Instructions
Melt dark chocolate
Place chopped dark chocolate in a microwave‑safe bowl. Heat in 30‑second bursts, stirring after each burst, until fully melted and smooth.
Time: PT2M
Melt butter
In another microwave‑safe bowl, melt the butter in 30‑second intervals, stirring until smooth.
Time: PT1M
Cool chocolate and butter
Set both melted chocolate and butter aside to cool to about room temperature (≈20‑25°C).
Time: PT5M
Whisk eggs and sugars
In a large mixing bowl, crack the eggs, add white sugar and muscovado sugar. Beat with the electric mixer on medium speed until the mixture turns pale and fluffy (about 5 minutes).
Time: PT5M
Add hazelnut flour
Stir the hazelnut flour into the egg‑sugar mixture until just combined.
Time: PT1M
Incorporate dry ingredients
Sift the all‑purpose flour, cocoa powder and baking powder over the bowl. Fold with a spatula until the batter is smooth and no streaks remain.
Time: PT2M
Add cream and melted butter
Pour the room‑temperature cream and the cooled melted butter into the batter. Whisk on low speed until fully incorporated.
Time: PT2M
Add rum and chocolate
Stir in the dark rum (or vanilla extract) and the melted chocolate from step 1. Fold until the batter is uniformly dark and glossy.
Time: PT2M
Prepare the cake pan
Butter the cake pan and line the base with parchment paper for easy release.
Time: PT2M
Transfer batter to pan
Pour the batter into the prepared pan and smooth the top with a spatula.

Preheat the oven to 160°C (convection). Bake the cake for 40‑45 minutes, or until a knife inserted in the centre comes out clean but still slightly moist.
Time: PT45M

Cool the cake
Allow the cake to rest in the pan for 10 minutes, then turn it onto a cooling rack and let it cool completely (about 15 minutes).
Time: PT25M
Brush with apricot jam
Warm the apricot jam briefly (microwave 10‑15 seconds) and brush a thin layer over the top of the cooled cake.
Time: PT2M
Add toppings
Scatter the toasted hazelnuts over the jam‑glazed surface and drizzle small dollops of praliné for extra crunch.

Troubleshooting
Cake is dense and not moist
Ensure the eggs and sugars are whisked until very pale and fluffy; avoid over‑mixing after adding flour.
Cracks on the surface
Do not open the oven door during the first 30 minutes; bake at a slightly lower temperature if your oven runs hot.
Chocolate glaze slides off
Make sure the cake is completely cool before applying any glaze; chill the glaze slightly before spreading.
Storage
Refrigerator: Store in an airtight container for up to 5 days.
Freezer: Wrap tightly in plastic wrap and foil; freeze up to 2 months.
Room temperature: Can sit at room temperature for 1 day if covered.
Make-Ahead Tips
