When the spring flowers begin to bloom and the grocery store aisles fill with pastel-colored candies, there is one iconic treat that signals the arrival of Easter: Peeps. While these sugar-coated marshmallows are a classic in the Easter basket, they are even better when transformed into a gooey, crunchy, and multi-colored masterpiece. Our Rainbow Peeps Rice Krispie Treats take the nostalgia of a childhood favorite and elevate it with striking layers of purple, pink, blue, and yellow. This no-bake recipe is not only a visual showstopper for your holiday brunch but also a delightful sensory experience. The subtle sweetness of the Peeps combined with the buttery crunch of toasted rice cereal creates a dessert that is as delicious as it is Instagram-worthy. Whether you’re a seasoned baker or looking for a fun kitchen project with the kids, these bars are the perfect way to celebrate the season.

Why You’ll Love This Recipe
You are going to fall in love with these Rainbow Peeps Rice Krispie Treats for several reasons. First, the visual appeal is unmatched; the distinct, vibrant layers make them stand out on any dessert table far more than a standard tan cereal bar. Second, it is a fantastic way to use up those extra Peeps that inevitably find their way into your home during April. Third, this is a 100% no-bake recipe, making it ideal for busy holidays when your oven is already occupied by a glazed ham or roasted lamb. Finally, the texture is incredibly soft and gooey, thanks to the specific sugar content in Peeps marshmallows which provides a slightly different, more decadent “pull” than traditional marshmallows.
What Is A Rainbow Peeps Rice Krispie Treat?
A Rainbow Peeps Rice Krispie Treat is a creative variation of the classic American cereal bar. Traditionally made with plain white marshmallows, butter, and puffed rice cereal, this version substitutes the standard marshmallows with colorful Peeps. Peeps are marshmallow candies coated in colored sugar, which, when melted, provide both the adhesive for the cereal and a vibrant dye for the bars. By melting each color separately and layering them in a pan, you create a “rainbow” effect. It’s a festive, seasonal twist that combines the airy crunch of Rice Krispies with the playful, sugary essence of the world’s most famous Easter candy.
Ingredients you will need
To achieve the perfect balance of flavor and structural integrity, selecting the right ingredients is key. You will need:
- Peeps Marshmallows: This recipe calls for blue bunnies, pink bunnies, purple chicks, and yellow chicks. You’ll need approximately one 85g package of each color. The chicks and bunnies melt down similarly, so feel free to mix and match shapes as long as the colors are distinct.
- Rice Krispie Cereal: Stick with the classic toasted rice cereal for that iconic crunch. Ensure your cereal is fresh; stale cereal will ruin the texture of the bars.
- Unsalted Butter: Using high-quality unsalted butter allows you to control the saltiness. Room temperature butter melts more evenly with the marshmallows.
- Vanilla Frosting: A simple tub of store-bought vanilla frosting acts as the “glue” for your festive toppings and adds a creamy contrast to the crunchy base.
- Festive Sprinkles: Look for spring-themed sprinkles with pastels, bunnies, or egg shapes to really lean into the Easter aesthetic.
Ingredient Substitutions & Tips
If you cannot find specific Peeps colors, you can easily substitute other hues like orange or green to fit your theme. For those with dietary restrictions, vegan marshmallows and a plant-based butter substitute work remarkably well, though the colors may be slightly less neon. If you want a more “gourmet” flavor, consider adding a teaspoon of pure vanilla extract or a pinch of sea salt to each colored layer as you melt it. For the cereal, while Rice Krispies are the standard, you could experiment with Cocoa Krispies for a “chocolate-covered Peep” flavor profile, though this will obscure the rainbow colors.
Step-by-Step Instructions
Creating these layers requires a bit of patience, but the process is very straightforward.
- Preparation: Start by greasing an 8×8 inch or 9×9 inch square baking pan. Use a generous amount of butter or a high-quality nonstick cooking spray. For even easier removal, line the pan with parchment paper, leaving an overhang on the sides.
- The First Layer (Purple): Place the purple Peeps chicks into a medium-sized, microwave-safe glass bowl. Add 1 tablespoon of butter. Microwave on high for 30 seconds. The Peeps will puff up significantly—this is normal! Remove and stir. If they aren’t fully melted, microwave for another 15 seconds.
