Mocha Rum Cake with Espresso Glaze and Chocolate Ganache 

Make the Cake: Place a heatproof bowl over a pot of steaming water. Add the chopped bittersweet chocolate and butter to the bowl. Stir continuously to prevent the chocolate from burning. Keep stirring until the mixture is smooth.

Take it off the heat and mix in the rum, coffee, espresso, vanilla, and sugar. Add the eggs, one at a time, and beat until well combined and smooth.

Using a medium bowl, whisk the flour, baking soda, and salt. Gradually beat the dry ingredients into the wet until combined and smooth 

Put the batter into the bundt pan and bake it in the oven for around 75-85 minutes or until a toothpick comes out clean.

Let it cool completely before removing and placing it on a wire rack with a tray underneath. Heat the milk in the microwave for 30 seconds using a small bowl. Whisk in the instant espresso until dissolved. 

Mix the Glaze: In a bowl, put the powdered sugar and slowly pour in the espresso milk. Whisk until everything is mixed and smooth. Pour over the bundt cake and allow it to drip down the sides.

Make the Ganache: Using a small pot, bring the heavy whipping cream and rum to a simmer. Pour over the chocolate chips in a heatproof bowl . Allow it to sit for 1 minute before whisking until smooth. Gradually pour the ganache over the bundt cake 

Finish: Sprinkle toasted coconut and mini chocolate chips on top.

Tips and Tricks

  • Use high-quality ingredients: This cake relies on the flavors of chocolate, coffee and rum, so make sure to use good quality ones. Using cheap or low-quality ingredients will affect the overall taste of the cake.
  • Add rum to taste: Depending on your preference, you can add a little or a lot of rum to the cake batter. Just remember, the more rum you add, the stronger the flavor will be.
  • Use strong coffee: The stronger the coffee, the better it will complement the chocolate and rum flavors. Don’t be afraid to brew a strong pot of coffee or use more espresso for an extra kick of flavor.
  • Let it cool completely: To avoid a soggy cake, make sure to let it cool completely before serving or adding any frosting. This will also help enhance the flavors and create a nice texture.

Variations to Mocha Rum Bundt Cake with Espresso Glaze and Chocolate Ganache 

  • Swap out the rum: If you don’t like or have rum on hand, you can substitute it with other liquors such as bourbon, brandy or even amaretto. Just make sure to use a strong liquor that will complement the flavors of chocolate and coffee.
  • Add nuts or dried fruits: For added texture and flavor, you can mix in chopped nuts or dried fruits such as raisins, cranberries or cherries into the cake batter. This will also add a nice pop of color to the finished cake.
  • Top with whipped cream: Instead of a chocolate ganache, you can top the cake with whipped cream and dust it with cocoa powder for a lighter and airy finish.
  • Make it gluten-free: You can easily make this cake gluten-free by using a gluten-free flour blend in place of regular flour. Just make sure to check the labels of all ingredients used to ensure they are also gluten-free.
  • Infuse with different flavors: Get creative and infuse the cake batter with different flavors such as peppermint extract, almond extract or even orange zest for a unique twist on this classic recipe.
  • Serve with coffee or hot cocoa: This cake pairs perfectly with a cup of hot coffee or rich and creamy hot cocoa. The flavors of chocolate and coffee will complement each other, making it the perfect dessert for any coffee lover.
  • Add a drizzle of caramel sauce: For an extra indulgent touch, you can drizzle some warm caramel sauce over the top of the cake before serving. This will add a delicious caramel flavor to each bite.

How to Store Mocha Rum Cake

Once the cake is completely cooled, you can store it in an airtight container or cover it with plastic wrap and keep it at room temperature for up to 3 days. Alternatively, you can store your Mocha Rum Cake in the refrigerator for up to 5 days.

If you want to freeze the cake, make sure to cool it completely first before wrapping it tightly with plastic wrap and then placing it in a freezer-safe container. The cake can be frozen for up to 3 months.

Before serving, make sure to thaw the cake in the refrigerator overnight and bring it to room temperature before enjoying. Freezing may slightly affect the texture of the cake, but it will still be deliciously decadent.
