Spooky Halloween Whoopie Pies are soft chocolate cakes sandwiched with bright orange frosting, decorated with sprinkles, candy eyes, and playful Halloween details. They’re festive, fun, and perfect for parties or trick-or-treat night.
Preheat the oven to 350°F. In a large mixing bowl, whisk together the cake mix, water, vegetable oil, eggs, and pudding mix. Beat on medium speed for about 2 minutes until smooth.
Scoop the batter into rounds on lined baking sheets—18 for larger Whoopie Pies or 36 for smaller ones—keeping them uniform in size.
Bake for 7–10 minutes, until the tops spring back when gently pressed. Transfer to a cooling rack and let cool completely.
Tint the vanilla icing with orange food coloring gel, mixing until the color is bright and streak-free.
Spread or pipe a thick layer of frosting onto the flat side of one cake, then top with another to form a sandwich. Repeat with the rest.
Finish with edible black glitter, candy eyes, or black licorice legs for spiders. Use powdered sugar stencils for extra festive designs.
