    How to make Watermelon Rice Krispie Treats

    Watermelon rice krispie treats are decorative and delicious 5 ingredient no bake dessert bars. They are made easily with food coloring, rice krispie cereal, butter, marshmallows and chocolate chips. They taste just like original rice krispies, but with a little pop of chocolate.

    It is not too difficult to make colored rice krispie treats. In fact, you can do it with food coloring like we will do with these or these green rice kripsie treats, or these rainbow rice krispie treats.. Or you can use colored marshmallows like these Peeps Rice Krispie Treats. You can even use cake mix or jello to get colored treats.

    Variations

    These treats are all about being creative, so you can mix up the way you make them if you want. A few changes you can make are:

    • use little dots of chocolate icing instead of chocolate chips.
    • Use Watermelon Jello to make the pink part of these treats instead of food coloring if you want them to be flavored to taste the way they look
    • Use Starburst watermelon jello for the green rind of the treats (it is a green colored jello) instead of food coloring.
    • use marshmallow fluff for your treats instead of melting marshmallows.

    Supplies

    • spatula
    • large stock pot or Microwave Safe Bowl
    • Measuring Cup
    • 9 x 13 baking pan

    Ingredients

    • 6 Cups Rice Krispies Cereal
    • 16 oz of Jet Puff Marshmallows
    • 4 Tbs Salted Butter
    • (optional) non-stick canola oil spray
    • Food Coloring

    Instructions

    Before getting started make sure you have everything you need. Also pre-grease you pan, spatula and bowl because the marshmallows are super sticky and this will make it easier to work with.

    Step One

    To make things go more quickly, we used the microwave for this recipe but you can of course use the stove top method as well. Whichever method you prefer is fine.

    Place 1 ½ tablespoons of butter in a large microwave safe bowl and heat for about 1 minute. You want your butter completely, or at least mostly, melted.

    Add about ⅓ or 5 oz of a bag of marshmallows to the melted butter. Stick them into the microwave and heat for another minute. Check to make sure the marshmallow is melted enough to mix. It may need an additional 30-45 seconds.

    Step Two

    Once the marshmallows are melted enough, mix them in with your butter and add in green food coloring. Stir them with your spatula until you have a beautiful, bright green marshmallow mix.

    Now it's time to add in your Rice Krispies. Pour about 2 measured cups into the green mix and stir. Make sure your Rice Krispies and marshmallows are completely mixed and completely green.

    You may need to add in more food coloring to get the desired level of green color. Place the bowl of green mix into the fridge and move to the next layer. We put it in the fridge so it will cool more quickly and make it easier to mold later in the process.

    Step Three

    You will mostly repeat Step One with a few variations. You will need to melt 2 ½ tablespoons of butter and mix with 11 oz or ⅔ a bag of marshmallows. The heating time on these will both be a bit longer than with the first step.

    Add in pink food coloring this time along with 4 cups of Rice Krispies. Mix everything together, adding in more pink food coloring as needed. As unappetizing as it may sound, we like to go for a Pepto-bismol shade of bright pink.

    Once mixed, place this bowl to the side and remove the bowl of green mix from the fridge. You do not put the pink mix in the fridge. You will still want it to be a bit warm to allow the layers to melt together.

    Step Four

    Spray a 9' pie pan with canola oil or your preferred flavorless cooking spray. Scoop your green mix from it's bowl and place it in the pie pan. We found this easier to do in segments.

    You can try and use a spatula for this part but we found it easier to just use our hands. Take each section of the green mix and form it into a ring around the inside of the pie pan.

    Once you have a full ring, grab you bowl of still warm pink mix. Scoop the whole mix and stick it right in the center of the pie pan and green ring.

    You can use your spatula for this part. Smash and spread the pink mix to fill the empty area in the middle of the green ring until both color layers meet.

    Take about ¼ cup of chocolate chips and sprinkle them over the pink area and press them into the mix with a spatula. These are you watermelon seeds.

    Step Five

    Set your entire watermelon masterpiece to the side, or in the fridge again, and allow to cool. Once it has cooled, you can use a sharp knife to cut it into wedges. You should be able to get about 8 pie shaped wedges from a single serving.

    Enjoy!
