Line a large baking sheet with parchment paper and set aside.
Gather and measure out all of your ingredients before starting to make this recipe. The recipe moves fast so you’ll want everything measured out and ready to go before you get started.
In a medium saucepan, heat the sugar, butter and milk over medium-high heat until the mixture comes to a full boil. Stir often.
Once the mixture comes to a full rolling boil (not a simmer), let boil for 1 minute before removing from the heat. Be sure to bring the mixture to a full rolling boil before you set your timer for 1 minute. If you don’t let the mixture stay in a high boiling stage for a full minute, the mixture will not set properly later on when the cookies are chilling.
Remove saucepan from heat and stir in the peanut butter and vanilla extract until the peanut butter is completely melted.
Stir oats into the mixture until all of the oats are evenly coated.
Let the mixture sit and cool slightly for 10 minutes. Letting the mixture cool a bit will help the cookies to hold their shape once you start scooping them. Don’t let the mixture sit for longer than 10 minutes though or it will start to harden in the pot.
Using a 2-tablespoon sized scoop, scoop cookies into round balls and then flatten the tops slightly. Place the cookies onto the prepared baking sheet.
Place the baking sheet of cookies into the fridge to chill for 45 minutes. This gives the cookies a chance to firm up and hold their shape.

Be sure to use certified gluten-free quick oats. Look for any cross contamination warnings on the package to ensure there isn’t cross contamination with wheat.
Alternately you could use gluten-free old-fashioned oats but they are larger so you may want to chop them up a bit.
Do not substitute natural peanut butter as it’s too oily and the cookies won’t set properly.
If the mixture feels too dry to form into cookies, try stirring in an additional tablespoon of melted peanut butter.
For peanut allergies or tree nut allergies, you can substitute the same amount of Wow Butter instead of peanut butter.
If you want to flatten the cookies slightly, do so while the cookies are still warm. If you wait until after they’ve chilled and hardened then you will break the cookies up into crumbles.
To store: Store no bake cookies in an airtight container in the refrigerator for up to 1 week.
