Equipment

  • Large saucepan
  • Wooden Spoon or Silicone Spatula
  • 9x13-inch Baking Pan
  • Measuring cups and spoons
  • Mixing bowl (optional)
  • Shamrock cookie cutter

Ingredients
  

For the Rice Krispie Base:

  • 6 cups Rice Krispies cereal
  • 4 cups mini marshmallows
  • 3 tablespoons unsalted butter
  • 1 teaspoon vanilla extract
  • Green food coloring about 10–15 drops, or until desired color

Optional Decorations:

  • Sprinkles chocolate drizzle, or edible glitter for topping

Instructions
 

Prep Your Pan and Ingredients

  • Line a 9x13-inch baking pan with parchment paper. This makes it super easy to lift the treats out later.
  • Measure out your Rice Krispies, marshmallows, butter, and green food coloring so everything is ready to go.
  • Pro tip: Have your cookie cutter and decorations nearby if you plan to shape and decorate the treats—they’re easier to work with while the mixture is still warm.

Melt the Butter

  • Place 3 tablespoons of butter in a large saucepan over low-medium heat.
  • Stir gently until fully melted and smooth.
  • Pro tip: Keep the heat moderate to avoid browning the butter; you just want it melted and creamy.

Add Marshmallows

  • Add 4 cups of mini marshmallows to the melted butter.
  • Stir continuously until the marshmallows are fully melted and combined with the butter.
  • Pro tip: Use a silicone spatula or wooden spoon and keep stirring—this prevents lumps and ensures a smooth, stretchy base.

Add Vanilla and Green Coloring

  • Remove the pan from heat.
  • Stir in 1 teaspoon of vanilla extract.
  • Add green food coloring gradually, mixing until you reach your desired shade of green.
  • Pro tip: Start with 10 drops and add more if needed—you can always make it brighter, but it’s tricky to fix if it gets too dark.

Combine with Rice Krispies

  • Pour the Rice Krispies cereal into the marshmallow mixture.
  • Fold gently until every piece is coated evenly in the green, gooey goodness.
  • Pro tip: Don’t over-stir, or the cereal can get crushed and lose that perfect crispy texture.

Press Into the Pan

  • Transfer the mixture into your prepared baking pan.
  • Use a spatula (or a piece of parchment) to press it down evenly.
  • Pro tip: Lightly butter your spatula or hands to prevent sticking—this helps get a smooth, even surface for cutting or shaping.

Shape and Decorate

  • If you’re making shamrocks, let the mixture cool for 10–15 minutes—still slightly warm is ideal for cutting.
  • Use your cookie cutter to press out shamrock shapes, or cut squares if you prefer classic treats.
  • Decorate with sprinkles, chocolate drizzle, or edible glitter if desired.

Let Them Set

  • Allow the treats to fully set at room temperature, about 30 minutes.
  • Once firm, enjoy or store in an airtight container for up to 3 days.
