Introduction
Chocolate Rum Cake is one of those desserts that feels like a celebration all on its own. With its rich layers of chocolate and a subtle hint of rum, it’s the perfect treat for special occasions—or just because you feel like indulging. I love how the dark chocolate ganache and apricot jam bring everything together, adding just the right amount of sweetness. Trust me, this is a cake you’ll want to bake again and again.

Instructions
Make the Cake
Prepare a rich and moist chocolate sponge that serves as the foundation for this decadent dessert.
Preheat and Prepare:
Preheat your oven to 350°F (175°C). Grease and line a 9-inch round cake tin with parchment paper to prevent sticking.
Melt Chocolate and Butter:
In a heatproof bowl, melt the dark chocolate and butter over simmering water, stirring occasionally until smooth. Remove from heat and let it cool slightly.
Whip the Egg Yolks and Sugar:
In a large bowl, whisk the egg yolks and muscovado sugar together until pale and creamy. Stir in the melted chocolate mixture and dark rum.
Combine Dry Ingredients:
In a separate bowl, mix the all-purpose flour, almond flour, baking powder, and salt. Fold the dry ingredients into the chocolate mixture until just combined.
Beat Egg Whites:
In another bowl, whisk the egg whites until stiff peaks form. Gently fold the egg whites into the batter, one-third at a time, being careful not to deflate the mixture.
Bake:
Pour the batter into the prepared tin and bake for 30–35 minutes, or until a skewer inserted into the center comes out clean. Let the cake cool completely on a wire rack.
Make the Filling and Frosting
Whip up a creamy chocolate frosting that perfectly complements the cake’s bold flavors.
Prepare the Chocolate Frosting:
Melt the dark chocolate and butter over simmering water, stirring until smooth. Allow it to cool to a spreadable consistency.
Assemble the Cake:
Slice the cooled cake horizontally into two layers. Spread a thin layer of apricot jam on the bottom layer, followed by a layer of chocolate frosting. Place the second layer on top and cover the entire cake with the remaining frosting.
Optional Chocolate Ganache
Add an extra layer of indulgence with a smooth, glossy ganache for a truly luxurious finish.
Make the Ganache:
Melt the dark chocolate, half-and-half, and butter together in a heatproof bowl. Stir in the egg yolks and rum until smooth. Pour the ganache over the frosted cake for an extra decadent finish.
Pro Tips
- Don’t have a piping bag? No problem! Use two sturdy plastic food bags layered together for extra strength. Snip a small corner off one end, and you’re ready to pipe frosting or ganache with ease.
- For the best texture, let the cake sit at room temperature for 15–20 minutes before serving to allow the frosting and ganache to soften perfectly.
