In a large bowl, whisk all the dry ingredients until well combined: flour, sugar, baking powder, salt, sugar, cardamom, and nutmeg.
Gently add the liquid ingredients: eggs, butter, and milk. Combine until the mixture comes together and the dough is smooth. If the dough is too sticky, add a little bit of flour. If it's too hard, add a little bit of water. The dough shouldn't be too sticky when touched, but it's better to err on the side of less flour than more flour.
Roll out the dough into a 1-inch thick rectangle. Cut into bite-sized pieces or triangles like in the picture.
Pour vegetable oil into a large saucepan until it's at least three inches deep (or about 5 centimeters). Too little oil will result in flatter mandazi. Heat over medium until the oil is 350℉ (180℃).
Fry the mandazi until golden brown, 3-5 minutes, depending on the size. Remove them with a slotted spoon and drain on a paper towel. Serve warm.
