Sourdough Pumpkin Bars Ingredients
For the Bars
• Pumpkin Purée – Adds moisture and natural sweetness; substitute with homemade pumpkin puree for a fresher taste.
• Granulated Sugar – Sweetens the bars; replace with coconut sugar for a lower glycemic option.
• Brown Sugar – Adds depth and a bit of moisture; can be substituted with light or dark brown sugar depending on preference.
• Avocado Oil – Provides richness and moisture; any neutral oil like canola or melted coconut oil works too.
• Eggs – Binds the ingredients together; for a vegan substitute, use flax eggs (1 tbsp ground flaxseed mixed with 2.5 tbsp water per egg).
• Vanilla Extract – Enhances flavor; use pure vanilla extract for best results.
• Sourdough Discard – Gives a unique flavor essential for Sourdough Pumpkin Bars; can be adjusted based on how much you have.
• All-Purpose Flour – Provides structure; substitute with a gluten-free flour blend for a gluten-free option.
• Ground Cinnamon & Pumpkin Pie Spice – Adds warmth and holiday flavors; freshly ground spices can elevate the taste.
• Baking Powder & Baking Soda – Helps the bars rise; ensure they are fresh for best results.
• Kosher Salt – Balances sweetness; feel free to swap with sea salt as an alternative.
For the Cream Cheese Frosting
• Cream Cheese – Creates a rich frosting; for a dairy-free version, use vegan cream cheese.
• Unsalted Butter – Adds creaminess; substitute with vegan butter or margarine if needed.
• Powdered Sugar – Sweetens and thickens the frosting; adjust amount to taste and desired consistency.
• Milk or Cream (optional) – Thins the frosting if too thick; non-dairy alternatives work wonderfully here.
Step‑by‑Step Instructions for Sourdough Pumpkin Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven is warming up, prepare a 10×15-inch jelly roll pan by greasing it or laying down parchment paper to prevent sticking. This initial step ensures that your Sourdough Pumpkin Bars bake evenly to perfection.
Step 2: Mix Wet Ingredients
In a large mixing bowl, whisk together the pumpkin purée, granulated sugar, brown sugar, avocado oil, eggs, vanilla extract, and sourdough discard. Continue mixing until well combined and the mixture looks smooth and creamy. This forms the flavorful base of your Sourdough Pumpkin Bars, and the vibrant orange hue will bring autumn vibes to your kitchen.
Step 3: Combine Dry Ingredients
In a separate bowl, mix together the all-purpose flour, ground cinnamon, pumpkin pie spice, baking powder, baking soda, and kosher salt. Whisk these dry ingredients thoroughly until well blended. This step is crucial for ensuring that your Sourdough Pumpkin Bars rise beautifully with a warm, spiced flavor profile.
Step 4: Combine Wet and Dry Mixtures
Gently fold the dry ingredients into the wet mixture, being cautious not to over-mix. Stir until just combined; a few flour streaks are perfectly fine. This careful folding ensures the bars remain soft and tender, creating that melt-in-your-mouth experience you crave from Sourdough Pumpkin Bars.
Step 5: Pour and Bake
Pour the batter into your prepared pan, spreading it evenly with a spatula. Place it in the preheated oven and bake for 20–25 minutes. You’ll know they’re done when a toothpick inserted in the center comes out clean. The bars should be set and slightly spring back when touched.
Step 6: Cool Completely
Once baked, remove the pan from the oven and let the Sourdough Pumpkin Bars cool in the pan for about 10 minutes. Afterward, carefully transfer the bars to a wire rack to cool completely. Allowing them to cool fully is essential before frosting, as it helps maintain the frosting’s pristine texture.
Step 7: Prepare the Frosting
While the bars cool, prepare the cream cheese frosting. In a mixing bowl, beat the cream cheese and unsalted butter together until fluffy. Gradually add the powdered sugar and mix in the vanilla extract and a pinch of salt. Adjust the consistency with milk if needed; it should be smooth and spreadable.
Step 8: Frost the Bars
Once your Sourdough Pumpkin Bars have fully cooled, spread the cream cheese frosting evenly over the top. This luscious layer enhances the flavors, making every bite a delightful experience. For a neater finish, consider chilling the frosted bars in the fridge for a little while.
Step 9: Slice and Serve
After chilling, it’s time to cut the Sourdough Pumpkin Bars into squares or rectangles to serve. You can present them on a beautiful platter for gatherings or enjoy them casually at home. Each bite promises a delightful blend of flavors and autumn warmth, perfect for any occasion.

Very often, this could result from over-mixing or using too much flour. To achieve that lovely light texture, gently fold in the dry ingredients until just combined, leaving a few flour streaks. Be cautious with measuring flour; spoon it into the measuring cup rather than scooping straight from the bag to avoid packing.
