Making black slime can be messy, stain your hands or table, and still result in a grayish slime rather than pure black. Our recipe for Black Butter Slime turns out a velvety smooth fluffy slime with a jet black color.

Black Butter Slime Recipe

Black slime is awesome for so many different sensory play experiences. You can draw on it with chalk markers, use it as a base for a themed slime (like our Queen of Hearts slime or a Halloween slime), etc.

Previously, whenever we made black slime, we’d just use acrylic paint to dye the slime.

It worked okay, but I still found the color wasn’t as jet black as we’d like and I had to really scrub my fingernails after kneading the paint into the slime to get rid of the gray hue.

There is black glitter glue that works, but if you want a pure black slime (without the glitter), I have not found a good brand of black glue that works well for slime.

The best option? Black butter slime.

By using black clay to dye the slime, you get a pure, jet black color, without dying your hands or the surfaces your child is playing on.

This slime has an amazing, squishy, stretchy texture that is somewhere in between slime and play dough. It can mold into different shapes easily and has a great, natural resistance that makes it so much more satisfying to squeeze. The texture also makes the slime less drippy and messy, which is always a win in my books!

You can then add whatever mix-ins or knead in other colors of slime to make a fun themed slime that really pops against the black. We used our black butter slime to make a fun galaxy slime.

What kind of clay do you use for butter slime? While there are a few people who are adamant you need to use Model Magic clay for butter slime, I actually liked the texture (and repeat use) of using a regular modelling clay. The model magic butter slime was fluffier and had a thick texture with awesome resistance, while the modelling clay butter slime was smoother and while thick it could be squished a lot more.
