Mix Wet Ingredients:

In a medium-sized mixing bowl, whisk together the milk, egg, vanilla extract, and melted butter until well combined.

Add Dry Ingredients:

Stir in the salt, baking soda, and granulated sugar until fully incorporated. Gradually fold in the flour, mixing until the batter is smooth and lump-free.

Prepare for Frying:

Transfer the batter to a gallon-sized resealable plastic bag. Set aside for a few minutes to rest. Meanwhile, pour vegetable oil into a frying pan to a depth of about 1/2 inch and heat over medium-high heat.

Check Oil Temperature:

Test the oil by dropping a small amount of batter into it. If the batter sizzles and bubbles form around its edges, the oil is ready. If not, adjust the heat accordingly.

Fry the Bites:

Snip a small corner off the plastic bag and squeeze the batter into the hot oil, forming small circles or bite-sized shapes. Fry until the underside is golden brown, then gently flip to cook the other side.

Drain and Dust:

Use a slotted spoon to transfer the funnel cake bites to paper towels to drain excess oil. Dust with powdered sugar before serving.
