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 heats up, take an 8×8-inch baking pan and line it with foil or parchment paper, allowing some to hang over the edges for easy removal later. This little preparation ensures your Pumpkin Bars with Brown Sugar Frosting will come out effortlessly and remain intact.
Step 2: Melt the Butter
In a medium-sized bowl, melt ½ cup of unsalted butter in the microwave or on the stovetop until it’s completely liquid. Allow it to cool for a few minutes until it’s not too hot to touch, preventing any cooked eggs later in your batter. The melted butter will add the necessary richness to your pumpkin mixture.
Step 3: Combine Wet Ingredients
Whisk in 1 cup of light brown sugar, 1 egg, 1 teaspoon of vanilla extract, and 1 cup of pumpkin puree into the melted butter until everything is well combined and smooth. It should become a rich and inviting mixture, filled with sounds and scents of fall that promise deliciousness in your Pumpkin Bars with Brown Sugar Frosting.
Step 4: Mix the Dry Ingredients
In a large bowl, mix together 1 cup of all-purpose flour, 1 teaspoon each of ground cinnamon, ground ginger, and ground nutmeg, along with 1 teaspoon of baking soda and ½ teaspoon of fine sea salt. Stir gently until the spices and dry ingredients are evenly distributed. This mixture will bring that delightful autumn flavor to your bars.
Step 5: Combine Wet and Dry Mixtures
Gently fold the dry ingredients into the wet mixture from Step 3 until just blended. Avoid overmixing, as this ensures your Pumpkin Bars remain soft and cakey, rather than dense. You’ll know it’s ready when there are no visible streaks of flour left in the batter, and it exudes that inviting aroma of spices.
Step 6: Bake the Pumpkin Bars
Pour the batter into the prepared baking pan, smoothing it out with a spatula to ensure even baking. Place it in your preheated oven and bake for 25 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on the baking process to catch that moment when they’re perfectly set but not overcooked.
Step 7: Prepare the Brown Sugar Frosting
While the bars are baking, prepare your brown sugar frosting. In a bowl, beat together ½ cup of softened unsalted butter and 1 cup of light brown sugar until creamy. Add 2 cups of powdered sugar, 2 tablespoons of milk, ½ teaspoon of vanilla extract, and a pinch of salt, mixing until smooth and perfectly spreadable.
Step 8: Frost the Bars
Once your Pumpkin Bars have completely cooled in the pan, use the edges of the parchment paper to lift them out gently. Place them on a cutting board and frost generously with the prepared brown sugar frosting, creating a delightful layer of sweetness. Cut into bars and marvel at how the creamy frosting complements the rich pumpkin flavor!

Expert Tips for Pumpkin Bars with Brown Sugar Frosting
-
Fresh Spices Matter: Always use fresh spices for the best flavor in your Pumpkin Bars with Brown Sugar Frosting. Expired spices can dull the taste!
-
Correct Pan Choice: Use a light-colored metal pan to ensure even baking; dark pans can overbrown the edges, leading to dry bars.
-
Mix Gently: Avoid overmixing when combining wet and dry ingredients. This keeps your bars soft and slightly cakey instead of dense.
-
Cool Before Frosting: Allow the bars to cool completely before frosting. This prevents the frosting from melting and ensures a beautiful finish.
-
Adjust Frosting Consistency: If your frosting seems too runny, add extra powdered sugar gradually until you reach the desired thickness for spreading.

Reheating: If you prefer your pumpkin bars warm, reheat individual pieces in the microwave for about 10-15 seconds. This brings back that cozy, just-baked feel!

Pumpkin Bars with Brown Sugar Frosting Recipe FAQs
How do I select the best pumpkin puree?
Absolutely! When choosing pumpkin puree, look for deep orange color and a thick consistency. Avoid any pumpkin with watery texture or excessive dark spots on the can, as these can indicate spoilage. If you’re using fresh pumpkin, opt for a sugar pumpkin, as they are sweeter and less fibrous than larger varieties.
Can I store leftover pumpkin bars and for how long?
Very! Store your Pumpkin Bars with Brown Sugar Frosting in an airtight container at room temperature for up to 1 day. If you need more time, refrigerate them for up to 5 days. Just be sure to keep them covered to maintain freshness and frosting texture.
What’s the best way to freeze pumpkin bars?
Certainly! For long-term storage, freeze the unfrosted pumpkin bars for up to 3 months. Wrap each bar individually in plastic wrap, then in aluminum foil to prevent freezer burn. To thaw, simply place them in the refrigerator overnight and frost them just before serving for optimal taste.
What if my pumpkin bars turn out too dry?
Absolutely! If your bars end up dry, ensure that the baking time is correct; an overbaking scenario can cause dryness. Checking doneness with a toothpick should help: it should come out with a few moist crumbs, not completely clean. A addition of a bit of extra pumpkin puree can also help moistness if you find yourself with overbaked bars.
Are these pumpkin bars suitable for gluten-free diets?
Yes! You can substitute all-purpose flour with a gluten-free flour blend to make these Pumpkin Bars with Brown Sugar Frosting gluten-free. Ensure that the alternative flour blend is intended for baking for the best results. Additionally, always double-check your baking powder and other ingredients for gluten cross-contamination.
How can I make these pumpkin bars dairy-free?
Of course! Substitute the unsalted butter with coconut oil or a dairy-free margarine, and use a plant-based milk for the frosting. Replace the egg with a flax egg (1 tablespoon flaxseed meal mixed with 2.5 tablespoons water) for a vegan option. This way, you can enjoy these delicious treats without dairy!
