A pan of these bars disappears faster than almost anything else I bring to a fall potluck.
I started making these when I wanted a pumpkin dessert that fed a crowd without needing to slice individual muffins or a loaf. This is essentially a soft, spiced pumpkin sheet cake, topped edge to edge with a thick layer of cream cheese frosting and cut into neat squares.
It’s simple, it travels well, and it’s the kind of dessert that gets requested by name once people have tried it.
Let’s bake a pan.
What You’ll Need
For the pumpkin bars:
- 2 cups all purpose flour
- 2 tsp baking powder
- 1 tsp baking soda
- 2 tsp ground cinnamon
- ½ tsp ground nutmeg
- ¼ tsp ground cloves
- ½ tsp salt
- 4 large eggs
- 1 ⅔ cups granulated sugar
- 1 cup vegetable oil
- 15 oz canned pumpkin puree
For the cream cheese frosting:
- 8 oz cream cheese, softened
- ½ cup butter, softened
- 3 cups powdered sugar
- 1 tsp vanilla extract
- Ground cinnamon, for dusting
A simple sheet cake style bar recipe that feeds a crowd without much extra effort.
Tools You’ll Need
- 9×13 inch baking dish
- Mixing bowls
- Whisk
- Electric mixer or hand mixer
- Offset spatula, for frosting
Pro Tips
I’ve made these bars enough falls to know exactly what makes them turn out right.
1. Use pure pumpkin puree, not pumpkin pie filling. Pie filling already contains added sugar and spices, which will throw off the balance of this recipe.
2. Don’t overmix the batter. Stir just until combined, since overmixing can make these bars dense instead of soft and tender.
3. Let the bars cool completely before frosting. Warm bars will melt the cream cheese frosting right off instead of holding a nice, even layer on top.
4. Use fully softened cream cheese and butter for the frosting. Cold ingredients leave lumps that won’t smooth out, no matter how long you beat them.
5. Chill the frosted bars briefly before slicing. This helps the frosting set slightly, giving you cleaner cuts instead of frosting smearing across the knife.
How to Make Pumpkin Bars with Cream Cheese Frosting
Step 1: Mix the Dry Ingredients
Preheat your oven to 350°F and grease a 9×13 baking dish.
Whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, cloves, and salt in a bowl.
Step 2: Mix the Wet Ingredients
In a separate bowl, whisk together the eggs, sugar, oil, and pumpkin puree until smooth.
Step 3: Combine
Add the dry ingredients to the wet mixture, stirring just until combined.
Step 4: Bake
Pour the batter into the prepared baking dish and spread evenly.
Bake for 25 to 30 minutes, until a toothpick inserted comes out clean.
Let cool completely.
Step 5: Make the Frosting
Beat the softened cream cheese and butter together until smooth.
Add the powdered sugar and vanilla extract, beating until fluffy.
Step 6: Frost and Serve
Spread the frosting evenly over the cooled bars.
Dust with a light sprinkle of ground cinnamon, then slice into squares.
Substitutions and Variations
- Nut addition: Fold ½ cup chopped pecans or walnuts into the batter for extra texture.
- Maple frosting: Swap the vanilla extract in the frosting for maple extract for a different flavor twist.
- Gluten free: Use a 1:1 gluten free flour blend in place of all purpose flour.
- Dairy free: Use a dairy free butter and cream cheese alternative throughout.
- Spiced glaze version: Skip the cream cheese frosting and drizzle with a simple powdered sugar glaze for a lighter finish.
Make Ahead Tips
Bake the bars up to 2 days ahead and store unfrosted, covered at room temperature.
The frosting can also be made a day in advance and stored in the fridge, then brought to room temperature and rewhipped before spreading.

Diet Friendly Swaps
- Lower sugar: Reduce the sugar slightly in both the bars and frosting.
- Gluten free: Use a 1:1 gluten free flour blend throughout.
- Dairy free: Use dairy free butter and cream cheese alternatives.
Meal Pairing Suggestions
Serve alongside a cup of coffee or chai tea for a cozy fall treat.
These also work well as part of a larger fall dessert table alongside pumpkin cookies or apple cider donuts.
Cooking Time Efficiency Tips
Make the frosting while the bars cool, so both components are ready to combine at the same time.
Bake in a 9×13 pan for a single batch that feeds a crowd, rather than making individual portions that take more hands on time.
Leftovers and Storage
Store frosted bars in an airtight container in the fridge for up to 5 days, since the cream cheese frosting needs refrigeration.
These freeze well too, either frosted or unfrosted. Wrap tightly and freeze for up to 2 months, thawing in the fridge before serving.
FAQ
Why did my bars turn out dense instead of soft? This usually means the batter was overmixed, or too much flour was added. Measure carefully and mix just until the ingredients are combined.
Can I use fresh pumpkin instead of canned? Yes, just make sure it’s well drained and pureed smooth, since fresh pumpkin can contain more moisture than canned puree.
Do these bars need to be refrigerated? Yes, once frosted, they should be stored in the fridge because of the cream cheese frosting.
Can I make these bars ahead for a party? Yes, bake them a day or two in advance and frost the day of or the day before serving for the best presentation.
Can I double this recipe? Yes, though you’ll need two 9×13 pans, since doubling in one pan would make the layer too thick to bake evenly.
Wrapping Up
These pumpkin bars bring soft, spiced comfort in an easy sheet cake format that’s simple to slice, serve, and share with a crowd.
Once you make a pan, it becomes the dessert you’re expected to bring to every fall gathering from here on out.
