Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Cook the chicken breasts for 15-20 minutes until tender, then shred and set aside.

In a bowl, cream together butter and brown sugar until fluffy. Mix in maple syrup, then add flour and baking soda until combined.

Gently fold in shredded chicken into the dough.

Scoop tablespoon-sized portions onto the prepared sheet and bake for 10-12 minutes, until golden around the edges.

Allow to cool slightly before dusting with powdered sugar.
