Preheat oven to 350° Grease bottom and sides of a 13” x 9” pan.
Cake
1 yellow cake mix
2 large eggs
1 ¼ cup water
1/3 cup oil
4 oz. sour cream
1 tsp. vanilla
½ tsp. ground cardamom
1 Tbsp. cinnamon
Add all ingredients to a large mixing bowl. Mix with electric mixer on low for 30 seconds, then on medium for 2 minutes. Pour batter into greased pan.
Topping
6 Tbsp. melted butter
½ cup chopped walnuts
1 cup oats
1 cup packed brown sugar
Melt stick of butter (or margarine) in large microwave safe bowl. Add walnuts, oats and brown sugar. Mix to make a crumb topping for cake. Sprinkle evenly over top of cake. Bake in 350° oven for 35-40 minutes or until a toothpick inserted in cake comes out clean.
Ideas for variations:
· Pecans could be substituted for walnuts
· Make a Cinnamon Apple Walnut Coffee Cake by:
o Substituting 1/3 cup of applesauce for the oil used in the cake recipe
o Adding a shredded apple to the topping
* Disclaimer- I have not tried this recipe with any of the variations…yet, but thinking about it is making me hungry.
