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!

ingredients

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.

supplies

You'll need either and 8 or 9-inch square baking pan for a smaller batch, or a 9 x 13-inch baking pan for the larger batch.

Line your baking pan with parchment paper or non-stick foil.

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 liquid and gel paste food coloring

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.

Instructions

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.

Storage

Store these treats at room temperature in an airtight container for up to 7 days.

You can package the treats in a single layer in gallon-size zip-top bags and freeze them for up to 3 months. Thaw the treats in the bag on the counter for at least one hour before removing them from the bag to keep condensation from forming on the treats.

Notes

We recommend Jet-Puffed brand marshmallows. 
To make on the stove-top, melt the butter and marshmallows over low heat and stir. Remove from heat when about 75% of the marshmallows are melted. Then stir and use the residual heat to fully melt the marshmallows. 
To make a 9 x 13 inch baking pan batch, use 16 ounces of marshmallows, 6 tablespoons salted butter, and 7 cups of Rice Krispies. 
While any food coloring will work, we recommend Americolor Soft Gel Paste brand (Electric Purple and/or Regal Purple) found online and in craft stores. OR use red and blue drops of liquid food coloring, found in most supermarkets.
