Rice Krispie treats are a classic for a reason, they are buttery, sweet, crunchy, and very addicting! Add a little festive holiday flair to create these Shamrock Rice Krispie Treats and you really have a winner! They are pinch proof and oh so easy to make. You only need a fun shamrock shaped cookie cutter,  5 ingredients, and about 20 minutes to make this fun St. Patrick’s Day dessert idea.

Shamrock Rice Krispie Treats Recipe

Makes approximately 10-12 Shamrocks

Ingredients:

  • 6 cups Rice Krispies Cereal (off-brand works fine too!)
  • 10 ounces mini marshmallows
  • 3 tablespoon butter, cut into chunks
  • Green gel food coloring
  • White frosting

Additional tools needed:

  • 3″ Shamrock cookie cutter (We used the middle size shamrock in this set)
  • Tinfoil or wax paper
  • Non-stick cooking spray
  • Small sandwich baggy
  • 9×13 pan

Directions:

  1. Line a 9×13 pan with tinfoil or wax paper. If using tinfoil, spray with non-stick cooking spray.
  2. Add the mini marshmallows and butter to a large saucepan and heat on low/medium heat, stirring occasionally. Once the mixture is about 1/2 melted, add several drops of green gel food coloring. melted marshmallows in a bowl

  4. Pour the mixture into the prepared pan and gently press down evenly.
  5. Allow the treats to set prior to cutting.
  6. If you are pressed for time, place the treats in the fridge for 20 minutes to firm them up.
  7. Line a separate baking sheet with wax paper.
  8. Using the shamrock cookie cutter, cut the treats as close together as possible and place them on the prepared baking sheet. green shamrock rice krispie treats on waxed paper
  9. Heat the white frosting in the microwave for 10-15 seconds. You don’t want it liquidy but you do want it soft enough to drizzle over the treats.
  10. Scoop a few spoonfuls of the frosting into the sandwich baggy and make a small snip in the corner.
  11. Gently squeeze the frosting from the bag over the shamrocks going in a back and forth motion. icing drizzled shamrock rice krispie treats

Welcome. I'm Alea!

On Premeditated Leftovers I share simple recipes made with whole foods, practical shopping tips, time saving techniques, and meal planning strategies. I also share tips for minimizing food waste, so more of the food that is purchased ends up on the table.

While volunteering as a budget counselor, I realized that food is the element of most people’s budgets where they have the greatest control. I set out to develop low-cost recipes from scratch to prove it’s possible to create delicious meals on a limited budget. Eating well while spending less is about more than just creating recipes using inexpensive ingredients; it’s about creatively combining ingredients so you don’t feel deprived and are inspired to stick to your budget.
