This is not the original trifle recipe but I've made slight changes according to the available ingredients I had at home. This is definitely a treat for the kids.
Jelly-1cup (I used raspberry flavour)
Whipped cream to serve
Glazed cherries for decoration
Split the sponges in half then spread each half thinly with jam. Sandwich each half back together and cut into quarters. Place them at the base of a serving bowl. Add the jellies(cubed) and then pour some custard.
Whip the cream along with sugar (as per your taste) until slightly stiff. Spoon a little whipped cream on custard and decorate with cherries.
Note: I usually use sponge cake when I am short of trifle sponges and add fruits instead of jellies. You can make it as per your tastes.
