Supplies and Ingredients you'll need
In addition to the purple food coloring, to make cereal treats, you'll need Rice Krispies cereal, marshmallows, and butter. That's it!
To make a smaller batch of treats, you'll need:
- 4 ⅔ cups Rice Krispies (Kellogg's brand preferred)
- 4 tablespoons salted butter (European style preferred)
- 10 ounces marshmallows (about 40 regular-sized OR 6 cups mini)
To make a larger batch of treats, you'll need:
- 7 cups Rice Krispies
- 6 tablespoons salted butter
- 16 ounces marshmallows (about 68 regular-sized OR 9 cups mini)
We recommend Jet-Puffed marshmallows, as different brands have different textures and weights. Check out our marshmallow conversion chart for perfect treats.
You'll need purple food coloring. (See below for more details.)
I also recommend spraying bowls and spatulas with non-stick spray to deal with the stickiness.
purple food coloring
Any food coloring, either liquid or gel, will work with this recipe. Whereas other colors are more forgiving, note truly vibrant purple is difficult to achieve with food coloring.
Gel paste food coloring, which is more concentrated, is available in craft stores, online, and some supermarkets. I recommend Americolor Soft Gel Paste Electric Purple.
You can also use a mix of primary liquid coloring (blue and red), found in many supermarkets, to achieve the secondary purple color.
Add the Rice Krispies to a greased, large bowl (use cooking spray or butter).
Line your baking pan with non-stick foil or lightly-greased parchment or foil. Set aside.
To make Rice Krispie Treats on the stove-top:
Start to melt the butter over low heat. Add the marshmallows and heat, stirring frequently, until almost all of the marshmallows have melted.
Remove from the heat and stir well until very smooth.
To make Rice Krispie Treats in the microwave:
Place the marshmallows and butter in a greased, microwave-safe bowl.
Heat for 1 minute and let sit for a couple minutes. Stir very well until smooth and melted. If needed, microwave for an additional 15 seconds.
mix up your treats:
Add a few drops of purple gel paste food coloring OR a combination of red and blue liquid food coloring, and stir well. Add additional drops to get your preferred shade. Stir very well.
Here, I used gel paste food coloring, a mix of Regal and Electric Purples. The gel coloring I used made a purple with blue tint.
Whereas here I used red and blue liquid food coloring, with slightly more red, to make a warmer purple.
With a greased spatula, scrape the mixture over the cereal and stir until well combined.
Transfer to the prepared baking pan and gently press evenly.
Let sit for 2 hours before cutting into squares.
