Bill's Favorite Pumpkin Crumb Cake

My boyfriend, Bill, cannot get enough of this cake, which I would venture to say is his all-time favorite! I finally decided to post it for all the pumpkin-lovers out there! It is very easy to make, and is a nice alternative on your Thanksgiving or holiday dessert table.

• Ready In: 1 hr
• Serves: 8-10

Ingredients

• 1 (18 1/4ounce) package  yellow cake mix
• 1  egg, beaten
• 1⁄2 cup butter, melted
• 1 (15 ounce) can pumpkin puree
• 3  eggs, beaten

• 1⁄2 cup white sugar

Directions

1. Preheat oven to 350 degrees . Spray 9x13 inch baking pan with non-stick cooking spray.
2. Measure out and set aside 1 cup of the dry cake mix.
3. In a large mixing bowl, combine the rest of the dry cake mix with 1 egg and 1/2 cup melted butter. Mix well, and then pat with fingers into prepared pan to form a crust layer.
4. In a large bowl, mix together the pumpkin puree with the 3 eggs, 1/2 cup white sugar, brown sugar, and cinnamon. Pour over crust.
5. In a small bowl, combine the reserved 1 cup cake mix, 1/2 cup sugar, and 3 tablespoons softened butter. Crumble over pumpkin filling to make crumb topping. Sprinkle walnuts evenly over the top.
6. Bake in preheated oven for about 40 to 45 minutes until set and lightly browned.
