Baba al Rhum is a traditional Neapolitan dessert that is made with a sweet yeast dough that is soaked in rum syrup. The dough is made with flour, sugar, eggs, butter, and yeast. The rum syrup is made with rum, sugar, and water. To make the dough, mix the flour, sugar, eggs, butter, and yeast together in a bowl. Knead the dough until it is smooth and elastic. Let the dough rise for about an hour. Preheat the oven to 350 degrees F. Grease a baba mold with butter and dust it with flour. Fill the mold with the dough and bake for about 20 minutes, or until the baba is golden brown. While the baba is baking, make the rum syrup. Mix the rum, sugar, and water together in a saucepan and bring to a boil. Reduce the heat and simmer for about 10 minutes. When the baba is done, remove it from the oven and let it cool for a few minutes. Pour the rum syrup over the baba and let it soak for about 30 minutes. Serve the baba al Rhum with whipped cream and enjoy!
