Step‑by‑Step Instructions for Sour Cream Pumpkin Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grease a 9×13-inch baking pan with butter or non-stick spray. This will ensure your Sour Cream Pumpkin Bars will come out easily after baking, leaving you with clean edges for perfect squares.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, brown sugar, baking powder, baking soda, salt, ground cinnamon, and ground nutmeg. Make sure there are no lumps and that the dry ingredients are evenly combined. This mixture serves as the foundation for your pumpkin bars, providing structure and flavor.
Step 3: Combine Wet Ingredients
In another bowl, combine the pumpkin puree, sour cream, eggs, melted butter, and vanilla extract. Use a whisk or electric mixer on low speed to mix until smooth and creamy. The creamy mixture will bring moisture to your Sour Cream Pumpkin Bars, ensuring a tender texture that’s bursting with flavor.
Step 4: Incorporate Wet into Dry
Gently fold the wet mixture into the dry ingredients using a spatula or wooden spoon. Be careful not to overmix; you want the ingredients just combined for the best texture. Once combined, the batter will appear thick and luscious, ready to bring your pumpkin dessert to life.
Step 5: Bake the Pumpkin Bars
Pour the batter into the greased baking pan, spreading it evenly with a spatula. Place the pan in the preheated oven and bake for 25–28 minutes, or until a toothpick inserted in the center comes out with moist crumbs. Keep an eye on them starting at 20 minutes; perfect bars will have a golden top and a soft texture.
Step 6: Cool the Bars
Once baked, remove the pan from the oven and let it cool in the pan on a wire rack. Allow the Sour Cream Pumpkin Bars to cool completely, which usually takes about 30 minutes. This cooling step is crucial as it helps the bars firm up, making them easier to frost and cut.
Step 7: Prepare Browned Butter Frosting
While the bars cool, prepare the browned butter frosting. In a saucepan over medium heat, melt butter, swirling occasionally, until it turns golden brown and develops a nutty aroma, about 5–7 minutes. Be cautious not to burn it; this step adds a rich depth to your frosting.
Step 8: Frost the Bars
After the browned butter has cooled slightly, transfer it to a mixing bowl and mix in powdered sugar, milk, and vanilla extract. Stir until you reach a creamy, spreadable consistency. Once the bars have cooled completely, generously frost the top, creating a beautiful finish that enhances the flavors of the Sour Cream Pumpkin Bars.
Step 9: Let it Set
Allow the frosted bars to sit at room temperature for at least 10 minutes, letting the frosting set before cutting. This final step helps your delicious bars maintain their shape when sliced, ready for sharing or enjoying yourself.

Tips for the Best Sour Cream Pumpkin Bars
-
Measuring Flour: Use the spoon and level method to avoid dense bars. Too much flour can ruin the texture, making them less moist.
-
Cooling Time: Allow the bars to cool completely in the pan before frosting. This helps maintain the integrity of the Sour Cream Pumpkin Bars and makes for easier cutting.
-
Browning Butter: Keep a close eye on the butter while browning to prevent burning. It should be nutty and golden, which adds a rich flavor to the frosting.
-
Frosting Consistency: If your frosting is too thin, let it sit briefly to thicken. For a thicker consistency, add milk gradually until you achieve your desired texture.
-
Customize with Toppings: Enhance your Sour Cream Pumpkin Bars by adding nuts or chocolate chips to the batter before baking. This adds texture and flavor that everyone will love.
Make Ahead Options
These Sour Cream Pumpkin Bars are a fantastic choice for meal prep! You can prepare the batter up to 24 hours in advance; simply mix the wet and dry ingredients separately, then combine them and refrigerate the batter until you’re ready to bake. The bars themselves can be baked ahead of time and stored in an airtight container for up to 3 days at room temperature, ensuring they remain just as moist and delicious. When ready to indulge, simply frost them right before serving for that fresh taste, and you’ll enjoy pumpkin perfection without the last-minute rush!

Sour Cream Pumpkin Bars with Heavenly Browned Butter Frosting Recipe FAQs
What should I look for when selecting pumpkin puree?
Absolutely! When choosing pumpkin puree, look for a pure pumpkin product without any added spices or sugars. A good puree should be smooth and vibrant orange. If possible, prefer brands that use only 100% pumpkin, as some canned varieties may have mixed ingredients. You can also use homemade pumpkin puree if you’re up for roasting a fresh pumpkin!
How should I store leftover Sour Cream Pumpkin Bars?
For optimal freshness, store your Sour Cream Pumpkin Bars in an airtight container lined with parchment paper to prevent sticking. Keep them at room temperature for up to 2 days or refrigerate for about 5 days. Just make sure they’re completely cooled before storing to maintain their delicious moistness!
Can I freeze Sour Cream Pumpkin Bars for later?
Very much! You can freeze these bars for up to 3 months. To do this, let them cool completely after baking, then slice into squares and layer them in an airtight container or freezer bag with parchment paper in between to keep them from sticking. When you’re ready to enjoy, simply thaw them in the fridge overnight.
What if my bars turn out too dense or dry?
If your Sour Cream Pumpkin Bars are dense, it may be due to too much flour or overmixing the batter. Remember to use the spoon-and-level method for measuring flour to avoid packing it down. If they come out dry, it could be a sign of overbaking, so I recommend checking them a few minutes before the intended baking time. Ideally, they should come out with moist crumbs on the toothpick!
Can I make these bars dairy-free or vegan?
Absolutely! You can easily make these Sour Cream Pumpkin Bars vegan by replacing the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg) and using coconut oil or dairy-free butter in place of regular butter. For the sour cream, opt for coconut cream or any plant-based yogurt to maintain the creamy texture.
How long will the browned butter frosting last?
The browned butter frosting is best fresh, but if you have leftovers, store it in an airtight container in the fridge for up to 1 week. Before using, simply give it a quick stir to return to the right consistency. If it’s too thick, you can add a little milk to achieve your desired spreadability.
