In a large bowl, whisk together flour, baking powder, salt, and sugar.

In another bowl, mix eggs, milk, and vanilla extract. Gradually add the wet ingredients to the dry ingredients, stirring until smooth.

Heat vegetable oil in a deep pan to 350°F (175°C).

Pour batter into a squeeze bottle or piping bag. Pipe small dollops into the hot oil.

Fry until golden brown, about 1-2 minutes per side.

Remove with a slotted spoon and drain on paper towels.

Dust generously with powdered sugar before serving.
