Ingredients
Streusel
- 1 1/2 c firmly packed light brown sugar
- 1 tbsp. ground cinnamon
- 6 tbsp. salted butter, diced
- 1 1/2 c coarsely chopped pecans
- 1 c semisweet chocolate chips
Cake
- 3 c all-purpose flour
- 1 1/2 tsp. baking soda
- 1 1/2 tsp. baking powder
- 1 1/3 c granulated sugar
- 3/4 c (1½ sticks) salted butter, at room temperature
- 3 large eggs, at room temperature
- 1 1/2 tsp. freshly grated orange peel
- 1 1/2 tsp. pure vanilla extract
- 1 1/2 c ½ cups sour cream
- freshly squeezed orange juice
- confectioners’ sugar, as topping
Instructions
Streusel
- In a medium bowl, whisk the brown sugar and cinnamon to blend.
- Add in the butter and rub it with your fingertips until the mixture holds together in small, moist clumps.
- Mix in the pecans and chocolate chips.
- The streusel can be made up to 3 days ahead. Cover and refrigerate until ready to use.
Cake
- Preheat the oven to 350°F and prepare a 9x13-inch baking pan with baking spray or butter and flour.
- Sift the flour, baking soda, and baking powder into a medium bowl.
- Using an electric mixer or a stand mixer, beat the granulated sugar and butter until blended and smooth.
- Beat in the eggs, one at a time, mixing well after each addition. Add in the grated orange peel and vanilla extract.
- Mix in the sifted flour mixture in four additions alternating with the sour cream, beginning and ending with the flour mixture.
- Stir in the orange juice and combine well.
- Spread half of the batter in the prepared pan. Sprinkle with half of the streusel.
- Drop the remaining batter over the streusel by heaping tablespoonfuls. Carefully spread the batter to make an even layer.
- Sprinkle with the remaining streusel.
- Bake the cake for 30 minutes.
- After the first 30 minutes, lay a sheet of foil loosely over the pan to keep the topping from browning too quickly. Continue baking until a knife or toothpick inserted into the center of the cake comes out clean, about 35 minutes longer. Remove the foil.
- Cool the cake in the pan on a rack for 20 minutes. Dust the top with confectioners’ sugar; serve warm or at room temperature.
