In a bowl, sift together the flour, baking powder and salt. Stir in the brown sugar. In a separate bowl, whisk the eggs. Add the milk and vanilla extract and whisk again. Whisk in the dry ingredients until smooth.

In a deep wide pan, heat frying oil top 375 degrees F. Hold your finger over the bottom of the funnel or use a funnel cake dropper and fill it with the batter. Hold the funnel over the hot oil and remove your finger then immediately start drizzling the batter into the oil, moving the funnel around to make a criss-cross or scribbly design. Fry until golden brown on one side then flip it over to fry the other side. Remove the funnel cake from the oil with a slotted spoon or spatula and drain on a paper towel. Mix the sugar with the cinnamon and sprinkle the funnel cakes heavily with it. Serve immediately.
