It's time for me to start planning and practicing for this year's Holiday Dessert Contest. This year I wanted to make something a little less...architectural than my last year's winning entry. (2.5 foot tall croquembouche decorated w/spun sugar elements to resemble a transmission tower). My current idea, inspired by my office breakfasts of late, is to make several GIANT Girl Scout Cookies.

Here's what I'm looking for:

Thin Mint Cookie Cake: I'm thinking of a sort of crunchy, cookie brownie for this. Any tips or recipes for that sort of thing? What about the best way to incorporate mint flavor into a baked item? Any good recipes for a thin milk chocolate shell?

Samoa Cookie Cake: I want that chocolate-covered vanilla cookie bottom, with a really chewy, dense coconut caramel top. This may be difficult, because I'll need a 4 inch "chewy" layer. Maybe the secret is to make the coconut element more to scale? Like, instead of flakes, I make coconut bars, and toss that in caramel? Any ideas?

Do-Si-Do Cookie Cake: The final challenge. I want to make two giant crunchy peanut butter cookies, and layer them with a peanut butter cream. Is it possible to make a giant peanut butter cookie that's cooked long enough to make it crispy w/out burning it? Ideas welcome.
