These are super simple and don't take much time to put together. Ben was able to do all of the work himself, which matters a lot to him.
We put one cup of chocolate chips in a glass bowl and microwaved that for 30 seconds at a time, stirring in between until melted. Then we added in a cup of the Fiber One. There is nothing exact about this "recipe"--we added a little more cereal at a time and stirred it in until the it was coated but there wasn't a ton of chocolate left in the bottom of the bowl.
Then we put a couple of spoonfuls of the chocolate/cereal mixture into cupcake liners to give them a basic nest shape and left them to cool. Reese's eggs and jelly beans added the final touch and they were done. See? Easy. And totally adjustable...this made about 12 nests, but we could have just as easily made a smaller batch so I didn't have to figure out where to store the extras. (I put each of the leftovers into a plastic sandwich bag and popped them in the freezer--they have held up fine.)
