Heat fry oil to 350-375F. Mix dry ingredients in a medium sized bowl and mix wet ingredients in a separate medium sized bowl. Pour the wet ingredients into the dry ingredients and mix until batter is combined, but do not over-mix. Take the hot dog slices and coat them with the extra flour. Dip and roll hot dogs 1 at a time into batter and put them into fryer. Fry for around 3 to 5 minutes or until outside is golden brown. Take out of oil and shake off excess oil and serve.
