In a large bowl, dissolve yeast in warm water with a pinch of sugar. Let sit for 5 minutes until foamy.

Stir in sugar, eggs, evaporated milk, and softened butter. Mix until smooth.

Add 4 cups of flour and salt. Stir until combined. Gradually add the remaining flour until a sticky dough forms.

Transfer dough to a floured surface and knead until smooth and elastic.

Place dough in a greased bowl, cover with a damp cloth, and let rise for 1–2 hours, or until doubled in size.

Punch down the dough and roll it out to about ¼-inch thickness.

Cut the dough into 2-inch squares.

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

Fry dough squares in small batches for 2–3 minutes per side, until puffed and golden brown.

Remove and drain on paper towels or a wire rack.

Dust generously with powdered sugar before serving warm.
