Edible Peep Playdough

Easter is just around the corner, so this week I’m focusing on fun Easter activities. Today I’ll be focusing on edible peep playdough and slime.

The best thing about this activity, is that it covers all the bases: it’s fun, educational, delicious, easy to make, and pretty to look at!

Ingredients & Instructions


  1. Place peeps into microwave safe bowl and cook for 30-45 seconds.
  2. Remove from microwave and add canola oil and 3/4 cups of corn starch.
  3. Stir until the melted marshmallows can be handled. It’s important to stir until the corn starch is completely mixed in.
  4. Next, dust hands with corn starch and knead until it’s not sticky and easily pliable.
  5. Get creative. Use cookie cutters to make shapes. Challenge your child to make cool structures, letters, or shapes.


  • Almost any oil will work. My two favorites for making this dough are crisco or coconut. Coconut tastes and smells better (in my opinion), but for those who don’t like coconut, crisco makes a great scent free alternative.
  • You can also substitute powdered sugar for cornstarch or make one batch with each and have your children compare/contrast.
  • If you’re child is more interested in making slime, decrease the corn starch. Around 3 tablespoons should give you a great consistency, however, I reccomend measuring out 1 tablespoon at a time until you reach the desired consistency. Make sure each tablespoon is thoroughly mixed in before adding the next.
  • If it’s too sticky, add more cornstarch/powered sugar. If it’s too stiff add more oil.
  • Only store this in a baggie or air tight bowl for around 3 days.
  • Use fresh peeps. Stale peeps don’t provide the same consistency.

Science & Sensory Benefits

Research shows that sensory play builds nerve connections in the brain’s pathways, which lead to the child’s ability to complete more complex learning tasks. Sensory play supports language development, cognitive growth, fine and gross motor skills, problem solving skills, and social interaction.

Playing with playdough in particular helps little hands improve their fine motor skills, helping improve things like writing. It’s also an amazing tactile experience and gives kids a way to feel unique textures.

The STEAM benefits of this activity are also super awesome:

  • Science: How does heating the Peeps change their properties?
    • Peeps are marshmallows, and marshmallows are made of tiny air bubbles surrounded by gelatin and sugar syrup (sugar). When the peeps are microwaved, the water molecules in that syrup begin to vibrate and heat up. This process creates steam, and it fills all of the air pockets in the peeps. As the air pockets fill up the peeps expand!
  • Technology: What tools do you use to change Peeps into play dough?
  • Engineering: What recipe is required to transform Peeps into play dough?
  • Art: Which colors are the peeps? What colors can you make mixing them? What shapes can you make?
  • Math: How much corn starch is needed to turn Peeps into playdough? How long do the marshmallows have to be heated? What happens if you cook them too long or too little?
