Meringue Cake Napoleon Mille Feuille

Meringue Cake Napoleon

Meringue Cake Napoleon

Just a simple combination for a few of my favorites : meringue, toasted nuts ,caramel buttercream and puff pastry, as simple as that. Nothing original or new, but the taste with those combined, is something worth a try. Any meringue cake is already a quite delicate dessert, and adding crispy, flaky puff pastry to it, makes the cake even more decadent. This meringue cake/ Napoleon Mille Feuille recipe is quite flexible, in the meaning that many ingredients can be either omitted or replaced.

I love the taste of toasted walnuts with any meringue cake, but it can also be replaced with toasted almonds or pecans, or just left out if preferred. As well as the caramel buttercream, it can be replaced with any preferred cream, frosting. In fact my first testing was with chocolate buttercream, which I loved it as well.But decided to stick to my classic caramel buttercream. As always, not much to add, lets just get to the recipe.

Happy baking!
