First, cream the butter and sugars until light and fluffy. Beat in the egg and vanilla, then gradually mix in flour, salt, and chocolate chips. Chill the dough slightly so it’s easier to shape into balls.
Whisk together flour, baking powder, salt, sugar, milk, and vegetable oil until smooth. The batter will be thin but will crisp beautifully when fried. Keep it ready near the frying station.
Use a small scoop or spoon to form the cookie dough into 1-inch balls. Place them on a tray lined with parchment and freeze for about 30 minutes. This helps them hold their shape during frying.
Heat oil to 360°F (182°C). Carefully dip each dough ball in the batter, then lower it into the hot oil. Fry until golden brown, about 2-3 minutes, turning as needed. Remove with a slotted spoon and drain on paper towels.
Drizzle with melted chocolate and dust with powdered sugar while warm. Serve immediately for the ultimate gooey experience.
