Cut tortillas into triangles, strips, or festive shapes.
In a small bowl, mix the Splenda and cinnamon.
Lightly spray both sides of the tortilla pieces with oil.
Air Fry at 350°F for 4–6 minutes.
Start checking at minute 3 — grain-free tortillas brown faster.
Let chips cool 2–3 minutes so they crisp fully.
Sprinkle the cinnamon sugar onto the chips.
Add sugar-free chocolate chips + heavy cream to a microwave-safe bowl.
Microwave in 20-second intervals, stirring each time.
Stop when smooth and glossy.
Add vanilla + pinch of salt.
Serve warm with your churro chips.
