Prepare the cookie dough:

Cream together softened butter, brown sugar, and granulated sugar until smooth. Add vanilla extract and mix well. Gradually incorporate heat-treated flour and salt, mixing until the dough forms. Stir in mini chocolate chips. Roll dough into 1-inch balls and freeze for 30 minutes.

Prepare the brownie base:

Preheat the oven as per brownie mix instructions. Prepare brownie batter by mixing the brownie mix with eggs, oil, and water. Stir in optional mini chocolate chips. Grease or line a 9x9-inch baking dish and pour in brownie batter, spreading evenly.

Assemble the brownie bombs:

Take frozen cookie dough balls and scoop small portions of brownie batter, flattening them in your hand. Place a cookie dough ball in the center of the brownie batter, and wrap it around to form a ball. Repeat until all dough and batter are used. Place the brownie bombs close together in the dish.

Bake the brownie bombs:

Bake according to the package instructions, checking for doneness after 25 minutes. Bake for an additional 5-10 minutes if needed. The toothpick should come out with a few moist crumbs when inserted.

Coat with chocolate:

In a microwave-safe bowl, melt semi-sweet chocolate chips with vegetable oil in 30-second intervals, stirring until smooth. Dip each brownie bomb into the melted chocolate and place them on a parchment-lined tray to set.

Let the chocolate set:

Allow chocolate to firm up at room temperature or speed up the process by refrigerating for 30 minutes.
