How to Make Reese’s Cereal Treats

  1. Melt the butter and peanut butter in a large pot over medium heat. I prefer a non-stick pot like this Hexclad for this use.
  2. Stir in the marshmallows and keep stirring until completely melted and smooth.
  3. Remove from heat and fold in the Reese’s Puffs cereal. Work quickly to combine before the mix cools.
  4. Press the mixture into a greased 9×13-inch pan using a buttered spatula or parchment paper. – This lasagna pan is my go to. It’s just so damn pretty!
  5. Melt the chocolate chips in a microwave-safe bowl in 30-second intervals until smooth. Drizzle over the top. It make it really easy if you pour the chocolate into a piping bag, or a Ziploc bag and snip the tip to create even drizzles.
  6. Add any extra toppings if you’re feeling fancy. Let cool for at least 30 minutes before slicing.
