Green Rice Krispies Treats With Lime Jell-O

Make these green Rice Krispie treats for St. Patrick’s Day, Easter dessert, or for a fun birthday party treat. The secret is lime Jell-O!

This isn’t just any ol’ Rice Krispies Treats recipe – this one includes a fun twist using Lime Jello for added flavor. They are so bright and festive, everyone is going to love them.

Green rice krispies made with lime jello this idea now...

Colorful Rice Krispie Treats

My idea for adding jello mix to Rice Krispies Treats and creating Strawberry Rice Krispies Treats was such a hit with my family (and you!) that I had to try it for St Patrick’s Day too. And it works just as well.

If you and your kids love Rice Krispies treats, this is such an easy variation and so much fun. It’s no harder than making regular crispy treats.

In fact, Lime Jello Rice Krispies Treats are a perfect recipe for inviting your kids to help out in the kitchen. They can stir, pour, and even pat down the rice krispies treats into the pan. Even small children will love helping you “smoosh” the crispy treats into the pan and it will save you from getting your fingers sticky!

Green Rice Krispie Treats Supplies & Ingredients

This recipe only makes one 9×13-inch pan. Depending on how you cat the treats, it makes about 2 dozen squares. If you are going to be feeding a lot of kids at a party, you might want to double the recipe (or just cut them up smaller).

What You’ll Need for Lime Rice Krispies Treats:

  • Rice Krispies (use gluten-free if needed)
  • Mini Marshmallows
  • Lime Gelatin
  • butter or margarine (I use butter)
  • vanilla extract
  • Green Food Coloring (optional)

Optional Add-Ins

Here are a few things that I didn’t use, but thought about adding later. Try a few of them to jazz up your St. Patrick’s Day treats.

  • St. Patrick’s Day Sprinkles
  • Multi-colored marshmallows
  • White Chocolate Drizzle
  • Edible Shamrock Decorations

How To Make Lime Jello Rice Krispies Treats

Here are some step-by-step pictures of the entire process so you can see how easy they are to make. I have all the steps in a printable recipe card at the bottom of this post.

First, here are the pictures along with some extra tips that I wanted to share with you.

The very first thing you need to do is gather all of your ingredients together. This recipe comes together very quickly, especially if you already have everything you need sitting on the countertop.

Melt the Butter

Then, melt the butter over medium-low heat. Melt it slowly so that it doesn’t burn.

Add Marshmallows

Add the marshmallows. Just let them sit for about 30 seconds with the heat turned down to low.

There’s something fun about watching marshmallows melt, isn’t there?

mini marshmallows

Stir it gently so that it doesn’t burn on the bottom of the pan. If you overmix the marshmallows, the treats will have a firmer texture, so be very careful as you stir them.

Add Vanilla and Lime Jello

Next, add the vanilla extract and lime gelatin.

Adding lime jello to melted butter and marshmallows

Stir this mixture. Then, remove it from the heat before the marshmallows are completely melted. (Overheating the marshmallows will make them tough, which equals  hard Rice Krispies treats.)

Keep stirring – off the stove – until the marshmallows are melted and the mixture is smooth.

Optional: Add Green Food Dye

Now, do you see how it’s light green in the photo above? The lime gelatin gives a nice flavor but it’s not super colorful. Especially when you add rice krispies in the next step. If you want, you can add some green food coloring for more color in your Lime Jello Rice Krispies Treats. For a vibrant green color, try my favorite food color.

Now that’s better! Just look at that bright green color!

Mix in Rice Krispies

Add the Rice Krispies and gently stir to combine.

Dump/spoon into a greased 13x9x2″ pan.

Pat it down gently with your hand – just enough to smooth out the big bumps. I recommend greasing your hand and doing it that way – it’s too sticky to use a spatula easily.

Let Sit

Let your Lime Jello Rice Krispies Treats sit for an hour or two. This allows your treats to cool and firm up while reducing the sticky factor. I prefer to let them sit on the countertop at room temperature, but you can also put them in the refrigerator.

If you chill them, they will have a tougher texture. I like them chewier, that’s why I let them sit at room temperature.

When you’re ready, cut into squares and enjoy your Lime Rice Krispies Treats!

At this step, you could also use cookie cutters to cut them into Shamrocks or other festive shapes.

How To Store Lime Rice Krispie Treats

If you want the rice crispy treats to last the longest, you should store them in the refrigerator in a sealed container or plastic bag.

No matter which container you use, place a sheet a parchment or wax paper between each layer so that they don’t stick together.

They will last about a week if you store them in the fridge.

      I really love your photo’s! They certainly show a great description of making these treats! I have many boxes of rice krispies right now from a coupon deal that happened last summer. I’ve donated some, but was looking for some ideas of how to use what I have left. I really love this idea and I think it will go over well with my family! Thank you for sharing…. they sound yummy 🙂

      LOL…so I went and bought the stuff to make these today, right? And I’m in the kitchen and hubby and I are chuckling about them. I put them in the pan, and cut out a bunch of clovers and he snags a piece of the area that didn’t get cut. Gobbles a whole bunch and declares them nom nom nom worth and grins wide…..
      His teeth were all green as well as his tongue and lips.

      I just started laughing and couldn’t stop.

      It was pretty funny.

      I just made these for my daughter’s class at nursery school – and they were fantastic! Not that sweet to eat, and the green colour was great and most importantly – not difficult to make at all. I had to double the recipe for the number of kids in the class but still only used 1 bottle of good colouring.
      Your tip about using greased hands to pat the mixture down in the in pan was a life-saver!
      I only left the mixture in the pan for about an hour and albeit that it sliced well, the treats still came out quite sticky, so if anyone else is trying the recipe, I would recommend leaving it in the pan for longer if possible (maybe overnight) – just ensure that you do grease the pan properly so that you can take the treats out easily.
      Thanks again for a lovely St. Patrick’s Day treat! 🙂

      This is a great idea. Have you tried to use chocolate pudding instead of jello? I just wondered if that would work too.

        I don’t think pudding would work, Jackie. It’s a very different texture than jello.
