Easy Cinnamon Coffee Cake Recipe

First preheat the oven to a temperature of 350°. Then grease a 10 inch tube pan lightly. Once that is done, take a large mixing bowl and cream together the butter with 2 cups of sugar. When it turns fluffy, add the eggs and vanilla one at a time taking care to beat the mixture well after each egg is added.
Next mix the baking powder, baking soda and flour. Now alternatively add the egg mixture and the sour cream and beat. While doing so, beat only enough to keep the batter smooth. Now combine the remaining sugar with cinnamon and walnuts.
Once the above steps are complete; spoon 1/3 of the batter into the prepared pan. Then over it sprinkle 1/3 of the walnut mixture. Ensure you repeat this layer 2 more times. Put this into the oven and bake it at 350° for 70 minutes. When it’s done, let it cool in the pan for 10 minutes after which remove the pan and let the cinnamon coffee cake continue to cool on a wire rack.
