For the Pumpkin Bars
- 1 stick (113 grams) unsalted butter
- 2/3 cup (133 grams) packed light brown sugar
- 1 large egg (at cool room temperature)
- 1 teaspoon vanilla extract
- 1 cup (212 grams) pumpkin puree
- 1 1/2 cups (190 grams) all-purpose flour
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground ginger
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon baking soda
- 1/4 teaspoon fine sea salt
For the Brown Sugar Frosting
- 1 stick (113 grams) unsalted butter (at cool room temperature)
- 1/4 cup (50 grams) packed light brown sugar
- 1/2 teaspoon ground cinnamon
- 1/8 teaspoon fine sea salt
- 1 1/2 cups (188 grams) powdered sugar (sifted)
- 1/2 teaspoon vanilla extract
- 1 tablespoon milk (plus more if needed)
- Preheat the oven: Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with foil or parchment paper, leaving an overhang for easy removal later.
- Prepare the wet ingredients: In a medium microwave-safe bowl, melt the butter in the microwave. Let it cool to about 80°F (just warm). Then whisk the cooled butter with the brown sugar, egg, vanilla extract, and pumpkin puree until combined.
- Combine dry ingredients: In a large bowl, whisk together the all-purpose flour, ground cinnamon, ground ginger, ground nutmeg, baking soda, and fine sea salt evenly.
- Mix the batter: Pour the wet butter mixture into the dry flour mixture and stir just until combined. The batter will be thick. Spread it evenly into the prepared baking pan using a spatula.
- Bake the bars: Bake for 25 minutes or until a cake tester inserted in the center comes out clean. Be careful not to overbake to maintain moistness. Remove from the oven and set the pan on a wire rack to cool completely.
- Prepare the frosting: Using an electric mixer in a large bowl, beat the butter and brown sugar on medium-high speed until light, fluffy, and smooth. Scrape down the bowl as needed. Add the cinnamon and salt, then gradually add the sifted powdered sugar on low speed until incorporated.
- Finish the frosting: Add vanilla extract and milk, then increase the mixer speed to medium-high and beat for 2-3 minutes until the frosting is very light and fluffy. If too runny, add more powdered sugar; if too thick, add a little more milk.
- Frost the bars: Spread the brown sugar frosting evenly over the cooled pumpkin bars.
- Serve and store: Cut into squares and serve. Store leftovers in an airtight container at room temperature for up to 1 day or refrigerate for up to 5 days.
Notes
- Make sure the butter used in the frosting is at cool room temperature to achieve a smooth, creamy texture.
- Do not overbake the bars to keep them moist and tender.
- For a more intense spice flavor, you can adjust the cinnamon, ginger, and nutmeg to taste.
- If the frosting is too runny, adding more powdered sugar will thicken it up for easier spreading.
- Using parchment paper with an overhang helps lift the bars from the pan easily.
