It's a great, easy to make alternative to more elaborate cakes or pastries that could be served with coffee. It makes quite a large cake, but no worries here, it keeps for 4 to 5 days under a cake dome.
For the cake:
1 1/2 cups all purpose flour
3/4 tsp baking powder
1/2 tsp baking soda
pinch of salt
5 oz unsalted butter, at room temperature
5 1/2 oz superfine sugar
2 large eggs
1 tsp vanilla extract
1 cup sour cream
1/4 cup toasted pecans
3 oz coarsely chopped bittersweet chocolate
3 tbs light brown sugar
1 1/2 tbs natural cocoa powder
Preheat oven to 350F. Generously butter a 9-inch bundt pan.
Make the filling: In a food processor, pulse pecans, sugar, chocolate and cocoa to combine and chop the pecans and chocolate.
For the cake: In a bowl whisk the flour, baking soda, baking powder and salt. In another bowl beat the butter and sugar until smooth and creamy. Beat in eggs, one at a time until well blended. Blend in vanilla.
Next alternate adding the dry ingredients and the sour cream, beginning and ending with the dry ingredients.
Spoon half the batter into the bundt pan. Smooth with the back of a spoon, spreading out evenly. Sprinkle over the filling, then layer on the rest of the batter. Run a large wooden skewer around the pan for a few times to get the desired marbled effect. Smooth the top again.
Bake until golden brown and the wooden skewer inserted comes out clean, about 45 to 55 minutes.
Transfer to a wire rack and let cool before removing from the pan.
