Preheat your oven to 325°F (165°C) and prepare a baking sheet lined with parchment paper.

In a large mixing bowl, combine 1 cup of oat flour with 1/4 teaspoon of cinnamon (if using) and whisk together.

In a separate bowl, whisk together 1/2 cup of unsweetened applesauce, 2 tablespoons of melted coconut oil, and 1 egg until smooth.

Gradually add the wet mixture to the dry ingredients, stirring until a firm dough forms, about 2-3 minutes.

Fold in 1/4 cup of finely chopped cranberries until evenly distributed.

On a lightly floured surface, roll out the dough to approximately 1/4-inch thickness.

Cut the rolled-out dough into 5-inch long and 1/2-inch wide strips.

Bake the strips in the preheated oven for 25-30 minutes, until firm and golden brown.

Turn off the oven and leave the treats inside for an additional 10-15 minutes to cool.

Store the treats in an airtight container at room temperature for up to a week.
