Making truffles is much easier than I expected, and I've tried several recipes lately, but this is the best one.
1 box red velvet cake mix (cook as directed on box for 13 X 9 cake)
1 can cream cheese frosting (16 oz.)
1 package chocolate bark (regular or white chocolate)
After cake is cooked, crumble into large bowl. Mix thoroughly with 1 can cream cheese frosting. You can use your hands for this, if you don't mind getting messy. It'll be easier if you do it while the cake is still somewhat warm. Then, put the mixture in the fridge and let it cool for an hour or so.
Roll mixture into quarter size balls and lay on cookie sheet. (Should make 45-50.) Chill for another hour, at least. Overnight wouldn't be the worst thing.
Melt chocolate in microwave, stopping to stir each minute until it's completely melted. Roll balls in chocolate and lay on wax paper until firm. (Use a spoon to dip and roll in chocolate and then tap off extra.)