- Mixing: Immediately pour 1.5 cups of the rice cereal into the melted purple mixture. Use a silicone spatula (greased with a little butter) to fold the cereal in until every piece is coated in purple marshmallow.
- Pressing: Transfer the purple mixture into the prepared pan. Press it down into an even layer. Pro Tip: Use a small piece of greased parchment paper to press the mixture down to keep your hands clean and prevent sticking.
- Repeating the Process: Clean your bowl or use a fresh one. Repeat the melting and mixing process for the yellow, pink, and finally the blue Peeps. Layer each new color directly on top of the previous one, pressing gently to ensure they bond without crushing the cereal.
- Finishing Touches: Once all four layers are in the pan, let them cool for at least 20 minutes. Spread the vanilla frosting over the top layer.
- Decorating: Add your sprinkles and any leftover Peeps on top. Allow the bars to set for another 30 minutes before using a sharp, greased knife to cut them into 16 squares.
Expert Baking Tips
To ensure your treats are “bakery quality,” follow these professional tips. First, do not over-microwave the Peeps. Overheating the sugar can cause it to become hard and brittle once it cools, leading to a “rock-hard” treat rather than a gooey one. Second, avoid packing the mixture too tightly into the pan. If you press too hard, the bars will be dense and difficult to chew. Aim for a light press just to make the layer level. Lastly, always grease your tools. Marshmallow is incredibly sticky; greasing your spatula and even your hands will make the assembly process ten times easier and much less frustrating.
The Science of Melting Peeps
Have you ever wondered why Peeps behave differently than standard marshmallows? Peeps are coated in a fine layer of colored carnauba wax and sugar. When heated, this sugar coating melts into a concentrated syrup, which is why Peeps treats often feel slightly denser and more “candied” than those made with Jet-Puffed marshmallows. Furthermore, the air bubbles in Peeps are slightly different, leading to a massive expansion in the microwave. Understanding this helps you realize why the 30-second interval is so important—it manages the heat so the sugar melts without caramelizing (burning), preserving that bright, neon Easter color we all love.
Serving Suggestions
These treats are best served at room temperature on a clean, white platter to make the rainbow colors “pop.” They are a hit at children’s Easter parties, but they also make a whimsical addition to a sophisticated spring tea. For a fun “Easter Sundae,” try placing a square of the Rainbow Peep treat at the bottom of a bowl and topping it with a scoop of strawberry ice cream and whipped cream. You can also wrap individual squares in clear cellophane tied with a pastel ribbon for the perfect party favor or “egg hunt” prize.
Storage & Make-Ahead Tips
To keep your Rainbow Peeps Rice Krispie Treats fresh, store them in an airtight container at room temperature. They will stay soft and delicious for up to 3 to 5 days. If you need to make them ahead of time, they are best prepared no more than 24 hours in advance for maximum freshness. We do not recommend refrigerating them, as the cold air can cause the cereal to go soft and the marshmallow to become overly firm. For long-term storage, you can freeze them for up to a month, though the frosting may lose some texture.
FAQs
Can I make these on the stovetop?
Yes! If you prefer the stovetop, melt the butter in a medium saucepan over low heat. Add the Peeps and stir constantly until just melted, then remove from heat immediately to mix in the cereal.
Why are my treats so hard?
Hard treats usually result from two things: overcooking the marshmallows in the microwave or pressing them too firmly into the pan. Use low heat and a gentle touch!
Do I have to use vanilla frosting?
Not at all. You can use cream cheese frosting for a tangier flavor, or skip the frosting entirely if you want a less sweet treat.
Can I use different cereal?
Absolutely. Fruity Pebbles work wonderfully for an even more colorful (and very sweet) treat, or Cheerios for a slightly heartier crunch.
How do I get clean cuts?
For perfectly square edges, let the bars set completely. Use a long, sharp chef’s knife and wipe it clean with a damp cloth or re-grease it with butter between every cut
Rainbow Peeps Rice Krispie Treats are the quintessence of festive baking—simple, joyful, and visually stunning. By taking a few extra minutes to layer the colors, you transform a basic snack into a memorable holiday tradition. Whether they end up in a lunchbox or on a dessert pedestal, these bars bring a smile to everyone’s face. Happy Easter, and enjoy the sugar rush of these beautiful, multi-colored delights!
