Line an 8” baking pan with parchment paper, leaving a little bit of overhang on the sides.

Pour brownie batter into the prepared pan and smooth it into an even layer. Bake according to recipe instructions.

Allow brownies to cool completely. Pull up on the parchment paper and transfer the brownies to a flat surface. Cut the brownies into rectangles (4 x 3 to make 12 rectangle brownies).

Mix all of the frosting ingredients together in a bowl. Mix for 2 minutes until light and fluffy. Adjust thickness with powdered sugar or milk as needed, and mix in green food coloring.

Use the black decorating gel to write R-I-P on the top of each milano cookie. Optionally cut the bottom edge of the cookies to make them shorter.

Press each cookie into the top of the brownie.

Spoon a little green frosting near the headstone and place a candy pumpkin on top.
