What makes this frosting truly special is its incredible tang and richness, achieved without any traditional vegan cream cheese, thanks to a surprising secret ingredient that will leave your guests guessing.
Why These Vegan Pumpkin Cake Bars Are Your New Go-To Dessert
- Unbelievably Fluffy and Moist: Prepare to be amazed by the light, airy texture and profound moisture of these pumpkin cake bars. The magic lies in the carefully balanced combination of pumpkin puree, refined coconut oil, and other simple pantry staples.

- Signature Vegan Cream Cheese Frosting: The crowning glory of these bars is a frosting so rich and tangy, it’s indistinguishable from traditional cream cheese icing. The secret behind its authentic flavor is a touch of apple cider vinegar, which provides that essential zesty note without needing specialty vegan cream cheese products. It’s a game-changer that elevates the entire dessert.
- Ideal for Crowds and Holidays: This recipe yields approximately 20 generously sized cake bars, making it an excellent choice for feeding a large group. You’ll have plenty to share at holiday parties, potlucks, or family gatherings, ensuring everyone gets a taste of this delightful autumn dessert. It’s the perfect make-ahead option for busy festive seasons.
- Simple to Make, Impressive to Serve: Despite their gourmet taste and appearance, these pumpkin cake bars are remarkably easy to prepare. Even novice bakers will find success with this straightforward recipe, making it a fantastic addition to your repertoire for effortless entertaining.
Essential Ingredients and Smart Substitutions
Crafting these delectable vegan pumpkin cake bars requires a thoughtful selection of ingredients, many of which you likely already have on hand. Here’s a detailed look at what you’ll need and how to make clever substitutions:
- Ground Flaxseeds: These are crucial for creating the “flax eggs” that act as a binder in our vegan batter. They help hold everything together, contributing to the cake’s structure and moisture. If flaxseeds aren’t available, an equal amount of ground chia seeds can be used as an alternative.
- Water: Combined with ground flaxseeds to form the flax eggs.
- Canned Pumpkin Puree: The heart of our pumpkin cake! It’s vital to use pure canned pumpkin, not pumpkin pie filling, which contains added sugars and spices. Pure pumpkin ensures an authentic flavor and allows you to control the spice levels. This is the same glorious ingredient used in my Vegan Pumpkin Pie.
- Coconut Oil: For a neutral flavor profile that lets the pumpkin shine, opt for refined coconut oil. If you prefer, equally good alternatives include canola oil, avocado oil, or melted vegan butter. For those looking to reduce fat, you can experiment with replacing half of the oil with applesauce, though this may subtly alter the cake’s texture and overall richness.
- Granulated Sugar: Any white sugar, cane sugar, or coconut sugar will work beautifully to sweeten the cake.
- All-Purpose Flour: This is my go-to for achieving a light and fluffy cake crumb. While I haven’t specifically tested a gluten-free version, a high-quality, cup-for-cup Gluten-Free All-Purpose Flour Mix should yield excellent results.
- Baking Powder & Baking Soda: These leavening agents are essential for giving the cake its signature rise and tender texture. Do not skip or substitute them.
- Cinnamon & Nutmeg: The quintessential pumpkin spices! These warm, aromatic spices infuse the cake with irresistible fall flavors. Feel free to add a pinch of ground ginger or cloves for an even richer spice blend.
- Salt: A small amount of salt enhances all the other flavors, balancing the sweetness and deepening the pumpkin taste.
For the Irresistible Frosting:
- Vegan Butter: This forms the creamy base of our incredible “cream cheese” frosting. Ensure it is softened to room temperature for optimal whipping.
- Powdered Sugar (Confectioners’ Sugar): Absolutely essential for both sweetness and the smooth, sturdy consistency needed for frosting. Without it, your icing will lack the desired texture and sweetness.
- Apple Cider Vinegar: The secret ingredient! This provides the crucial tangy flavor that mimics traditional cream cheese icing. Its mild acidity complements the warm spices of the cake perfectly. Lemon juice can be used as a suitable substitute if needed.
- Vanilla Extract: Pure vanilla extract adds a wonderful depth of flavor to the frosting, enhancing its overall richness.
- Non-Dairy Milk: Use any unsweetened non-dairy milk (almond, soy, oat) to gradually thin the frosting to your desired consistency. Add it sparingly, one tablespoon at a time.
