Pecan Sour Cream Coffee Cake

Crumb topping:

• 1 1/2 C pecans, finely chopped
• 1/3 C sugar
• 1/3 C packed brown sugar
• 1 tsp cinnamon
• 1/8 tsp salt
• 3 T melted butter

Cake:

• 1 7/8 C flour
• 1/2 tsp salt
• 1 tsp baking powder
• 3/4 tsp baking soda
• 1/2 C butter
• 1 C sugar
• 2 eggs
• 1 1/2 tsp vanilla
• 1 C sour cream or creme fraiche

Directions:

1. Preheat oven to 350 degrees F.  Butter an 8" by 10" baking dish.
2. Mix pecans, 1/3 C sugar, brown sugar, cinnamon, salt, and melted butter thoroughly in a mixing bowl until all components are coated with butter, 3 to 4 minutes.
3. In a separate bowl, whisk together flour, salt, baking powder, and baking soda.
4. In another bowl, mix together butter and 1 C sugar until well blended.  Add 1 egg and whisk until mixture is smooth, 2 to 3 minutes.  Whisk in second egg until thoroughly incorporated.  Add vanilla and sour cream; whisk together.  Add flour mixture to wet ingredients; whisk until flour disappears (do not over mix).
5. Spread one half of the batter evenly into the bottom of the prepared baking dish.  Scatter one half of the crumb mixture evenly over the top of the batter.  Top with the rest of the batter and spread carefully to evenly distribute, trying not to disturb the crumbs.  Top with the rest of the crumb mixture.  Very gently press crumbs into batter.  Bake in preheated oven until a skewer comes out clean, 30 to 35 minutes.  Let cool slightly before serving.
