What are watermelon gelatin cubes?
These are chilled, layered squares made by setting fruit juice and creamy mixtures with gelatine. The recipe combines watermelon with yoghurt and a condensed milk mixture for contrasting colours and flavours.
Layered gelatine desserts are made in many styles, and this version works by letting each layer set before adding the next. The method provided does not specify how long to chill the final layer.

Watermelon juice and sugar provide most of the carbohydrates, while the yoghurt and condensed milk contribute protein and fat. Serve a cube alongside fresh fruit, or pair it with a meal that includes a savoury protein source.
The watermelon layer
Juice: fresh watermelon juice gives the base its fruit flavour, while lemon juice adds a bright note.
Sugar: stir the mixture until the sugar dissolves before adding the melted gelatine, so the layer sets evenly.
Getting neat layers
First layer: allow it to set fully before pouring on the yoghurt mixture, or the layers may blend together.
Second layer: cool the yoghurt mixture before adding it gently. Pouring a hot mixture over the set base can soften it.
Working with gelatine
Blooming: the recipe rests each portion of gelatine in cold water for 10 minutes before melting it over a hot water bath.
Melting: stir the melted gelatine into the warm mixture off the heat. Avoid letting the gelatine mixture boil.
Texture and setting
A fully set first layer should feel firm before the next mixture goes on. The recipe gives about 4 hours for this layer and at least 4 hours for the yoghurt layer.
The final layer's chilling time is not included in the method. Check that it has set before cutting, allowing additional refrigeration time if needed.
Cutting and serving
Use a square tin as directed and cut the dessert into cubes once all layers are firm. A clean, warm knife can help make tidier cuts; wipe it between slices.
Serve the cubes chilled. Their fruity and creamy layers pair well with fresh fruit or a simple summer meal.
Recipe notes & tips
- Measure each gelatine portion separately before starting.
- Let each layer set before adding the next one.
- Pour the yoghurt mixture gently to keep the base intact.
- Make sure the melted gelatine is fully stirred through each mixture.
- Use a sharp knife and wipe it clean between cuts.
Variations
- Citrus twist: Replace the lemon juice with lime juice for a different bright note.
- Fruit garnish: Serve the cubes with pieces of fresh watermelon.
- Vanilla yoghurt: Use a vanilla-flavoured Greek yoghurt and adjust the added vanilla to taste.
- Individual portions: Set the layers in small serving glasses instead of a square tin.
- Mixed melon: Replace some of the watermelon juice with another fresh melon juice.
Common mistakes to avoid
- Adding the next layer too soon: Wait until the layer beneath is set so the colours stay distinct.
- Pouring while too hot: Cool the yoghurt mixture before layering to avoid softening the base.
- Skipping the bloom: Rest the gelatine in cold water for the stated 10 minutes before melting.
- Boiling the gelatine: Melt it over a hot water bath and stir it into the mixture off the heat.
- Cutting too early: Make sure the layers are firm before slicing into cubes.
How to store
Keep the cubes covered in the fridge and serve chilled. The recipe does not specify a storage duration; avoid leaving the gelatine dessert at room temperature for extended periods.
Frequently asked questions
How long does this recipe take?
The stated total time is 275 minutes. The method includes about 4 hours for the first layer and at least 4 hours for the yoghurt layer, so check the timing against your preparation schedule.
Can I make the cubes ahead?
Yes. The layers need several hours to set, so you can prepare them in advance and keep the finished dessert covered in the fridge.
When should I pour on the yoghurt layer?
Wait until the watermelon layer is fully set. Cool the yoghurt mixture before pouring it gently over the base.
How do I know when a layer is set?
It should feel firm rather than liquid when the tin is gently moved. Follow the recipe's timings as a guide, but allow more chilling time if it has not set.
How should I cut the cubes neatly?
Cut the chilled dessert with a sharp knife, wiping the blade clean between slices. A briefly warmed knife can also help make clean cuts.
Does the method say how long to chill the last layer?
No, the supplied method ends after the melted gelatine is stirred into the condensed milk mixture. Refrigerate until the final layer is set before cutting.
