In a large bowl, whisk together warm water, granulated sugar, and yeast; let sit until foamy.

Add eggs, softened butter, vanilla extract, and salt; mix to combine.

Gradually add flour, mixing until a soft dough forms.

Knead dough on a lightly floured surface until smooth and elastic.

Place dough in a greased bowl, cover, and allow to rise until doubled in size.

Roll the dough out to about ¼-inch thickness.

Cut dough into squares or rectangles.

Heat oil in a heavy pot or Dutch oven to 350°F (175°C).

Fry the dough pieces in batches until golden on both sides.

Remove and drain on paper towels.

Dust generously with powdered sugar before serving.
