We recently did jello in the cups and it worked out great. One 3 oz. jello filled about 6 cups. The kids love picking out their flavor for lunch.
This is what the batter looks like after the egg whites are folded in. In case you never beaten egg whites, a stiff peak is just that-when you lift the beaters from the beaten egg whites a stiff peak will form and it will not fall. Sorry I don't have a picture.
Here they are cooking. The trick to these is getting the right temperature. When you have the right temp. they cook very quickly, and I just flip them over with skewers. When they need to be flipped, they pull a little from the sides and when the bubbles pop, the indentation stays.
Oh the possibilities are endless. These are great because when you pour the batter in the pan, you can fill them with a tsp. of anything: chocolate chips, jams, fruits(apples, blueberries, bananas etc.), pie fillings, sausage etc. I also like to leave them plain and have fun with the toppings like below.
These are some of my favorites
