Ingredients
Base Ingredients:
- 1/2 cup (115 g) unsalted butter
- 2 cups (400 g) granulated sugar
- 1/2 cup (120 ml) milk
- 1/4 cup (25 g) unsweetened cocoa powder
- 1 teaspoon vanilla extract
- 1/2 cup (125 g) creamy peanut butter
- 3 cups (270 g) quick oats (you can also use old-fashioned oats for a chewier texture)
- A pinch of salt
Instructions
- Prepare your workspace
Line two baking sheets with parchment paper or wax paper. This will be where you’ll drop your cookies to set. Make sure your oats and peanut butter are ready before you start heating the mixture, as the process moves quickly once the chocolate mixture begins to boil. - Melt and mix the chocolate base
In a large saucepan over medium heat, combine the butter, sugar, milk, and cocoa powder. Stir frequently until the butter melts completely and everything is smooth. Bring the mixture to a rolling boil — that means it should bubble vigorously across the surface — and let it boil for 1 full minute. Boiling for less than a minute can cause your cookies not to set properly, while boiling too long can make them dry and crumbly. - Add flavor and texture
Remove the saucepan from heat. Stir in the peanut butter, vanilla extract, and salt until everything is melted and combined. The peanut butter will give the cookies a rich, creamy texture. - Mix in the oats
Add the oats to the warm mixture and stir until they are fully coated. The mixture should be thick and glossy, and you should be able to scoop it easily without it running off your spoon. - Form the cookies
Using a spoon or a cookie scoop, drop spoonfuls of the mixture onto your prepared baking sheets. You can make them as small or large as you like, but aim for even sizes so they set consistently. - Let them set
Allow the cookies to cool and firm up at room temperature for about 30–40 minutes. If you’re in a hurry, you can place the trays in the refrigerator for 15–20 minutes. Once set, the cookies will be firm but still soft and chewy on the inside.
Tips for the Perfect No-Bake Cookies
- Use fresh oats: Stale or old oats can result in dry cookies.
- Timing matters: The one-minute boil time is crucial — it helps the sugar reach the right stage to hold the cookies together once cooled.
- Smooth or chunky peanut butter? Smooth peanut butter gives a creamier texture, but if you prefer extra crunch, chunky peanut butter works great too.
- Storage: Keep cookies in an airtight container at room temperature for up to 5 days or refrigerate them for a firmer bite. They can also be frozen for up to 2 months — just let them thaw before serving.
Variations
- Coconut twist: Add ½ cup of shredded coconut to the oat mixture for extra texture.
- Nutty crunch: Mix in chopped almonds, walnuts, or pecans.
- Chocolate lovers: Sprinkle chocolate chips on top right after scooping for a double-chocolate version.
- Healthier option: Use coconut sugar, almond milk, and natural peanut butter for a lighter version.
