Pumpkin Bars with Cream Cheese Frosting You Will Love

These Pumpkin Bars with Cream Cheese Frosting are the autumn bake that lands between a pumpkin cake and a pumpkin brownie in the best possible way — a thick, incredibly moist, warmly spiced pumpkin sponge baked in a sheet pan until just set, cooled completely, and then covered with a generous, tangy-sweet cream cheese frosting that is thick enough to hold a swirl and flavoured with vanilla and just enough cinnamon to make it taste specifically of autumn rather than just cream cheese.

The recipe is written for a 9×13 inch pan with a note for jelly roll pan quantities, and includes five variations covering pumpkin cheesecake bars, pumpkin pie bars, pumpkin spice bars, a healthy lightened version, and a gluten-free adaptation.

Why Pumpkin Makes the Moistest Bars

Canned pumpkin purée in a bar or cake batter functions identically to applesauce or mashed banana — it contributes moisture, fibre, and natural sweetness while replacing some of the fat required in a conventional cake. The result is a bar that stays moist for significantly longer than a butter-only bar, with a slightly denser, more fudgy crumb that is the specific texture that makes pumpkin bars satisfying rather than just another spiced baked good.

A full 15 oz can of pumpkin purée in a 9×13 pan recipe is the quantity that produces the moistest bars — some recipes use less and produce a bar that is noticeably drier and more cake-like. The full can is the correct amount; do not reduce it to compensate for any instinct that it seems like a lot.

• Prep Time: 20 minutes
• Cook Time: 25 to 30 minutes
• Cool and Frost Time: 1 hour
• Total Time: approximately 1 hour 50 minutes
• Yield: 24 bars (9×13 pan)

What You Need

For the pumpkin bars:

• All-purpose flour: 2 cups (250g)
• Baking powder: 1 1/2 teaspoons
• Baking soda: 1 teaspoon
• Fine sea salt: 1/2 teaspoon
• Ground cinnamon: 2 teaspoons
• Ground nutmeg: 1/2 teaspoon
• Ground ginger: 1/2 teaspoon
• Ground cloves: 1/4 teaspoon
• Ground allspice: 1/4 teaspoon
• Granulated sugar: 1 cup (200g)
• Light brown sugar, packed: 1/2 cup (100g)
• Canned pumpkin purée (not pumpkin pie filling): 1 can (15 oz / 425g)
• Neutral oil (vegetable or avocado): 3/4 cup (180ml) — oil produces a moister bar that stays soft at room temperature longer than butter; butter firms when cold and makes the bars noticeably denser from the fridge
• Large eggs: 4
• Pure vanilla extract: 1 1/2 teaspoons

For the cream cheese frosting:

• Cream cheese, softened to room temperature: 8 oz (225g) — full-fat only; reduced-fat cream cheese produces a looser, less stable frosting that doesn’t hold its swirl
• Unsalted butter, softened: 4 tablespoons (56g)
• Powdered sugar, sifted: 2 1/2 cups (300g)
• Pure vanilla extract: 1 teaspoon
• Ground cinnamon: 1/4 teaspoon
• Fine sea salt: a pinch
• Heavy cream or whole milk: 1 to 2 tablespoons, to adjust consistency

How to Make Them

Making the pumpkin bars:

1. Preheat the oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving overhang on the long sides to lift the bars out after cooling. Grease the parchment.
2. Whisk the flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, cloves, and allspice together in a large bowl until completely combined.
3. In a separate large bowl, whisk the granulated sugar, brown sugar, pumpkin purée, oil, eggs, and vanilla together until smooth and uniform — whisk for a full 60 seconds to ensure the sugars dissolve and the mixture emulsifies evenly.
4. Pour the wet ingredients into the dry and fold with a spatula until just combined — 12 to 15 strokes, stopping the moment no dry flour streaks remain. The batter will be smooth, slightly thick, and orange-brown from the pumpkin. Do not over-mix.
5. Pour into the prepared pan and spread into an even layer — the batter is thick enough to need spreading rather than flowing to the edges on its own.
6. Bake at 350°F for 25 to 30 minutes until the top is set and a toothpick inserted in the center comes out with moist crumbs but no wet batter. The bars will look slightly underdone when they come out of the oven — this is correct and preferred; they continue cooking from residual heat and firm as they cool. Overbaked pumpkin bars are dry; slightly underbaked ones are perfectly moist.
7. Cool completely in the pan on a wire rack before frosting — at least 1 hour, preferably 2. Warm bars melt the cream cheese frosting into a liquid that runs off the surface rather than sitting in a thick, swirled layer. Do not rush this step.

