Experiment 1 was made with Manichevitz Brownie Mix, because it was on sale for 50c at the Scratch And Dent. Lemme just say, this is the most amazing brownie mix ever. It's rich and uber-fudgy and even when it's cooked into charcoal briquettes, it's amazingly chocolatey. I should have just eaten it with a spoon, because, as you can see, the mix did not like the Puff Pan, no matter what the poorly-worded flier says about being able to use any mix. They burned before they were cooked enough to flip, the little flip-stick didn't work, and I had to flip them with a spoon, which scratched the pan and managed to knock half the batter out of each puff. but they were still tasty.
Experiment 2 went much better. I decided brownies were too ambitious, and I scaled it back to the pancakes that were in the title-- just a normal bisquick pancake mix. I turned down the heat one notch, oiled it with butter instead of spray, and I didn't fill the little wells as high, and voila! Almost-Perfect Pancake Puffs!
I want to try it with eggs, and with little pellets of potatoes stuffed with cheese, and maybe with cookie dough, and I have a muffin mix I want to try, too. I'll keep you posted.
The main problem, once I figured out how not to make charcoal, is that they don't cook very fast; there's only seven at a time, and by the time numbers 8 through 14 are done, numbers 1 through 7 are either nibbled away or stone cold. So I wouldn't recommend this for anything requiring a hot meal, but pancakes are reheatable, and other baked goods are just as tasty at room temp, and I think it'll be okay.
