Place your peanut butter in a piping bag or large Zip lock bag. Cut the tip off and pipe quarter sized discs onto a wax paper lined plate. Place in the freezer while you make the dough.

In a large bowl, combine the brownie mix, eggs, oil and flour until well mixed and it forms a dough. Scoop a chunk of cookie dough using a 2 inch scoop. Flatten it and lift one piece of peanut butter and place in the center. Turn all of the edges of dough over the peanut butter until it's completely coated. Keep the cookie dough semi-flattened. Place on the wax lined plate. Once all are done, place in the freezer.

Preheat your oven to 350 degrees. Once it reaches temperature, remove the cookie dough from the freezer and lay on a parchment lined baking sheet 2 inches apart. Allow them to fully cool.

Melt 2 tablespoons of peanut butter and transfer to a ziploc bag. Cut a very small piece off the tip and drizzle the cookies. Top with flaky sea salt if you'd like!
