Ingredients Method Notes

Ingredients
  

  • 2 cups granulated sugar or 1½ cups granulated + ½ cup brown sugar
  • ½ cup unsalted butter
  • ½ cup whole milk
  • ¼ cup unsweetened cocoa powder
  • 1 cup creamy peanut butter the hero, don't skip it
  • 1 tsp vanilla extract
  • ¼ tsp salt
  • ⅛ tsp cream of tartar
  • 3 cups quick-cooking oats

Method
 

  1. Line two baking sheets with parchment. Measure everything before touching the stove, this moves fast and waits for no one.
  2. Combine butter, milk, sugar, cocoa, salt, and cream of tartar in a medium heavy-bottomed saucepan over medium-low heat. Whisk until the butter melts and the sugar fully dissolves. Don't rush this part, it matters.
  3. Raise the heat to medium. Bring to a full rolling boil, then hold it for exactly 1 minute (or watch for 230°F–234°F).
  4. Pull from the heat immediately. Stir in peanut butter and vanilla until smooth and glossy.
  5. Fold in oats. Now let it sit for 5 minutes, this gives the oats time to absorb moisture and thicken before you scoop. Skip this, and they'll spread flat.
  6. Drop heaping tablespoons onto parchment fast, it sets as it cools.
  7. Leave them alone for 30 minutes at room temperature. Walk away. Don't poke them.

Notes

  1. If they won't set: The mixture didn't boil long enough. Timing starts once it reaches a full rolling boil across the whole surface.
  2. If they're dry and crumbly: It boiled too long. Keep it to 60 seconds.
  3. Old-fashioned oats: Pulse them a few times in a food processor first. Whole rolled oats stay chewy and loose.
  4. Humidity: On humid days add 10 to 15 seconds to the boil.
  5. Storage: Keep in an airtight container at room temperature up to 1 week, or freeze up to 3 months.
