INSTRUCTIONS TO MAKE ST PATRICK’S DAY RICE KRISPIES TREATS
You will love how simple these rice krispies treats are to make!
Step One: Melt Butter and Marshmallows
- Melt the butter in a large pot over low heat.
- Then slowly add in the marshmallows, stirring continuously until they are completely melted.
Step Two: Add Cereal
- Next, remove the mixture from heat.
- Gradually add in the Rice Krispies continuously stirring to ensure it gets completely coated.

Step Three: Spread Mixture in a Pan
- Spray a 9″ x 13″ baking pan with cooking spray for easier removal.
- Next, add the marshmallow-cereal mixture to the pan and spread it out evenly.
Pro Tip: add cooking spray to the utensil that you’re using to spread the mixture in order to help prevent it from sticking.
Step Four: Cut Out Shamrocks (Two Ways)
There are two ways you can make shamrock-shaped Rice Krispies treats. I tired both, and I like the molding method better, although it is a bit stickier, lol. Molding them gives you smoother and more defined edges.
However, both ways will work fine. I share each method below.
To Mold Them
- Wait until the mixture has cooled just enough to where you can handle it without getting burned. Don’t wait until it is too cool, though. The warmer it is the easier it will be to mold it.
- Make sure you spray the cookie cutter to prevent sticking, and then start filling the cookie cutter with the mixture to form the shamrocks.

To Cut Them
- After the mixture has been spread in the pan, place it in the refrigerator for 1 hour to allow the Rice Krispies treats to set. This will make it easier to cut them with a cookie cutter.
- Once set, remove the Rice Krispies from the pan and then set them on a table or counter on a piece of parchment paper.
- Now use the cookie cutter to cut the shamrocks out.
Step Five: Melt Chocolate
- Next, add the green candy melts to a microwave safe bowl, and heat in 30 second intervals, stirring between each heat session, until the chocolate is fully melted. You could also use a doubler boiler or candy melting pot.
Step Six: Decorate
- Working with one treat at a time, use a piping bag, zip lock baggie, or a spoon to drizzle melted candy in zigzags across the shamrock Rice Krispies treat.
- Then, before the chocolate sets, sprinkle some gold dust over the melted chocolate.
- Repeat until all shamrocks are decorated.
And there you have it! Super soft and extra fun St. Patrick’s Day Shamrock Rice Krispies Treats that are so yummy!

FAQ for Rice Krispies Treats
Why Are My Rice Krispies Treats Hard?
The most common reason is melting the butter and marshmallows over high heat. Always cook the marshmallow mixture over low heat. It’ll take a few more minutes of your time, but it will be well worth it!
Secondly, when adding the mixture to the pan, don’t press the mixture down very hard. Instead, press just hard enough to get the cereal mixture spread around the pan.
How Do I Store Shamrock Rice Krispies Treats?
You can also freeze them for up to 3 months.
Can I Make Shamrock Rice Krispies Treats in Advance?
Why Are My Rice Krispies Treats Falling Apart?
Avoid this by following the original recipe instructions of 3 tbsps. of butter and 1 ten-ounce package of marshmallows.
Also, they are more likely to fall apart when they are warm.

Shamrock Rice Krispies Treats recipe

Delicious Rice Krispies Treats are cut into Shamrocks then decorated with melted chocolate and gold sprinkle dust in this fun and festive, easy-to-make Shamrock Rice Krispies Treats recipe!
Ingredients
- 3 tbsp butter
- 10 oz package mini marshmallows
- 6 cups Rice Krispies cereal
- 4 oz green candy melts
- Gold sanding sugar
Instructions
- Melt butter in a large pot over low heat.
- Slowly pour in marshmallows and stir until completely melted.
- Remove mixture from heat and stir in Rice Krispies cereal.
- Pour mixture into a 9x13 inch pan lined with parchment paper and use a buttered/greased spatula to spread it out.
- Refrigerate for 1 hour to help set them for easier cutting.
- Remove the parchment paper with the sheet of Rice Krispies, then set on a table or counter.
- Use the cookie cutter to cut shamrocks out. (see NOTES below for another method)
- Add the candy melts to a microwave safe bowl, then heat in 30 second intervals, stirring between each heating session, until the candy is fully melted.
- Working with one shamrock at a time, use a piping bag, Ziplock baggie, or a spoon to drizzle melted candy across the Shamrock Rice Krispies treats.
- Immediately sprinkle gold sanding sugar over the candy drizzle before it sets.
Notes
Another way to make shamrock shapes is to skip refrigerating the treats. Instead, once they are cool enough to handle without burning yourself, mold a handful of the mixture inside the cookie cutter, gently pressing to completely fill the cookie cutter. It helps if you add some cooking spray to the cookie cutter before beginning to help prevent sticking.
