Bringing the decadent, highly artistic energy of an upscale European pastry boutique directly into your home kitchen transforms a standard weekend baking session into an absolute celebration of premium textures. These spectacular dessert squares completely redefine traditional sheet cakes, layering a flourless, rich chocolate-nut foundation with an incredibly smooth, Italian-style dairy core and glossy summer fruits. It is an exceptional selection for grand holiday family reunions, festive milestone celebrations, or sophisticated Sunday high teas when you want to treat a crowd of 30 guests to pure handcrafted luxury. Slicing these colorful, elegant blocks fills your entire living space with an absolutely hypnotic perfume of warm rum, toasted nuts, and dark melted cocoa, automatically drawing everyone toward the presentation counter.
The true culinary operational brilliance behind this deeply satisfying layered masterpiece relies entirely on a flourless nut-sponge technique and a careful cold-set gelatin binding rhythm. Instead of utilizing standard grain flours, the cloud-soft base achieves its incredible velvet loft and rich structural density purely through an aggressive whip of ten separate eggs, melted dark chocolate, and finely ground hazelnuts. Spreading a velvety mixture of low-fat cream cheese and rich, buttery Italian cream cheese over the halved bases builds a highly stable, dense structural cushion that effortlessly carries a massive load of fresh orchard fruits. It is a foolproof artisan blueprint that delivers a striking texture contrast, ensuring that every single bite yields a perfect combination of nutty chocolate snap, silky dairy mousse, and bursting fresh cherry sweetness.

Step-By-Step
Chop your dark chocolate into small pieces, transfer the chunks into a heat-resistant bowl, and melt it carefully over a warm water bath before setting it aside on your workspace to cool down. Separate your ten large eggs, dropping the whites into an exceptionally large, clean mixing bowl and the yolks into a separate ceramic container. Add 150 grams of softened butter, 150 grams of white sugar, a pinch of salt, and one packet of vanillin sugar to the yolks, whipping aggressively with your hand mixer for 5 minutes until a thick cream forms. Mix your ground hazelnuts and active baking powder, then alternate folding the nut blend, the melted chocolate, and four tablespoons of dark rum into the egg cream.
Whip your ten egg whites on high speed until completely stiff peaks form, then use a flexible silicone spatula to gently fold the airy foam baseline into the heavy chocolate nut dough. Greas a large deep universal roasting pan measuring 32 by 38 centimeters, dust the floor with flour, smooth the batter inside, and bake at 200°C for exactly 20 minutes before letting it cool on a wire rack. Slice the cooled cake cleanly in half to create two matching 32 by 19-centimeter rectangles, and place each disk flat onto its own large serving board workspace. Soak your nine gelatin sheets in a bowl of cold water while you handle the remaining cold dairy elements.
Whisk your low-fat cream cheese, rich mascarpone, one packet of vanillin sugar, and 125 grams of white sugar together in a massive bowl until a seamless velvety mirror develops. Squeeze out your soaked gelatin sheets, dissolve them carefully over low heat in a small pan, stir in two tablespoons of the mascarpone cream, and then pour everything back into the main bowl. Spread this thick cream uniformly over both chocolate nut floors, smooth the surface, and chill in the refrigerator for exactly 3 hours to establish a highly stable cushion. Wash and pit your fresh cherries, arrange them over the set cream, pour a boiling glaze made of the glaze powder, cherry nectar, 50 grams of sugar, and water over the fruit, chill for 45 minutes, slice into 30 bars, and decorate with whipped cream and chocolate curls.
