Banana Chocolate Chip Cookies

0 Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. Set aside.
1 In a medium mixing bowl, mash the banana with a fork until smooth. Set aside.
2 In a large bowl, whisk together the melted butter and brown sugar until smooth and creamy. Add the mashed banana, egg, and vanilla extract. Mix until fully incorporated.
3 In a separate bowl, whisk together the flour, ground cinnamon, baking soda, and salt.
4 Gradually add the dry ingredients into the wet mixture. Stir until just combined, being careful not to overmix.
5 Gently fold in the chocolate chips and chopped chocolate bar until evenly distributed.
6 Using a medium cookie scoop or tablespoon, drop the dough onto the prepared baking sheets, spacing them about 2 inches apart.
7 Bake the cookies for 10-12 minutes, or until the edges are set and the centers look slightly underbaked.
8 Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
