I actually pulled this week's TWD off! I really wanted to make these, but I didn't have a Madeleine pan and didn't want to buy one because I would never use it again. Enter the P&Q. Chocolatechic (who has a great blog) posted about using a muffin pan. Great! I have those!
I used a standard size muffin tin. I halved the recipe and only made 6. I loved the shiny ganache on top. These were so chocolatey (never a bad thing) and yummy. I think I would like something besides the marshmallow fluff in these- maybe a buttercream or something?
I also cut the baking time to about 9 minutes for the size and number of my cookies. Thanks to Margot for the great pick!
