Brown Sugar Walnut Coffee Cake

Brown Sugar and Walnut Coffee Cake

For the filing:
7 tablespoons butter, melted
1 cup brown sugar
1 cup walnuts, chopped
1 teaspoon cinnamon

For the batter:
2 cups flour
1 teaspoon baking soda
1 teaspoon baking powder
1/4 teaspoon salt
3/4 cup granulated (white) sugar
1 stick butter, softened
3 eggs
1 cup sour cream

Preheat oven to 325F. Butter and dust with flour a bundt cake pan (I use spray).

In a medium bowl, mix all the ingredients for the filling. In a separate bowl, mix flour, baking soda, baking powder and salt.

With an electric mixer, cream butter and sugar until white and fluffy. Add one egg at a time, beating after each addition. At low speed, add 1/3 of the flour mixture, then 1/2 of the sour cream, 1/3 of the flour mixture, then the remaining sour cream and flour, mixing until just combined.

Pour half of the batter in the pan, spread half the filling on top, add the rest of the batter, then the rest of the topping. Bake approximately 1 hour, until the tester comes out clean. Let sit in the pan for about 5 minutes, then invert on a rack (use caution) and cool completely.
