No candy pieces here. These thumbprint cookies are filled with chocolate ganache.
1 cup (1/2 lb.) butter, at room temperature
1/4 cup firmly packed brown sugar
1/2 cup granulated sugar
2 large egg yolks
1 teaspoon vanilla
2 cups all-purpose flour
1/2 teaspoon baking powder
1/4 teaspoon salt
About 1/3 cup turbinado sugar (see notes)
Chocolate ganache (recipe follows)
How to Make It
In a bowl, with a mixer on high speed, beat butter, brown sugar, and granulated sugar until smooth. Beat in egg yolks and vanilla until well blended, scraping sides of bowl as needed.
In a small bowl, mix flour, baking powder, and salt. With mixer on low speed, beat flour mixture into butter mixture until well blended. Cover bowl with plastic wrap and chill until dough is firm but pliable, about 30 minutes.
Place about 1/3 cup turbinado sugar in a shallow bowl. Shape dough into 1-inch balls and roll to coat in turbinado sugar. Place 1 inch apart on buttered 12- by 15-inch baking sheets. Press your thumb into the center of each cookie to make a 1/2-inch-deep imprint.
Bake cookies in a 325° regular or convection oven until lightly browned, 10 to 12 minutes. If baking more than one sheet at a time in one oven, switch positions halfway through baking. Transfer cookies to a rack to cool completely (if indentations have disappeared, make them again while cookies are warm).
Carefully fill each indentation with about 1/2 tablespoon chocolate ganache. Let cool until ganache is shiny and firm to the touch, about 1 hour (or chill for about 30 minutes).
Chocolate ganache: In a heatproof bowl set over (but not touching) barely simmering water in a pan, occasionally stir 6 ounces chopped bittersweet or semisweet chocolate, 2 tablespoons whipping cream, 1 tablespoon corn syrup, and 1 tablespoon butter until chocolate is melted and mixture is smooth. Remove from heat and let cool until thick but not firm, about 15 minutes. Makes about 1 1/4 cups.
Nutritional analysis per cookie.
Turbinado sugar is a light golden brown, large-crystal sugar, sometimes labeled "raw sugar" or "Demerara sugar." It's available in some well-stocked supermarkets and natural-foods stores. If you can't find it, substitute additional granulated sugar. These cookies are best the day they are filled, but you can make both the cookies and the filling up to 3 days ahead. Store cookies airtight at room temperature; chill ganache airtight. Melt ganache over hot water and cool (as described in recipe, following) before using.
I made these this Christmas and we gave them as gifts....they are very easy and they are amazing to taste ....I used Scharffen Berger semisweet 62% cacao fine artisan dark chocolate.....my 6 year daughter helped....we made 5 of these batches. They are outstanding!
I only made the genache because I have a STELLAR thumbprint recipe that I have been making FOREVER! I usually put strained raspberry or apricot jam in the middle so the genache is such a treat! Use pie weights to hold down the thumb print (or a few dried beans. Gently flick them out with a fork after cooking). These take time, but they are worth it! I roll mine in egg white then in ground pecans rather than sugar. AMAZING!
Although the cookie itself is good, it is really only a vehicle for delivery of the yummy chocolate ganache. I had to make another indentation into the cookies after they came out of the oven, because they flattened out too much. I'm not sure what went wrong.
