Ingredients
- 1 box yellow cake mix (15.25 oz) – This provides structure and flavor. If you prefer, you can use a spice cake mix for an extra boost of cinnamon and nutmeg.
- 15 oz canned pumpkin (not pumpkin pie filling) – Pumpkin keeps the bars moist and adds a rich flavor. Make sure to use pure canned pumpkin, as pumpkin pie filling contains added sugars and spices that may affect the outcome.
- 1 cup water – Helps create the right batter consistency.
- 3 eggs – Adds moisture and structure to the bars. If you need an egg replacement, try using ¾ cup unsweetened applesauce or 3 tablespoons of ground flaxseed mixed with 9 tablespoons of water.
- 1 teaspoon cinnamon – Enhances the warm, autumnal flavor. You can add other spices like nutmeg or allspice if desired.
- ½ cup chocolate chips – These add a delicious contrast to the pumpkin. You can substitute with white chocolate chips, caramel chips, or even chopped nuts for a different texture.
- 16 oz vanilla frosting – Provides a creamy, sweet topping. If you prefer, you can swap it for a homemade cream cheese frosting or a simple powdered sugar glaze.
Instructions
1. Preheat the Oven and Prepare the Baking Dish
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with nonstick cooking spray or butter. This prevents the bars from sticking and makes cutting them easier after baking.
2. Mix the Batter
In a large mixing bowl, combine the cake mix, water, and eggs. Use a hand mixer or whisk to blend until smooth, ensuring there are no dry pockets of cake mix.
Next, add the canned pumpkin, cinnamon, and chocolate chips. Stir until everything is well incorporated. The batter will be thick, which is normal since pumpkin adds density and moisture.
3. Bake the Pumpkin Bars
Pour the batter into the prepared baking dish and spread it evenly using a spatula. Bake for 28 to 30 minutes, or until a toothpick inserted into the center comes out clean.
Once baked, remove from the oven and allow the bars to cool completely before adding the frosting. If they are too warm, the frosting will melt and become too runny.
4. Prepare the Frosting
Remove the lid and foil seal from the vanilla frosting. Microwave it for 25 to 30 seconds, then stir well. This softens the frosting, making it easier to spread evenly over the bars.
5. Frost and Serve
Pour the warmed frosting over the cooled pumpkin bars, spreading it evenly with a spatula. Let the frosting set before slicing into 24 bars. Serve and enjoy.
Notes
1. How to Tell When the Bars Are Done
- Insert a toothpick into the center; if it comes out clean or with a few moist crumbs, they are ready.
- The edges should be slightly golden, and the center should feel firm but soft when lightly pressed.
2. Common Mistakes and How to Fix Them
- If the bars turn out too dense – This is normal due to the pumpkin, but if they feel too heavy, try whisking the eggs separately before adding them. This incorporates air for a lighter texture.
- If the bars are too dry – Check your oven temperature. Some ovens run hotter than others. Try baking at 325°F (163°C) and checking for doneness at 25 minutes.
- If the chocolate chips sink – Toss them in a little flour before adding to the batter. This prevents them from sinking to the bottom.
3. How to Prep Efficiently
- Gather all ingredients before starting to avoid missing anything.
- Use an electric mixer for quicker blending, but a whisk works just fine.
- Line the baking dish with parchment paper if you want to lift the bars out easily for cutting.
