Pre-heat the oven to 350F/180C. Grease and flour or spray a 10 inch bundt pan.
In the mixing bowl beat the sugar, eggs and yolk for approximately 4 minutes or until light and fluffy. Add the salt, mascarpone and vanilla, beat to combine.
Sift in the flour, baking powder and baking soda, beat 1 minute to combine. Divide the batter evenly into 3 bowls. One bowl sift in the cocoa and 1½ tablespoons of the coffee, whisk to combine. The second bowl add the remaining coffee and combine. The third bowl add the milk and combine.
Starting with the cocoa and coffee batter spread evenly in the pan, top with the coffee then with the milk batter. Bake for approximately 35-40 minutes, test with a toothpick for doneness. Let cool 15-30 minutes in the pan, move to a wire rack to cool, then drizzle with the chocolate glaze before serving. Enjoy!
FOR THE CHOCOLATE GLAZE
In a small / medium bowl via bain-marie, add the cream, butter and chocolate broken in pieces, heat over medium heat until the butter is melted and the mixture is hot. Remove the pot from the heat and stir until the mixture is smooth. Let the glaze cool before drizzling.
Notes
How to store the Tiramisu bundt cake
Store in an airtight container at room temperature for up to 2–3 days. You can refrigerate it for a few more days, but let it come to room temperature before serving. It is best to freeze the cake without the glaze, wrap it tightly and then freeze for up to 2 months. Thaw overnight in the fridge, then bring to room temperature before glazing.
