I have been making these cookies since they debuted in November 2001, and they have become a family tradition and THE MOST REQUESTED cookie recipe in my arsenal of recipes! I bake triple quantities every year for Christmas, and my 4 children request them for their birthdays, too. Follow the baking instructions exactly; overcooking the cookies will not yield a tender, chewy cookie. Be sure to refrigerate BOTH the baked cookies and the filling until well-chilled prior to frosting and stacking. This prevents any melting and mess, and you'll have beautiful little sandwiches every time. Enjoy!

I like this recipe, though it's pretty rich. When I next make them, I plan on adding more sugar, lightening up the filling and baking for longer so that the cookies are more wafer-like. WARNING: This recipe is only good for true chocolate lovers! ;-)

I really loved the cookie, they spread and baked nicley. I added a little of milk chocolate chips to the cookie. The filling was different and bitter so I changed it up and it turned out wonderful; a wonderful contrast to the cookie (sorry Martha but I think this filling is pretty good). I added 1 cup confectioner sugar, 4 tablespoons of milk, and 6 ounces of cream cheese and doubled amount of malt. It was much lighter in color and all flavors really came through!!!!

Ok, to the person who said her filling was dark and not like the picture, make sure you finish reading the directions. After the filling chills in fridge, you have to beat it for 3 mins. That is when it gets lighter in color and fluffier in texture. I am chilling mine now so the filling will set. They are good cookies! This is only the 2nd time I baked with malted milk powder. It's definitely a different taste. The fillling is light and not sweet at all. Definitely a nice recipe!

These were the hit of our United Way bake sale yesterday and all my colleagues at Strong National Museum of Play want this recipe!

I am having a hard time finding malt milk mix. I found Ovaltine, but it has alot of sugar in it. Any thoughts on aking your own?

Best chocolate cookies EVER! I didn't have creme fraiche, so I just used regular sour cream,

Best EVER chocolate cookies! I used whole milk for the creme fraiche and half and half since I didn't have either and they still turned out great!

What about the vanilla in the cookie recipe--it's not mentioned in the directions. It is mentioned in the directions for making the filling.

These were SO worth it! The special ingredients and the time....the batch was a little large for this house though. Also, as the batter sat at room temp as I was baking, the last few cookies didn't look as good. Too flat. So I would put it in the fridge between batches.
