There are lots of recipes out there and they’re not all the same. Although they’re quick and easy to make, there’s a few things to keep in mind so they turn out perfectly. I’m showing you exactly what you need to do so your chocolate no bake cookies set up properly every time you make them. Once you try them you won’t need any other recipes. This is definitely the best no bake cookie recipe!

What You’ll Need to Make these No-Bake Cookies

For this recipe, it’s best to have everything set up and ready to go before you make the cookies. They are easy, but the process goes fast. 

  • You will need two cookie sheets lined with parchment paper.
  • 3-quart saucepan
  • A whisk
  • Candy or instant read thermometer (more on this in minute!)
  • A cookie scoop

You will also want to have all of your ingredients measured and ready to go. Here’s what you’ll need:

  • Unsalted Butter – slice it for easy melting
  • Granulated Sugar
  • Non-fat Milk – you can use any fat or any non-dairy milk
  • Unsweetened Cocoa Powder – you can use regular or dutch process
  • Peanut Butter – creamy or crunchy
  • Vanilla Extract
  • Salt – omit if you’re using salted butter
  • Quick Cooking Oats

Don’t have quick oats? Make your own by pulsing regular old fashioned oats a few times in a blender or food processor!

How to Make No Bake Cookies

Melt the butter in the saucepan over medium heat. Add the sugar, milk, and cocoa powder and whisk until smooth. Bring the mixture to a boil.

Boiling the mixture is the most important step because you want to cook it long enough to reach a certain temperature and no longer than that.

Secret Tip for Success

You can take the guesswork out of this step by using a candy thermometer or instant read thermometer and boil the mixture until the temperature reaches 230°F.

If you don’t have a thermometer boiling the mixture for 1 minute and 30 seconds is enough, but be sure to set a timer. 

It’s important to be specific with this step because if you don’t boil it long enough your cookies will not set up properly. They won’t harden and will stay soft, which isn’t what we want!

As soon as the time expires (or the thermometer reaches the right temperature) remove the sauce pan from the heat. Quickly stir in the peanut butter, vanilla, salt and oats.

Use the cookie scoop to scoop two tablespoons to make each cookie. Let the cookies sit until they’ve hardened and set. If you want to speed up the process, you can chill them in the refrigerator until they’ve set.

FAQ about these cookies

Why won’t my cookies harden?

If your cookies are too soft and not set up that means you didn’t cook the cookie mixture long enough. In order for the cookies to harden properly the mixture must be boiled until it reaches a temperature of 230°F. This is approximately 1 ½ minutes on medium heat.

How long does it take for no bakes to set up?

It doesn’t take long for the cookies to set up. They will be soft set in 30 minutes, but you can pop them in the refrigerator so the set up faster.

How long do they last?

Keep them in an airtight container and they will last for up to a week at room temperature. Or, store them in the refrigerator and they will last for up to two weeks.

Don’t Forget These Tips for the Best Results!

  • Gather everything you need before you start! The recipe goes fast.
  • Measure out all of the ingredients beforehand to make it super easy.
  • Use a candy thermometer to monitor the heat of the cookie mixture- takes away all the guesswork!
  • Work fast and you’ll be rewarded with perfectly set cookies.
  • Once you’ve made them, be patient! Allow the cookies time to harden and set-up. It doesn’t take long, especially if you put them in fridge.
