1Preheat your oven to 180°C (350°F) and line a baking tray with parchment paper.
In a medium bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, and salt. Set aside.
In a large bowl, cream the unsalted butter, granulated sugar, and brown sugar together until light and fluffy.
Beat in the egg and vanilla extract until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the dark chocolate chips.
Scoop tablespoon-sized portions of dough onto the prepared baking tray, spacing them about 2 inches apart.
Bake for 10-12 minutes, or until the edges are set but the centers are still soft.
Allow the brownie cookie bites to cool on the tray for 5 minutes before transferring to a wire rack to cool completely.
Serve and enjoy your delicious Brownie Cookie Bites!
