Ingredients

For the Pumpkin Cake Base

• 1 box Yellow or Spice Cake Mix (standard 15.25 oz size)
• 1 (15 oz) can 100% Pure Pumpkin Puree (NOT pie filling)
• ⅓ cup Vegetable Oil
• 3 large Eggs
• 1 tsp Vanilla Extract

For the Cinnamon-Sugar Swirl

• ½ cup (1 stick) Unsalted Butter, melted
• 1 cup Light Brown Sugar, packed
• 2 Tbsp Ground Cinnamon
• ½ cup Chopped Pecans or Walnuts (optional)

For the Vanilla Glaze

• 2 cups Powdered Sugar, sifted
• 4 Tbsp Milk (or heavy cream)
• 1 tsp Vanilla Extract

Instructions (Step-by-Step)

1. Prep Cake Base: Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan. In a large bowl, combine the cake mix, pumpkin puree, vegetable oil, eggs, and vanilla extract. Beat with an electric mixer on medium speed for 2 minutes until smooth and well-combined.
2. Add Cake Batter: Pour about two-thirds of the pumpkin cake batter into the prepared pan and spread it into an even layer.
3. Create the Swirl Filling: In a separate medium bowl, whisk together the melted butter, brown sugar, ground cinnamon, and chopped nuts (if using).
4. Layer the Swirl: Drizzle the cinnamon-sugar swirl mixture evenly over the cake batter in the pan. Use a knife or skewer to gently swirl the mixture into the cake batter, creating a beautiful pumpkin swirl cake pattern.
5. Finish Top Layer: Gently spoon the remaining one-third of the cake batter over the swirl filling. You don’t need to spread it perfectly—it will even out as it bakes.
6. Bake and Cool: Bake for 40–45 minutes, or until a toothpick inserted into the center comes out mostly clean. Let the cake cool in the pan for at least 15 minutes before glazing.
7. Make Glaze: While the cake cools, whisk together the sifted powdered sugar, milk, and vanilla extract until smooth. The glaze should be thick but pourable.
8. Glaze and Serve: Pour the vanilla glaze over the warm cake, spreading it gently to cover the top. Let the glaze set for 10–15 minutes before slicing and serving warm.

Storage and Make-Ahead Tips

• Storage: Store cooled cake covered tightly at room temperature for up to 3 days, or in the refrigerator for up to 5 days.
• Freezing: The unglazed cake freezes well! Once cooled, wrap the entire cake tightly in plastic wrap and foil and freeze for up to 3 months. Thaw overnight and add the fresh glaze before serving.

Expert Baking Tips

• Pumpkin for Moisture: The pumpkin puree replaces most of the moisture traditionally provided by milk and water in a standard boxed cake mix recipe. This ensures the cake is dense, moist, and incredibly soft.
• The Swirl Consistency: Ensure the butter in the swirl mixture is melted—not just softened. This helps the sugar dissolve slightly and creates that signature gooey, sticky texture after baking.
• Don’t Overbake: The cake is done when the edges pull slightly away from the pan and a toothpick comes out with moist crumbs (not wet batter). Overbaking will dry out the cake.
• Sift the Sugar: Sifting the powdered sugar before making the glaze is a small step that prevents lumps and guarantees a perfectly smooth, professional-looking drizzle.

Variations

• Spice Cake: Use a spice cake mix instead of yellow cake mix for an extra deep, autumnal flavor profile.
• Cream Cheese Glaze: For an extra decadent topping, use a cream cheese glaze (cream cheese, butter, powdered sugar) instead of the simple vanilla glaze.
• Chocolate Swirl: For a double-chocolate surprise, replace 1 tablespoon of cinnamon in the swirl mixture with 1 tablespoon of unsweetened cocoa powder.
• Gluten-Free: Easily substitute the standard cake mix with a gluten-free yellow or spice cake mix.

Serving Suggestions

Serve this warm, spiced pumpkin honey bun cake with simple complements:

• Topping: A dollop of fresh whipped cream or a scoop of vanilla ice cream.
• Drinks: A hot mug of coffee, spiced chai tea, or a cold glass of milk.
• Breakfast: Serve slightly warmed slices for an indulgent breakfast treat!

Frequently Asked Questions

Q: Can I use pumpkin pie filling instead of pumpkin puree? A: No, you must use 100% pure pumpkin puree. Pumpkin pie filling contains sugar and spices, which will throw off the sweetness and spice balance of the easy pumpkin cake recipe.

Q: Can I use this recipe to make cupcakes or a bundt cake? A: Yes, you can use the batter for cupcakes or a bundt cake, but the swirl filling will be messier. For a bundt cake, pour half the batter, layer the filling, and top with the rest of the batter, then bake for 50–60 minutes. For cupcakes, layer the batter, drop a small spoonful of filling, and top with more batter, baking for about 20 minutes.

Q: Why did my cinnamon swirl sink to the bottom of the cake? A: The swirl mixture is designed to be heavy. If you didn’t leave enough of the cake batter on the bottom (Step 2) or if your batter was too thin (possibly due to too much oil or milk), the filling will sink. Ensure the bottom layer is thick enough to support the swirl.

Q: What is the best way to keep the pumpkin cake moist? A: The pumpkin puree naturally ensures high moisture. To maximize moisture, do not overbake the cake (pull it out when the toothpick test shows moist crumbs) and always store the cake in an airtight container once cooled.
