Thin, crunchy oat crisps dusted with cinnamon. A simple baked low calorie snack that satisfies the crunch craving without the calorie bomb.
Preheat your oven to 325°F (160°C) and line a large baking sheet with parchment paper, then lightly coat it with nonstick cooking spray.
In a medium bowl, whisk together the egg whites, unsweetened applesauce, vanilla extract, and salt until frothy—this step helps bind and lighten the mixture.
Fold in the rolled oats and 1.5 tsp of ground cinnamon, mixing until the oats are fully coated and the mixture is evenly combined.
Spread the oat mixture into a very thin, even layer on the prepared baking sheet; press firmly with a spatula for crispness.
Bake for 20 minutes, then carefully remove and sprinkle the remaining 0.5 tsp cinnamon over the top. Return to the oven and bake for an additional 7–10 minutes until deep golden and crisp at the edges.
Cool completely on the baking sheet; once hardened, break into bite-size crisps. Store in an airtight container for freshness.
