ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

• Plain or unflavoured gelatin powder (or vegetarian alternative)

• Granulated sugar

• Water

• Food colouring (a variety of colours such as red, yellow, green, blue, purple)

• Flavoured jelly mixes (optional, to enhance taste)

• Sweetened condensed milk or evaporated milk mixed with sugar (for creamy layers)

• Heavy cream or whipping cream (optional, for a richer creamy layer)

• Vanilla extract or other mild flavourings (such as coconut or almond)

• A pinch of salt (to balance sweetness)

directions

1. Prepare the Creamy Layer Mix
   In a bowl, mix condensed milk (or mixture of evaporated milk and sugar), heavy cream, vanilla extract, and a pinch of salt. Stir until smooth and refrigerate while preparing the jelly layers.

2. Bloom the Gelatin
   For each jelly colour, bloom the gelatin in cold water according to the package instructions. Let it sit until fully absorbed.

3. Create Jelly Layers
   For each colour:
   a. Heat water and sugar until sugar dissolves; add the bloomed gelatin and stir until fully dissolved.
   b. Add food colouring and any flavouring. Let it cool slightly (but not set).

4. Layering Process
   a. Pour the first jelly layer into a mould or cake pan. Let it set in the refrigerator until firm (about 15‑20 minutes).
   b. Gently pour a thin layer of the creamy mixture over the set jelly; chill until this layer is set.
   c. Repeat with the next jelly colour, then creamy layer, alternating until all colours and cream layers are used.

5. Final Chill
   Once all layers are assembled, chill the cake for several hours or ideally overnight to allow all layers to firm completely and for flavours to meld.

6. Unmould and Serve
   To unmould, dip the base of the mould briefly in warm water to loosen edges, then invert onto a serving plate. Slice with a sharp knife dipped in hot water for clean cuts.

Servings and timing

• Servings: about 8–10 slices (depending on mould size)

• Active preparation time: approximately 45 minutes

• Chilling / setting time: at least 4 hours; overnight recommended for best texture

Variations

• Use fruit‑flavoured jellies (e.g., orange, strawberry, lime) for more fruity taste.

• Substitute dairy cream with coconut cream for a dairy‑free, tropical twist.

• Incorporate layers of fresh fruit between jelly or cream layers (e.g., sliced strawberries, kiwifruit).

• Use edible glitter or shimmering food colouring to accentuate the prism effect.

• Make a mini version in individual glasses or jars for single servings or party favors.

storage/reheating

• Storage: Keep the cake refrigerated in an airtight container. It will stay good for up to 3 days.

• Avoid freezing, as the texture of jelly and creamy layers may degrade.

• Reheating is not applicable; serve chilled or slightly cool. If it becomes too firm, you may let it sit at room temperature for 10‑15 minutes before serving to soften slightly.

FAQs

What type of gelatin should I use?

You may use powdered gelatin or leaf gelatin. For vegetarian versions, agar‑agar or other plant‑based setting agents can substitute, though setting times may vary.

Can I use ready‑made jelly mixes instead of making jelly from scratch?

Yes, ready‑made jelly mixes work. Just prepare them according to package directions and allow them to cool slightly before layering.

How do I prevent jelly layers from mixing with creamy layers?

Ensure each layer is fully set (firm) before pouring the next. Also, pour the next layer gently, and let the liquid cool slightly so it does not melt or disturb the previous layer.

How many colours can I use?

As many as you like, depending on the depth of your mould. Five to seven layers (alternating jelly and cream) often give a pleasing prism effect without the cake becoming too tall or difficult to set.

What mould should I use?

A loaf pan, springform pan, or removable‑bottom mould works well. Clear glass moulds allow you to see the layers from the side.

Can I make this in advance?

Yes. It’s ideal to make the Prism Jelly Cake the day before serving so that all layers are fully set and flavours have had time to meld.

Is this dessert suitable for children?

Absolutely. Adjust sweetness to taste, avoid strong alcoholic flavourings, and use food‑safe colouring. Be mindful of allergies (gelatin source, dairy, etc.).

Can I make it without dairy?

Yes. Substitute the creamy layers with coconut milk or cream, almond milk mixes, or other non‑dairy creamy substitutes. Test setting, as non‑dairy creams may have a softer texture.

Why did my creamy layer become grainy or split?

This may happen if the creamy mixture was too warm when poured, or if layers are disturbed. It helps if creamy mixture is cool (but still pourable) and gently poured.

How do I cut clean slices?

Use a sharp knife dipped in very hot water, wipe clean between cuts. Cooling cake much firm helps with clean slicing.
