I got the idea while looking at a few of my favourite blogs and as luck would have it I hadn't visited Brown Paper Packages in a while and that's when I saw Kierste's post. I then jumped on Pinterest and added it to my 'favourite receipes board'. The recipe was really easy to follow the only thing I needed to do was convert a few of the ingredient requirements because its an American recipe. I also waited until as late as possible to make the cake because I didn't want the popcorn going stale.
So having followed Kierste's instructions there is only one thing I'd change about the entire process. The recipe asks you to melt the marshmallows with the butter, then stir it through the popcorn and lollies. I would recommend reducing the amount of butter to a knob of butter so that it just coats the pot and then the marshmallow shouldn't stick. My other piece of advise is to work quickly as the marshmallow needs to stay soft while its been mixed together.
I was able to feed 30 people with this cake, I didn't give large portions because of the sweetness of the marshmallows. Each child loved that they got a lolly and popcorn all in one.
