Ingredients
Method
Prepare the Bowl and Cake Base
- Line a 2 1/2-quart bowl with plastic wrap, making sure there is enough overhang to fold over the top later.
- Slice the sponge cake in half horizontally and fit one half into the bottom of the bowl.
- If using pound cake, place the slices together so they cover the base well.
- Cut part of the second half into strips and press them up the sides of the bowl.
- Sprinkle the cake with the coffee liqueur to soak it evenly.
Make the Italian Pastry Cream
- Whisk the egg yolks and sugar in a medium pot while off the heat.
- Whisk in the flour gradually to keep the mixture smooth.
- Boil the milk and stir in the vanilla.
- Slowly pour the hot milk into the yolk mixture, whisking to avoid curdling.
- Set over medium heat and stir constantly until boiling; cook for 3 to 4 minutes, then remove from heat.
Add Chocolate and Whipped Cream
- Melt the 4 ounces of semisweet chocolate.
- Whip 1 1/4 cups heavy cream with espresso powder to stiff peaks.
- Fold Grand Marnier or Cointreau, grated dark chocolate, and whipped coffee cream into the cooled pastry cream until smooth.
- Spoon two-thirds of the filling into the lined bowl, leaving a hollow in the center.
- Stir the melted chocolate into the remaining filling and add to the hollow.
Close, Chill, and Unmold
- Cover the top with leftover cake pieces and sprinkle with more liqueur.
- Fold the plastic wrap over the top and refrigerate for at least 6 hours, or overnight if possible.
- Before serving, whip the remaining cup heavy cream with coffee powder and sugar to stiff peaks.
- Peel back the plastic wrap, invert onto a plate, and lift off the bowl.
Decorate and Serve
- Swirl coffee whipped cream over the dome for a soft look.
- Finish with grated chocolate or chocolate curls.
- For cleanest slices, chill for about 1 more hour before serving.
Notes
This dessert pairs well with coffee, fresh berries, and can be served alongside biscotti or almond cookies.
