Notes & Substitutions

Feel free to experiment with your favorite flavors! You can use any sugar-free jelly crystals, such as raspberry, orange, or blackcurrant, to change the taste profile. For gelatine, ensure you use powdered sachets as they are easiest to dissolve and set consistently. While fat-free natural yogurt provides the creamy layer and keeps the Syn value low, you could try a dairy-free alternative if needed, ensuring it’s also low in fat and sugar. Consider almond or lemon extract instead of vanilla for a different aromatic twist in your homemade jelly sweets.

How To Make Slimming World Jelly Sweets

Follow these simple steps to create your very own batch of delicious Slimming World jelly sweets. Precision and patience are key for the perfect texture!

  1. Prepare the Jelly and Gelatine Mixture: First, combine both sachets of sugar-free jelly crystals and both sachets of powdered gelatine in a large measuring jug. Carefully add 280ml of boiling water to the jug. Stir the mixture continuously with a whisk or spoon until both the jelly crystals and gelatine are completely dissolved. Ensure there are no lumps remaining for a smooth consistency.
  2. Cool the Mixture: It’s crucial to let this hot mixture cool down entirely before proceeding. This step helps prevent the yogurt layer from separating or melting when added. Allow it to sit at room temperature until it reaches a lukewarm or slightly cooler state.
  3. Pour the First Layer: Once cooled, carefully pour exactly half of the jelly and gelatine mixture into your chosen ice cube moulds. Fill each cavity about halfway. This will form the clear, vibrant bottom layer of your Slimming World jelly sweets.
  4. Chill Initial Layer: Place the moulds with the first layer into the refrigerator. Chill them for approximately 15 minutes. This brief chilling period allows the first layer to partially set, creating a stable base for the creamy second layer. It should be firm enough to gently touch without being fully solid.
  5. Combine Remaining Mixture with Yogurt and Vanilla: While the first layer chills, take the remaining jelly and gelatine mixture. Add the 170g of fat-free natural yogurt and ½ teaspoon of vanilla extract to it. Whisk thoroughly until all ingredients are well combined and the mixture is smooth and creamy.
  6. Pour Second Layer: Retrieve the moulds from the fridge. Carefully pour the yogurt-infused mixture over the partially set first layer in each cavity. Fill the moulds completely to the top. The slightly firm first layer will prevent the two layers from mixing too much.
  7. Chill Until Fully Set: Return the moulds to the refrigerator. Allow them to chill undisturbed until the Slimming World jelly sweets are completely firm and set. This typically takes about 2 hours, but it may vary depending on your fridge and mould size.
  8. Carefully Remove from Moulds: Once fully set, gently demould the jelly sweets. Silicone moulds work best for this, allowing you to pop them out easily without damage. If using rigid moulds, you might need to briefly dip the bottom in warm water.

Pro Tips & Troubleshooting

To achieve the best results with your Slimming World jelly sweets, keep these tips in mind. For perfect setting consistency, ensure your boiling water is hot enough to fully dissolve the gelatine, but let the mixture cool completely before adding yogurt. This prevents separation. If your sweets are sticking, silicone moulds are your best friend; otherwise, lightly grease rigid moulds with a tiny amount of low-calorie cooking spray.

To ensure layers bond properly, make sure the first layer is firm but still slightly tacky, not fully solid, when you add the second. Adjust sweetness by adding a few drops of sugar-free sweetener to the yogurt layer if you prefer a sweeter treat. If your sweets aren’t setting, you might have used too much liquid or not enough gelatine, or the mixture wasn’t chilled long enough.

Serving, Storage & Variations

These delicious homemade treats are perfect for satisfying cravings!

Flavor Variations

Get creative with your Slimming World jelly sweets by mixing different sugar-free fruit jelly combinations. Try a vibrant orange and lemon mix, or a dark berry blend. You can also add sugar-free flavorings like cheesecake or chocolate drops to the yogurt layer for an extra dimension. For a natural touch, blend a small amount of sugar-free fruit purée (like raspberry or mango) into the yogurt mixture before adding.

Shape & Size Ideas

Silicone moulds come in countless fun designs, from stars and hearts to mini animal shapes. If you don’t have individual moulds, you can pour the mixture into a shallow, lined tray and then cut it into squares, diamonds, or use mini cookie cutters for charming shapes once set. This allows for diverse portion sizes, from bite-sized nibbles to larger squares.

Storage Tips

Always store your Slimming World jelly sweets in an airtight container in the refrigerator. This keeps them fresh and prevents them from drying out or absorbing fridge odors. They will stay fresh and delicious for up to 3-4 days. While technically freezable, the texture might change slightly upon thawing, becoming a bit softer. It’s generally best to enjoy them fresh from the fridge.

Frequently Asked Questions (FAQ)

Are these completely Syn-free?

No, these Slimming World jelly sweets are ½ Syn per serving (4 sweets) due to the gelatine.

Can I use liquid gelatine?

It’s best to stick to powdered gelatine for this recipe as it gives a more consistent set. Liquid gelatine can have different setting properties.

How long do they last?

When stored in an airtight container in the fridge, they will stay fresh for 3-4 days.

Can I use different types of yogurt?

Yes, but ensure it’s fat-free and plain to keep the Syn value low and avoid unwanted sugars. Flavored yogurts often contain added sugar.

Can I add fresh fruit?

While tempting, fresh fruit can sometimes prevent gelatine from setting properly due to certain enzymes. If you wish to add fruit, cook it first to break down these enzymes.

Why aren’t my sweets setting?

This usually happens if the gelatine wasn’t fully dissolved, or if there wasn’t enough chilling time. Ensure water is boiling and give them ample fridge time.
