I have the recipe - Here it is - Coffee Coffee Cake with Espresso Glaze from The Gourmet Cookbook
Coffee Coffee Cake with Espresso Glaze
"The recipe, from "The Gourmet Cookbook" (Houghton Mifflin, 2004) can be doubled and baked in a 10-inch bundt pan. Increase baking time to about an hour."
For the cake
2 cups all purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1-1/2 sticks (12 tablespoons) unsalted butter, softened
1 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
1 cup sour cream
2 tablespoons instant espresso powder, dissolved in 1 tablespoon hot water
For the glaze
1-1/2 teaspoons instant espresso powder
2 to 3 tablespoons strong brewed coffee
3/4 cup confectioners sugar, sifted
Make the cake: Put a rack in the middle of oven and preheat oven to 350 F. Generously butter an 8-inch (6 cup) bundt pan. Whisk together flour, baking powder, baking soda, and salt in a bowl. Combine butter and sugar in a large bowl and beat with an electric mixer at medium speed until pale and fluffy, about 2 minutes. Add eggs one at a time, beating well after each addition, then beat in vanilla. Add flour mixture alternately with sour cream, beginning and ending with flour mixture and mixing
until just incorporated. Transfer about one third of batter to a small bowl. Add espresso mixture and stir until well combined. Spoon half of plain batter into bundt pan and spread evenly. Top with coffee batter, spreading it evenly, and cover with remaining plain batter, spreading it evenly. Bake until cake is golden and a wooden pick or skewer inserted in the center comes out clean, 55 to 60 minutes. Cool in pan on rack for 30 minutes, then invert onto rack to cool completely. Make the Glaze: Stir together espresso powder and 2 tablespoons coffee in bowl until powder is dissolved. Add confectioners' sugar and stir until well combined. If glaze is not pourable, thin with remaining coffee, as necessary. Pour glaze over coffee cake and let cake stand until glaze is set, about 10 minutes, before serving.
