4 ounces bittersweet chocolate, chopped into small pieces
4 ounces semi-sweet chocolate, chopped into small pieces
3/4 cup unsalted butter, cut into pieces
4 eggs
1/2 cup sugar
1/4 cup all-purpose flour
1 tablespoon unsweetened cocoa powder
2 teaspoons pure vanilla extract
1 teaspoon instant espresso powder or 2 teaspoons instant coffee granules
1/2 teaspoon salt
Black Cherry Sauce (see recipe below)
Whipped cream
Shaved Chocolate
Preheat oven to 375 F. Liberally spray six (6-ounce) ramekins with nonstick spray. In a small saucepan over low heat melt the chocolate and butter, stirring often to prevent burning. Remove from heat and cool.
In a large mixing bowl, beat eggs and sugar with electric hand mixer until "ribbon" stage, approximately 7 minutes. At that stage, it will be pale yellow and look like lightly whipped cream.
Add flour, cocoa powder, vanilla extract, espresso powder, and salt. Beat the batter for 2 additional minutes; add the melted chocolate mixture and beat another 5 minutes. (The batter needs a lot of beating. This incorporates air, lightening the cake's texture.)
Scoop the batter into the prepared ramekins, approximately 3/4 cup of batter in each ramekin. NOTE: At this point, the cakes can be refrigerated and then baked later.
When ready to bake, place the ramekins on a baking sheet and bake 15 to 17 minutes or until puffed and mostly dry on top around edges. NOTE: It's critical to bake these cakes for the right amount of time. Otherwise, they'll either be way too "molten," or end up as brownies. Oven temperatures vary, so check the cakes after 15 minutes. If they're really moist on top, bake one minutes and check again.
Remove cakes from oven and let rest 3 minutes (it's okay if they sink a little).
To unmold, place serving plate on top of ramekin and invert. Carefully remove ramekin, tapping lightly on the plate to loosen cake. Serve the molten cakes warm with warm Black Cherry Sauce, whipped cream, and shaved chocolate.
