Amazing Pecan Coffee Cake

Step 1
Preheat oven to 350 degrees F (175 degrees C). Line a 9x13 inch pan with aluminum foil, and lightly grease with vegetable oil or cooking spray. Sift together the flour, baking powder, and salt; set aside.

Step 2
In a large bowl, cream the butter until light and fluffy. Gradually beat in sour cream, then beat in sugar. Beat in the eggs one at a time, then stir in the vanilla. By hand, fold in the flour mixture, mixing just until incorporated. Spread batter into prepared pan.

Step 3
To make the Pecan Topping: In a medium bowl, mix together brown sugar, pecans and cinnamon. Stir in melted butter until crumbly. Sprinkle over cake batter in pan.

Step 4
Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let cool in pan for 10 minutes, then turn out onto a wire rack, and remove foil.
