Edible Slime Recipes

1. Edible Slime from Starburst Candy

Materials:

  • 1 bag of Starburst candy
  • Powdered Sugar
  • Cornstarch

Directions:

From the Teach Beside Me blog:

  1. 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.
  2. Mix ¼ c. powdered sugar with ¼ c. cornstarch.
  3. 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.
  4. 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!
  5. 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

Materials:

  • 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.

Directions:

From the Teach Beside Me blog:

  1. 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.
  2. Add in the powdered sugar and 1/4 c. of oil. Mix well.
  3. 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.
  4. 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.

  3. Pour warm coconut milk into mixing bowl with cornstarch and cocoa powder. Milk together with a spoon until a smooth slime begins to form.
  4. You’ll be able to easily scoop the putty out of the bowl by hand when you’re done mixing.