Making the cream cheese frosting:

1. Beat the softened cream cheese and softened butter together with a hand mixer or stand mixer on medium speed for 2 to 3 minutes until completely smooth, pale, and fluffy — both must be fully room temperature or the frosting will have small lumps of cold cream cheese that cannot be beaten out.
2. Add the sifted powdered sugar in two additions, beating on low after each addition until incorporated, then increasing to medium for 30 seconds. Add the vanilla, cinnamon, and salt.
3. Add heavy cream or milk 1 teaspoon at a time until the frosting reaches the right spreadable consistency — thick enough to hold a swirl when a spoon is dragged through it but soft enough to spread easily. A slightly stiffer frosting produces a cleaner cut; a slightly softer frosting produces a more elegant spread.
4. Spread the frosting over the completely cooled bars in a thick, even layer — use an offset spatula or the back of a large spoon for a smooth surface, or swirl deliberately for a more rustic, textured look. The frosting layer should be generous — these bars earn their name from the frosting as much as the pumpkin.
5. Refrigerate for 30 minutes before cutting to set the frosting and produce clean, sharp-edged bar cuts. Use a large sharp knife wiped clean between cuts for the most professional-looking squares.

Pumpkin bars with cream cheese frosting and our Pumpkin Spice Bread Loaf together are the autumn baking project that makes a weekend in October feel perfectly spent — the bread loaf for slicing and eating through the week, the bars for serving at any gathering that happens between now and Thanksgiving. Both from the same can of pumpkin, both better on day two.

The Oil-Not-Butter, Full Can, and Cool Completely Rules

Oil rather than butter in the bar batter is the choice that produces a bar that is soft and moist both fresh and cold from the fridge — butter contains approximately 20 percent water that evaporates during baking and solidifies at refrigerator temperatures, producing a bar that is noticeably firmer and drier when served cold. Oil maintains its liquid state at all temperatures, keeping the crumb soft and moist whether the bars are served at room temperature or straight from the fridge. For a bar that is eaten over several days at various temperatures, oil is the correct choice.

Slightly underbaking — pulling the bars when the toothpick comes out with moist crumbs rather than clean — is the technique that produces the fudgy, moist interior that defines the best pumpkin bars. The carryover cooking from the residual heat in the pan finishes the bars as they cool, and the result is a center that is fully set but still densely moist. A clean-toothpick pull produces bars that are fully baked but noticeably drier. When in doubt, take them out a minute early.

Cooling completely before frosting is the rule that requires the most patience and produces the most dramatic quality difference — cream cheese frosting spread over even slightly warm bars melts from a thick, stable layer into a thin, translucent glaze that runs to the edges and produces bars that look nothing like the thick-frosted version that is the appeal of the recipe. Two hours of cooling is not excessive; overnight cooling before frosting produces the cleanest possible frosting application.

What to Serve These With

As a standalone dessert at room temperature with a cup of spiced apple cider or a latte, pumpkin bars with cream cheese frosting need nothing additional — they are complete and self-contained as a dessert experience.

On a dessert tray alongside our Soft Spiced Apple Cookies for an autumn dessert spread — the two recipes share the same cinnamon-nutmeg-allspice spice blend and together cover the two most beloved autumn flavours (pumpkin and apple) in formats that serve different preferences: bars for those who want a frosted, more substantial dessert, cookies for those who want something lighter and hand-held.

Five Pumpkin Bar Variations from the Same Base

Pumpkin Bars with Cream Cheese Frosting 9×13 — this is the base recipe as written, named explicitly for the most searched pan size. The 9×13 pan produces 24 bars of standard thickness and is the most practical size for a gathering or holiday dessert tray. The parchment overhang lifting method allows the entire sheet to be removed from the pan and cut cleanly on a board before returning to the pan or arranging on a platter.

Pumpkin Bars with Cream Cheese Frosting Jelly Roll Pan — use a 10×15 inch jelly roll pan for thinner bars with a higher bar-to-frosting ratio. Reduce the bake time to 18 to 20 minutes and check at 18 minutes — thinner bars bake faster and overbake quickly. The jelly roll pan version produces 32 to 40 thinner bars that are more appropriate as a finger food dessert at a large gathering where you want high bar count from a single batch.

