Step‑by‑Step Instructions for Sour Cream Pumpkin Bars
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C), creating the perfect baking environment for your Sour Cream Pumpkin Bars. While the oven is warming up, take a 9×13 inch baking pan and generously grease it with butter to ensure easy removal of the bars later.
Step 2: Mix the Dry Ingredients
In a medium-sized mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, salt, ground cinnamon, and nutmeg until they are well combined. This step will ensure even distribution of the leavening agents and spices, bringing warmth and flavor to your Sour Cream Pumpkin Bars.
Step 3: Combine the Wet Ingredients
In another large mixing bowl, mix together the pumpkin puree, sour cream, eggs, melted butter, and vanilla extract. Blend these ingredients until the mixture is smooth and creamy, ensuring the sour cream is well incorporated to add that delightful moisture to your bars.
Step 4: Combine Mixtures
Carefully pour the wet ingredients into the bowl with the dry ingredients. Using a spatula, gently fold the two mixtures together until just combined—be cautious not to overmix, as this will help maintain the tender texture of your Sour Cream Pumpkin Bars.
Step 5: Bake the Bars
Spread the batter evenly into the prepared pan, smoothing the top with a spatula. Place the pan in your preheated oven and bake for 25-28 minutes. Start checking for doneness around the 20-minute mark; the bars should feel lightly springy to the touch and a toothpick inserted in the center should come out with moist crumbs.
Step 6: Cool the Bars
Once baked, remove the pan from the oven and allow the bars to cool completely in the pan on a wire rack. Patience is key here, as cooling prevents the frosting from melting when you spread it on top of your delicious Sour Cream Pumpkin Bars.
Step 7: Make the Browned Butter Frosting
In a medium saucepan over medium heat, melt the butter and continue to cook it until it turns a rich golden brown color, being careful not to let it burn. Remove it from the heat, allow it to cool briefly, then whisk in powdered sugar, milk, and vanilla until smooth and pourable for your luscious frosting.
Step 8: Frost the Bars
Once the Sour Cream Pumpkin Bars have cooled completely, take the frosting and pour it over the top. Use a spatula to spread it evenly, ensuring every bite is decadent and flavorful. Now your bars are ready to be sliced and shared!

Expert Tips for Sour Cream Pumpkin Bars
