Chocolate No-Bake Cookies

Spread a piece of aluminum foil or waxed paper out on the counter ahead of time.

Combine the sugar, cocoa powder, milk, and butter in a saucepan over high heat. Bring to a boil and let boil for exactly one minute after it comes to a full boil. Remove the pan from the heat.

Stir the vanilla, peanut butter, and oatmeal into the sugar mixture and mix quickly to combine.

Drop the cookie batter by spoonfuls onto the foil or waxed paper. Let cool completely. Store the cookies in an airtight container.