Pumpkin Pie Bars — press a shortbread crust (1 cup flour + 1/4 cup powdered sugar + 1/2 cup cold butter, cubed and pulsed to crumbs, pressed into the 9×13 pan and baked at 350°F for 12 minutes until set) into the bottom of the pan before adding the pumpkin layer. The pumpkin layer is adapted to a custard rather than a sponge: blend 1 can of pumpkin with 1 cup of sweetened condensed milk, 2 eggs, 1 teaspoon of vanilla, and 2 teaspoons of pumpkin pie spice. Pour over the pre-baked crust and bake for 25 minutes at 350°F until set. Cool completely and serve either plain (dusted with cinnamon) or with a thin cream cheese frosting layer. These taste specifically like pumpkin pie in a hand-held bar.

Pumpkin Cheesecake Bars — make a graham cracker crust (1 1/2 cups crushed graham crackers + 1/4 cup melted butter + 2 tablespoons sugar, pressed into a parchment-lined 9×13 and baked at 325°F for 8 minutes). Beat 16 oz of softened cream cheese with 1/2 cup of sugar and 2 eggs until smooth. Spread half over the graham cracker crust. Blend 1 cup of pumpkin purée with 1 egg, 1/4 cup of sugar, and 1 teaspoon of pumpkin pie spice; spoon over the cream cheese layer. Swirl gently with a knife. Bake at 325°F for 30 to 35 minutes until set with a slight jiggle in the center. Cool completely, refrigerate for 2 hours, and cut. These are closer to a cheesecake bar than a cake bar — denser, cooler, more custardy.

Pumpkin Spice Bars (Healthy Version) — replace 1/2 cup of the oil with 1/2 cup of unsweetened applesauce, reduce the total sugar to 1 cup (using only granulated), and replace 1/2 cup of the all-purpose flour with 1/2 cup of whole wheat flour. For the frosting, use the light cream cheese frosting: 4 oz of reduced-fat cream cheese + 1/4 cup of Greek yogurt + 1 1/2 cups of powdered sugar + vanilla. The healthy version is approximately 165 calories per bar compared to the standard version’s 220 — a meaningful reduction without sacrificing the pumpkin spice flavour or the creamy frosting entirely.

Nutritional Information

These values are estimates for the full recipe with the full cream cheese frosting divided by 24 bars. The pumpkin pie bars variation reduces to approximately 185 calories per bar without the cream cheese frosting layer (and 215 with a thin frosting). The pumpkin cheesecake bars are approximately 195 calories per bar from the lighter cheesecake structure. The healthy pumpkin spice bars with lightened frosting reduce to approximately 165 calories per bar.

Storing and Keeping These at Their Best

Store covered in the fridge for up to 5 days — the cream cheese frosting requires refrigeration, and the bars are genuinely better cold from the fridge than at room temperature. The pumpkin sponge stays moist throughout the 5-day storage window because of the oil in the batter; the frosting stays firm and sliceable when cold. Remove from the fridge 15 to 20 minutes before serving if you prefer the bars at room temperature — the frosting softens slightly from the cold but the bar is equally good either way.

Freeze unfrosted bars for up to 3 months — cool completely, wrap the entire uncut slab in plastic wrap and then foil, and freeze. Thaw overnight in the fridge, frost at room temperature, then refrigerate to set the frosting before cutting and serving. Frosted bars can also be frozen individually in plastic wrap but the frosting texture changes slightly after thawing — slightly softer and less pristine than fresh-applied frosting, but perfectly acceptable for a weekday treat pulled from the freezer.

Mistakes That Produce Dry Bars or Runny Frosting

Overbaking until the toothpick comes out completely clean produces dry bars — pumpkin bars should come out of the oven when the toothpick shows moist crumbs, not wet batter but not clean. The carryover heat as they cool finishes the cooking and the result is moist rather than dry. Set a timer for 25 minutes and check early; every oven runs differently and 30 minutes may be too long in some.

Using cold cream cheese or cold butter for the frosting produces a lumpy frosting that cannot be beaten smooth regardless of how long the mixer runs — the cold fat does not incorporate into the surrounding mixture and the lumps persist as visible texture in the finished frosting. Both must be genuinely soft and at room temperature — soft enough to leave an indent when pressed with a finger — before the mixer touches them. If short on time, cut into cubes and leave at room temperature for 30 minutes.

Frosting warm bars produces a disaster — the cream cheese frosting melts on contact with any residual warmth in the bars and runs to the edges as a thin glaze rather than sitting as a thick, swirled layer. There is no fix for this after the fact; the bars must be re-cooled and then re-frosted with additional frosting. Save the patience and cool completely before beginning.
