These brookies cookies are like pretzel brownie bites in the form of a cookie - a perfect sweet and salty combo! If you are craving something super chocolatey, these cookies are the answer.
Preheat oven to 350F and line 2 baking sheets with parchment paper.
Chop up the pretzels and dark chocolate into small pieces and set aside for later.
In a medium bowl, combine flour, cocoa powder, baking powder, and baking soda. Set aside.
In the bowl of a standing mixer with the paddle attachment or a handheld mixer, combine butter and sugars, mixing until smooth.
Add in the egg and vanilla extract, and beat until just combined (do not over-mix!).
Mix in the dry ingredients until a thick dough forms. Toss in the dark chocolate until combined.
Use a medium cookie scoop or spoon to make 1.5 tablespoon sized balls and place them on the baking sheet.
Press about 5 pretzel pieces into each cookie. They don't need to be pressed all the way into the cookies, just enough so that they don't fall out. Sprinkle each cookie with a little bit of sea salt before putting them in the oven (optional).
Bake the cookies for 6-8 minutes. Remove from the oven and leave them on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely. Enjoy!
