Step‑by‑Step Instructions for Sour Cream Pumpkin Bars
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grease a 9×13-inch baking pan with butter or cooking spray to ensure the bars release easily. Set the prepared pan aside, ready to hold your delicious Sour Cream Pumpkin Bars once the batter is ready.
Step 2: Mix Dry Ingredients
In a large, dry mixing bowl, whisk together the all-purpose flour, sugar, baking powder, baking soda, salt, cinnamon, and nutmeg. This step is crucial for evenly distributing the leavening agents and spices, ensuring your bars rise beautifully and are infused with that warm, autumn flavor.
Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the pumpkin puree, sour cream, eggs, melted butter, and vanilla extract until the mixture is smooth and well-blended. This amalgamation brings moisture and richness to your Sour Cream Pumpkin Bars, which is key to achieving the perfect texture.
Step 4: Merge Wet and Dry Ingredients
Carefully fold the wet ingredients into the dry mixture using a spatula or wooden spoon. Be gentle to avoid overmixing; a few lumps are perfectly fine! This is where the magic happens as the ingredients come together to form a luscious batter bursting with pumpkin goodness.
Step 5: Bake the Bars
Pour the batter into the prepared 9×13-inch pan, spreading it evenly with a spatula. Place the pan in the preheated oven and bake for 25-28 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs to indicate your Sour Cream Pumpkin Bars are ready.
Step 6: Cool the Bars
Once baked, remove the pan from the oven and set it on a wire rack to cool completely in the pan. This step is essential to allow the bars to set properly. Patience is key, as they need to reach room temperature for ideal frosting application.
Step 7: Prepare the Frosting
In a light-colored saucepan, melt unsalted butter over medium heat. Swirl occasionally until it turns golden brown and develops a nutty aroma, which should take about 5-7 minutes. Once ready, set it aside to cool slightly while you prepare the powdered sugar mixture.
Step 8: Frost the Bars
In a mixing bowl, whisk together the browned butter, powdered sugar, milk, and vanilla extract until smooth and creamy. Once the Sour Cream Pumpkin Bars have cooled completely, generously spread the frosting over the top, ensuring an even layer for a delightful finishing touch.
Step 9: Serve and Enjoy
Once frosted, cut the bars into squares and serve them at room temperature. Each bite of your Sour Cream Pumpkin Bars, enriched by the browned butter frosting, is sure to be a hit. Enjoy the taste of autumn with every delicious piece!

How to Store and Freeze Sour Cream Pumpkin Bars
Room Temperature: Keep bars in an airtight container at room temperature for up to 2 days; layer with parchment paper to prevent sticking and maintain freshness.
Fridge: Store in the refrigerator for up to 5 days. Use an airtight container to keep the Sour Cream Pumpkin Bars moist and protect them from absorbing other odors.
Freezer: Wrap cooled bars tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag. They can be frozen for up to 3 months; thaw overnight in the fridge when ready to enjoy.
Reheating: For a cozy treat, warm bars slightly in the microwave or allow them to come to room temperature before serving for that lovely fall flavor experience.
Make Ahead Options
These Sour Cream Pumpkin Bars are perfect for busy home cooks who want to save time without sacrificing flavor! You can prepare the batter up to 24 hours in advance; simply mix the wet and dry ingredients separately and store them in the refrigerator. You can also bake the bars ahead and keep them covered at room temperature for up to 3 days or refrigerate them for up to 5 days. For the best results, frost the bars just before serving to maintain that soft and creamy texture of the browned butter frosting. This way, you can enjoy the delightful taste of your homemade dessert with minimal effort on the day you’re ready to serve!

Sour Cream Pumpkin Bars with Heavenly Browned Butter Frosting Recipe FAQs
What type of pumpkin should I use?
Absolutely! You can use either canned pure pumpkin or freshly roasted pumpkin for these bars. Canned pumpkin is super convenient and ensures a consistent flavor, while roasting pumpkin can add a unique depth of taste. Whichever you choose, just make sure it’s pure pumpkin and not pumpkin pie filling.
How should I store my Sour Cream Pumpkin Bars?
For optimal freshness, store the bars in an airtight container at room temperature for up to 2 days. If you need to keep them longer, place them in the fridge where they can last up to 5 days. Make sure to layer parchment paper between the bars to keep them from sticking together.
Can I freeze Sour Cream Pumpkin Bars?
Absolutely! To freeze your Sour Cream Pumpkin Bars, first, allow them to cool completely. Then, wrap them tightly in plastic wrap or aluminum foil, ensuring there is no air inside, and place them in a freezer-safe bag. They’ll stay fresh for up to 3 months. When you’re ready to enjoy them, simply thaw them overnight in the fridge.
What if my batter is too thick?
If your batter seems too thick after mixing, don’t worry! This can happen if too much flour is added. You can gently stir in a tablespoon or two of milk until you reach the desired consistency. Always remember, the batter should be thick but pourable, so it spreads easily in the pan.
Are these bars suitable for people with allergies?
Good question! For a dairy-free option, substitute the sour cream with coconut cream or use Greek yogurt. If nut allergies are a concern, skip any nut additions and stick with the basic recipe for a safe and delightful treat. Always double-check the labels of your ingredients to ensure they meet your dietary needs.
How long does it take for the bars to cool before frosting?
It’s essential to let your Sour Cream Pumpkin Bars cool completely in the pan for at least 1 hour before frosting. This allows them to set and ensures your frosting doesn’t melt away into a gooey mess. The patience will pay off with beautifully frosted bars!
