How to Make Pumpkin Bars with Brown Sugar Frosting
Step 1: Prepare Your Baking Dish
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish or line it with parchment paper for easy removal later. This step ensures that your delicious bars won’t stick when it’s time to serve!
Step 2: Mix the Pumpkin Bar Batter
In a mixing bowl, cream together the unsalted butter and light brown sugar until smooth. This process helps incorporate air into your batter, giving it that lovely soft texture. Add in the egg and vanilla extract next; mix well until combined. Fold in the pumpkin puree gently until everything is incorporated.
Step 3: Combine Dry Ingredients
In another bowl, whisk together all-purpose flour, cinnamon, ginger, nutmeg, baking soda, and salt. Mixing dry ingredients separately prevents clumping and ensures even distribution throughout the batter.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry mixture into your wet mixture while stirring gently. Be careful not to overmix; we want those pumpkin bars soft and tender! Once combined, pour this luscious batter into your prepared baking dish.
Step 5: Bake Time!
Bake your pumpkin bars in the preheated oven for about 25 minutes or until a toothpick inserted comes out clean. The smell wafting from your kitchen will be divine—resist the urge to dive in right away!
Step 6: Make That Frosting
While your bars are cooling down, prepare the brown sugar frosting. In a mixing bowl, cream together unsalted butter and light brown sugar until fluffy. Add ground cinnamon and salt before gradually incorporating powdered sugar. Finally, mix in vanilla extract and milk until you achieve that perfect spreadable consistency.
Step 7: Frost & Enjoy!
Once your pumpkin bars have cooled completely in their pan, generously spread on that delightful frosting. Cut into squares or rectangles as desired—and there you have it! Delicious Pumpkin Bars with Brown Sugar Frosting ready to enjoy!
Pro Tips for Making Pumpkin Bars with Brown Sugar Frosting
Making these Pumpkin Bars with Brown Sugar Frosting can be a breeze if you keep a few helpful tips in mind!
- Use room temperature ingredients: This helps the butter and egg mix together smoothly, creating a light and fluffy batter that bakes evenly.
- Don’t overmix the batter: Stir just until the flour is incorporated. Overmixing can lead to dense bars instead of the soft, tender treat we want.
- Sift your powdered sugar: Sifting removes lumps and ensures a smooth frosting that spreads beautifully over your pumpkin bars.
- Adjust the milk in frosting as needed: Start with 1 tablespoon of milk; add more gradually to achieve your desired consistency. A thicker frosting holds its shape, while a thinner one is easier to spread.
- Cool completely before frosting: Letting your bars cool completely prevents the frosting from melting into the warm cake, keeping it beautifully thick and delicious.
