How to Make Halloween Slime Pudding Cups

This recipe is incredibly simple to make—no baking, no cooking, and no fancy tools required.

Step 1: Make the Slime Pudding

1. In a large mixing bowl, combine the instant pudding mix with the cold milk.

2. Whisk for 2–3 minutes until thickened.

3. Add green food coloring a few drops at a time until you reach your desired slimy shade. The brighter and grosser-looking, the better!

4. For extra flavor, add a few drops of vanilla or mint extract (optional).

5. Set the pudding aside for 5 minutes to firm up.

Step 2: Crush the Cookies

1. Place chocolate sandwich cookies in a food processor and pulse until you have fine, dirt-like crumbs.

2. Alternatively, place the cookies in a zip-top bag and crush with a rolling pin.

Tip: Leave a few chunkier bits for texture—worms like lumpy dirt!

Step 3: Assemble the Pudding Cups

1. Spoon or pipe the green pudding into clear cups, filling each about ¾ full.

2. Add a layer of crushed cookie dirt on top of each pudding cup.

3. Press a few gummy worms into the cookie layer, letting them stick out like they’re crawling through the slime.

4. Add sprinkles, candy eyes, or Halloween toppers for extra flair.

Step 4: Chill and Serve

1. Refrigerate the pudding cups for at least 30 minutes before serving.

2. If making ahead, add gummy worms just before serving so they stay chewy and fresh.

Variations and Creative Twists

There are tons of ways to personalize your slime pudding cups for different tastes or dietary needs:

Swamp Slime Version

Add a layer of green jelly (gelatin or agar) beneath the pudding to mimic a swampy slime effect. This gives a fun two-tone look and an extra squishy texture.

Graveyard Pudding Cups

Stick a cookie “gravestone” (like a Milano or rectangular biscuit) into the dirt topping and use icing to write “RIP.” Add candy bones for a mini edible cemetery.

Monster Slime Cups

Top each pudding cup with googly candy eyes, marshmallow monsters, or mini eyeball candies for a creature-themed treat.

Vegan/Dairy-Free Pudding Cups

Use a dairy-free pudding mix (or homemade from plant-based milk and cornstarch) and vegan sandwich cookies. Plenty of vegan gummy worms are available—just check the label for gelatin-free versions.

Gluten-Free Option

Swap the regular sandwich cookies for a certified gluten-free version, and double-check your candy ingredients.

Tips for the Best Slime Pudding Cups

• Use clear cups – The green slime and dirt layers are more effective when they’re visible.

• Chill before serving – Let the pudding set for the best texture.

• Use piping bags for clean layering – Spoon or pipe pudding into cups for a mess-free look.

• Color with care – Gel food coloring gives a more vibrant slime green with less liquid.

• Add candy just before serving – Gummy worms can get soggy if left overnight in the fridge.

How to Serve Slime Pudding Cups

These are incredibly versatile and can be served in several creative ways:

• Individual party cups – Great for grab-and-go Halloween parties or potlucks.

• Mini plastic cauldrons – For a witchy look!

• Mason jars – Ideal for layered presentation and making ahead.

• Cupcake liners or silicone molds – For smaller kid-friendly portions.

Pair them with Halloween napkins, monster spoons, or serve on a spooky black tray with spider webs for the full effect.

Make-Ahead and Storage Tips

• Make up to 24 hours in advance – Store covered in the fridge.

• Don’t add gummy worms too early – They can harden or lose texture if left overnight in pudding.

• Leftovers – Can be stored in the fridge for 2–3 days, though the cookie topping may soften.

Avoid freezing pudding cups as the texture will not hold up well once thawed.
