Start by boiling water, butter, sugar, and salt in a small saucepan. Once melted, remove from heat and stir in flour until it forms a smooth ball. Let it cool for 5 minutes before adding eggs.

Add eggs one at a time, mixing thoroughly after each addition. Stir in vanilla extract to give the dough a warm, fragrant flavor. The dough should be thick but pipeable.

Transfer the dough into a piping bag fitted with a star tip. Pipe small 1-2 inch bites onto parchment paper or a silicone mat, making sure they are spaced evenly for even cooking.

Preheat your air fryer to 375°F (190°C). Place the churro bites in a single layer and cook for 8-10 minutes until golden brown. Shake the basket halfway through to ensure even crisping.

While warm, toss the churro bites in a mixture of sugar and cinnamon. This helps the sugar stick perfectly and gives them that classic churro flavor.

In a small saucepan, heat the heavy cream until just simmering. Remove from heat and stir in chocolate chips until smooth and glossy. Serve warm alongside the churro bites.
