For Peanut Butter No-Bake Cookies
- Unsalted Butter – Adds richness and helps bind the cookie mixture. Cut into small pieces so it melts evenly.
- Granulated Sugar – Sweetens the cookies and helps create that soft, chewy texture.
- Nonfat Milk – Thins the mixture just enough while keeping it light.
- Creamy Peanut Butter – The star of the show! Use regular (not natural) peanut butter for the best texture.
- Vanilla Extract – Adds warmth and depth to the flavor.
- Salt – Just a touch to balance the sweetness and bring out the peanut butter.
- Quick-Cooking Oats – These oats give the cookies structure and that classic chewy bite.
Peanut Butter No-Bake Cookies
Notes
Ingredients:
- ½ cup (113g) unsalted butter, diced
- 1 ¾ cups (350g) granulated sugar
- ½ cup (118ml) nonfat milk
- ½ cup (133g) creamy peanut butter
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- 3 cups (243g) quick-cooking oats
Instructions:
- Prep Ahead:
Measure out all your ingredients before starting. This recipe comes together quickly, so you’ll want everything ready to go. - Prepare Baking Sheets:
Line two cookie sheets with parchment paper. - Cook the Base Mixture:
In a 3-quart saucepan, melt the butter over medium heat. Stir in the sugar and milk, and whisk until the mixture is smooth. Bring it to a boil and cook for about 1 ½ minutes, stirring occasionally.- Important: The mixture needs to reach 230°F to set properly. Use a candy thermometer or instant-read thermometer if possible. If you don’t have one, 1 ½ minutes at a steady boil on medium heat should do the trick.
- Mix the Cookie Dough:
Remove the pan from the heat. Stir in the peanut butter, salt, vanilla extract, and oats. Mix until fully combined. - Scoop and Shape:
Use a cookie scoop or spoon to drop 2-tablespoon-sized portions onto the lined baking sheets. - Let Set:
Let the cookies sit at room temperature until firm, or place them in the fridge to set more quickly.
- You can use creamy or crunchy peanut butter—just avoid natural kinds with oil separation.
- Chopped nuts or mini M&Ms make great mix-ins if you want to switch things up.
- Using a thermometer helps guarantee perfect texture every time.

1. Why didn’t my cookies set properly and remain gooey?
This usually happens when the sugar mixture doesn’t boil long enough. Be sure to bring the sugar, butter, and milk to a full rolling boil and maintain it for about 1 to 1.5 minutes. For best accuracy, use a candy thermometer and aim for 230°F—this helps ensure the cookies firm up as they cool.
2. Can I use old-fashioned rolled oats instead of quick-cooking oats?
Yes, you can! Just note that the texture will be a bit chewier with old-fashioned oats. If you prefer a smoother, more uniform cookie, stick with quick-cooking oats.
3. Is it possible to reduce the sugar content without affecting the cookies’ texture?
Reducing the sugar can impact both the texture and the ability of the cookies to set properly. For best results, it’s recommended to follow the original sugar measurements.
4. Can I substitute natural peanut butter for regular peanut butter in this recipe?
You can, but be aware that natural peanut butter’s oil separation can alter the texture. If using it, make sure it’s thoroughly stirred and well combined. For the most reliable outcome, regular creamy peanut butter is preferred.
5. How should I store these cookies, and how long will they remain fresh?
Store the cookies in an airtight container at room temperature for up to 1 week. For longer storage, freeze them in a single layer, then transfer to a freezer-safe container or bag—they’ll keep for up to 3 months.
