1. Line baking sheets with parchment paper or wax paper.
2. Make syrup: In a saucepan, combine butter, sugar, milk, and cocoa powder. Bring to a boil over medium heat, stirring constantly.
3. Boil 1 minute once it reaches a full rolling boil (set a timer!).
4. Remove from heat. Stir in peanut butter and vanilla until smooth.
5. Add oats: Stir in quick oats until fully incorporated.
6. Drop by spoonfuls onto prepared sheets (about 1½ tbsp per cookie).
7. Cool 15–20 minutes until set. Store in an airtight container at room temperature.

💡 Pro Tips:
– Use quick oats, not old-fashioned—they bind better.
– If cookies don’t set, the mixture didn’t boil long enough. Reheat and boil 30–60 seconds more next time.
– For gluten-free: Use certified GF oats.
– For dairy-free: Use plant-based butter and milk.
