It’s also a hands-on activity where the end result provides safe and kid-friendly entertainment. Perfect for a rainy day, can enjoy participating in a science activity that results in lots of fun sensory play.
Here are nine of our favorite natural and non-toxic easy slime recipes:
Edible Slime Recipes
1. Edible Slime from Starburst Candy
- 1 bag of Starburst candy
- Powdered Sugar
From the Teach Beside Me blog:
- Gather materials. You will want a couple of small glass bowls and a pot of water to cook on the stove (or a microwave). Divide the Starburst candies by color and unwrap. Place each color into a small glass bowl.
- Mix ¼ c. powdered sugar with ¼ c. cornstarch.
- Boil a pot of water and place the glass bowl into the pot to melt the Starburst candies. (Making it like a double boiler). Stir regularly to prevent burning. Once melted, remove from heat. You can also do it in the microwave for 2 – 30 second increments, stirring in between.
- Turn onto a surface dusted with the cornstarch and powdered sugar mixture. Wait about five minutes until cooled. It can burn you at this point, so REALLY be careful!
- Knead the melted candy with the powdered sugar mixture. Be sure to pull it and stretch it as you knead to let a lot of air into it. This will help it to be less sticky and more stretchy.
2. Edible Marshmallow Slime
- 1 Bag of Mini Marshmallows
- 1/4- 1/3 c. Coconut Oil or any vegetable oil -add more to make it less sticky
- 1/2 c. Powdered Sugar
- Rainbow Sprinkles or Edible Glitter Stars– optional but fun! We added 1-2 Tbsp.
From the Teach Beside Me blog:
- Pour the whole bag of marshmallows into a large microwave safe bowl. Microwave for 30 seconds and stop. Then repeat. Two times was enough for our marshmallows to be entirely melted.
- Add in the powdered sugar and 1/4 c. of oil. Mix well.
- Let it cool for about 15 minutes. Coat your hands in some of the remaining oil and mix by hand. It will be really sticky, but you can continue adding a little oil until it can be held and played with without sticking entirely.
- Mix in 2-3 Tablespoons of rainbow sprinkles.
3. Edible Chocolate Slime
This slime takes on a more playdough texture, which makes it less sticky and clean-up is a breeze.
- ½ cup cornstarch
- 1 Tablespoon cocoa powder
- ⅓ cup coconut milk
From The Soccer Mom Blog:
- Add heaping 1/2 cup of cornstarch and 1 tablespoon cocoa powder to a medium mixing bowl. Whisk together until well combined and you have a light brown powder.
- Heat 1/3 cup coconut milk in microwave until warm (not steaming or boiling). This should take about 20 seconds. Make sure to use a microwave-safe bowl and handle with care.
- Pour warm coconut milk into mixing bowl with cornstarch and cocoa powder. Milk together with a spoon until a smooth slime begins to form.
- You’ll be able to easily scoop the putty out of the bowl by hand when you’re done mixing.
4. Valentine Slime
You can change up the colors to make this perfect for any holiday, but we love the sweet conversation heart accessories.
- 1 Tablespoon Cornstarch
- 14 ounce Can of Sweetened Condensed Milk

Two-Ingredient Slime Recipes
1. Orange Slime
- Psyllium husk powder (Metamucil)
- Americolor Soft Gel Paste Food Color (optional)
From the Fun Littles blog:
- In a really large microwave-safe bowl add 1 tablespoon of fiber supplement. Add your favorite food color and then mix in 1 cup of water. Give it a good whisk and place it in the microwave for about 5 minutes. But do not walk away. The supplement will rise up so it is very important to use a large bowl so that the concoction does not bubble up and spillover. Check after 3 minutes, if it bubbles over, pause the microwave and then restart it. After 5 minutes, it will be like a snakeskin.
2. Glue Stick Slime
