I just finished making some Honey Bran muffins in the cake pop maker. It was so fast and easy.
I had half a package of the mix left. I used 1/2 of that (1/4 of the whole package) and poured it into a ziplock bag. I then added 1/2 cup of water and sealed the bag and smoshed it to mix. Cut a corner off the ziplock bag and poured into the cake pop maker like it was cake mix.
I did spray the maker with cooking spray before each batch.
