you can use that and omit the added salt in the recipe. (more delicious dessert recipes)
- Light Brown Sugar and Granular White Sugar- Using a combination of the 2 adds a depth of flavor to the cookies. The brown sugar imparts a delicious molasses flavor.
- Vanilla Extract - The vanilla extract helps pull all the flavors together and adds a hint of vanilla flavor. These are also great with caramel extract.
- Peanut Butter - You want to make sure you are using a thick peanut butter. The consistency will not be the same with an oilier natural variety.
- Old-Fashioned Oats - For this recipe, I used old-fashioned rolled oats. You can also use quick oats.
Step by Step Instructions
STEP 1: Melt the butter in a large saucepan over medium heat. Stir in the brown sugar and granulated sugar.
STEP 2: Continue stirring for 3 to 4 minutes, or until the sugar starts to bubble. Stir in the peanut butter, vanilla extract and salt.
STEP 3: Continue mixing until smooth and all ingredients are well incorporated.
STEP 4: Using a rubber spatula, fold in the oats. Mix until all of the oats are evenly coated.
STEP 5: Line a large baking sheet with parchment paper. Use a 2 inch cookie scoop to scoop 16 cookies onto the baking sheet. Transfer the baking sheet to the fridge for 30 minutes to allow the cookies to set.
Recipe Tips and Variations
- Storage: Store in an airtight container for up to 5 days. (These are my favorite storage and meal prep containers)
- Make them low carb: You can make these peanut butter no bake cookies low carb by using a reduced sugar peanut butter, swapping the sugars out for a low carb sweetener like brown sugar erythritol or monk fruit, and by swapping the oats out for unsweetened coconut flakes, or even chopped mixed nuts.

- Make them sugar free: To make a sugar free version of these no bake cookies, simply use a no-sugar added peanut butter and replace the brown sugar and white sugar with your favorite natural sweetener substitute. (More sugar free cookie recipes)
- Add cocoa powder: for a more traditional chocolate no bake cookie, add ¼ cup of unsweetened cocoa powder.
- Add chocolate chips: For some added crunch and some chocolatey goodness, add ½ cup of chocolate chips to the mix. (Try these Marshmallow Chocolate Chip Cookies)
- Add Butterscotch chips: Take things up a notch and add some butterscotch chips into the mix. You can melt them in with the peanut butter, or you can mix them in when you add the oats. (I use this brand of butterscotch chips)
- Add crunchy chow mein noodles: For a no-bake haystack cookie, swap the oats out for crunch chow mein noodles. (I use this brand)
