INGREDIENTS
- 1/2 cup (1 stick) unsalted butter
- 2 cups granulated sugar
- 1/2 cup milk (whole or 2% works best)
- 4 tablespoons unsweetened cocoa powder
- 1/2 cup peanut butter (creamy or crunchy)
- 3 cups quick-cooking oats
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon salt
- Optional add-ins: 1/2 cup shredded coconut, chopped nuts, or chocolate chips
INSTRUCTIONS
First, prepare your workspace by laying out a sheet of parchment paper or wax paper on your counter. This will be where you place your cookies to cool and set. You’ll want to have this ready before starting because once the mixture is prepared, you’ll need to work quickly before it begins to harden.
In a medium-sized saucepan, combine the butter, sugar, milk, and cocoa powder over medium heat. Stir continuously until the butter is completely melted. Once the mixture reaches a rolling boil, let it cook for exactly one minute while stirring constantly.
Timing is crucial here—too short and your cookies won’t set properly; too long and they’ll become dry and crumbly.
After one minute of boiling, remove the pan from heat immediately. Add the peanut butter and stir until it’s fully melted and incorporated. Next, add the vanilla extract and salt, mixing well to combine all flavors evenly throughout the mixture.
Finally, add the oats (and any optional add-ins) to the chocolate mixture, stirring until everything is thoroughly coated. The mixture should be thick but still easy to drop from a spoon. Working quickly, drop spoonfuls of the mixture onto your prepared parchment paper.
You can use a cookie scoop or two spoons to form cookies about 2 inches in diameter.
Allow the cookies to cool at room temperature for about 30 minutes to 1 hour until they’re completely set. If you’re in a hurry, you can place them in the refrigerator to speed up the process.
Once set, these cookies can be stored in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.

FAQs
1. Why didn’t my cookies set properly?
The most common reason for cookies not setting is that the mixture didn’t boil long enough. Make sure to boil for a full minute after reaching a rolling boil. Another possibility is humidity—on very humid days, you might need to add a few extra tablespoons of oats to help them set.
2. Can I use old-fashioned oats instead of quick-cooking oats?
Yes, you can substitute old-fashioned oats, but the texture will be chewier and less uniform. If using old-fashioned oats, you might want to pulse them in a food processor a few times to break them down slightly.
3. Is there a substitute for peanut butter if I have allergies?
Absolutely! You can use any nut butter like almond or cashew butter. For nut-free options, sunflower seed butter or cookie butter work well as substitutes.
4. Can I make these cookies less sweet?
Yes, you can reduce the sugar to 1 1/2 cups without affecting the setting process too much. You might also try using dark cocoa powder for a less sweet, more intense chocolate flavor.
5. How do I know if I’ve cooked the mixture long enough?
Use a timer and start it once the mixture reaches a full rolling boil (bubbles all throughout, not just at the edges). One minute is typically perfect, but if you want to be precise, you can use a candy thermometer—the mixture should reach about 230°F (110°C).
