One of my most popular recipes, especially around the holidays, is my Chocolate No Bake Cookies. They are truly delicious. Though every time I share them on social media, I get asked the same question: How do I make these without coconut? Fair enough; I know not everyone loves coconut as much as I do.

These amazing no bake cookies are everything you like about the original recipe without the coconut. Just a quick swap of more oats for coconut does the trick, and you get amazing melt-in-your-mouth chocolate cookies.

How to Make Chocolate No Bake Oatmeal Cookies

Combine the sugar, milk, butter, and cocoa powder.

Start stirring right away so the sugar doesn’t burn.

Boil for exactly one minute. 

This is a very important step. The liquid should be at a roaring boil for one minute. Use a timer to make sure it has been a full 60 seconds, and do not start the timer until you see a full roaring boil.

Stir in the rest of the ingredients.

Remove the pan from the heat and stir in the oats, peanut butter, and vanilla, moving somewhat quickly.

Form into cookies.

Drop the mixture by spoonfuls onto wax paper or parchment paper and let cool. I like to use a cookie scoop I this step for consistent sized cookies and because it makes this step so fast.

Why did my no bake cookies not set?

The key to getting the cookies to set is bringing your butter and sugar mixture to a full raging boil for a full minute, watching closely. If your kitchen is overly warm or humid, place the cookies in the refrigerator to set.

Tips For No Bake Cookies

  • Look for a rolling boil. You will want large bubbles in the middle of the pan with a foamy and frothy boil before moving to the next step. Skipping this step or not boiling long enough will result in cookies that don’t set up.
  • Stir continuously. Your ingredients will burn if you walk away from the pan.
  • Work quickly. This recipe moves quickly. Once the mixture has boiled and you are adding the other ingredients, move fast. This will allow you to scoop all your cookies before they start to set.
  • Use old-fashioned oats. No Bake Chocolate Oatmeal Cookies work best with old-fashioned oats. Quick oats are more fine so have a different texture and may not set up as well. If all you have on hand is quick-cooking oats, you can still make these and you will enjoy them.
  • Use real butter, not margarine. The type of butter also matters. I recommend that you don’t use Kirkland butter as it is notorious for not working in this recipe.

Storing and Freezing

Store your No Bake Chocolate Oatmeal Cookies in an airtight container at room temperature for up to two weeks.

These No Bake Cookies are great to freeze. Once cooled, place them in a freezer bag or freezer-safe container and freeze for up to three months. Enjoy frozen or let thaw on the counter or in the refrigerator.
