Once mixture is foamy, add remaining sugar, salt, melted butter and egg and 2 cups (250g) of flour. Stir well.  Add remaining flour, stirring until combined.

Fill a medium-sized saucepan about 2-3” deep with oil. Fix a thermometer to the pan and turn heat to medium. Heat oil to  375F (190C). This should take approximately 15 minutes.

Once oil has reached temperature, fry beignets by gently lowering into oil with a strainer or with tongs. Cook about 1 ½ minutes on each side or until golden brown.
