Preheat oven to 350 degrees.

Fill your cupcake pan with cupcake liners and set aside.

Combine the cake mix, eggs, water and oil until slightly lumpy.

Fill cupcake liners 2/3 full.

Put in the oven and bake for 18-21 minutes.

Check for doneness by inserting a toothpick into the center of a cupcake, it should come out clean. If they are not done, check again every three minutes until they are done.

Remove from the oven and allow to cool.

Transfer to a cooling rack and allow to cool completely before frosting.

Remove the orange creme from 16 halloween Oreos.

Using a standing mixer combine the butter, powdered sugar, heavy whipping cream, vanilla, Oreo creme and mix on medium speed until combined and smooth.

Scoop 1 cup of frosting into the piping bag and set aside.

Line a cookie sheet with parchment paper.

Carefully separate the Oreos, use the side that has no Oreo creme.

Using a heat safe bowl, melt the chocolate wafers until smooth. You can do this in the microwave in 30 second increments. Stir and repeat until melted.

Dip half of cookie into the chocolate.

Place onto the cookie sheet and sprinkle some halloween sprinkles.

Allow to dry.

Using the orange frosting, scoop a small amount into the ice cream scooper (can also use a spoon) and place onto the top of the cupcake and spread slightly into a thick disk.

Pour the Halloween sprinkles into a deep bowl and dip the top of the cupcake frosting into the sprinkles.

Using the piping bag, pipe the frosting into the center.

Carefully place the decorated Oreo onto the side of the frosting.

Sprinkle some more halloween sprinkles on top.

Serve Enjoy!
