Where’s the full recipe - why can I only see the ingredients?

Always check the publication for a full list of ingredients. An Eat Your Books index lists the main ingredients and does not include 'store-cupboard ingredients' (salt, pepper, oil, flour, etc.) - unless called for in significant quantity.

Notes about this recipe

    Can substitute bittersweet chocolate chips for semisweet chocolate chips, and M&Ms for candy-coated chocolate chips.

    Made for MIL's church potluck. Subbed sprinkles. These were really dark and rich. With the ganache, I felt the chocolate intensity was WAY too much and disliked the cookies after 1 bite despite being a chocolate lover. Maybe the first trimester is affecting my tastebuds, though. Much better next day, and all disappeared from the dessert table.

    Wow. Super easy to pull together and the cookies, which tasted like super nice chewy, fudgy brownies could be enjoyed without the topping if you really want a quick treat. I'm thinking of playing with the flavor of the topping to go for a more grown up flavor... And cut the richness a bit. But terrific as is.
