No-Bake Chocolate Oatmeal Cookies are an old-timey favorite and one of the easiest and most delicious cookies you’ll ever make. I think pretty much everyone has had these cookies at one time or another and pretty much everyone loves them.
No oven needed for these cookies which have the most amazing texture and you likely have all the ingredients on hand. You’ll need butter, unsweetened cocoa powder, sugar, milk, quick-cooking oats, peanut butter, and vanilla extract.
The butter, cocoa powder, sugar, and milk are placed in a saucepan and brought to a boil. Let the mixture boil for 90 seconds. Set a timer and keep track becasue the cookies might not set up right if you boil the mixture too long or not long enough.
Then remove the mixture from the heat and stir in the remaining ingredients. So simple!
In less than 10 minutes you can have the ingredients measured, the batter mixed together and shaped into cookies. These No-Bake Chocolate Oatmeal Cookies do need a little while to set, but you won’t have to wait long. They should only take about 30 minutes to set up. If they are still too wet at this point, try sticking them in the fridge.
This recipe makes a pretty large batch of cookies- about 24 cookies. They are dense and filling cookies so they will go a long way. That being said, it is hard to not go back for another. 🙂

Tastes like my childhood! My mom always popped them into the fridge for a really amazing treat. Try them on the counter but also can put some in the fridge! It’ll blow your mind.
Amazing recipe thank you for sharing! My kids adored these, and it brought me closer to my Mom and memories. This was the cookie my mom made every weekend in the summer.

So easy and yummy just like Grandma’s they turn out perfect every time 👍
I have made these for years and they have always turned out good a little over a year ago I moved and now use a gas stove and for some reason the cookies won’t set I’ve used a gas stove in the past and they turned out what am I doing wrong
Gas is hotter.
Amazing if you follow the directions they come out PERFECT! I make them every yr and threw out the yr they come out perfect every time! Make sure you do the 90 sec as soon as they start to boil turn it down don’t forget or you will bring it! Don’t leave the stove when making these it’s easy to walk away an they boil an you ruined them that fast! Timing is everything!!
Could not save these…followed the recipe exactly, wound up with mounds of granulated chocolate and oats that didn’t behave like any no-bake I’ve ever made, and I’ve been cooking and baking for over 4 decades. Darn. Hoped they’d work but they didnt.
Did you let boil for 90 secs? Did you put in the correct measurements? I put everything in a sausepan at once then when it started to boil that’s when i started my timer. Mine turned out correctly.
Hi. Sorry but what helps me is I put the cookies in the freezer for a short time after I form them and they harden and stay together well. Years ago I didn’t need to do that but today I do or they won’t set up like they should.
I just made these, even used generic ingredients and they are perfect! You have to do the 90 second boil for sure
Delicious! Perfect blend of sweet chocolate, and salty peanut butter. Bonus: Super simple and quick!
Just did this and followed the recommendations in comments to boil for 60 seconds the. Add the other ingredients. Turned out great!
I read the comments before I tried this. I didn’t boil too long but I dont think I boiled long enough. My question is does it have to be a rolling boil to start the 60-90 sec clock?
Part 2 of my question now that I have a bunch of sticky gooey mounds what can I do to make them into something? Can bake? Melt again and something?
When the actual visible boil starts thats when the 90 sec clock starts. Question 2: nope. Toss or eat as is.
Ice cream topping!
I just tried these and they turned out perfect ! Just good 60 seconds instead of 90 cooking ! They were the pretty, tasty and best ones I have ever done.
Can I use old fashioned oats instead of quick-cooking oats?
No, they will not cook fast enough.
Darn, I just tried them with old fashioned. We shall see. If they flop I know my son will still eat them!
These were a childhoid favorite of mine and now I make them for my grandchildren
I always use old fashion oats. No problems. actually….they’d take longer to cook. Not less time but none of the oats ever cook anyway. Only problem I know of is I eat too many of these delicious cookies.
I noticed that other recipes for no-bake cookies (which did not have peanut butter)used same amount of butter and sugar and cocoa so I added an extra 1/2 cup of oatmeal. They came out fine and using a heaping TBSP measure made 40 cookies of a size I like.
I made this recipe to the t twice and both times my cookies never set up. What am I doing wrong? Ugh these are supposed to be for a work party tomorrow and bane sale Thursday and they are ruined. How to fix? The first time I tried making recipe a few months ago and when they didn’t set up I put in frig and that did not help. They were super gooey. The kids at church loved them but I did not
What kind of butter did you use? I have found that you have to use real butter or pure margarine. A butter or margarine spread will not work. You cannot use Blue Bonnet. I always use either real butter or Land o Lakes Margarine sticks. Hope this helps.
I just made a batch that came out perfect!! I made them exactly as the recipe directed using unsalted real butter (Great Value brand).
I think you need to cook the mixture the stovetop a little more.
Can I use brown sugar instead of regular sugar
I made them this afternoon and a mistake was made in my batch. I corrected my sugar and cocoa powder. Boiling for 60 seconds made the grade. B SWEET ESSENTIAL DESSERTS.
Anyone ever tried adding coconut? I switched the peanut butter for shredded coconut, packed in the measuring cup and 2 T coconut oil. They were awesome.
Other than cutting the ingredients in half to make a small batch, I followed this recipe as written and the cookies came out perfect! I will definitely be making these again.
What you sre doing by bringing the mixture to a low boil is tempering the chocolate. Then it will set. Try lightly buttering a sheet pan & pouring the mixture in it. Smooth it out & let set. Cut into small bars. They are thick, rich, delicious & shiny!! I do put less oatmeal & I use store brand oatmeal-broken into pieces. Or crush yours. I add toffee or pecans chopped up.
