In a large mixing bowl, combine gluten-free flour blend, sugar, baking powder, and salt. Whisk until combined.

In a separate bowl, whisk eggs, milk, and vanilla extract until frothy.

Gently fold wet ingredients into dry mixture until a smooth batter forms.

Transfer the batter into a piping bag or Ziploc bag.

Heat oil in a skillet over medium-high heat to 375°F (190°C).

Squeeze batter into hot oil in 4-inch long lines. Fry in batches until golden brown.

Remove fries and drain on a wire rack, dusting with powdered sugar while warm.

Serve immediately with toppings like whipped cream or chocolate sauce.
