All you need is a regular box of cake mix. Follow the directions on the back adding the eggs, oil, etc... If you have a large class you may want to use two boxes and double the recipe. You will need an electric skillet and one Dixie cup for each child. You need to purchase the Dixie cups with the raised bottom. Spray each cup with pam and add a tablespoon of water to the bottom of each cup. Then add about 2-3 tablespoons of batter to each cup. Place the cups in the electric skillet on 350 degrees for about 15 minutes covered. It may take a bit longer. Use the toothpick check to be sure. Let cool. Let your children decorate their cakes with icing and sprinkles. Everyone will enjoy their hedgehog cakes!
