Not what I thought

I was super excited to try oit the Duncan Hines perfect size for one. I tried the sunrise blueberry muffin and I wasnt impressed. After putting it in the microwave for the time allotted I noticed that the top of it seems a little rubbery. I added a few extra ingredients to it and it definitely didnt make it taste any better. My kids will eat anything but they werent pleased with it either. This was definitely not what I expected it to be.
