- Step 3: Pour the coffee mixture into dessert cups or a glass dish.

- Add a splash of sweetened condensed milk along with the cream for a richer taste.
- Use whipped cream instead of thickened cream for a lighter, airier topping.

FAQs
Can I use regular coffee instead of instant coffee?
Instant coffee is best for dissolving fully into the jelly mixture. If you prefer, you can use strong brewed coffee, but you’ll need to adjust the gelatin amount and sweetness to keep the texture and flavor balanced.
Can this dessert be made vegan or dairy-free?
Yes, you can substitute gelatin with agar-agar for a vegan option and use plant-based cream alternatives like coconut cream for the topping.
