Supplies to Make Chocolate Birthday Slime
Here’s what you’ll need for each batch of DIY slime.
- White glue: for the base of the slime.
- Shaving cream: creates fluffiness.
- Foaming hand wash: adds extra volume.
- Baking soda: works as an activator.
- Contact lens solution: for that perfect slime texture (not too sticky!)
- Foam beads: used to mimic sprinkles.
- Chocolate-scented fragrance: for the delicious smell.
- Brown acrylic paint: for the chocolate color
- A small bowl and something to stir it with: plastic spoons or popsicle sticks work well.

How to Make Birthday Cake Slime
1. Combine: Mix white glue and shaving cream in a bowl. The amount of shaving cream doesn’t have to be exact, so don’t stress about precise measurements here.


2. Add volume: Pour in some foaming hand wash and mix until it gets super fluffy and light. You’ll notice it starts to look airy, like whipped cream.

3. Color it: Mix in your brown acrylic paint until the mixture resembles the color of chocolate frosting. Start with a little, and add more as needed to get the color just right.

4. Get stretchier: Stir in cornstarch (or a pinch of body lotion) to help the slime stretch better. Both of these make the texture better for squishing and pulling.

5. Add beads: Pour in a small amount of the multi-colored foam beads. You don’t need a lot, as these are just meant to be the sprinkles.
6. Add scent: Add a few drops of chocolate fragrance oil. This is what will make your slime smell just like a yummy chocolate cake. While the slime smells great, make sure it is not tasted!

7. Activate it: Slowly mix in your contact lens solution one spoonful at a time. Keep stirring until the slime pulls away from the bowl.

8. Knead: Once it’s mixed, take it out and knead it with your hands. This part takes a few minutes, but soon you’ll have a stretchy, non-sticky slime.

Benefits of Making Slime
- Hands-on bonding: It’s an activity you can enjoy with your child.
- Sensory learning: Kids use multiple senses while stretching, squeezing, and adding textures.
- Encourages creativity: Making slime lets kids experiment with color, scent, and texture combinations.
