01 - Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
02 - In a medium skillet over medium heat, cook the maple sausage until browned and cooked through, breaking it apart as it cooks for approximately 5–7 minutes. Drain any excess fat and allow it to cool slightly.
03 - In a medium bowl, whisk together the all-purpose flour, old-fashioned oats, baking soda, ground cinnamon, and salt.
04 - In a large mixing bowl, cream together the softened unsalted butter and packed light brown sugar until the mixture is light and fluffy. Incorporate the pure maple syrup, large egg, and vanilla extract until thoroughly combined.
05 - Gradually add the combined dry ingredients to the wet mixture, stirring until just incorporated. Avoid overmixing.
06 - Gently fold in the cooked maple sausage, shredded sharp cheddar cheese, and chopped pecans (if using) into the dough.
07 - Drop heaping tablespoons of the dough onto the prepared baking sheet, ensuring each cookie is spaced approximately 2 inches apart.
08 - Bake for 14–16 minutes, or until the edges achieve a golden brown hue and the centers are set.
09 - Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
