Step 1

Prep: Preheat oven to 350°F degrees and generously grease a 9x13-inch baking pan.

Step 2

Make the batter: In a mixing bowl, add the butter and sugar and mix well until light and creamy. To it add the eggs, vanilla extract, sour cream and mix well until combined. In another bowl, mix the flour with the baking soda, baking powder and salt. Add the flour mixture to the mixer and mix everything well.

Step 3

Mix the streusel: In a small bowl mix the chopped pecans with the brown sugar and cinnamon.

Step 4

Assemble and bake: Place half the batter in the baking pan. Pour half the pecan mixture over the batter. Repeat with remaining batter and pecan crumble. Bake for 45 to 55 minutes. To test for doneness, insert a toothpick in the center of the cake, it should come out clean when baked through.

Step 5

Make glaze: Add the icing sugar and milk to a small bowl and whisk until smooth, add more milk if wanting a thinner consistency.

Step 6

Finish the cake: Let the cake cool in the pan for about 15 minutes then drizzle with glaze, cut into slices and serve.
