Start by preheating your oven according to the brownie mix directions. Grease your casserole dish or baking pan, or line it with parchment paper for easy removal later.

In a large mixing bowl, combine the brownie mix with the oil, water, and eggs listed on the box. Mix it all together until the batter is smooth and glossy.

Pour half of the brownie batter into the greased pan and spread it evenly. Break your Hershey Symphony Bar into pieces and layer them across the top. Then pour the remaining brownie batter over the candy and gently spread it to cover everything.

Bake the brownies following the package directions until they’re rich, fudgy, and your kitchen smells like pure chocolate heaven. Let them cool completely before cutting—trust me, this step makes all the difference.

Once the brownies are cool, carefully lift them out of the pan if you used parchment paper. Press your bat-shaped cookie cutter into the brownies and lift out each little bat. If needed, use a small spatula to help loosen them without breaking off any wings.

This is where they really come to life! Add a tiny dot of gel frosting where each eye will go, then gently press on the edible candy eyes. Suddenly, you’ve got a tray full of the cutest brownie bats staring back at you.

Arrange your bats on a platter and serve them at room temperature. They’ll stay fresh in an airtight container for a few days—if they last that long!
