Preheat your oven to 350°F (175°C). Prepare the chocolate cupcake mix according to the package instructions, combining with eggs and water or milk. Pour into lined cupcake tins and bake for 18-20 minutes until a toothpick comes out clean. Allow to cool completely.

While cupcakes cool, whip up fudge frosting if making from scratch: beat softened butter, gradually add sifted cocoa powder and powdered sugar until combined. Add milk for creamy consistency or set store-bought frosting aside.

Frost the cooled cupcakes generously with the rich fudge frosting using a spatula or piping bag for design.

Place one Keebler Fudge Stripes cookie on top of each frosted cupcake. Attach a piece of candy corn or chocolate kiss on top with a dab of frosting to complete the witch hats.

Optional: Sprinkle Halloween-themed sprinkles around the base of the cookies for added flair. Arrange on a platter for serving.
