Preheat the oven to 175C (fan forced) and lightly grease a bundt pan, careful to go into all the crevices. In a large mixing bowl beat together the sugar and butter, until light and fluffy. Add the vanilla extract and beat for a few seconds to combine. Add the eggs one at a time, making sure each has been fully incorporated before adding the next. In a separate bowl, mix together the dry ingredients and then add a third of it to the sugar/butter/eggs mixture. Add in half of the mascarpone cream. Add a third of the dry ingredients, then the second half of the mascarpone cream. Finally add the last third of the dry ingredients (The batter is thickish at this point). Mix in the hot coffee, until you have a smooth batter. Transfer the batter into the prepared bundt pan, smoothing out the top. Lightly tap the pan on a flat surface to ensure the batter has filled all the crevices. Bake in the preheated oven for about 45-50 minutes or until a long toothpick inserted into the thickest part of the cake comes out clean. Allow the cake to cool in the pan for about 20 minutes before upending it to a wire rack to cool completely.
For the glaze heat the cream in a pan and place the chocolate and coffee in a small pot with a pouring spout. When the cream begins to shimmer and before it boils (don’t let it boil as evaporation will reduce the liquid volume) pour it over the chocolate and coffee. Wait a few minutes before stirring, until the glaze becomes homogenous and is smooth and silky. Pour the glaze over the cooled cake, have some fun doing this! Slice and enjoy!
