Ingredients
For the Cake:
- 15.25 oz box fudge marble cake mix
- 1 cup water
- 1/3 cup oil
- 3 eggs
For the Jello Filling:
- 6 oz package orange jello
- 1 cup boiling water
- 1 cup cold water
For the Frosting:
- 1/2 cup butter, softened
- 3 1/2 cups powdered sugar
- 1/3 cup baking cocoa
- 1/4 cup milk
- 1 tsp vanilla extract
- Halloween sprinkles for decoration
Instructions
- Prepare the Cake: Follow the instructions on the fudge marble cake mix box to prepare the batter using water, oil, and eggs. Pour the batter into a 9 x 13 inch pan and bake for 25 minutes or until a toothpick comes out clean. Allow the cake to cool completely in the pan.
- Poke Holes in the Cake: Using a straw or wooden skewer, poke holes all over the top surface of the cooled cake. These holes will allow the jello filling to seep in and set inside the cake for a moist texture.
- Make the Jello Mixture: In a small saucepan, bring 1 cup of water to a boil. Stir in the orange jello powder until fully dissolved. Remove from heat and stir in 1 cup of cold water to cool the mixture slightly.
- Fill the Cake: Pour the prepared jello mixture evenly over the cake in the pan, allowing it to fill the holes and soak through. Cover and refrigerate the cake for at least 2 hours, or until the jello is fully set.
- Prepare the Frosting: In the bowl of a stand mixer, beat the softened butter until creamy. Gradually add powdered sugar, baking cocoa, milk, and vanilla extract. Continue to beat until the frosting is smooth and spreadable, adding extra milk by tablespoonfuls if needed to reach desired consistency.
- Frost and Decorate: Once the jello has set, spread the chocolate frosting evenly over the top of the cake. Finish by sprinkling Halloween-themed sprinkles on top for a festive look.
Notes
- Ensure the cake is completely cooled before poking holes to prevent breakage.
- The jello filling should be cooled slightly before pouring to avoid melting the cake layers.
- Refrigerate the cake for at least 2 hours to allow the jello to set properly.
- You can substitute orange jello with other flavors for different looks and tastes.
- Store any leftovers covered in the refrigerator for up to 3 days.