Vegan Pumpkin Cake Bars Recipe
This easy vegan pumpkin cake is extra fluffy and topped with vegan cream cheese icing. It’s baked in a large sheet pan, then cut into bars for a sweet and nicely spiced fall treat you can feed to a crowd.
- Prep Time: 15 mins
- Cook Time: 25 mins
- Cooling Time: 30 mins
- Total Time: 1 hr 10 mins
- Servings: 20 slices
Ingredients
- Pumpkin Cake
- 2 tablespoons ground flaxseeds
- 5 tablespoons water
- 15 ounces canned pumpkin puree
- 1 cup melted refined coconut oil (or canola oil, avocado oil, melted vegan butter)
- 1 1/2 cups granulated sugar
- 2 cups all-purpose flour
- 1 tablespoon baking powder
- 1/2 teaspoon baking soda
- 2 teaspoons cinnamon
- 1/2 teaspoon nutmeg
- 1 teaspoon salt
- Frosting
- 8 tablespoons (1/2 cup) vegan butter, softened
- 3 cups powdered sugar
- 1 teaspoon apple cider vinegar
- 1/2 teaspoon pure vanilla extract
- 1-2 tablespoons non-dairy milk, as needed
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 15 x 10 inch jelly roll pan and set it aside.
- In a small bowl, whisk together the ground flaxseed and water. Let this mixture sit for 5-10 minutes until it thickens into a gelatinous “flax egg.” This is your binding agent.
- In a large mixing bowl, combine the pumpkin puree, melted coconut oil, granulated sugar, and your prepared flax eggs. Whisk these wet ingredients together until they are smooth and well-combined.
- To the wet ingredients, gradually add the all-purpose flour. Then, sprinkle the baking powder, baking soda, cinnamon, nutmeg, and salt evenly over the flour. Using a large spoon or spatula, mix until the dry and wet ingredients are just combined. Be careful not to overmix, as this can lead to a dense cake. A few small lumps are perfectly fine.
- Pour the cake batter into the greased jelly roll pan. Use an offset spatula or the back of a spoon to spread the batter evenly to all edges of the pan, ensuring a uniform layer for even baking.
- Bake for 25-30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Once baked, remove the cake from the oven and allow it to cool completely in the pan on a wire rack before you even think about frosting it. This step is crucial to prevent the frosting from melting.
- Make the Frosting: While the cake cools, prepare your irresistible frosting. In a medium bowl, using a handheld or standing mixer, beat the softened vegan butter for about 2 minutes until it becomes light, creamy, and fluffy.
- Gradually add the powdered sugar to the whipped vegan butter, mixing on low speed until just combined, then increase to medium-high speed. Incorporate the apple cider vinegar and vanilla extract. Continue to beat until the frosting is wonderfully smooth and creamy.
- If the frosting is too thick, add non-dairy milk one tablespoon at a time, beating after each addition, until you achieve your desired spreadable consistency. If you accidentally add too much milk and the frosting becomes too thin, simply add more powdered sugar, a quarter cup at a time, until it thickens again.
- Once the cake has cooled entirely, spread the luxurious vegan cream cheese frosting evenly over the top. Cut the cake into individual bars (approximately 20 pieces), serve, and enjoy the blissful flavors of fall!
Recipe Notes for Success
- For a truly neutral flavor in your cake, always use refined coconut oil. Unrefined coconut oil can impart a subtle coconut taste. As mentioned, canola oil, avocado oil, or melted vegan butter are excellent alternatives.
- While this recipe hasn’t been tested with gluten-free flour, most quality cup-for-cup gluten-free flour blends should work well. Expect a slightly different texture, but the flavor will remain fantastic.
- This recipe is designed to yield a generous batch of 20 bars, perfect for entertaining. If you’re baking for a smaller group, feel free to halve all the ingredients and bake in a standard 9 x 13 inch cake pan. Adjust baking time as needed.
- Ensuring the cake is completely cool before frosting is paramount. A warm cake will cause the frosting to melt and slide off, creating a less-than-perfect presentation. To expedite the cooling process, you can place the cake in the refrigerator for a short period once it has mostly cooled at room temperature.
