Preheat your oven and prepare the brownie batter according to the package instructions. Line a 9×13-inch baking pan with parchment paper and pour in the prepared batter. Bake as directed, then allow the brownies to cool completely.

In a large bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy. Add milk and vanilla extract, mixing until combined. Gradually fold in flour and salt, mixing until a soft dough forms. Stir in mini chocolate chips. Scoop tablespoon-sized portions of dough, roll into balls, and place on a parchment-lined baking sheet. Refrigerate for at least 30 minutes.

Cut cooled brownies into squares slightly larger than the cookie dough balls. Flatten each brownie square, place a chilled cookie dough ball in the center, and wrap the brownie around the dough ball. Seal any seams and roll gently to form a smooth ball. Repeat until all are used. Freeze assembled balls for about 15 minutes to firm.

Melt semisweet chocolate chips (and vegetable oil, if using) in a microwave-safe bowl in 30-second intervals, stirring until smooth. Dip each brownie bomb into the melted chocolate, allowing excess to drip off. Place coated bombs on a parchment-lined baking sheet. Optionally, sprinkle mini chocolate chips or decorative sprinkles before the chocolate sets. Let the coating set completely.
