If only I'd written it down!

I made something yummy today. It's similar to a rice crispie treat, but not. There was some melted butter, marshmallows, and peanut butter mixed together. Instead of rice crispies I used cheerios. I put that in the pan, then sprinkled chocolate chips on top. I didn't really make enough (it was too thin in the pan), so I made it again, and put the second 'batch' on top of the first batch. So I have these peanut buttery marshmallow cheerio crispies with a layer of chocolate in the middle.

I just wonder if I'll ever be able to make them again?
