Beat eggs one at a time with sugar and margarine.

Sieve flour, baking powder, salt and mix gradually with the egg mixture.

Add vanilla essence and milk until the mixture looks creamy. Add the chocolate chips and mix.

Pour the mixture into the cupcake tray and tap the baking tray on the counter twice, to remove air bubbles.

Preheat the oven to 180 degrees for 30 minutes and bake.
