Divide the cake into 5 equal portions. Chop them into medium sized pieces.
Leave the ice cream on the kitchen top till soft. Beat slightly using a fork.
Divide the ice cream and the mango pieces into 5 equal portions.
Line a part of cake at the bottom of an individual serve bowl. Add some ice cream and mango pieces. Mildly sprinkle cinnamon and cardamom powders.
Put in another layer of cake and finally top with remaining ice cream and mango slices.
Sprinkle chopped pistachios on top. Repeat this for the remaining 4 bowls.
Leave the trifle in the fridge for around an hour for the flavors to settle. Dig in and devour!!
You can definitely make this in a large tray, for scooping out and serving, even though individual servings look more attractive! You can fluff the cinnamon and cardamom powders into the ice-cream before layering it into the bowl.
