Dreaming about Dream Coffee Cake

Ever since Marge Green served this coffee cake at a Beta Sigma Phi meeting, I have been dreaming about this tender cake full of walnuts, cinnamon and spice. It's also a dream to make as it can me mixed up and assembled quickly. Thank you to Marge for sharing.
The recipe instructions were for a 13x9" baking pan. I used two 8" square pans. I also used a homemade cake mix.

Dream Coffee Cake  Makes one 13x9" cake or two 8x8"cakes / Serves 20
Cake
1 (18 oz.) yellow cake mix or use a homemade cake mix
1 cap vegetable oil
4 eggs
1 cup sour cream
Nut & Spice Mixture
3/4 cup granulated sugar
1 1/2 teaspoons ground cinnamon
1 1/2 cups chopped walnuts

1. Preheat oven to 350°. Grease or spray a 13x9" baking pan or two 8x8" pans.
2. Cake: Combine cake mix, vegetable il, eggs and sour cream in a large bowl. Beat 2 minutes with a mixer at low speed, scraping sides of bowl frequently.
   
3. Nut & Spice Misture: Mix sugar, cinnamon and walnuts in a medium bowl.
4. Spread half the batter in the 13x9"pan. Sprinkle half the walnut mixture over top. Repeat with remaining batter and walnut mixture. (Adjust the amounts accordingly if using two 8x8" pans.)
   
   
   
   
   
   
   
5. Bake the 13x9" cake for 40 minutes (about 30 for the two 8x8" cakes) or until a wooden toothpick instead in the center comes out clean.
   
6. Serve warm or freeze and serve later.
