Ingredients
- 1 1/2 cups sugar
- 1/2 cup milk
- 1 stick (8 tablespoons) unsalted butter
- 1/4 cup unsweetened cocoa powder
- 3 cups old-fashioned rolled oats
- 1 cup smooth peanut butter
- 1 tablespoon pure vanilla extract
- Large pinch kosher salt
Directions
Line two baking sheets with wax paper or parchment.
Bring the sugar, milk, butter and cocoa to a boil in a medium saucepan over medium heat, stirring occasionally, then let boil for 80 seconds. Remove from the heat. Add the oats, peanut butter, vanilla and salt, and stir to combine.
Drop teaspoonfuls of the mixture onto the prepared baking sheet, and let sit at room temperature until cooled and hardened, about 30 minutes. Refrigerate in an airtight container for up to 3 days.
Notes
Sifting the cocoa powder before adding will make it easier to make the sauce. It is possible to use quick oats in place of rolled oats, but in my experience the cookies don't retain their shape as well.
Have a timer already preset to 80 seconds. The "wait while boiling" step is super important, and it's easy to become flustered and not time it precisely.
