Grab your onion rings and cheese sticks. Slide half a mozzarella stick where the onion rings don’t touch, tucking a smaller ring inside a bigger one with cheese in the gap. Skewer them tightly with a toothpick so nothing moves.

Combine baking powder, fine salt, and your flour in a bowl. Give it a stir so everything’s spread out.

Take every cheese-stuffed onion ring and toss it around in your flour blend. You want all surfaces white and covered before moving them aside on a rack.

In a new bowl, use a whisk to mix up your milk with the beaten egg. Pour a little of this into any flour left and stir until smooth — no lumps here.

Submerge each floured onion stack in the batter, let extra drip off, then bury it in Panko crumbs on all sides. After that, let them chill on your rack.

Heat oil in a deep pot until it hits 350°F (175°C). Using tongs, carefully lower your Panko-crusted rings in. Don’t crowd the pot; fry a few at a time. Flip once and cook till they’re all golden — just 3–4 minutes. Move them to a towel to lose extra oil.

Pull out the toothpicks before you dig in. Hand them out hot with some marinara if you like dipping.
