These cookies are heaven! The gooey center will make you melt, and if you can bring yourself to share them, you'll become the talk of the town. This recipe is an original creation, and now officially my favorite cookie ever. The ganache will have to refrigerate overnight, and it's best to let the cookie dough chill overnight as well. The ganache recipe will make 1 cup of filling, but you can make larger batches if desired, it keeps nearly forever in the fridge, and will save a lot of time for future batches of cookies. I have edited the recipe to include 1ts of baking soda in the dough to help with the rise, per the review's suggestion. Yield varies on size of cookie. This recipe isn't fast, but it's worth it!
