Beat the butter and the icing sugar with a pinch of salt until very creamy and white. Melt the chocolate, add rum, cocoa powder and ground almonds.
125 g butter, 120 g icing sugar, 1 pinch salt, 200 g dark chocolate, 150 g milk chocolate, 5 tbsp rum, 2 tbsp cocoa powder, 200 g ground almonds
Slowly incorporate the chocolate mixture into the butter. Take approx. 1 tsp. of the mass and roll it to a ball, put it on a baking tray with parchment paper on top and put the rum balls in the fridge for 10 minutes.
After cooling, you can roll them in your hands to a smooth ball. Cool again for at least 10 minutes.
In the meantime melt 2/3 of the dark chocolate for the decoration at maximum 45 °C. Add the last 1/3 once the chocolate has fully melted. Cover the rum balls in chocolate, one at a time, and use a praliné-rack or an oven rack to create some texture by wheeling every praliné back and forth until it looks kind of like a hedgehog. Or cover them in chocolate and roll them in cocoa powder.
