Ingredients for Peanut Butter No Bake Cookies
Below are all the ingredients you need to make a batch of soft, chewy no-bake cookies.
Main Ingredients
- ½ cup unsalted butter (diced for quick melting)
- 1 ¾ cups granulated sugar
- ½ cup milk (any milk works—dairy or non-dairy)
- ½ cup creamy peanut butter (avoid natural “stir-only” peanut butter)
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- 3 cups quick-cooking oats
Optional Mix-Ins
- Mini chocolate chips
- Chopped peanuts
- Shredded coconut
- Butterscotch chips
- M&M–style candies
Ingredient Notes (Substitutions & Healthy Swaps)
Peanut butter: Use regular creamy peanut butter for the right consistency. Natural peanut butter tends to separate, causing the cookies not to set properly. For a peanut-free version, sunflower seed butter or almond butter also works well.
Oats: Quick oats are ideal because they mix smoothly into the syrup. Old-fashioned rolled oats make a chunkier cookie, but still work if that’s what you have.
Milk: The recipe is very flexible; almond milk, oat milk, soy milk, or regular dairy milk will all work.
Butter: If you prefer a dairy-free version, replace butter with vegan butter sticks.
Sugar: Granulated sugar sets the cookies properly. Using less sugar or swapping with liquid sweeteners may prevent the cookies from firming.
Add-ins: Feel free to customize! Stir chocolate chips in once the mixture cools slightly so they don’t melt completely.
Step-by-Step Instructions
These easy no-bake cookies come together in six simple steps.
Step 1: Prepare Your Baking Sheets
Line two baking sheets with parchment paper or silicone mats. This prevents sticking and makes cleanup fast.
Step 2: Melt the Butter
In a medium-sized saucepan, melt the butter over medium heat. Cutting the butter into pieces helps it melt faster and more evenly.
Step 3: Add Sugar and Milk
Once the butter has melted, whisk in the sugar and milk. Stir continuously until the mixture turns smooth and begins to bubble.
Step 4 : Boil the Syrup
Bring the mixture to a full rolling boil and let it boil for about 1½ minutes.
If you use a thermometer, aim for around 230°F (110°C). This step is essential — boiling the syrup long enough is what allows the cookies to firm up when cool.
Step 5: Stir in Peanut Butter and Oats
Remove the saucepan from heat. Quickly stir in the peanut butter, vanilla, and salt until smooth.
Then fold in the quick oats until every grain is coated and the mixture thickens.
Step 6: Scoop and Let Set
Use a cookie scoop or two spoons to drop rounded scoops onto your lined baking sheets. Let them set at room temperature for 20–30 minutes.
If you need them ready sooner, pop the trays in the fridge to speed things up.

Pro Tips for Success
- Boil exactly 90 seconds—too long and the cookies become dry; too short and they won’t set.

- If the cookies are too soft, chill them for 20–30 minutes.
- If they turn out crumbly, next time shorten the boiling time slightly.
- Avoid natural peanut butter because the oil separation affects setting.

FAQ About Peanut Butter No Bake Cookies
Do these cookies really not need baking?
Correct — no baking is required! The boiled sugar-butter-milk syrup binds the oats and peanut butter together as it cools. Once the syrup reaches the right temperature, the cookies firm up naturally without going in the oven.
Why didn’t my no-bake cookies set properly?
The most common reason is that the mixture didn’t boil long enough. The syrup must reach the right temperature to solidify as it cools. If the cookies turned out soft or sticky, simply refrigerate them to help them firm up. Next time, boil the mixture for a full 90 seconds.
Can I use natural peanut butter?
It’s better to use regular creamy peanut butter. Natural peanut butter tends to separate and has a higher oil content, which prevents the cookies from setting properly. If you only have natural peanut butter, stir it extremely well and expect a slightly softer cookie.
Can I make these cookies gluten-free?
Absolutely, simply use certified gluten-free quick oats. All other ingredients are naturally gluten-free.
Can I add chocolate to this recipe?
Yes! You can add cocoa powder to the syrup, fold chocolate chips into the mixture once it cools slightly, or drizzle melted chocolate on top once the cookies have set.
