step-by-step
Let us begin with the citrus sugar drying and marbled sponge baking ritual. Scatter 225 grams of white granulated sugar evenly across a large tray. Wash 1 organic orange, slice into very thin wheels, blot dry with paper towels, and lay them flat side by side over the sugar bed to dry quiet overnight, ensuring you turn the wheels once. Open your glass of sweet canned sour cherries, pouring the red fruits through a sieve to drain the liquid completely bone dry. In a massive mixing bowl, combine 275 grams of soft butter, 1 packet of vanilla sugar, and the orange sugar crystals scraped off your dried fruit tray. Whisk on high speed for exactly 4 minutes until pale and creamy. Whisk in 5 fresh eggs one after another. Sift 300 grams of pastry flour and 3 teaspoons of baking powder over the creamed base, alternating with 5 tablespoons of whole milk, and fold gently until a smooth dough builds.
Grease a large 32 x 39 cm sheet pan and dust with flour. Spread exactly one half portion of your yellow sponge dough flat across the pan floor. Fold 2 teaspoons of cocoa powder, 2 pinches of cinnamon spice, and 2 extra tablespoons of whole milk into the remaining half portion of dough until a dark aromatic cocoa paste forms. Slather this dark paste uniformly all across the yellow dough layer, then scatter all your drained sour cherries evenly flat right over the raw dough ceilings, pressing the fruits gently halfway down. Plunge the loaded pan onto the middle oven rack rail line of a baking vault preheated to a steady heat line of 175C (350F) using traditional electric top and bottom heat settings, or 150C (300F) if utilizing a convection fan current, baking bare and uncovered free for exactly 25 minutes total until the starch walls expand wide, then let the sheet cake cool flat.
Now, handle your velvet orange pudding custard and buttercream assembly. Wash your second organic orange, friction shaving the skin into fine zest strands before squeezing out the juice. In a small cup, combine 1 packet of dry vanilla pudding powder, 50 grams of white sugar, and 5 tablespoons of your fresh orange juice, turning fast with a fork until a smooth starch slurry forms. Bring 450 milliliters of whole milk to a roaring boil inside a saucepan, stir your vanilla pudding slurry straight inside the boiling milk under a fast constant manual whisk loop, and cook for 1 final minute. Fold your orange zest strands straight into the hot thick custard pudding, place plastic wrapping film secure directly onto the hot pudding mirror surface to block skin growth, and let the custard cool completely down to room temperature. In a clean deep mixing bowl, combine your remaining 250 grams of sweet butter blocks and 2 tablespoons of sweet orange liqueur, whisking on high velocity speed for exactly 4 minutes until an absolutely fluffy white cream builds. Verify that both your whipped butter and your cooled orange custard pudding rest at the exact same room temperature; add the pudding mass tablespoon by tablespoon directly inside the whipped butter cauldron under constant medium speed machine turning until a thick uniform velvet citrus cream builds. Use an offset spatula to smoothly spread this velvet buttercream uniformly all across your cooled cherry sheet pastry ceilings, and slide the tray inside a cool storage zone for exactly 3 full hours total until solid.
Chef’s Critical Staging Secret: Coarsely chop 300 grams of dark chocolate couverture block into fine shards. In a metal bowl setup set over a hot water vapor pool pan, combine your chocolate shards and 25 grams of solid coconut fat block, stirring constantly over slow heat for exactly 3 minutes until melted into a smooth lacquer mirror, then pull the vessel off the active fire tiles to cool flat for exactly 10 minutes total. Slowly stream this warm chocolate lacquer directly right over your cold set buttercream ceilings, using your offset spatula to spread the glaze flat out to the border walls. Take a traditional wide plastic pastry comb tool, holding the teeth vertical while dragging the blade in slow rhythmic curving zigzag loops completely across the wet chocolate top shield to construct a gorgeous wavy Danube river wave matrix. Slide the cake pan proudly straight back inside your refrigerator frost lines to rest cold for 60 final minutes total to let the chocolate glaze solidify completely. Cut into 24 identical square chunks with a warm blade, garnish the summits meticulously under your sugar dried orange wheels, serve cold, and enjoy your holiday feast paradise!
