In a heavy bottom pan take 1.5 cups of milk and let it cook for few mins till it's half the quantity.

Add sugar (as per your taste as white chocolate is also sweet) and let it cook for 2-3 minutes.

Next add kesar milk along with chopped mixed nuts, stir well and let it cook for another minute.

Once done switch off the flame and let the rabdi cool down.

The rabdi should be thick as it will be added as a filling in the chocolate bars.

On the other hand melt 250 grams of white chocolate in microwave for 30 seconds.

Stir well and microwave for another 30 seconds till the chocolate is smooth and melted nicely.

Now for the moulding part: Clean your chocolate moulds with a help of clean and dry cotton.

Pour a thin layer of melted white chocolate in the chocolate bar moulds, cover the sides as well and turn & remove excess of the chocolate.

Keep the chocolate mould in fridge for 5 minutes so the outer layer sets nicely.

Now add the prepared rabdi in a piping bag so it's easy to fill the rabdi in the moulds.

Fill the moulds till half with rabdi.

Now pour the melted white chocolate from top till the size of the mould.

Garnish with some chopped mixed nuts and rose petals.

Tap the mould nicely 2-3 times to level the chocolate.

Now keep it in refrigerator for 10 minutes.

After 10 minutes demould the chocolate from the mould.

Rabdi chocolate bars are ready! Enjoy!
