1. In a bowl, whisk the milk and egg together; stir in the flour, baking powder, and salt until the mixture is smooth.
2. Heat the oil in a heavy deep skillet or saucepan over medium heat until it is hot enough to sizzle and brown a crust of bread (about 365°).
3. Using tongs, dip the figs, one at a time, into the batter, turning to thickly coat.
4. Fry 1-2 fritters at a time in the hot oil until golden all over, about 2 minutes per side.
5. Drain the fritters briefly on a double layer of paper towels; then transfer to a wire rack and sprinkle generously with powdered sugar; serve warm.
