In a bowl, mash the pumpkin. Add the egg, flour, baking powder, and cinnamon. Mix well to form a batter.
Heat the oil in a frying pan over medium heat.
Drop spoonfuls of batter into the hot oil, flattening slightly.
Fry for 2-3 minutes per side, or until golden brown and cooked through.
Remove the fritters from the pan and drain on paper towels.
Meanwhile, make the toffee sauce: In a saucepan, combine the brown sugar, butter, and cream. Heat over medium heat, stirring constantly, until the sugar dissolves and the sauce thickens slightly.
Drizzle the toffee sauce over the warm fritters and serve immediately.
