Hazelnut biscuit roll: Amaretto cream sponge cake
Catching sight of a sun-drenched terrace of a family-run pastry shop in Vienna right as the afternoon coffee pots begin to brew introduces you to a legendary dessert craft. Today, we are mastering an absolute blockbuster baking milestone that has triggered a permanent, frantic obsession across modern lifestyle food blogs: authentic German Hazelnut Biscuit Roll, known across old-school European bakeries as Haselnuss-Biskuitrolle. Originally designed by elite court confectioners to celebrate the autumn nut harvest, wrapping a cloud-like, flourless sponge around a boozy, aromatic cream core transforms basic pantry goods into pure heritage luxury.
The beautiful stroke of culinary genius in this streamlined pastry blueprint relies on dual-protein egg whipping and an intense boozy syrup saturation technique. Instead of working with heavy, dense butter doughs that crack or turn tough when folded, we are whipping fresh whole eggs into an airy foam matrix, folding it with finely ground roasted hazelnuts and a touch of starch to ensure an impossibly moist, flexible crumb. Heavily soaked with a hot pool of sweet almond amaretto liqueur and premium aged cognac, and slathered under a dense velvet cloud of whipped dairy cream, every single slice melts completely in your mouth. Grab your deepest mixing bowls, ready those baking sheets, and let us get this shimmering bakery classic rolling away!

For the Cloud-Like Hazelnut Biscuit Sponge
- 400 g premium peeled hazelnuts (roasted and ground completely fine)
- 25 g fine pastry flour
- 50 g cornstarch
- 6 large fresh eggs (divided into separate whites and yolks)
- 150 g white granulated sugar
- 1 pinch fine sea salt
- As needed extra powdered sugar strictly for dusting down your rolling towel
For the Boozy Infusion & Velvet Cream Cushion
- 400 ml heavy whipping cream (chilled)
- 3 tbsp authentic Italian amaretto liqueur (or sweet almond syrup)
- 2 tbsp premium aged cognac
- 2 packets fragrant vanilla sugar
- 1 packet heavy whipping cream stabilizer (sahnesteif style)
- To decorate: 50 g extra chopped hazelnuts and a heavy snow layer of confectioners sugar
Step-by-Step
Let us conquer that airy dual-protein egg-whipping ritual first to establish our flexible sponge base. Crank your oven dial to 180C (350F) and line a massive flat baking sheet with a fresh layer of parchment paper. Separate your fresh eggs cleanly into two deep bowls. Drop your egg whites and a pinch of fine sea salt into a cold bowl, whipping the mass aggressively with a hand mixer on high speed until rock-hard, stiff peaks stand firm. In your second bowl, beat the egg yolks and white granulated sugar together for a solid 5 minutes until a pale, voluminous, and creamy ribbon forms.
Sift your pastry flour and cornstarch directly into the sweet yolk pool, adding your finely ground roasted hazelnuts. Gently fold one-third of your stiff egg white cloud into the heavy nut matrix using a rubber spatula to loosen the paste, then fold in the remaining whites portion-by-portion with a smooth, looping motion to preserve all that trapped air. Ladle the fluffy brown batter evenly flat all over your parchment pan floor, and plunge the tray onto the oven’s middle rack to bake patiently for exactly 10 to 12 minutes until a toothpick emerges clean.
Lay a clean, damp kitchen cloth flat across your workbench, dusting the surface heavily under a cloud of powdered sugar. Immediately flip your piping-hot hazelnut sponge upside down onto the sugary towel, peeling the hot parchment paper off the floor with a slow, confident motion. Grab the edges of the damp cloth and gently roll the empty sponge sheet up tightly from the wide bottom edge straight to the top, molding the layer into a dense log cylinder—this critical memory step prevents the nut crust from cracking or tearing later! Let the roll sit quiet on your counter until completely cold.
While the sponge cools down, let us execute our velvet amaretto cream cushion matrix. Pour your chilled heavy whipping cream into a cold mixing bowl, beating the liquid on high speed while slowly raining in your cream stabilizer and fragrant vanilla sugar until incredibly stiff peaks stand firm. In a small cup, stir your amaretto liqueur and aged cognac smoothly together to form your boozy saturation pool.
Carefully unroll your cold hazelnut sponge cylinder flat onto your workspace. Drizzle the boozy amaretto cognac liquid uniformly all over the interior brown walls, letting the nut fibers drink up the infusion pool. Use an offset spatula to smear three-quarters of your stiff whipped cream cloud evenly flat over the wet cake sheet, keeping a clean 1-inch boundary at the far top margin.
Reroll the loaded sponge sheet up rhythmically and tightly from the wide edge to the top, sliding the finished log onto a gorgeous presentation platter with the seam resting flat on the floor. Slather your remaining whipped cream uniformly all over the outer jacket of the roll, and shower a dense rain of chopped hazelnuts and extra powdered sugar across the wet armor. Plunge the platter instantly into your fridge to chill down for a patient minimum of 3 hours, slice into massive rustic wheels, and dive straight into pure Austrian confectionery paradise!
