After seeing cake balls on TV and being unable to find them for purchase I decided to make them myself. This book appeared to be the best choice I could find on Amazon so I ordered it and started making the recipes. The basic recipes for cake and icings to use to make the balls are good and easy to follow (I haven't tried using commercial cake mixes or canned icings). So far I've been very successful using only the information from this book.
Using the basic recipes and instructions you can make a variety of different cake balls by experimentation. I have also used the recipes exactly as given for a number of balls and have never been disappointed. I do tend to add more icing to the crumbled cake for making the balls, but that's a matter of taste. Although I can't compare this book to others (I've only used this one book) I don't think you could go wrong with this excellent, to-the-point book. It has excellent photos of the finished cakeballs along with a lot of practical advice on each step of making the cakeballs.
I have personally tried the following recipes, all with great success: Chocolate Toffee, Chocolate Butterscotch, Chocolate Pistachio, Triple Chocolate, Cinnamon Streusel, Irish Cream, Dreamsicle, Tres Leches. I created my own creations using brownie mix and Andes Mints. When you dip the frozen cookie balls in your coating (I use melted chips, mostly) the coating hardens very quickly leading to nice, smooth coatings that can be placed on your plate with almost no disturbance to the beautiful coating. Don't hesitate trying the drizzling of the cakeballs for a nice, professional-looking finish. I add little items to the top to code the types of balls, such as a small piece of Andes Mints, a chip of chocolate, a sprinkling of colored sugar, etc. Some material doesn't make good coating material, such as peanut butter chips (too stiff). Some experimentation is advised, but you can certainly with just a little practice and experimentation create fabulous tasting and appearing cake balls. I'll try to add a picture of some of my creations.
