Chocolate Grand Marnier Sour Cream Coffee Cake |
Preheat oven to 350 degrees F. Grease and flour a 2 inch deep 9 inch baking pan; A spring form pan also works well.
Sift together and set aside:
- 1 3/4 cups flour
- 1 1/2 tsp baking powder
Cream together well:
- 1 cup butter
- 1 cup sugar
Beat in, one at a time:
- 3 eggs
Beat in:
- 2 tsp vanilla
- 1 cup sour cream
Fold in the dry ingredients and divide the batter in half. To one half fold in:
- zest of 1/2 an orange, finely minced
To the other half fold in:
- 1/4 cup cocoa
- 2 tbsp milk
Drop the batter by large spoonfuls randomly into the prepared pan, alternating between the chocolate and orange batters. Swirl slightly with the handle of a wooden spoon if you like for a more marbled effect.
Bake for 35-40 minutes or until a wooden toothpick inserted in the center comes out clean. Let the cake rest in the pan for about 15 minutes before poking the entire surface of the cake with a wooden skewer. Pour or brush on:
- 3 ounces Grand Marnier liqueur or other orange liqueur
Remove cake, right side up to a wire rack to cool completely.
When cool, top with truffle glaze.
For the truffle glaze melt together in a double boiler:
- 1 cup dark chocolate chips (I used 50% cocoa chips)
- 1 tbsp butter
- 3 tbsp whipping cream
When melted you can whisk in a small splash of Grand Marnier if you like. Spread over cooled cake and top with toasted chopped hazelnuts.
