Combine sweetened condensed milk and chopped butter in a saucepan over low heat. Stir gently until melted and smooth, creating a rich base for your crackles.

Melt in the white chocolate (remember to reserve some for coating). Continue stirring until fully melted and velvety, ensuring no lumps remain.

Mix in a large bowl puffed rice cereal, desiccated coconut, chopped raspberry lollies, and chopped pistachios. This colorful combination will bring delightful textures to your treats.

Pour the melted chocolate mixture over the dry ingredients. Stir well until everything is evenly coated, bringing the festive flavors together beautifully.

Press the mixture firmly into a lined muffin pan, ensuring each cup is packed tightly. This helps the crackles hold their shape once set.

Chill the pan in the refrigerator for at least 2 hours or until set. This step is crucial for achieving that satisfying firmness.

Remove the crackles from the pan once set, and coat them with the reserved melted white chocolate for extra indulgence. Drizzle or fully coat, it's up to you!

Decorate with finely chopped red raspberry lollies and pistachios if desired. This adds a festive touch that tantalizes the eyes as well as the taste buds.
