Anyone can make this – this simple Halloween cake uses boxed yellow cake mix after all! Save your elegant desserts for other occasions – all we need is an easy-to-make universally-liked cake base to decorate, so the yellow cake for the mix fits the bill perfectly!  Of course, you can use any made-from-scratch cake recipe you like – once the cake is ready, decorate away!

Easy Halloween Cake Design Ideas

To start decorating this Halloween cake, spread the top of the baked cake with white frosting.  You can use the simple sugar glaze in the recipe below, white frosting from a can or homemade vanilla buttercream frosting.  Any frosting will do as long as it’s white in color, as we want the design to stand out against the white frosting.

Next, use the squeezable tube of store-bought black frosting to draw the spider web.  Just copy the spiderweb design from my picture and keep it simple! After you have the spiderweb, draw the spiders – body and six legs.  You can use black frosting to make the spiders or as another alternative, use the black prunes for the spider body.  Use the red or white frosting from a tube to make the eyes for the spiders.

Use the marshmallows to make the ghosts – simply use scissors to cut the marshmallows into ghosts shapes and then use black and red frosting for the eyes.

To make tombstones, use graham crackers covered with frosting :) Spread the black frosting all over the graham cracker, write R.I.P. in red or white tube frosting, then put those crackers in the spooky cake so they stand like the Halloween tombstones.

Use the red frosting to draw swirls of blood around the cake (or on the tray with the cake as shown on my photo). What I’ve done is spread the red frosting on the white cutting board that holds the cake and then used fingernails to make swirly lines in the “blood” frosting.

There are no rules – just use this easy Halloween cake design ideas as your inspiration and be creative! Have a spook-tacular and tasty Halloween!  Please check back after Halloween for ideas on what to do with leftover Halloween candy!

Recipe type: Dessert
Cuisine: American
Serves: 12 servings
  • 1 box yellow cake mix
  • 3 eggs
  • 1 cup water
  • ⅓ cup vegetable oil
  • 1 cup powdered sugar
  • 1 tbsp milk
  • 1 tsp vanilla extract
  • 3 tbsp butter, melted
For decorations
  • Graham crackers
  • White frosting from a tube
  • Black frosting from a tube
  • Red frosting from a tube
  • Marshmallows
  1. Preheat the oven to 350F.
  2. Spray a non-stick 13x9 inch baking pan with a non-stick cooking spray.
  3. Mix the yellow cake mix, eggs, water and vegetable oil in a large bowl until blended. Pour into a baking pan, put in the oven and bake for 35 minutes, or until the toothpick inserted in the center comes out clean.
  4. Make the glaze: in bowl mix the melted butter, vanilla, milk and powdered sugar until smooth.
  5. Spread the glaze over the top of the cake. Let the cake cool completely before decorating.
  6. To decorate the Halloween cake, first draw the spider web lines by squeezing the tube of black frosting. Then make the spider shapes by squeezing out the black frosting from the tube (as an alternative, you can use the black prunes to make the body of the spider). Make the eyes of the spiders with red and white frosting dots.
  7. Cover the graham crackers with black frosting, write R.I.P on them with red frosting, then insert the crackers into the top of the cake (just press them into the cake so they remain in an upright position).
  8. Cut the ghost shapes out of marshmallows using scissors. Draw the eyes using the red tube frosting. Put the marshmallow ghosts on the cake.
  9. Use the red frosting to draw bloody swirls around the cake (or on the cake tray outside of the cake).
