1. Start with making the batter by mixing the flour, baking powder, salt, and carbonated water. and mixing until it reaches a thicker consistency. If you find the batter is too runny, you can add a little flour. Stir completely until it is smooth.
2. Then, peel and core the apples, slice as thick or thin as you prefer. I would recommend about a half inch thick.
3. Add your oil to a deep pot with a thermometer and heat until it reaches a temperature of 350 degrees.
4. Dip each of the apple slices through the batter and let the excess fall off the apple slice.
5. Slowly lower the battered apples into the oil, frying for 3-5 minutes until they are golden brown.
6. As they come out of the oil, dip each one in a mixture of cinnamon sugar and place on a drying rack.
7. Allow the beignets to cool slightly and serve warm for a delicious treat!
