Cook sausages in a frying pan or skillet over medium heat until fully cooked. Let them cool slightly and insert a skewer into each sausage.
Make pancake mix according to recipe for 2 cups of mix. Add 1/3 cup more of mix little at a time until thick enough to fall slowly out off the whisk. (If it gets too thick you can add a splash of milk)
Pour vegetable oil into a deep fryer or large pot until it's about 4 inches deep. Heat the oil to 350°F (175°C).
Dip each sausage into the pancake batter, ensuring it is fully coated. Let any excess batter drip off. (I find it best to pour the batter into a tall cup for dipping to help coat the sausage better)
Carefully place the coated sausages into the hot oil. Fry in batches, turning occasionally, until golden brown and crispy (about 2-3 minutes per side).
Use tongs to remove the sausages from the oil and place them on a paper towel-lined plate to drain any excess oil.
Serve the Pancake Sausage on a Stick warm with maple syrup for dipping and top with powdered sugar, if desired.
