- 🎃 15 oz. can pumpkin puree (make sure it’s puree, not pie filling!)
- 🌾 2 cups all-purpose flour
- ✨ 2 teaspoons baking powder

- 🧂 1/2 teaspoon salt
- 🍂 2 teaspoons ground cinnamon
- 🫚 1/2 teaspoon ground ginger

For the Cream Cheese Frosting:

- 🧀 8 oz. package cream cheese, softened
- 🌬️ 4 cups powdered sugar
- 🍦 2 teaspoons vanilla extract
- 🥛 1/3 cup milk
Detailed Step-by-Step Directions
Let’s get baking! Follow these simple steps to bring your irresistible Pumpkin Spice Cake Bars to life:
- Begin by preheating your oven to a cozy 350°F (175°C). Lightly grease and flour a 12″x18″ half sheet pan, ensuring a non-stick surface for your delicious bars. This step is key for easy removal!
- In a large mixing bowl, gently combine the eggs, vegetable oil, granulated sugar, and pumpkin puree. Stir until these wholesome wet ingredients are wonderfully blended into a smooth, orange-hued mixture.
- Next, it’s time for the spice magic! Gradually add all the dry ingredients – flour, baking powder, baking soda, salt, cinnamon, ginger, cloves, and nutmeg – to the pumpkin mixture. Mix carefully until everything is just combined into a smooth, uniform batter. Remember, avoid overmixing to keep your cake bars incredibly tender!
- Pour the beautifully spiced batter evenly into your prepared sheet pan, spreading it gently with a spatula to reach all corners.
- Bake for 25 to 30 minutes, or until a toothpick inserted into the center of the cake comes out perfectly clean, indicating it’s done. Remove from the oven and let the cake cool completely on a wire rack while you prepare the creamy, dreamy frosting. Patience is a virtue here; a warm cake will melt your frosting!
- While the cake cools, prepare your decadent frosting. In another spacious bowl, beat the softened cream cheese and butter together until they are wonderfully smooth, light, and airy.
- Add the powdered sugar, vanilla extract, and milk to the cream cheese mixture. Continue beating until the frosting is light, fluffy, and perfectly smooth – a cloud of sweet perfection!
- Once your pumpkin cake is thoroughly cooled (and we mean *completely* cooled!), spread the irresistible cream cheese frosting evenly over the top. Slice into generous bars and get ready to enjoy this delightful, homemade treat!
Ways to Present and Serve Your Pumpkin Spice Cake Bars
These Pumpkin Spice Cake Bars are already a showstopper, but with a few creative touches, you can elevate them even further! Here are some delightful ways to present and serve them:
- Classic & Simple: A light dusting of powdered sugar or a sprinkle of extra cinnamon on top of the frosting adds a lovely touch without overpowering the flavors.
- Nutty Crunch: Sprinkle chopped toasted pecans, walnuts, or candied almonds over the frosting for added texture and a complementary nutty flavor.
- Caramel Drizzle Dream: A generous drizzle of warm caramel sauce over the frosted bars before serving adds an extra layer of sweetness and sophistication.
- Chocolate Lover’s Twist: Mini chocolate chips or a delicate drizzle of melted dark chocolate can be a surprising and delicious addition to the pumpkin and spice notes.
- Festive Flair: For a holiday gathering, add some cute candy corn or small edible autumn leaves on top of each bar.
Serve these bars with a steaming mug of coffee, a warm cup of apple cider, or a tall glass of milk for the ultimate cozy experience. They’re perfect for dessert after dinner, a delightful afternoon treat, or even a special breakfast indulgence. Pack them in lunchboxes for a sweet surprise or bring them to any fall gathering – they’re guaranteed to be a hit!
How to Store Your Pumpkin Spice Cake Bars and How Long They Last
To keep your delicious Pumpkin Spice Cake Bars fresh and flavorful, proper storage is key, especially with that luscious cream cheese frosting!
- Refrigeration is a Must: Because of the cream cheese frosting, these bars should be stored in an airtight container in the refrigerator. This will keep the frosting firm and prevent spoilage.
- How Long Do They Last?: When stored correctly in the refrigerator, your Pumpkin Spice Cake Bars will stay fresh and delicious for up to 3-5 days.
- Bringing to Room Temperature: For the best flavor and texture, take the bars out of the fridge about 15-30 minutes before serving. This allows the cake to soften slightly and the frosting to become perfectly creamy.
- Freezing for Later: Yes, you can freeze them! Place unfrosted or frosted bars (if frosted, freeze solid on a baking sheet first, then wrap individually) in an airtight, freezer-safe container or freezer bag. They will keep well in the freezer for up to 1-2 months. Thaw in the refrigerator overnight before serving.
Just make sure they are completely cooled before frosting and storing to prevent condensation, which can make them soggy.
Pumpkin Spice Cake Bars FAQs
Got questions about these delightful Pumpkin Spice Cake Bars? We’ve got answers!
- Can I use pumpkin pie filling instead of pumpkin puree?
No! It’s very important to use 100% pure pumpkin puree. Pumpkin pie filling contains added sugars and spices, which will significantly alter the flavor and texture of your cake bars. - What if I don’t have all the individual spices?
No problem! You can substitute the cinnamon, ginger, cloves, and nutmeg with 3-4 teaspoons of pumpkin pie spice blend. Adjust to your taste! - Can I make these Pumpkin Spice Cake Bars ahead of time?
Absolutely! These bars are wonderful made a day in advance. In fact, some say the flavors deepen and become even better after a day in the fridge. Store them in an airtight container in the refrigerator. - How do I know when the cake is perfectly baked?
The best way is the toothpick test! Insert a toothpick into the center of the cake. If it comes out clean with no wet batter attached, your cake is done. - My cream cheese frosting is too thin/thick. How do I fix it?
If it’s too thin, add more powdered sugar, a tablespoon at a time, until it reaches your desired consistency. If it’s too thick, add a tiny splash more milk (or cream), a teaspoon at a time, until it’s perfectly spreadable. - Can I halve or double this recipe?
Yes, you can! To halve, use a smaller 9×13 inch pan and adjust baking time accordingly (likely 20-25 minutes). To double, you’ll need two 12×18 inch sheet pans or bake in batches. - Is there a gluten-free option for the flour?
While not tested with this specific recipe, many bakers have success substituting all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum. Results may vary slightly. - What kind of vegetable oil is best for these bars?
Any neutral-flavored vegetable oil like canola, sunflower, or grapeseed oil works perfectly. These oils add moisture without imparting a strong flavor of their own. - Can I skip the frosting?
You technically can, but the cream cheese frosting is a beloved part of what makes these Pumpkin Spice Cake Bars so special! The tanginess of the frosting perfectly complements the sweet and spicy cake. - How many calories are in each bar?
Based on the provided nutrition, each serving (1 bar) contains approximately 463 kcal.
