If you've ever scrolled through slime TikTok (and honestly, who hasn't?), you've probably seen those impossibly smooth, spreadable slimes that look like actual butter. Good news — butter slime is one of the easiest and most satisfying slimes to make at home, and we're about to show you exactly how to nail it first time.
Butter slime gets its name from its incredibly soft, spreadable texture. It holds its shape beautifully, stretches without breaking, and has that matte, clay-like finish that makes it absolutely mesmerising to play with. Whether you're a total beginner or a seasoned slime maker, this is one recipe you'll come back to again and again.
Let's get into it.
What Is Butter Slime?
Butter slime is a type of slime that uses clay (usually Model Magic or a similar soft modelling clay) to create a thick, smooth, buttery texture. Unlike regular slime, which can be stretchy and sometimes a bit stringy, butter slime is dense, spreadable, and holds its shape when you press into it.
Think of it like this: if regular slime is the fun, bouncy friend, butter slime is the cool, calm, collected one. It's incredibly satisfying to poke, flatten, and spread — which is exactly why it's one of the most popular slime types on social media right now.
The secret to great butter slime? Getting the ratio of clay to slime base just right, and using a proper slime activator like the Bezzie Slime Activator to get that perfect consistency without any guesswork.
What You Need to Make Butter Slime
Here's your full ingredients list. Don't worry — nothing here is hard to find.
Ingredients
- 120ml PVA white glue (regular white school glue works brilliantly)
- Bezzie Slime Activator — our all-in-one activator that replaces borax, contact lens solution, and all those fiddly alternatives Shop here
- Model Magic clay (or any soft, air-dry modelling clay) — about one small packet (roughly 25–30g)
- Lotion or baby oil (optional, for extra softness)
- Food colouring or paint (optional, for colour)
- Fragrance oil (optional, because who doesn't love a slime that smells amazing?)
Tools
- A medium mixing bowl
- A spoon or spatula for stirring
- A flat surface for kneading
That's it. No complicated chemistry set required.
How to Make Butter Slime — Step by Step
Follow these steps carefully and you'll have picture-perfect butter slime in about 10 minutes.
Step 1 — Make Your Slime Base
Pour 120ml of PVA white glue into your mixing bowl. If you want to add colour, mix in a few drops of food colouring or a tiny squirt of acrylic paint now. Stir until the colour is evenly distributed.
Top tip: White glue gives you that classic matte butter slime look. If you use clear glue, you'll end up with a slightly different texture — still good, but not quite the same buttery finish.
Step 2 — Add Bezzie Slime Activator
Here's where the magic happens. Add Bezzie Slime Activator to your glue mixture a little bit at a time — start with about one teaspoon. Stir well after each addition.
You'll notice the slime starts pulling away from the sides of the bowl almost immediately. Keep adding activator in small amounts and stirring until the slime forms a ball and stops sticking to the bowl.
Important: Go slowly here. You can always add more activator, but you can't take it out. Adding too much too quickly is the number one mistake people make, and it'll leave you with stiff, rubbery slime instead of that lovely soft texture we're after.

Step 3 — Knead the Slime
Once the slime has come together in the bowl, tip it out onto a clean, flat surface and knead it with your hands for 2–3 minutes. It should feel smooth, stretchy, and slightly sticky — but not so sticky that it clings to your fingers.
If it's still a bit tacky, add the tiniest drop more activator and knead again.
Step 4 — Add the Clay
Now for the bit that turns ordinary slime into butter slime. Take your Model Magic clay, break it into small pieces, and start working it into the slime by folding and kneading.
Keep kneading until the clay is fully incorporated and you can't see any white streaks (unless your slime is white, obviously). This usually takes about 3–5 minutes.
The clay is what gives butter slime that gorgeous thick, spreadable texture. You should be able to feel the difference almost immediately — it goes from stretchy and bouncy to smooth and dense.
Step 5 — Add Extras (Optional)
Want your butter slime to be even softer? Work in a tiny pump of lotion or a few drops of baby oil. This makes it feel absolutely luxurious.
You can also add fragrance oils at this stage. A few drops of vanilla, strawberry, or bubblegum scent takes the whole experience up a notch.
Step 6 — Play and Enjoy!
That's it — you've made butter slime! Spend a few more minutes kneading to make sure everything is perfectly blended, and then get stuck in (not literally).
Spread it, poke it, slice it with a butter knife for those satisfying ASMR videos. Butter slime is brilliant for filming because it holds its shape so well.
Tips for the Perfect Butter Slime
We've been making slime for years, and here are our top insider tips:
- Use fresh clay. If your Model Magic has been sitting open for a while and feels dry or crumbly, it won't blend properly. Fresh, soft clay is a must.
- Go easy on the activator. We can't stress this enough. Butter slime needs to be soft to feel right, and over-activating is the fastest way to ruin that.
- Add lotion if it feels stiff. A little bit of lotion or baby oil can rescue butter slime that's gone slightly too firm.
- Store it in an airtight container. Butter slime dries out faster than regular slime because of the clay. Keep it sealed when you're not playing with it.
- Warm it up before playing. If your butter slime has been sitting in its container for a while, give it a good knead to warm it up and soften the texture.
Troubleshooting Your Butter Slime
My butter slime is too sticky
You need a touch more activator. Add it drop by drop and knead after each addition. Don't dump it in all at once.
My butter slime is too stiff and rubbery
You've added too much activator. Work in some lotion, baby oil, or a small amount of warm water to soften it back up. Give it a really good knead — sometimes it just needs time and warmth from your hands.
The clay won't mix in properly
Your clay might be too dry, or you might not be kneading long enough. Try breaking the clay into even smaller pieces and kneading more vigorously. If it still won't blend, try a different brand of clay.
My butter slime dried out overnight
Next time, store it in a sealed container or zip-lock bag. To revive dried-out butter slime, add a few drops of warm water and a pump of lotion, then knead thoroughly.

Frequently Asked Questions
What clay is best for butter slime?
Model Magic by Crayola is the most popular choice and the one we recommend. It's soft, blends easily into slime, and gives that classic buttery texture. Some people also use Daiso clay, which works well but gives a slightly different feel. Avoid using hard modelling clay or Play-Doh — they won't break down properly and will leave your slime lumpy.
Can I make butter slime without clay?
Technically, butter slime needs clay to achieve that signature thick, spreadable texture. Without clay, you'll end up with regular slime. However, some people use cornflour as a substitute — it gives a slightly similar effect, but the texture isn't quite as smooth or long-lasting as proper clay-based butter slime.
How long does butter slime last?
If stored properly in an airtight container, butter slime can last 2–4 weeks. The clay component means it dries out a bit faster than regular slime, so always seal it up after playing. If it starts to dry, a few drops of lotion and a good knead can bring it back to life.
Is butter slime safe for young children?
Butter slime made with PVA glue and Bezzie Slime Activator is non-toxic, making it suitable for children. However, we always recommend adult supervision for children under 6, and slime should never be eaten. For more on slime safety, check out our guide: Is Slime Safe for Kids?.
Can I add glitter or beads to butter slime?
Absolutely! Glitter, foam beads, and small charms all work brilliantly in butter slime. Add them after you've mixed in the clay, and knead until they're evenly distributed. Just keep in mind that adding too many mix-ins can change the texture slightly.
