Prepare the Dough:

• In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.
• In a separate bowl, whisk the milk, egg, melted butter, and vanilla extract.
• Gradually combine the wet and dry ingredients, stirring until a soft dough forms.

Shape the Doughnut Holes:

• Lightly flour your hands and roll the dough into small 1-inch balls.
• Set them aside on a parchment-lined tray.

Heat the Oil:

• In a deep pot, heat the vegetable oil to 350°F (175°C).
• Use a kitchen thermometer to maintain a steady temperature.

Fry the Doughnut Holes:

• Carefully drop a few dough balls into the hot oil. Avoid overcrowding.
• Fry for about 2 minutes per side, turning them until golden brown.
• Use a slotted spoon to transfer them to a paper towel-lined tray to drain excess oil.

Coat with Cinnamon Sugar:

• In a bowl, mix the granulated sugar and ground cinnamon.
• Brush warm doughnut holes lightly with melted butter and roll them in the cinnamon sugar mixture.

Serve & Enjoy!

• Serve immediately while warm for the best texture and flavor!
