This recipe is for a fluffy tiramisu cake made with a base of crushed Oreos, a rich batter of cream cheese, egg yolks, and heavy cream, and then mixed with meringue. It's easy to make by simply mixing and chilling, making it perfect for beginner cooks. It's also cute to look at, making it ideal as a gift or for enjoying at home. If using heat-sensitive mascarpone cheese, be sure to avoid heating the cream cheese and be careful not to deflate the meringue when mixing it with the batter.
