Gather all ingredients.

Beat eggs and 1/4 cup sugar in a large bowl until thick and lemon-colored; mix in 1 teaspoon vegetable oil.

Combine 1 1/2 cups of flour, baking powder, and salt; gradually add to egg mixture, mixing well until evenly combined.

Turn dough out onto a floured board and knead thoroughly until dough is smooth.

Shape dough into 16 even-sized balls. Flatten and roll each one into a very thin circle about 5 inches in diameter. Let stand uncovered on waxed paper for about 10 minutes.

Meanwhile, combine 1 cup sugar and cinnamon in a small bowl until evenly mixed; set aside. Heat oil in a deep pan to 350°F (175°C).

Lower one circle of dough carefully into the hot oil; fry until golden, turning once, about 30 seconds on each side. Transfer to a paper towel-lined plate to drain; sprinkle with cinnamon-sugar mixture.
