If you’ve ever been to Thomas Keller’s Bouchon Bakery, chances are you’ve seen or eaten one of his famous TKOs, a.k.a. Thomas Keller Oreos (below).
Like most of Keller’s food, his take on the classic Oreo is a textbook example of refined simplicity — white chocolate ganache sandwiched between two chocolate shortbread cookies. They’re one of our favorite cookies, and I thought it would be fun to make them for Christmas presents.

The Las Vegas NBC affiliate, KVBC, posted the TKO recipe on their Web site, which I thought was odd, but then I remembered that Keller opened a Bouchon Bakery in The Venetian a few years ago. We lengthened the the baking time from 8 minutes to 20 minutes after an unsuccessful first batch and the 20-minute baking time worked out much better. We also made a seasonal, mint-flavored TKO by adding some mint extract, peppermint extract and green food coloring to the ganache.
CHOCOLATE SHORTBREAD COOKIES
1/4 tsp baking soda
1 pound (4 sticks) butter
18 oz (by weight) all purpose flour
12 oz (by weight) sugar
1 teaspoon Salt
6 oz Cocoa powder
DIRECTIONS
1. Preheat oven to 325 degrees.
2. Cream butter with paddle on mixer until smooth, then add sugar and mix until combined, scraping down the mixing bowl.
3. Sift dry ingredients. Add dry ingredients to mixing bowl and work dough until just combines. (it should look kind of like brown sand)
4. Roll dough between two sheets of parchment paper until 1/4 inch thick. Cut each cookie with scalloped cutter.
5. Bake at 325 F for approximately 20 minutes
6. Let cookies cool and then sandwich together with the following filling:
GANACHE FILLING
4 oz white chocolate (cut into small pieces or buy white chocolate chips)
1 oz heavy cream
1/8 teaspoon mint extract (optional, for mint filling)
1/8 teaspoon peppermint extract (optional, for mint filling)
green food coloring (optional, for mint filling)
DIRECTIONS
Bring cream to a boil and pour over chocolate, then mix until emulsified. Allow ganache to set up for at least an hour before using. Ganache should be spreadable, kind of like peanut butter.
To make the mint ganache, add mint extracts to ganache along with food coloring just before placing between the chocolate shortbread cookies.
The white chocolate ganache is perishable, so if you’re making these, make sure their consumed within three days. This can be difficult, because these cookies are really rich and it’s sometimes hard to eat just one. Enjoy!
