Start preheating the oven to 320F/160C. Lower heat will allow for the cake to rise more evenly.Grease a large baking dish and set it aside. Then, sift all of the dry ingredients (other than sugar) into a large mixing bowl.

Add the sugar and whisk all of the dry ingredients to incorporate.

Add all of the liquid ingredients (other than the hot water) to the bowl with the dry ingredients and whisk until the batter is evenly combined.Then, add the boiling hot water and whisk once again. Don't be afraid to add the hot water, it won't curdle the eggs!Finally, pour the batter into the greased baking dish and bake for 40min on the middle oven rack. Once the cake is done, let it cool completely before preparing the frosting!

To make frosting you will need to sift the cocoa powder and the confectioners' sugar together, then add the cold mascarpone cheese.Mix mascarpone with the dry ingredients using an electric mixer until evenly incorporated (1-2 minutes). Then, add the cold heavy cream and keep mixing until it reaches the desired consistency. Be careful not to overmix or the cream will curdle! Frost the cake right away and top with your favorite toppings!
