Here's another version of cake balls designed especially for Halloween.  These make delightful little “truffles” which you can pipe a contrasting color of candy over the top for a pretty, artistic presentation.  You can get creative as you want -- you can make cake balls that resemble Jack-o-Lanterns, eyeballs, Ninja Turtles or even flowers. 
 
Ingredients
· 1 box Cake Mix (Red Velvet Or yellow about 18 oz)
· 1 can Frosting (store bought 12 oz)
· 1 bag Melting Chocolate (12 oz  any color or combination of colors)
· 1 bag Lollipop Sticks
· Various Tubes Gel Icing (any colors)

Preparation Instructions

Just prepare the cake according to the directions on the package, and bake it in a 9 x 13-inch pan. Cover the cake with a dishtowel and allow to cool completely.

Once the cake has cooled, begin gently crumbling the cake. Place sections of the cake into a large bowl, 1/4 of the cake at a time. When you’re finished, you should have a bunch of very fine cake crumbs.

Use two forks to work the icing into the cake. Keep working until the icing is no longer visible. Even if you use white icing with devil’s food, the white will eventually blend in entirely.

Next, roll the mixture into balls—make them about walnut size – a small ice cream scoop could help with this.

This is important: pop ‘em in the freezer, uncovered, for at least an hour. The cake balls need to be very firm before coating them.

When the cake balls are nice and firm, go ahead and prepare a double boiler.

Dump the melting chocolate pieces into the bowl of the double boiler. Stir occasionally until the chocolate is totally melted and smooth and set aside.

Insert a stick sideways into each ball (paying attention to the flat part on the bottom). Now, you can either roll the ball in the chocolate, or spoon it over the top—whatever’s easier for you.

Be sure to thoroughly coat the bottom of the ball where it meets the stick.

Lay them back down onto waxed or parchment paper, paying attention to the flat part (get it against the parchment again.)

Now decorate and get creative as you want!
