1. Preheat the oven to 350F. Line a muffin tin with 8 muffin liners and set aside.
2. In a large mixing bowl, add your dry ingredients and mix well. Add your peanut butter and unsweetened applesauce and mix until fully combined. Fold through your chocolate chips.
3. Divide the batter amongst the muffin liners and bake for 10-12 minutes, or until a skewer comes out mostly clean.
4. Remove the muffins from the oven and allow them to cool for 5 minutes, before transferring to a wire rack to cool completely.
