This is the dessert I bring to every fall potluck and Thanksgiving gathering. Pumpkin bars with cream cheese frosting are the fall dessert tray classic — moist, spiced pumpkin cake (think pumpkin pie meets sheet cake) topped with thick tangy cream cheese frosting. One-bowl batter, 9×13 pan, feeds a crowd of 12. Thanksgiving, Halloween, fall potluck perfection. The bars everyone fights over.
Fun fact: pumpkin bars became a fall staple in 1950s American home baking when canned pumpkin became widely available. Libby’s introduced canned pumpkin in 1929, but it didn’t gain wide popularity until WWII when fresh ingredients were rationed. By the 1960s, pumpkin bars had appeared in nearly every regional church cookbook in America. They remain one of the most-shared seasonal recipes online.
Why this recipe works
Use pumpkin puree, not pumpkin pie filling. Pie filling has added sugar and spices that throw off the ratios. Look for “100% pure pumpkin” on the can.
Don’t overmix. Stir gently just until combined. Overmixing makes dense bars instead of tender ones.
Cool completely before frosting. Warm bars + cream cheese frosting = melted mess. Wait until bars are room temp.
Ingredients
Makes 12 bars.
For the pumpkin bars
2 cups all-purpose flour
2 tsp baking powder + 1 tsp baking soda + 1/2 tsp salt
2 tsp pumpkin pie spice + 1 tsp cinnamon
4 large eggs
1 cup vegetable oil + 1.5 cups granulated sugar + 1/2 cup brown sugar
1 (15 oz) can pumpkin puree (NOT pumpkin pie filling)
2 tsp vanilla extract
For the cream cheese frosting
8 oz cream cheese, softened
1/2 cup softened butter
3 cups powdered sugar
2 tsp vanilla extract
Pinch of salt
For garnish
Dust of ground cinnamon + chopped pecans + fall sprinkles (optional)
Smart substitutions
Healthier: Whole-wheat pastry flour (half), applesauce for half the oil, reduce sugar to 1.5 cups total
Add nuts: 1 cup chopped pecans or walnuts in the batter
Add chocolate: Fold in 1 cup chocolate chips for pumpkin-chocolate bars
Instructions
Step 1: Preheat and prep the pan
Heat oven to 350°F. Grease a 9×13 baking pan and line with parchment, leaving overhang on both long sides for easy removal.
Step 2: Whisk dry ingredients
In a medium bowl, whisk flour, baking powder, baking soda, salt, pumpkin pie spice, and cinnamon.
Step 3: Mix wet ingredients
In a large bowl, whisk eggs, oil, both sugars, pumpkin puree, and vanilla until completely smooth.
Step 4: Combine wet and dry
Add dry mixture to wet; whisk gently just until smooth — about 30 seconds. Don’t overmix.
Step 5: Bake the bars
Pour batter into the prepared pan, smoothing the top. Bake 28-32 minutes until a toothpick inserted in the center comes out clean. Cool completely in the pan on a wire rack — this is critical for frosting.
Step 6: Make frosting and decorate
Beat softened cream cheese and butter for 2 minutes until smooth. Add powdered sugar a half-cup at a time until fluffy. Beat in vanilla and salt. Spread generously over cooled bars. Sprinkle with cinnamon, chopped pecans, or fall sprinkles. Lift bars out using parchment overhang. Cut into 12 squares with a sharp knife (wipe between cuts for clean slices).

Pro tips
Make ahead: Bake bars 1-2 days before, frost the day of serving. Frosting is best fresh.
Cute decorations: Use orange and brown sprinkles, candy pumpkins, or a stencil with cocoa powder for fall designs.
Mini muffins version: Same batter in mini muffin pan, bake 18-20 min, top with frosting after cooling. Perfect for kids.
Freezer-friendly: Freeze unfrosted bars (whole pan or individual squares) up to 3 months. Frost after thawing.
Frequently asked questions
What’s the difference between pumpkin puree and pumpkin pie filling?
Pumpkin puree is just pumpkin (sometimes labeled “100% pure pumpkin”). Pumpkin pie filling has sugar, spices, and thickeners added. Always use pure pumpkin puree in baking — Libby’s is the most reliable brand.
How do I store them?
Refrigerator for up to 5 days, covered. Room temperature for 2 days. Freeze up to 3 months — thaw overnight in fridge.
Can I use fresh pumpkin instead of canned?
Yes — roast a small sugar pumpkin (about 3 lbs) at 400°F for 45 minutes, scoop out flesh, puree until smooth. You’ll get about 2 cups. Drain any excess liquid first.
Why is my cream cheese frosting too runny?
Cream cheese was probably too warm or butter was melted. Chill the frosting 30 minutes in the fridge and re-whip. Or add more powdered sugar 1/4 cup at a time until it firms up.
Can I make them gluten-free?
Yes — substitute 1:1 GF flour blend (King Arthur’s GF works perfectly) plus 1 tsp xanthan gum. Texture is slightly more delicate but still excellent.
What’s pumpkin pie spice if I don’t have it?
Make your own: 2 tsp cinnamon + 1 tsp ginger + 1/2 tsp nutmeg + 1/4 tsp cloves + 1/4 tsp allspice. Adjust to taste.
