Description
These classic Peanut Butter No-Bake Cookies are chewy, rich, and packed with the irresistible flavor of peanut butter and oats. They come together in minutes — no oven required — making them the perfect quick treat or lunchbox snack.
Ingredients
- 1/2 cup (1 stick) unsalted butter
- 1 3/4 cups granulated sugar
- 1/2 cup milk
- 1 teaspoon vanilla extract
- 3/4 cup creamy peanut butter
- 3 cups quick-cooking oats
- Pinch of salt (optional)
Instructions
- Line a baking sheet with parchment paper or wax paper and set aside.
- In a medium saucepan over medium heat, combine butter, sugar, and milk. Stir frequently until butter melts and the mixture comes to a full boil.
- Once boiling, cook for exactly 1 minute, then remove from heat immediately.
- Stir in vanilla extract and peanut butter until smooth and fully melted.
- Add oats and mix until evenly coated and combined.
- Using a spoon or cookie scoop, drop spoonfuls of the mixture onto the prepared baking sheet.
- Allow cookies to cool and set at room temperature for about 30–40 minutes or refrigerate to speed up the process.
- Store in an airtight container at room temperature for up to 5 days.
Notes
- For chewier cookies, reduce oats slightly; for firmer cookies, add a few more tablespoons of oats.
- You can use crunchy peanut butter for added texture.
- Do not overcook the sugar mixture — boiling longer than 1 minute can make the cookies dry and crumbly.

Ingredients
(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)
Butter
Unsalted butter adds richness and helps create that fudgy, chewy texture when combined with the sugar.
Sugar
Granulated sugar sweetens the cookies and helps form the syrup that binds everything together.
Milk
A splash of milk thins the mixture and helps dissolve the sugar, ensuring smooth, creamy cookies.
Peanut Butter
Creamy peanut butter gives these cookies their signature nutty flavor and smooth consistency. Use crunchy peanut butter for extra texture if you prefer.
Vanilla Extract
A touch of vanilla extract rounds out the sweetness and enhances the peanut butter flavor.
Salt
A pinch of salt balances the sweetness and brings out the nutty flavor.
Quick Oats
Quick oats (not old-fashioned) create the perfect chewy texture while allowing the cookies to set properly.
Directions
- Prepare your setup: Line two baking sheets with parchment or wax paper and set aside.
- Make the syrup: In a medium saucepan, combine butter, sugar, milk, and salt. Bring to a rolling boil over medium heat, stirring occasionally. Let it boil for 1 minute, then remove from heat.
- Add peanut butter and vanilla: Immediately stir in peanut butter and vanilla extract until smooth and fully melted.
- Mix in oats: Add the quick oats and stir until fully combined and evenly coated. The mixture should be thick and sticky.
- Scoop and shape: Using a spoon or cookie scoop, drop spoonfuls of the mixture onto the prepared baking sheets. Flatten slightly if you like a more traditional cookie shape.
- Set and cool: Let the cookies cool at room temperature for about 30–45 minutes, or until firm and set.

FAQs
Why are they called “no-bake” cookies?
Because they set up without needing to bake — the hot syrup cooks the oats and binds everything together.
Can I use old-fashioned oats instead of quick oats?
You can, but the texture will be rougher and chewier. Quick oats work best for soft, fudgy cookies.
Why did my cookies not set properly?
They may not have boiled long enough. Make sure the mixture reaches a full rolling boil for at least one minute.
Can I make these cookies vegan?
Yes — use plant-based butter and non-dairy milk.
Can I use natural peanut butter?
It works, but make sure it’s well-stirred and not too oily, as it can affect how the cookies set.
How can I make them less sweet?
Reduce the sugar slightly or use unsweetened peanut butter.
Do these need to be refrigerated?
Not necessarily — they set fine at room temperature, but refrigeration keeps them firmer longer.
How long do they take to set?
Typically about 30–45 minutes at room temperature, or 15–20 minutes in the refrigerator.
Can I double the recipe?
Yes, but make sure your saucepan is large enough to prevent boiling over.
Can I add chocolate chips?
Yes — stir them in once the mixture has cooled slightly so they don’t melt completely.

These Peanut Butter No-Bake Cookies are the ultimate quick and easy treat — sweet, chewy, and perfectly nostalgic.