- Store leftover frosted cake bars in an airtight container at room temperature for 2-3 days, or in the refrigerator for 4-5 days. These bars also freeze exceptionally well, either frosted or unfrosted, making them ideal for meal prep or future cravings. Wrap them tightly in plastic wrap and then foil before freezing.

Creative Variations & Serving Suggestions
While these Vegan Pumpkin Cake Bars are perfect as is, they also lend themselves beautifully to various adaptations and serving ideas. Unleash your creativity in the kitchen!
Pumpkin Cupcakes: A Bite-Sized Treat
If you prefer individual servings, this versatile batter can easily be transformed into delightful pumpkin cupcakes. Simply prepare the batter as directed, then divide it evenly among a lined regular-sized cupcake tin. Bake at 350°F (175°C) for approximately 15 to 20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. Frost them with the same tangy vegan cream cheese icing for a charming, portable dessert.
Layered Pumpkin Cake: An Elegant Option
Yes, you can absolutely turn this recipe into a stunning layered cake! This batch of batter is ample enough for two round 9-inch cake pans. Divide the batter, bake as directed (you may need to adjust baking time slightly), and once cooled, stack and frost for an impressive centerpiece dessert. Consider adding a sprinkle of toasted pecans or candied walnuts between layers for added texture and flavor.
Additional Mix-Ins and Toppings:
- Chocolate Chips: Stir in a cup of vegan chocolate chips (dark, semi-sweet, or white) into the batter before baking for a classic pumpkin-chocolate combination.
- Nuts: Fold in chopped walnuts or pecans for a delightful crunch.
- Dried Fruit: Dried cranberries or chopped dates can add a chewy texture and tart sweetness.
- Ginger Glaze: For a different twist, instead of the cream cheese frosting, consider a simple glaze made with powdered sugar, non-dairy milk, and a touch of ground ginger.
- Candied Pecans/Walnuts: Sprinkle these on top of the frosting for an elegant finish and extra crunch.
Frequently Asked Questions About Vegan Pumpkin Cake Bars
Here are some common questions to help you master these delicious pumpkin cake bars:
Q: What size cake pan is best for this recipe?
A: This recipe is designed for a 15 x 10 inch jelly roll pan, which is a standard large sheet pan. It yields approximately 20 substantial bars. If you want fewer bars, you can halve the recipe and bake it in a 9 x 13 inch cake pan. Remember to adjust baking times accordingly for a smaller pan.
Q: Can I make this cake gluten-free?
A: While I haven’t specifically tested a gluten-free version, many readers have successfully adapted my cake recipes using a high-quality, cup-for-cup gluten-free all-purpose flour mix. The texture might be slightly different, but the flavors should still be fantastic. Always ensure your baking powder is gluten-free if you are strictly avoiding gluten.
Q: How do I store leftover pumpkin cake bars?
A: Frosted pumpkin cake bars can be stored in an airtight container at room temperature for 2 to 3 days. For longer freshness, store them in the refrigerator for 4 to 5 days. Be sure they are well-covered to prevent drying out.
Q: Can these cake bars be frozen?
A: Absolutely! This cake freezes exceptionally well, with or without the frosting. To freeze, wrap individual bars or the entire unfrosted cake tightly in plastic wrap, then an additional layer of aluminum foil. This helps prevent freezer burn. They can be stored in the freezer for up to 2-3 months. Thaw overnight in the refrigerator or at room temperature before serving.
Q: Can I make the cake batter ahead of time?
A: It’s generally best to bake the cake batter shortly after mixing to ensure the leavening agents (baking powder and baking soda) are most effective. However, you can prepare your “flax eggs” and even measure out your dry ingredients the day before to save time.
Q: What’s the best way to ensure my frosting is perfectly smooth?
A: Make sure your vegan butter is truly softened to room temperature, but not melted. Beat it well on its own before adding the powdered sugar. Gradually adding the powdered sugar and then beating on medium-high speed for a few minutes will help achieve a light and airy consistency. If lumps remain, a quick sift of the powdered sugar before use can help.
Q: Can I use different spices?
A: Yes! While cinnamon and nutmeg are classics, feel free to experiment with a pre-made pumpkin pie spice blend, or add a pinch of ground ginger, cloves, or allspice for a more complex flavor profile. Adjust quantities to your personal preference.
