Chocolate Coma Sandwich Cookies

Nick, my college sophomore, was home for a weekend visit.  Miss Lambeau wasn’t doing well…and we wanted him to have some time with her as we knew we’d have to say goodbye to her soon. Intensely decadent chocolate desserts are a must when one of the boys comes home…whether for dinner or an overnight stay. Calling these Chocolate Coma Sandwich cookies  “decadent” would be an understatement. Let me explain why…

This recipe, found in Sunset, utilized 12 ounces of melted chocolate plus 1 1/2 cups chocolate chips, then another 6 ounces in the dreamy chocolate ganache. Nick snatched up a couple of these babies before I had a chance to fill them. He must have missed the standard food blogger memo about family members needing to check on the status of desserts before diving in.

Anyhow, the point is, he was found in a chocolate coma after eating two of these cookies without the filling. There were a lot of moans and groans of pleasure when these were actually sampled in sandwich form. I offered to cut them in half, but the chocoholics would not have that. They’re gluttons for punishment!

Tips for Making Sandwich Cookies:

  • Use a cookie disher to scoop out cookie dough onto the baking sheet. This will ensure the cookies are of a similar size when baked and will be easier to match up a top and bottom cookie.
  • Before you start filling the cookies, pair up similarly sized and shaped cookies. Doing this ahead of time will help prevent having only a larger and smaller cookie left at the end! 
  • Let the cookies cool before filling. Also, let ganache cool until it’s a spreadable consistency.
  • I liked piping on the ganache with a star tip for a pretty swirl visible between the cookies. But using a knife or offset spatula to smooth on the filling works well, too.
  • PRO-Tip: If you like a more intense chocolate flavor, substitute bittersweet chocolate for the semisweet. You can also up the espresso powder to 1 tablespoon for a bigger mocha boost.

Dreamy chocolate overload cookies filled with chocolate ganache


For cookies:

  • 10 ounces semisweet chocolate, chopped
  • 3 ounces unsweetened chocolate, chopped
  • 1/4 cup butter, cut into chunks
  • 3 eggs, at room temperature
  • 1 cup plus 2 tablespoons sugar
  • 1 teasspoon instant espresso powder
  • 2 teaspoons vanilla extract
  • 6 tablespoons flour
  • 3/4 teaspoon baking powder
  • 1/4 teaspoon kosher salt
  • 1 1/2 cups semisweet chocolate chips

For ganache:

  • 6 ounces semisweet chocolate, chopped
  • 3/4 cup whipping cream


  1. Make cookies: Put chopped chocolates and butter in a microwave safe bowl and microwave at 30 with 30 second increments, stopping and stirring each time till melted and smooth; let cool slightly.
  2. Whisk eggs, sugar, espresso powder, and vanilla into chocolate mixture. In another bowl, stir together flour, baking powder, and salt. Stir dry ingredients into chocolate mixture until evenly mixed, then stir in chocolate chips. Cover dough and chill until firm enough to hold its shape, about an hour.
  3. Meanwhile, make ganache: Put chopped chocolate and cream in a microwave safe bowl and microwave at 30 second intervals, till melted and smooth, then let cool. Cover and chill, stirring occasionally, until firm enough to spread, about 2 hours. If ganache becomes too firm to spread, you may zap it in the microwave for a few seconds to soften.
  4. Preheat oven to 350°. Line 2 large baking sheets with parchment paper. Scoop out 2 tablespoons of dough, roll into rounds, then place on prepared sheets onto sheets about 1 inch apart. Press dough to flatten to about a ½ inch thickness. Bake about 10 minutes, till tops lose their wet look, but don't overbake. Let cookies cool on sheets on racks.
  5. Spread flat sides of half of cookies with ganache and top with remaining cookies.
