Frankenstein has popped his head up around these parts one time before, and let’s just say he became the most infamous sweet-on-a-stick the Internet has ever seen. While Frankie and mallows made quite the dynamic duo, it was time to up the sticky-meets-sweet combination in this tried-and-tested recipe for the ultimate Frankenstein Rice Krispie Treats.

How to Make Soft and Chewy Rice Krispie Treats

It all comes down to my not-so-secret 8:8:8 ratio for perfectly soft and chewy cereal treats:

  • 8 Tablespoons unsalted butter
  • 8 cups mini marshmallows
  • 8 cups Rice Krispies cereal

Follow this easy-to-remember ratio and you’ll be snacking on extra-soft cereal treats that are equal parts chewy and delicious.

Why Are My Cereal Treats Hard?

I’m so glad you asked! There are two main culprits for tough treats:

  • Not enough fat (ie. butter)
  • Too high of heat while cooking

Following my 8:8:8 ratio will solve for the first issue, but then it’s important to keep an eye on that burner and not let the mallows get too hot or the sugars will cool much firmer than desired.

Prep Time 20 mins
Cook Time 10 mins
Servings 12 servings

Ingredients 

  • 8 Tablespoons unsalted butter
  • 8 cups mini marshmallows
  • Green food coloring
  • 8 cups Rice Krispies cereal
  • Pretzel sticks
  • 1 cup chocolate melting wafers
  • Chocolate sprinkles
  • Candy eyes

Instructions 

  • Add the butter to a large heavy-bottomed pot set over medium-low heat. Once the butter has melted, stir in the marshmallows and cook, stirring, until the mixture is smooth.
  • Add food coloring until the mixture reaches your desired color then stir in the cereal until well-coated. Immediately pour the mixture into a 13×9-inch baking pan. (The pan does not have to be greased.) Flatten the cereal into an even layer then let the treats cool completely, about 15 minutes.
  • Once the treats have cooled, invert them onto a cutting board and cut them into 12 or 18 rectangles.
  • Break each pretzel stick in half, and then insert each half into the sides of the treats to form the "bolts" in Frankenstein's neck.
  • Melt the chocolate per the package instructions until smooth. Dip the tops of the treats into the melted chocolate, and then immediately top with sprinkles.
  • Use the remaining chocolate to adhere the candy eyes and pipe mouths. Let the treats set until the chocolate has fully hardened, about 10 minutes, then serve.
