It's easy to create any color Rice Krispie Treats! Simply mix in food coloring .
black Rice Krispie Treats
To make black Rice Krispie Treats, start with our BEST, taste-tested Rice Krispie Treat recipe and mix food coloring into the marshmallow and butter mixture.
However, black is a bit trickier. Because it's so dark, it takes a good bit of food coloring, and black liquid food coloring isn't easy to find. Therefore, we recommend specific black gel paste food coloring that will maximize color with the fewest drops to not affect the taste of the treats.
Because to achieve dark colors requires so much food coloring, do keep in mind that the food coloring can temporarily stain hands and, more importantly, temporarily stain mouths and teeth.
more Rice Krispie Treats you'll love
You only need a few ingredients to make these no-bake treats.
- butter - After extensive taste-testing, we found using European-style salted butter gives the very best flavor.
- crisp rice cereal - Kellogg's Rice Krispies is our go-to cereal when making treats.
- marshmallows - You can use mini or regular marshmallows just be sure to use a fresh package.
- Old marshmallows will be too dry and will cause your treats to be dry.

which food coloring do I use?
For the best coloring with little effect on altering the taste of the treats, I suggest using GEL paste food coloring. You can find gel pastes in the craft store. Specifically, I recommend using Americolor Soft Gel Paste Super Black, found online.
TOOLS you'll need:
Extra large mixing bowl -- It's best to have room to mix the cereal with the marshmallow mixture. Grease the bowl with butter or non-stick spray.
Medium sauce pan OR large microwave-safe bowl -- You may melt the butter and marshmallows either on the stove-top or the microwave.
8-inch or 9-inch square baking pan -- I prefer the smaller size for thicker treats.
silicone spatulas -- My personal preference for mixing treats.
Non-stick cooking spray and non-stick foil --It helps to spray your pan, bowls, and spatulas with cooking spray. You may also line the baking pan with non-stick foil.
Add the Rice Krispies to a greased, large bowl.
Line an 8-inch or 9-inch baking pan with non-stick foil or parchment paper OR grease well.
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 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.
Add food coloring
Add a few drops of black food coloring to the marshmallow mixture and stir well. Continue adding drops and stirring until you reach the desired shade.
With a spatula, scrape the mixture over the cereal and stir until well combined. We do NOT recommend pouring the cereal into the hot marshmallow mixture because your treats will become soggy.
Transfer to the baking pan and flatten gently.
Let the treats cool and set 1 to 2 hours before cutting into squares.
Store your treats in an airtight container at room temperature for up to a week.
To keep them longer, you can place the treats in a zip-top bag, remove all the air, and freeze them for up to 3 months.
