In a large mixing bowl, combine the slightly beaten eggs, milk, and packed brown sugar. Whisk together until well combined.
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; a few lumps are perfectly fine!
In a deep fryer or a heavy-bottomed pot, heat about 2 inches of vegetable oil over medium-high heat until it reaches 350°F (175°C). Test the oil by dropping a small spoonful of batter into it; it should sizzle and rise to the surface.
Using a piping bag or a squeeze bottle, carefully squeeze the batter into the hot oil in a zigzag pattern, creating long, wavy shapes. Fry for 2-3 minutes on each side or until golden brown.
Use a slotted spoon to remove the fries from the oil and place them on a plate lined with paper towels to drain any excess oil. While still warm, dust lightly with powdered sugar.
Serve your Funnel Cake Fries warm. Optionally add toppings like chocolate sauce, whipped cream, or fresh fruit. Enjoy your homemade fair food!
