These are sheet-pan pumpkin bars spiced with cinnamon, ginger, nutmeg, and cloves, finished with a tangy cream cheese frosting. The whole thing comes together in about an hour and slices cleanly into 12 bars. The real reason to make them: they hold up beautifully for days, which makes them one of the most practical bakes you can have in your fall rotation.
What makes this version work
Two things matter most here. First, using melted butter rather than creamed butter keeps the crumb tender and moist without any risk of over-mixing the fat. It also means no stand mixer needed. Second, folding the wet ingredients into the dry just until combined — and stopping there — is what separates a soft bar from a tough one. Pumpkin puree adds a lot of moisture, so the batter can look slightly under-mixed and still bake through perfectly. Trust the toothpick test at 25 minutes rather than going by color alone, because the pumpkin keeps the surface looking dark even before the bars are fully set.
About the ingredients
- Pumpkin puree: Use plain canned pumpkin, not pumpkin pie filling. Pie filling already contains sugar and spices, and it will throw off the balance of this recipe entirely.
- Brown sugar: Pack it firmly into the measuring cup. Loosely spooned brown sugar can leave you short by a meaningful amount, and these bars need that moisture and depth.
- Eggs at room temperature: Cold eggs can cause the melted butter to seize slightly and create a lumpy batter. Set them out 20 minutes before you start.
- Coconut oil swap: If substituting coconut oil for butter, use refined coconut oil. Unrefined adds a noticeable coconut flavor that competes with the spices.
Keeping it fresh
Unfrosted bars keep well at room temperature, covered tightly, for up to two days — ideal if you’re baking the night before an event. Once frosted with cream cheese frosting, they need to be refrigerated and will stay fresh for up to five days. For longer storage, freeze the unfrosted bars: wrap the whole slab in plastic wrap, then foil, and freeze for up to three months. Thaw overnight in the refrigerator still wrapped, then frost and cut the next day. Cutting after thawing gives you cleaner edges than cutting before freezing. Skip dusting with powdered sugar as a garnish if you’re storing these — it dissolves within an hour and just makes a mess.
Mistakes to avoid
- Skipping the parchment overhang: Without it, you’ll be prying bars out of the pan and breaking them. Let the parchment hang over at least two sides so you can lift the whole slab out cleanly before cutting.
- Cutting while warm: These bars look set but are still soft inside when they first come out. Cutting too soon gives you crumbled edges and bars that fall apart. Cool completely — at least 90 minutes at room temperature.
- Using a pan that’s too dark: A dark nonstick pan absorbs more heat and can overbake the bottom before the center is done. A light-colored metal pan gives you more even results. If a dark pan is all you have, check at 22 minutes.
- Measuring flour by scooping: Scooping packs the flour and can add 20–30% more than the recipe intends, making the bars dry and dense. Spoon flour into the measuring cup and level it off.
- Frosting a warm slab: Cream cheese frosting melts and slides off bars that haven’t fully cooled. If you’re in a hurry, transfer the pan to the freezer for 20 minutes rather than skipping the cooling step.
Spiced Pumpkin Bars
Equipment
- Large Mixing Bowl
- Medium mixing bowl
- Whisk
- 9x13 inch baking pan
- Parchment Paper
- Spatula
Ingredients
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- 1 teaspoon ground ginger
- ½ teaspoon ground nutmeg
- ½ teaspoon salt
- 1 cup unsalted butter melted
- 1 cup brown sugar packed
- 1 cup granulated sugar
- 1 cup pumpkin puree canned or homemade
- 4 large eggs room temperature
- 1 teaspoon vanilla extract
Instructions
- Preheat your oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, allowing some to overhang for easy removal.
- In a large mixing bowl, whisk together flour, baking powder, baking soda, cinnamon, ginger, nutmeg, and salt. Set aside.
- In a medium mixing bowl, blend melted butter with brown sugar and granulated sugar until smooth and creamy.
- Add pumpkin puree, eggs, and vanilla extract to the sugar mixture and mix until everything is well combined and smooth.
- Fold the wet ingredients into the dry ingredients gently with a spatula until just combined. Be careful not to over-mix to keep the bars tender.
- Pour the batter evenly into the prepared baking pan and smooth the top with a spatula.
- Bake in the preheated oven for 25 to 30 minutes, or until the edges start to pull away from the pan and a toothpick inserted in the center comes out clean or with slightly moist crumbs.
- Allow the bars to cool completely in the pan on a wire rack before lifting them out with the parchment paper overhang.
- Once cool, cut into 12 bars and serve.
Notes
- For extra flavor, consider adding 1/2 cup of chopped walnuts or pecans to the batter.
- For a dairy-free version, substitute butter with coconut oil.
- For a frosting option, top with cream cheese frosting after cooling completely.

Your questions, answered
Can I make these bars the day before serving?
Yes — they’re actually better the next day. The spices deepen overnight and the texture firms up just enough to slice cleanly. Bake, cool completely, frost, cover tightly, and refrigerate; pull them out about 30 minutes before serving so they’re not fridge-cold.
Can I double the recipe?
You can, but use two 9×13 pans rather than one larger pan. Spreading a doubled batch too thick in a single pan changes the bake time unpredictably and often leaves the center underdone. Rotate the pans halfway through baking.
My bars came out dense and gummy in the middle — what went wrong?
The most likely cause is too much pumpkin puree or under-baking. Measure the puree in a liquid measuring cup and level it off; some cans settle and a heaping cup adds significant extra moisture. Also confirm your oven temperature with an inexpensive oven thermometer — ovens that run cool are a common culprit.
Do I have to use cream cheese frosting, or is there another option?
The bars are completely fine served plain or with a light dusting of powdered sugar. If you want a frosting that’s more stable at room temperature for an outdoor event, a simple vanilla buttercream holds up better than cream cheese frosting, which softens quickly above 70°F.
