Notes:
Cooling the Dough Before Adding Egg: Make sure to let the dough cool for 5 minutes before adding the egg so the heat does not scramble the egg in the pan. The dough should be warm but not steaming.
Why a Star Piping Tip Matters: The ridges created by a star piping tip increase surface area, allowing more of the churro to crisp up in the air fryer. Plain round tips create smooth churros with less texture.
Single-Layer Arrangement: Never overcrowd the air fryer basket. Hot air must circulate around each churro bite for even puffing and browning. Cook in batches if necessary.
Coating While Hot: The cinnamon sugar adheres best to warm, buttered churro bites. Coat them immediately after removing from the air fryer for maximum coverage.
Make-Ahead Tip: You can pipe the churro bites onto parchment paper, freeze them on a baking sheet, then transfer to a freezer bag. Air fry frozen bites at 375°F for 10–12 minutes.
Dipping Sauce Pairings: Warm chocolate ganache, dulce de leche, salted caramel, or Nutella all pair beautifully with churro bites. For a Mexican twist, add a pinch of cinnamon and cayenne to melted chocolate.
Using Room-Temperature Eggs: Cold eggs are harder to incorporate into the warm dough. Let eggs sit at room temperature for 30 minutes before using.
Preventing Sticking: Lightly spraying the air fryer basket and the churro bites with oil prevents sticking and promotes even browning.
Checking for Doneness: Churro bites are done when they are golden brown, puffed, and firm to the touch. If they collapse when you press them gently, they need another minute or two.
Storage Note: Churro bites are best eaten fresh. They soften as they cool because the cinnamon sugar absorbs moisture from the dough.
