If you are following me on Instagram, you saw over the weekend that my family did our annual trip to the corn maze. We had such a good time!

I’m officially in the sweet spot of parenting. They are out of diapers, but still want to spend time with me. I’m going to just sit back and savor that for a moment while giving you this sweet spot: Peanut Butter No Bake Cookies.

How to Make Peanut Butter NO Bake Cookies

These cookies are so simple to make.

  1. Start by melting butter, sugar, and milk together in a large sauce pan.
  2. Stir consistently and bring the mixture to a boil.
  3. Let it boil for one minute before removing it from the heat.
  4. Remove from the heat and add the oats, peanut butter, and vanilla.

Tips for Peanut Butter No Bakes

  • You are looking for a raging boil. We aren’t talking a few bubbles. You want to see a really foamy and frothy boil before moving on to your next step.
  • Stir continuously. This isn’t a recipe to walk away from.
  • Work quickly. Once the mixture has boiled and you are adding the other ingredients, move fast.

Old Fashioned Oats or Quick Cooking Oats

Peanut Butter No Bake Cookies work out best with old fashioned oats. Quick cooking oats are broken down into small pieces and so your cookies aren’t going to have the same look or texture with them.

That said, if all you have is quick cooking oats, you can still make these and you will enjoy them.

Freezing Peanut Butter No Bake Cookies

No bake peanut butter oatmeal cookies are perfect for freezing!

  1. Line a baking sheet with wax paper (or just use the sheet you used while making them).
  2. Line the tray with the cookies (they can touch each other).
  3. Put in the freezer for a half hour to an hour. Then take them out and transfer them to a freezer safe container, stacking them.
  4. Return to the freezer.

When you are ready to eat them, just leave them out until they thaw. Overnight usually does the trick.

Are Peanut Butter No Bake Cookies Gluten Free

In theory, yes. But it really depends on what types of oats you are using.

Technically oats are gluten free, but a lot of companies who produce them also produce other grains and therefore can’t guarantee no gluten is in their oats.

If you are making these for someone who cannot have gluten, make sure the packaging on your old fashioned oats guarantees they are gluten free.

    5 stars
    These were the best no bakes I have ever made I think the secret is using old fashioned oatmeal they turned out perfect made them the next day with quick kind and they weren’t that good dry and dull so thanks for the great recipe and hints

    • Lisa Longley says

      I’m so happy that you liked them, Sandy!

  2. Mary says

    I wondered if you could use Splenda instead of sugar? I’m a diabetic, but these sound so good!

    • Lisa Longley says

      Hi Mary! I don’t have a lot of experience making desserts with Splenda. If you give this one a try, let me know how it goes.

  3. Dorothy Rider says

    These are good with chocolate drizzled over them.

    • Lisa Longley says

      That sounds like a great addition!

  4. E evert says

    Almost everything came out fine. Except it’s not firming (soft). I put in fridge and it’s somewhat firmer.
    Don’t know what I did wrong. ?

    • Lisa Longley says

      I’m so sorry, without me being there with you, its hard to know what went wrong. This recipe always firms up very quickly for me. With this particular recipe, my only suggestion (an annoying one for sure) is to to double check that you measured everything correctly.

  5. Audrey says

    Hello…my husband loves peanut butter so I want to make these for him. Does it matter what kind of milk? Whole, 1%, almond? Thanks ~A

    • Lisa Longley says

      I used skim. Any fat level will work in this recipe.
