Beat egg with hand mixer until fluffy; beat in remaining ingredients until smooth. Spray griddle or flat frying pan with non-stick cooking spray. Test griddle by sprinkling a few drops of water - if spits heat is just right.
Using a large serving spoon pour about 3 tbsp batter onto hot griddle. (I usually do 4 at a time.) Cook pancakes until puffed and dry around edges, flip and cook the other side until golden brown. Stack on plate and keep warm in oven set @ 200 F while you cook the rest. Serve with warm maple syrup and warm apple sauce.
