Preheat your oven to 350°F (175°C) and grease two round cake pans. In a large mixing bowl, combine your chocolate cake mix, eggs, water, and vegetable oil. Beat the batter on medium speed for about 2 minutes until smooth. Pour evenly into the prepared pans and bake for 25–30 minutes or until a toothpick comes out clean. Allow to cool.

Prepare the filling by whisking together the chocolate pudding mix and milk as per package instructions until thickened, about 2 minutes. In another bowl, beat softened cream cheese with powdered sugar until smooth, then gently fold in the pudding mixture.

Once cooled, remove cakes from pans. Place one layer on a serving platter and spread half of the filling. Add the second layer on top, pressing gently. Use the remaining filling to cover the top and sides.

Sprinkle crushed Oreos liberally over the cake to mimic dirt. Press the cookie crumbs gently into the filling for better adherence.

Melt candy melts and pour into a piping bag. Create gravestones or designs on parchment paper; allow to set for about 10 minutes and then place on the cake.

Add gummy worms over the dirt and position candy eyes to peek out. Tuck fresh mint leaves around for color, ensuring decoration is well-distributed.

Slice your cake for serving, chill until served, and present on a festive table. Your guests will be thrilled with both the look and taste of this delightful dessert!
