Yes, you can use rolled oats instead of quick oats in no-bake cookies. Just use the same amount of rolled oats as the recipe calls for quick oats.
Ingredients for Old Fashioned Oat No Bake Cookies
To make old fashioned no bake cookies, you will need:
- White Sugar – I use granulated sugar for a rich, flavorful taste.
- Whole Milk – For the best results, it is best to use whole milk for a richer fudge mixture, but you can use any milk.
- Butter – Use real butter (salted or unsalted) for best results.
- Cocoa – Adds delicious chocolate flavor; use natural cocoa, cacao, or Dutch cocoa powder.
- Peanut Butter – Use creamy for a smooth texture or chunky for extra crunch.
- Old Fashioned Oats – I prefer their chewier texture over quick oats.
- Vanilla – Enhances the cookies’ flavor with just a small amount.
How to Make No Bake Oatmeal Cookies with Old Fashioned Oats
Here is how to make the best no bake cookies recipe with old fashioned oats.
- Prepare Baking Sheets – Line two large baking sheets with parchment paper and set them aside.
- Mix the Ingredients – Place a medium saucepan or Dutch oven over medium heat. Add the butter and let it completely melt. Then, add the granulated sugar, milk, and cocoa powder. Stir the mixture to ensure everything is thoroughly combined.
- Boil the Mixture – After mixing, bring the chocolate mixture to a full rolling boil. Set a timer for one minute and let it boil.
Tip: Boiling too long will result in dry no bake cookies, and not boiling enough will prevent them from being set properly. The boil time is very important.
- Add Remaining Ingredients – Remove the pan from the stove after the mixture boils for one minute. Stir in the creamy peanut butter, old-fashioned rolled oats, and vanilla. Keep stirring until the ingredients are blended and the oats are evenly coated.
- Drop Cookies onto Baking Sheet – Use a cookie scoop or large spoon to drop 1 ½-2 tablespoons of the no-bake cookie mixture onto the parchment-lined baking sheet.
- Let the Cookies Set – The cookies will have a soft texture but as they set, they will gradually become firmer as they cool. Allow them to set for 20-30 minutes.
- Gather Ingredients – To make this process go quickly and smoothly, gather and measure all the ingredients before making the cookies.
- Mix Quickly – After removing the mixture from the stove, add the remaining ingredients and mix. Scoop out cookie-size portions quickly to prevent the cookie dough from cooling and hardening in the pan.
- Let the Cookies Set – Allow the cookies to cool for at least 20-30 minutes so they have time to set fully.
This no bake cookie recipe with old fashioned oats is the perfect treat for anyone craving a delicious cookie. Whether an after-school snack or a quick and satisfying dessert.

Printable Recipe Card
- 1 3/4 cup white sugar
- 1/2 cup whole milk
- 1/2 cup butter, cut into slices
- 4 tbsp cocoa powder
- 1/2 cup peanut butter
- 3 cups old fashioned oats
- 1 tsp vanilla
Begin by lining two large baking sheets with parchment paper and putting them aside.
Add the butter to a large saucepan or enameled Dutch oven and melt over medium heat. Once melted, add the granulated sugar, milk, and cocoa powder. Bring to a rolling boil and boil for one minute.
Once the mixture reaches a rolling boil, set a timer for 60 seconds. The rolling boil should be evident – the top should be entirely covered with bubbles.
Boiling too long will result in dry no bake cookies, and not boiling enough will prevent them from setting properly. Thus, timing is of the utmost importance.
Once the timer has gone off, take the pan off the stove and stir in the peanut butter, old-fashioned oats, and vanilla. Mix until all the ingredients are blended and the oats are evenly coated.
Drop no-bake cookie mixture by approximately 1 ½-2 tablespoon spoonfuls onto the prepared parchment-lined cookie sheet using a cookie scoop or spoon.
The cookies will have a soft texture but gradually become firmer as they cool. The cookies usually take 20 to 30 minutes to be fully set.
- Before beginning these cookies, gather and measure all the ingredients. Doing this in advance will make the process go quickly and smoothly.
- Once you take the mixture off the stove, quickly mix the remaining ingredients. Then, scoop out the cookie-size portions immediately; if you wait too long, the cookie dough will begin to cool and harden in the pan.
- Allow the cookies to cool for 20-30 minutes to set fully.
