Step‑by‑Step Instructions for Pumpkin Bars with Brown Sugar Frosting

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, take an 8×8-inch baking pan and line it with parchment paper or aluminum foil, ensuring there’s some overhang to easily lift the baked bars out later. This preparation sets the stage for baking those delicious Pumpkin Bars with Brown Sugar Frosting.

Step 2: Melt the Butter
In a microwave-safe bowl, melt ½ cup of unsalted butter until it’s just warm, not bubbling. This process usually takes about 30–45 seconds. You’re looking for a smooth, melted texture that brings out a rich flavor in your Pumpkin Bars, perfect for mixing in with the other ingredients.

Step 3: Combine Wet Ingredients
Once the butter has melted, whisk in 1 cup of brown sugar, 1 egg, and 1 teaspoon of vanilla extract along with 1 cup of pumpkin puree until the mixture is well combined and smooth. This step should take about 2 minutes. The vibrant orange pumpkin adds moisture and flavor, creating a delightful base for your bars.

Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of ground cinnamon, ½ teaspoon of ground ginger, ¼ teaspoon of ground nutmeg, 1 teaspoon of baking soda, and ½ teaspoon of fine sea salt. This dry mixture should be combined until evenly distributed, as this will ensure the flavor spreads evenly throughout your Pumpkin Bars.

Step 5: Combine Wet and Dry Ingredients
Gently fold the dry ingredients into the wet mixture with a spatula until just incorporated, taking care not to overmix. This should take about 1-2 minutes. You want a cohesive batter that keeps some of that good moisture for your Pumpkin Bars with Brown Sugar Frosting without losing its tender texture.

Step 6: Pour and Smooth the Batter
Once the batter is mixed, pour it into your prepared baking pan, using a spatula to spread it out evenly. Aim for a smooth top surface to ensure even baking. If you spot any lumps, lightly break them up. This step usually takes around 2-3 minutes and sets you up for the perfect bake.

Step 7: Bake the Bars
Place the pan into the preheated oven and bake for 25 minutes or until a toothpick inserted into the center comes out clean. This is the moment to watch closely; the edges should be lightly golden while the center remains soft yet set, giving you that ideal pumpkin bar texture.

Step 8: Cool the Bars
After baking, let the bars cool in the pan for about 10 minutes before transferring them to a wire rack. This allows them to firm up perfectly. Once they’re cool to the touch, you can proceed to let them sit until fully cooled, which ensures the frosting won’t melt when applied.

Step 9: Prepare the Frosting
In a mixing bowl, beat together ½ cup of softened unsalted butter, 1 cup of brown sugar, ½ teaspoon of ground cinnamon, and a pinch of salt until creamy and well-blended. This should take about 2-3 minutes. Gradually add 2 cups of powdered sugar and a few tablespoons of milk to achieve your desired spreadability.

Step 10: Frost and Serve
Once your Pumpkin Bars are completely cooled, generously spread the brown sugar frosting over the top using a spatula. Aim for an even layer that showcases the creamy texture of the frosting. Finally, cut the bars into squares and get ready to share this scrumptious fall treat with friends and family!
