Ingredients
- 1 1/2 cups brown sugar
- 1/2 cup butter
- 1/2 cup milk
- 1 cup smooth peanut butter
- 3 cups old fashioned oats
- 1 teaspoon vanilla
- Pinch of salt
Instructions
- Step 1: Cover a baking sheet with wax paper and set aside.
- Step 2: In a large saucepan over medium heat, stir together the brown sugar, butter, and milk. Bring the mixture to a boil, stirring frequently. Once boiling, maintain a rolling boil for one minute while continuing to stir.
- Step 3: Turn off the heat and stir in the peanut butter until smooth. Then add the vanilla, oats, and a pinch of salt. Mix everything until well combined.
- Step 4: Using a tablespoon or small scoop, portion 2-tablespoon amounts of the cookie mixture onto the wax paper-lined baking sheet. Leave some space between each portion to allow the cookies to set comfortably.
- Step 5: Place the baking sheet in the refrigerator and chill for about an hour, or until the cookies are firm. Enjoy them chilled or bring to room temperature before serving.
Tips & Variations
- Use crunchy peanut butter instead of smooth for added texture.
- For a chocolate twist, add 1/4 cup cocoa powder to the sugar, butter, and milk mixture before boiling.
- Swap old fashioned oats for quick oats if you prefer a softer cookie.
- Press a few chocolate chips or chopped nuts on top before chilling for extra garnish and flavor.
Storage
Store the cookies in an airtight container in the refrigerator for up to one week. To soften chilled cookies, let them sit at room temperature for 10–15 minutes before eating. These no-bake cookies do not freeze well as they can become crumbly upon thawing.

FAQs
Can I use natural peanut butter instead of smooth peanut butter?
Yes, natural peanut butter works fine, but it may alter the texture slightly. Make sure to stir the peanut butter well before mixing, as natural versions often separate.
Do these cookies have to be refrigerated?
Yes, refrigeration helps the cookies firm up and hold their shape since they contain no flour or eggs. Leaving them at room temperature for too long may cause them to become soft and sticky.

- 1 teaspoon vanilla extract
Dry Ingredients
- 1 1/2 cups brown sugar
- 3 cups old fashioned oats

- Chill Cookies: Place the baking sheet in the refrigerator for at least one hour or until the cookies are firm and set. Once chilled, enjoy them cold or allow them to reach room temperature before serving.
