How to Make Pumpkin Bars with Brown Sugar Frosting
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that your bars bake evenly and come out soft and fluffy.
Step 2: Prepare the Batter
In a mixing bowl, cream together the unsalted butter and light brown sugar until it’s light and fluffy. Adding the egg and vanilla extract next will help bind everything together while adding flavor. After that, mix in the pumpkin puree until well combined. In another bowl, whisk together the dry ingredients—flour, spices, baking soda, and salt—then gently fold them into the wet mixture until just combined.
Step 3: Bake Your Bars
Pour your batter into a greased baking pan and spread it evenly. Bake for about 25 minutes or until a toothpick inserted comes out clean. The smell wafting through your kitchen will be heavenly!
Step 4: Make the Frosting
While your bars are cooling down, prepare the brown sugar frosting. Cream together more unsalted butter with brown sugar, then mix in cinnamon and salt. Gradually add powdered sugar along with milk until smooth and spreadable. Adjust with more milk if needed!
Step 5: Frost and Serve
Once your pumpkin bars have cooled completely, generously spread the frosting on top. Cut into squares or rectangles as desired. Now you’re ready to enjoy these delightful treats!
These Pumpkin Bars with Brown Sugar Frosting are sure to become a favorite in your household!
Pro Tips for Making Pumpkin Bars with Brown Sugar Frosting
Making these delicious Pumpkin Bars with Brown Sugar Frosting is a breeze if you follow a few simple tips!
- Use room temperature ingredients – Ensure your butter and egg are at room temperature. This helps them blend together more smoothly, resulting in a lighter texture for the bars.
- Sift your flour and powdered sugar – Sifting removes lumps and ensures an even distribution of dry ingredients, leading to a fluffier bar and a smoother frosting.
- Don’t overmix the batter – Mix just until combined to avoid tough bars. Overmixing can lead to gluten development, making the bars denser than desired.
- Let them cool completely before frosting – Frosting warm bars can cause the frosting to melt and slide off. Allow the bars to cool completely for the best results.
- Store them properly – Keep any leftover bars in an airtight container at room temperature or in the refrigerator for extended freshness. This keeps them soft and delicious for days!
How to Serve Pumpkin Bars with Brown Sugar Frosting
Serving these pumpkin bars can be as creative as you like! Here are some ideas on how to present this delightful treat.
Garnishes
- Chopped nuts – Sprinkle some toasted walnuts or pecans on top of the frosting for added crunch and flavor.
- Whipped coconut cream – A dollop of whipped coconut cream can add a light, airy touch that complements the rich frosting.
- Cinnamon sprinkle – Dust a little ground cinnamon over the top just before serving for an extra hint of spice and visual appeal.
Side Dishes
- Apple cider – The crispness of apple cider pairs wonderfully with pumpkin flavors, offering a refreshing contrast.
- Vanilla ice cream (dairy-free if needed) – A scoop of ice cream adds creaminess that balances out the pumpkin spice perfectly.
- Roasted fall vegetables – Serve alongside roasted veggies like butternut squash or sweet potatoes to create a heartier meal experience.
- Salad with maple dressing – A light salad with maple vinaigrette adds brightness and cuts through the sweetness of the dessert, making it a well-rounded meal.
