Step‑by‑Step Instructions for Sour Cream Pumpkin Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking pan generously with butter or cooking spray to ensure easy removal later. It’s essential that your pan is well-prepared so your Sour Cream Pumpkin Bars release perfectly, leaving no crumb behind!
Step 2: Mix the Dry Ingredients
In a medium mixing bowl, whisk together the flour, sugar, baking powder, baking soda, salt, cinnamon, and nutmeg. This ensures even distribution of the dry ingredients, which is crucial for the perfect rise. Look for a uniform mixture, free of lumps, before moving on to the wet ingredients.
Step 3: Combine the Wet Ingredients
In a separate large mixing bowl, blend the pumpkin, sour cream, eggs, melted butter, and vanilla extract until smooth. Use a hand whisk or electric mixer on low speed for about 2-3 minutes. This step creates a creamy base, full of moisture and pumpkin flavor, ready to be combined with the dry ingredients.
Step 4: Combine Wet and Dry Mixtures
Gently fold the wet mixture into the dry ingredients using a spatula. Be careful to combine them until just mixed; it’s fine if there are a few lumps. Overmixing can lead to denser bars, and you want to maintain the light and tender texture that makes the Sour Cream Pumpkin Bars irresistible.
Step 5: Bake the Bars
Pour the batter into your prepared baking pan and spread it evenly with a spatula, smoothing the top. Place in the preheated oven and bake for 25-28 minutes. They are done when a toothpick inserted in the center comes out with a few moist crumbs—this ensures that your bars remain deliciously moist.
Step 6: Cool the Bars
Once baked, remove the pan from the oven and let it cool completely in the pan on a wire rack. This cooling period allows the flavors to settle while also making frosting easier. Be patient and resist the urge to frost them while still warm to avoid melting the frosting!
Step 7: Prepare the Browned Butter Frosting
In a saucepan over medium heat, melt the butter until it turns golden brown, stirring constantly (about 4-5 minutes). The nutty aroma signals that it’s ready. Remove from heat and stir in powdered sugar, milk, and vanilla until smooth. Adjust the consistency with more milk or sugar as needed for a perfect frosting.
Step 8: Frost and Serve
Once the Sour Cream Pumpkin Bars have cooled, spread the luscious browned butter frosting evenly on top. Allow the frosting to set for a few minutes before slicing into squares or rectangles. Enjoy sharing these delightful bars with family and friends—autumn sweetness is just a bite away!
