I have made them. They wen't over like a lead balloon! LOL I crumbled the cake and mixed with frosting. I used a smaller sized cookie scoop to semi-form the balls. Then I rolled them in my hands and chilled. They looked nothing like the ones on Pinterest - and I am a decent baker and decorator. Not professional by any means, but I do OK.

I have made the Oreo ones - those are much better. Toss a bag of oreos in a food processor with a block of cream cheese. Form the balls and chill. Dip in melted (GOOD) chocolate. I used Ghiradelli melts. Everyone loved those.

Tried the mini donut maker, similar concept, but with no stick. We tried a regular cake mix and used less liquid than called for, almost like batter for thick pancakes. Worked well they were uniform in size when we used a large tablespoon to fill each cavity. Yesterday we tried a chewy brownie mix, and found it just a bit too thick and had to add a tablespoon of liquid. Came out well. Dipped them in cream cheese icing just as they were cooling off. Strange that they do not put any kind of instructions in the boxes from the manufacturer. It would help. Each time I have used it I only make a batch, in my case 7, and store the rest in a tupperware container in the fridge. Quick dessert or snack when you want one NOW. I wonder if you froze your pops for a few minutes maybe ten to fifteen, before adding sticks that they might grab on better, and would be easier to dip or put toppings on them?

ps chocolate seems to burn fast so keep an eye on it when cooking in those little machines.

Yes,I have made cake balls-the older method,no machine-mine turned out great-have been given for bday parties,etc.My Grandkids love them.
