How fun are these rainbow marshmallows? They are perfect for a St. Patrick’s Day or Easter dessert.
Although, admittedly, it’s also makes me think of magical things like how this could totally be unicorn food for the soul. That is if sugar, sprinkles and sparkles make you smile like me.
So go ahead—grab the recipe and make some for those you love and spread the cheer. (Psst . . . please tell me that you have bought a thermometer like the one I suggested here, because you are going to need one. They aren’t costly, and you’ll find so many uses for it.)

Rainbow Marshmallows
Ingredients
- 1 1/2 water
- 3 tablespoons gelatin (3 packets)
- 2 cups sugar
- ½ cup water
- ¼ cup honey
- 1-2 drops pink food coloring
- 1-2 drops green food coloring
- 1-2 drops yellow food coloring
Instructions
Preparation: Lightly cover a 9x13 pan with nonstick spray; line with parchment paper. Lightly coat parchment paper with non-stick spray (first coat helps to keep the parchment paper in place).
Pour 1/2 cup water in to a stand mixer bowl fitted with the whisk attachment. Sprinkle gelatin on top. Set aside.
In the meantime, in a small medium sauce pan over medium heat, stir together remaining 1 cup water, sugar, and honey; cook until sugar dissolves. Once sugar dissolves continue to cook the mixture without stirring until temperature reaches 240 degress F, about 12-15 minutes. Remove from heat and transfer mixure to a heat proof bowl and allow to cool to 210 degrees F.
Pour slightly cooled syrup mixture into gelatin mixture; beat on low until combined. Increase speed to high and beat until thick and fluffy and mixture triples in volume, about 10 minutes. Working quickly, divide mixture into three separate bowls and mix in food color (one color to each bowl). Using a lightly oiled spatula, scrape and layer each color into prepared pan. Using a lightly oiled knife drag and swirl it through the mixture to create a marbled effect. Do not over do. Smooth top surface (surface may not be completely even). Set aside in a cool place, (not the refrigerator) for 8 hours or overnight.
Remove marshmallow from pan and peel away parchment paper. Lightly dust top and bottom of marshmallow with powdered sugar mixture. Lightly cover a serrated knife with non-stick spray and slice marshmallows into 1” cubes. Cover cut sides with powdered sugar mixture. Marshmallows will keep in an air tight container between layers of nonstick parchment for 3 to 4 days.
