Mix the ingredients in the order listed.
Pour the mixture into a medium-sized oven dish and bake at 329°F (165 °C) for about 30 min.
Take it out of the oven, let it cool for 10-15 min. and then dig out holes (with a pepper corer, a cork or something else of the sort).
Fill the holes with the cream that you've prepared ahead of time and place the dug out pieces on top of them, to get a "button" effect.
Put it in the fridge to cool for about 2-3 hours.
