Instead of the whipping cream and condensed milk, you can make using a sachet of non-diary whipped cream powder made as per instructions, and beat in a 250 ml pack of thick cream.
If you don't have peanut candy, you can make some praline:
For praline:
1/4 mixed nuts (cashews, pistachios, almonds)
1/2 cup sugar
3-4 tbsp water
To make praline, coarsely chop the nuts .
Keep a large aluminium foil well greased and set aside.
Add sugar with water, just enough to wet the sugar into a non-stick saucepan and bring to cook.
Continuously keep stirring it, till the whole sugar melts and slowly starts to caramelise.
Keep stirring to avoid it from getting burned and cook on medium flame.
Once the color changes, put in the nuts, give a quick stir and quickly pour onto the greased aluminum foil and spread.
Leave it to cool. Slowly peel off the foil, put the praline into a plastic bag and crush using a rolling pin. Use as required.
