1 cup sour cream
3/4 cup oil
1/3 cup honey
1/3 cup packed brown sugar
1 Tbsp cinnamon or pumpkin spice
2 cup powdered sugar
1/3 cup milk
1 tsp vanilla
Preheat oven to 350. Lightly spray a 9x13-inch pan with cooking spray.
In a large bowl, mix together cake mix, sour cream, oil and eggs on low speed of an electric mixer for 1 minute. Increase speed to medium and beat 2 minutes more. Pour into prepared pan.
Drizzle honey on top of batter, then sprinkle on the brown sugar and cinnamon or pumpkin spice. With a knife, swirl topping to blend.
Bake 38-40 minutes. Whisk together powdered sugar, milk and vanilla. Pour over warm cake. Allow cake to cool at least 20 minutes before cutting.
