Mom's Sour Cream Coffee Cake

Ingredients

1/2 lb butter, softened
1 c sugar
2 eggs, beaten
8 oz sour cream
2 c all purpose flour
1 tsp baking powder
1 tsp baking soda
1/2 tsp salt
1 tsp vanilla

TOPPING AND MIDDLE OF CAKE
1/2 c chopped walnuts
1/4 c sugar
1 tsp ground cinnamon

NOTE: I ALWAYS DOUBLE THE TOPPING AND PUT 1/2 IN THE MIDDLE AND 1/2 ON TOP OF CAKE. WE LOVE IT !

**CAKE CAN BE GLUTEN FREE/WHEAT FREE BY SWAPPING GF FLOUR FOR REGULAR FLOUR. THE CAKE WILL BE DELICIOUS.

Directions

1. Preheat oven to 350 degrees. Cream butter, and sugar in a large bowl. Add eggs, sour cream and vanilla, beating on medium speed until well blended.
2. In another bowl, mix flour, baking powder, baking soda and salt together. Add gradually to creamed mixture, beating after each addition.
3. Have walnuts, sugar and cinnamon mixed together. Butter a 9-inch spring form pan. Put 1/2 the batter into pan and sprinkle 1/2 the cinnamon mixture over batter. Add remaining batter and sprinkle with the rest of the cinnamon mixture. **batter will be thick, so I dollop it over the cinnamon layer of cake, and gently blend it together with the back of a spoon, then sprinkle cinnamon over top of cake.
4. Bake for 45-60 minutes, or until a toothpick comes out clean.
