The Marshmallow Magic: Understanding Peeps
Before we jump into the microwave phenomenon, it’s essential to understand what Peeps are made of. Peeps are predominantly made of sugar, corn syrup, gelatin, and artificial flavoring and coloring. This combination allows them to maintain their distinct shape and fluffy texture, but it’s also what makes them a spectacular candidate for a microwave experiment.
When exposed to heat, the properties of these ingredients start to change, leading to some unexpected results.
What Happens Inside the Microwave?
The microwave operates on the principle of electromagnetic radiation. It generates microwaves, which create an oscillating electric field that causes polar molecules, mostly water, to move rapidly. This motion generates heat, effectively cooking or heating the food.
When you expose a Peep to microwaves, a fascinating series of events unfolds:
- Heating Up: Initially, the heat begins to increase the temperature of the Peep. As the temperature rises, the sugar molecules begin to dissolve.
- Expansion: As the sugar melts and moisture heats up, the air trapped inside the Peep expands. This expansion is similar to what happens to popcorn kernels when heated, leading to a dramatic increase in size.
- Puffing Up: The Peep can swell to several times its original size, creating a fluffy, cloud-like texture that is mesmerizing to watch.
- Melting and Collapsing: Eventually, as the temperature continues to rise, the structural integrity of the Peep begins to break down. The marshmallow becomes gooey and may even spill over.
Why Do Peeps Expand in the Microwave?
The expansion of Peeps in the microwave can be attributed to several factors:
- Air and Water Content: The air that is trapped in the Peep and any moisture from the gelatin and sugar absorbs heat and expands.
- Glycerin: A common ingredient in marshmallows, glycerin helps maintain the softness of Peeps. When heated, it becomes less viscous, contributing to the Peep’s gooeyness.
- Corn Syrup: When heated, corn syrup melts and contributes to the liquid state that causes the Peep to spill over.

What happens to a Peep when you put it in the microwave?
When you put a Peep in the microwave, the marshmallow inside starts to heat up and expand. This occurs because the moisture within the marshmallow turns into steam, creating pressure that causes the Peep to swell. As the heat increases, you’ll notice that the Peep gains volume, often dramatically so, and can double or even triple in size, creating an entertaining spectacle.
However, the outer sugary coating of the Peep can also become quite sticky and gooey as it melts. If microwaved for too long, the marshmallow might eventually burst, leading to a gooey mess that can coat the microwave’s interior. Therefore, it’s crucial to keep an eye on the Peep while it’s heating to avoid any potential disasters.
Is it safe to microwave Peeps?
Yes, it is generally safe to microwave Peeps, but there are some precautions to consider. When heated, Peeps expand rapidly, and if they are microwaved for too long, they can create a messy explosion. To minimize this risk, it’s recommended to microwave them for short intervals, such as 10-15 seconds, and check for expansion regularly.
It’s also essential to place the Peep on a microwave-safe plate to catch any overflow. Additionally, remember that the surface of the Peep can become extremely hot. Therefore, allow it to cool slightly before handling after microwaving to prevent burns.
How long should I microwave a Peep?
The ideal microwaving time for a Peep can vary depending on the wattage of your microwave and the number of Peeps you’re heating. Generally, starting with 10-15 seconds is a good approach. This short duration allows you to monitor the expansion without risking an explosion or mess.
If you’re interested in creating a larger marshmallow or a fun shape, you can add more time in 5-second increments. Just keep an eye on how much the Peep expands to determine the perfect duration. This method ensures you have control while enjoying the sweet science of microwaving.
What can I do with microwaved Peeps?
Microwaved Peeps can be used in a variety of fun and creative ways.

Can I microwave multiple Peeps at once?
Yes, you can microwave multiple Peeps at once, but be cautious about how many you choose to heat together. If microwaving more than one, ensure that they are spaced out on the plate to allow for even heating and expansion. This helps to minimize the risk of them sticking together or creating unevenly cooked marshmallows.
Just like with a single Peep, keep an eye on the heating process. Multiple Peeps will require slightly more time to heat, but it’s essential to avoid excessive duration to prevent any overflow or mess. Start with a shorter time and check the progress frequently to find the perfect balance for your batch.
Why do Peeps get so sticky when microwaved?
When Peeps are microwaved, the heat causes the sugar in both the marshmallow and the coating to melt. As the marshmallow expands and the sugar begins to liquefy, the texture of the Peep changes and becomes incredibly sticky. This results from the breakdown of the sugar molecules, which lose their crystalline structure and transform into a gooey, viscous liquid.
The stickiness may enhance the fun factor when consuming or decorating with the Peeps, but it also means that you should be prepared for potential mess. To manage stickiness, it can help to let the Peeps cool for a bit before handling them or using gloves to avoid getting your hands sticky.
Are there different varieties of Peeps to microwave?
Yes, Peeps come in a variety of shapes, sizes, and flavors that you can enjoy microwaving. Beyond the classic chick shape typically associated with Easter, there are bunny shapes, holiday-themed designs, and even seasonal flavors like pumpkin spice or chocolate.
