Below is a review and photo from blogger Never Turn Down a Cupcake:
This Girl Scout cookie-based flavor is a chocolate cake with crushed Thin Mint cookies baked inside, topped with a chocolate ganache and decorated with fondant Girl Scout decorations.And these are the cupcakes we tried: the mint cookies & creme, for sale on Saturdays, which is so so good in my and my friend's opinion (it tastes like mint chocolate chip ice cream!) and the chocolate², which is "Valrhona chocolate cupcake with a whipped Callebaut chocolate frosting topped with a fondant flower," was rich and wonderful. I ate half of it and felt like I'd gotten more than my share of very rich, thick chocolate frosting. I recommend them both!
Even though I'm not a fan of mint chocolate, this was really rich and tasted mostly of chocolate which I liked, haha. The little bits of cookie inside were interesting and added a nice texture to both the cake and the frosting.
And while I'm catching up on my blogging, I also tried pumpkin spice and banana chocolate. Both were very good. The pumpkin spice's official description is "Pumpkin spice cupcake with a maple-infused cream cheese frosting topped with a fondant maple leaf" and I can tell you that the maple frosting was unique and very good. I wasn't sure if I'd like it but it had this kick to it that made it amazing. The banana frosting was good too, though I liked the pumpkin spice better.
