While the cake is still warm poke holes in the cake with the handle of a wooden spoon

Slowly pour condensed milk over the cake filling the holes and making sure it runs down the sides

Cover and chill for at least 2 hours, even better over night

Mix the whipped topping and instant pudding

Spread over chilled cake

Either chill for 30 minutes or serve imediately

Garnish with strawberries right before serving
