If you don't have powdered sugar, first grind sugar and keep aside.
Take a big and wide bowl and add ice cubes to it, followed by some water.
Now place the another bowl (which was kept in refrigerator for chilling) in the center of the big bowl carrying ice water.
Add the cream and beat it with the electric beater to stiff peaks.
Once its double in volume, add in grinded sugar and again beat it to form peaks.
Once its whipped, add in milk, butterscotch essence, yellow food colour, praline (reserve some in airtight for garnishing) and mix well (no need to beat).
Transfer the mixture to an air tight container and freeze for a couple of hours.
Once frozen serve after garnishing with leftover praline.
