1. Prepare the Dough  

– In a medium bowl, whisk together flour, baking powder, baking soda, salt, and ground cinnamon. Set aside.

– In a large mixing bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy. Add the egg and vanilla extract, mixing until combined.

2. Combine Ingredients

– Gradually add the dry ingredients to the wet ingredients, mixing just until combined. If using cinnamon chips or nuts, fold them into the dough.

3. Chill the Dough 

– Cover the dough and refrigerate for at least 30 minutes. This helps the cookies maintain their shape while baking.

4. Preheat and Prepare 

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

– In a small bowl, mix the cinnamon and sugar for the coating.

5. Shape and Coat 

– Roll the dough into 1-inch balls. Roll each ball in the cinnamon-sugar mixture until fully coated. Place them on the prepared baking sheet, about 2 inches apart.

6. Bake  

– Bake for 10-12 minutes or until the edges are set and slightly golden. The centers should still be soft.

– Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
