Preheat oven to 175°C. Unroll phyllo dough on a large work surface. Using a 23 x 33 cm baking dish as a guide, cut phyllo sheets to fit the pan, discarding trimmings. Keep the phyllo covered with a damp cloth to prevent drying.

Melt butter in a microwave-safe bowl. In a separate bowl, gently melt Nutella until pourable. Generously brush the baking dish with some melted butter.

Place one sheet of phyllo in the buttered baking dish and brush with melted butter. Repeat layering and buttering five more times, for a total of six sheets.

Drizzle 120 g of melted Nutella over the layered phyllo and spread evenly. Sprinkle with approximately 45 g chopped hazelnuts. Drizzle with 85 g honey.
05 -
Layer six additional phyllo sheets, brushing each with melted butter. Spread another 120 g melted Nutella over the top layer, add 45 g hazelnuts, and drizzle with 85 g honey.
06 -
Layer the remaining phyllo sheets on top, brushing each with melted butter.

Using a sharp knife, cut the assembled baklava into 12 even squares, then cut each square diagonally into two triangles, yielding 24 pieces. Brush the surface with remaining melted butter and sprinkle with the remaining hazelnuts.
08 -
Bake in the preheated oven for about 30 minutes, or until golden and crisp. Immediately drizzle the hot baklava with the remaining 170 g honey. Allow to set at room temperature for at least 2 hours.

Gently re-melt the remaining Nutella. Transfer to a small piping bag or resealable bag with a trimmed corner, and drizzle over the cooled baklava. Slice and serve.
