Ingredients

This section includes ingredient notes and substitution options. Get all measurements, ingredients, and instructions in the printable recipe card at the end of this post.

To make no bake chocolate peanut butter oatmeal cookies you will need:

  • sugar
  • butter— real butter is a must so save the margarine for another day.
  • milk— whole milk is best, but any milk will work.
  • unsweetened cocoa powder
  • peanut butter— Use creamy peanut butter rather than crunchy peanut butter to get the proper chewy texture. Natural peanut butter can be used as well, just stir it up well before using. 
  • vanilla— Use pure vanilla extract for the best flavor. 
  • quick cooking oats

Substitutions and variations

Unsalted butter: Only have unsalted butter? No worries, just add a pinch of salt to the recipe.

Old-fashioned oats: While quick oats result in perfectly tender cookies, you can also use old-fashioned rolled oats. Your cookies will just be a bit chewier and less tender.

Nut-free: Use sunflower seed butter instead of peanut butter for a nut-free no bake cookie.

Tips for the Best No Bake Cookies

Prep ahead – Measure out your ingredients before you begin making the no bake treats. This will allow you to work quickly to add the ingredients when you remove the mixture from the stove.

Use a timer – When boiling be sure to set a timer for 1 minute. Under-cooking can cause the no-bakes to not set up properly. Over-cooking can make your no bake chocolate oatmeal cookies dry and crumbly.

Wait for a full boil – Don’t start your 60-second timer until the mixture has reached a full, rolling boil. This means that it is bubbling up in the middle of the pot, not just around the edges.

Work quickly – Once you remove the pot from the stove work quickly to stir in the rest of the ingredients and get your cookies scooped out while they are still hot. If you wait too long it will start setting before you are finished!

No Bake Cookie Recipe FAQ

Why did my no bake cookies not set?

The most common cause of no-bake cookies not setting is that they didn’t boil long enough. Be sure to wait until the mixture has reached a rolling boil then boil for a 60 seconds. Another cause could be the weather. Yes, the weather! Very humid or rainy weather can mess with the setting process. If you find this is an issue, I suggest placing the cookies in the fridge to help them harden.

Do no bake cookies have to be refrigerated?

No, the yummy cookies do not need to be refrigerated, although you can refrigerate them if you like. No bake cookies can be stored in an airtight container at room temperature for up to one week.

Can no-bake cookies be frozen?

Yes! Freeze set and cooled cookies in an airtight container for up to 3 months. Remove form the freezer and thaw to room temperature before serving.

Why are my chocolate no bake cookies dry and crumbly?

If your no bake oatmeal cookies are dry and crumbly they were probably overcooked.

  1. I have found that one minute boiling is not enough. Cookies do not set up, and are sometimes actually sticky like carmel. I boil mine 2 to 3 minutes. if you stir during boiling, your finished product can become grainy. The base of these cookies is actually quick fudge, and will react like fudge. Undercook- it won’t set up, overcook or stir during boiling, it gets grainy.

  2. I love the flavor of this recipe! But I find that one minute at a full rolling boil does not set them up for me. I do approximately 2-1/2 minutes. I have used old fashioned oats and they work just fine too. Delicious cookie!

    1. That is a good question. I haven’t tried making these into bars but I think it should work. If you do decide to give it a try please let me know how they come out.

        They do great as a bar cookie. I did it several times. Just press them on in the pan . Let the cool and cut. I have found using a spatula to get the out is best!

      2. I’ve been making these as bars for at least 2 decades! I simply cover a 10×15″ pan with foil, pour the mixture on, and gently smooth it out. You have to be careful not to press down on it too much, or it turns into a replacement for cement 😕

    1. 5 stars
      I just made these with whipping cream instead of milk and I added a cup of chocolate chips. These taste phenomenal! Thank you for this amazing recipe!

  3. 5 stars
    I use 1 cup granulated sugar and 1 cup brown sugar and 2 teaspoons of vanilla and my recipe makes 3 dozen using the scoop. Great recipe!

  4. Looks delicious- I’m going to make it and try using Lakanta monk fruit sugar- I am diabetic and all other ingredients are ok. I think it will work.

  5. I love the cookies, but I can never get them to work. They never set up and their one big crumbly mess. What I’m I doing wrong? It makes me so mad. A lot of waste
