Simple Sweetened Condensed Milk Trifle

In a saucepan, mix the sweetened condensed milk, cornstarch, egg yolks, salted margarine, and milk.

Heat the mixture over the stove and cook until it thickens.

Remove from heat and stir in the vanilla extract.

Slightly dip the Maria cookies (or plain tea biscuits) in milk mixed with a little vanilla extract.

Assemble the trifle by layering the custard mixture, soaked cookies, and whipped topping.

Garnish with chopped white chocolate.
