1 cup unsalted butter, softened
1 cup granulated sugar
1 cup brown sugar, packed
4 large eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
1/2 cup cocoa powder
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup sour cream
1 cup pecans, chopped
1/2 cup chocolate chips
1/2 cup heavy cream
1/2 cup dark chocolate, chopped
Extra pecans for garnish
Preheat the oven to 350°F (175°C) and grease a loaf pan.
In a large bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition, then mix in the vanilla extract.
In a separate bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, alternating with the sour cream, beginning and ending with the dry ingredients. Mix until just combined.
Fold in the chopped pecans and chocolate chips.
Pour the batter into the prepared loaf pan and bake for 60-70 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
For the ganache, heat the heavy cream in a small saucepan over medium heat until just simmering. Remove from heat and add the chopped dark chocolate. Let sit for 5 minutes, then stir until smooth.
Pour the ganache over the cooled cake and garnish with extra pecans.
