DIRECTIONS
- Preheat oven to 350 degrees F (175 degrees C). Grease a 9×13-inch baking dish. Cut 9 caramels in half.
- Beat brownie mix, vegetable oil, water, and eggs together in a bowl until batter is well-combined. Pour batter into prepared baking dish. Place caramel halves in 3 rows of 6 in the brownie batter so that there will be a caramel half in the center of each brownie.
- Bake in the preheated oven until a toothpick inserted into the center comes out almost clean, 25 to 30 minutes.
- Melt remaining caramels, butter, and milk together in a microwave-safe glass or ceramic bowl in 30-second intervals, stirring after each melting, for 1 to 3 minutes (depending on your microwave). Pour caramel mixture over warm brownies and top with pretzels, chocolate chips, and toffee bits. Cool completely before cutting into squares.
