Ingredients
Cake:
- ½ cup all-purpose flour
- ¼ cup unsweetened cocoa, sifted
- ¼ cup cornstarch
- ¼ teaspoon salt
- 6 tablespoons unsalted butter
- 2 ounces unsweetened chocolate
- 1 teaspoon vanilla extract
- 6 large eggs, at room temperature
- 1 cup sugar
Filling:
- ¾ cup heavy cream
- ¾ cup sugar
- 2 teaspoons instant espresso powder or instant coffee
- 1 cup sour cream
Glaze:
- 4 ounces semisweet chocolate
- ½ cup heavy cream
Cooking Instructions
Cake:
- Heat oven to 350 degrees F. Cover 15 x 10-inch jelly roll pan (sided cookie sheet) with parchment or waxed paper. Sift cocoa evenly over tea towel; reserve.
- In bowl whisk flour, cocoa, cornstarch and salt to combine.
- Melt butter and unsweetened chocolate in microwave 1 minute. Stir to combine. If not completely melted, continue to heat in 30 seconds intervals until completely melted. Stir in vanilla.
- In mixer whip eggs and sugar 4 minutes or until mixture is a light lemon color and it falls in a ribbon-candy shape when beater is lifted.
- Fold dry ingredients into eggs just to combine. Fold melted butter mixture into eggs just to combine.
- Pour batter into prepared pan. Smooth batter evenly. Bake 20 minutes, or until cake just begins to pull away from sides of the pan and a toothpick inserted in the middle comes out clean.
- Run knife around sides of cake. Immediately invert cake onto prepared tea towel. Carefully remove parchment paper. Dust cake with cocoa. From long side roll up cake to form a log. Let cool completely.
Filling:
- Whip cream with sugar until soft peaks form. Dissolve espresso in 1 tablespoon hot water. Add coffee to cream. Whip cream until stiff peaks form. Fold in sour cream; reserve.
Glaze
- In microwave-proof bowl melt chocolate in the heavy cream on high 1 minute. Stir to combine. If chocolate is not melted, repeat in 30 minute intervals. Stir smooth. Let cool until it’s a spreadable consistency.
Putting Cake Together
- Carefully unroll cake. Starting ½-inch from the edges, spread filling over cake. Carefully roll cake back into log. Pour glaze to evenly cover log. At a diagonal, slice off a 2-inch piece of the cake. Adhere it to the side of the log. Serve immediately, or chill until ready to serve and bring to room temperature before serving.
Substitution(s)
- Bittersweet or semisweet chocolate can be used in the cake instead of the unsweetened chocolate
Make-Ahead
- Filling can be made up to a day ahead, stored in the refrigerator and whipped lightly to bring it back to stiff peaks.
- Frosting can be made up to 3 days ahead and gently microwaved just to melt
