Peanut Butter No Bake Cookie Recipe
These no bake peanut butter oatmeal cookies are so simple and come together in just about 10 minutes. They’re full of gooey marshmallows, oats, and lots of peanut butter. I like to make them on Sunday evening before we start a movie or even before school if I’m running low on groceries and the kids need a treat for their lunches.

There are a few things that will help your no bake endeavors come off without a hitch. I like to make mine in a nonstick pan because it helps keep your cookies from burning and also makes cleanup that much easier.
If you’re in a pinch and don’t have wax or parchment paper, a cookie sheet sprayed with nonstick spray works great, too.
Key Ingredients
- Butter – you can use salted or unsalted for this recipe. If you used salted, you might want to eliminate the pinch of salt.
- Milk – this thins everything down just enough that they can be mixed together. I recommend using whole milk but 2% will work.
- Sugar – you will need white granulated sugar for this recipe. Cooking the sugar is what helps the cookies bind and hold their shape.
- Peanut Butter – you can use creamy or chunky peanut butter. Just make sure it is not the type that separates. I recommend using a brand like Jif or Skippy.
- Mini Marshmallows – I like to use mini marshmallows because they melt more easily. You could also chop up regular sized marshmallows.
- Old Fashioned Rolled Oats – in order for these cookies to have the right texture, make sure you use old fashioned rolled oats instead of instant oats or steel cut oats.
How to Make No Bake Peanut Butter Cookies
- Cook the butter, milk, and sugar. In a non-stick pan, melt the butter. Add the milk and sugar and bring to a boil. Boil for 1 minute, then remove from the heat.
- Add the peanut butter and marshmallows. Stir in the peanut butter and mini marshmallows. Continue to stir until the marshmallows are melted.
- Add the oats and salt. Once the marshmallows are completely melted, stir in the oats and salt. Mix well.
- Portion the no bakes. Drop by the spoonful onto a baking sheet covered with parchment paper.
- Cool then serve. Allow the cookies to cool at room temperature. Serve immediately or store in an airtight container for 3 days at room temperature or up to 1 week in the fridge. Enjoy!
Recipe Variations To Try
- Add 1/2 cup of coconut in place of 1/2 cup of oats
- Add 1/4 cup cocoa powder to make them chocolate peanut butter
- Switch out the peanut butter for almond butter or Nutella
- Switch out the vanilla extract for almond extract or coconut extract
- Add more marshmallows and don’t let them melt all the way so that you have marshmallow bits
Frequently Asked Questions
If your Peanut Butter No Bakes are turning out gooey, chances are you didn’t boil the sugar mixture for a full minute. The sugar needs to reach the soft ball stage of cooking, which means that the correct amount of moisture will have evaporated.
You can use either creamy or chunky peanut butter for this no bake recipe, just make sure you use a brand like Jif or Skippy rather than a more natural peanut butter that separates. This will help keep the texture good and help them stick together well.
Storing No Bake Cookies
- Room Temperature: store in an airtight container in a cool, dry place for up to 3 days at room temperature.
