Instructions
- Preheat your oven to 350°F (175°C).
- In a mixing bowl, combine gluten-free chocolate cookie crumbs, melted butter, and sugar. Press this mixture firmly into a tart pan to form the crust. Bake for 8–10 minutes, then allow to cool.
- In a saucepan, whisk together the coconut cream, sugar, and cornstarch over medium heat until it begins to thicken slightly.
- Stir in the white chocolate chips, mixing until they melt completely and the mixture is smooth.
- Add the vanilla extract and green food coloring. Whisk until you achieve a creamy, slime-like consistency.
- Pour the filling into the cooled crust, smoothing the top with a spatula.
- Chill the tart in the refrigerator for at least 2–3 hours, or until the filling is firm.
- Before serving, sprinkle crushed chocolate cookies on top and decorate with candy eyeballs or gummy worms for a creepy effect.

You Must Know
- Ensure your coconut cream is thoroughly chilled for a thicker filling.
- Adjust the green coloring to your desired shade for the ultimate slime effect.
- Use gluten-free and dairy-free ingredients to accommodate dietary preferences.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. The tart can also be frozen for up to a month, but decorations should be added fresh before serving.
Ingredient Substitutions
For a vegan version, opt for dairy-free white chocolate chips and vegan butter. If you prefer a natural green color, use matcha or spirulina powder instead of artificial food coloring. If coconut cream is unavailable, heavy cream can be used, but note it won’t be vegan.
Serving Suggestions
Serve this tart chilled, straight from the fridge, for the best texture. Pair it with a scoop of dairy-free vanilla ice cream or a dollop of whipped coconut cream to complement its rich flavors.
Cultural Inspiration
This recipe draws inspiration from American Halloween traditions, where playful, spooky treats are a must-have. The concept of “slime” ties into the fun and slightly eerie theme, making it a delightful addition to Halloween parties. The use of green coloring and quirky decorations embodies the playful spirit of the holiday.
Pro Tips
- For a firmer crust, ensure you press the cookie mixture evenly and compactly in the tart pan.
- When cooking the filling, stir constantly to prevent clumps and ensure a smooth texture.
- If the filling is too thick, add a splash more coconut cream until the desired consistency is reached.
