Why you’ll love this green oozy dip

Wow, this Halloween recipe is really as simple as it gets — just mix, color, and serve! It’s sweet, creamy, and perfectly dippable, making it an instant hit at parties. You only need a few ingredients, some of which you probably already have, and you can easily adjust the color to your liking. Matcha gives the dip a fun kind of natural green hue (without tasting overly “green”), or you can use spirulina or good old-fashioned food coloring for a bright, cartoonish pop of color. Whether you’re hosting a Halloween party or looking for a kid-friendly dessert activity, this dip delivers spooky fun in minutes.

Ingredients You’ll Need

You’ll only need a handful of ingredients for this simple dip:

• Cream cheese: Use a full 8-ounce block of softened cream cheese to make your dip smooth and rich.
• Marshmallow cream: A 7-ounce jar of marshmallow fluff gives it that signature sweetness and crazy gooey texture.
• Matcha powder: Just ½ teaspoon adds the enough green color without an overpowering flavor — the marshmallow and cream cheese mask most of that matcha taste.
• Green food coloring or spirulina (optional): If you prefer, you can swap the matcha for food coloring. Spirulina works too, though it gives the whole dip a slightly bluer tone.
• Fruit for dipping: Strawberries are a classic, but apples, grapes, and pineapple would work beautifully.
• Candy eyes (optional): Totally optional, but they take this dip from “what the heck is that green stuff” to “oh that’s a monster dip.”

How to Make Monster Marshmallow Dip

1 Beat the ingredients together: In a mixing bowl, use a hand mixer to blend the softened cream cheese, marshmallow cream, and matcha powder together until the mixture is smooth, creamy, and fluffy.

2 Adjust to taste: If you’re using food coloring, add a few drops at a time until you reach your desired shade of green. Spirulina works too but will lean more blue-green in color.

3 Transfer to a serving bowl: Once everything is smooth and vibrant, spoon the dip into a serving dish.

4 Decorate for fun: Top with candy eyes, gummy worms, or Halloween sprinkles to make it look like bubbling monster slime.

5 Serve and enjoy: Pair with fresh fruit, cookies, pretzels, or anything you love to dip — perfect for parties and spooky movie nights!

Tips for Success

To make sure your green ooze dip turns out perfectly, start with softened cream cheese — it’ll mix more easily with the marshmallow fluff and give you that smooth, airy texture. Matcha adds a nice natural color, but because it can turn bitter if you use too much, stick with a small amount for flavor balance. If you’re not a fan of matcha, food coloring is a foolproof alternative that lets you control the exact shade of green. Spirulina works too, though it tends to be more blue-green in color. And for maximum Halloween flair, don’t skip the decorations! Candy eyes, gummy worms, or even mini marshmallows make it come to life.

Serving & Storage

This dip is best served immediately after mixing, but you can make it up to a day ahead if needed. Just store it in an airtight container in the fridge and give it a quick stir before serving — it may firm up a bit when chilled.

To serve, surround your green ooze with a platter of dippable treats. Strawberries are classic, but sliced apples, grapes, pineapple chunks, or even pretzels all pair perfectly with the sweet, fluffy texture. You can also serve it with graham crackers, cookies, or as part of a Halloween dessert board. If you want to really make an impression, spoon the dip into a small cauldron-style bowl for a fun “witch’s brew” presentation.

Any leftovers can be stored in the fridge for up to three or four days — though we doubt they’ll last that long! Freezing isn’t recommended, as the texture can separate once thawed.
