16 Irresistible Pumpkin Chocolate Chip Bars

These pumpkin chocolate chip bars are what happen when a brownie and a blondie fall in love with pumpkin spice season. They’re dense, fudgy, and studded with melty chocolate in every square. One bowl, one pan, and about 45 minutes is all it takes.

Why You’ll Love This Pumpkin Chocolate Chip Bars

• One bowl, no mixer needed — melted butter does all the work.
• Dense, brownie-like texture with warm pumpkin spice in every bite.
• Ready in under an hour, so they’re an easy last-minute fall treat.

Ingredients You’ll Need

• Unsalted butter, melted — gives these bars their dense, brownie-like texture instead of a cakey crumb.
• Pumpkin pie spice — blooms in the warm butter for a deeper, more fragrant spice flavor.
• Brown and granulated sugar — the mix adds moisture and a hint of caramel sweetness.
• Pumpkin puree — use pure pumpkin, not pie filling, which is pre-sweetened and too wet for this batter.
• All-purpose flour — just enough to hold the bars together without making them cakey.
• Semisweet chocolate chips — divided between the batter and the top for pockets of chocolate in every square.

How to Make Pumpkin Chocolate Chip Bars

1. Preheat and prep the pan. Preheat oven to 350°F and line a 9×13-inch pan with parchment, leaving an overhang on the sides.
2. Toast the spice. Whisk 1 tablespoon pumpkin pie spice into ¾ cup melted butter and let it sit for 1 minute to bloom the spices.
3. Mix the wet ingredients. Whisk in 1 cup brown sugar, ½ cup granulated sugar, 1 cup pumpkin puree, 1 egg, 2 teaspoons vanilla, and ½ teaspoon salt until smooth.
4. Add the dry ingredients. Fold in 2 cups flour and 1 teaspoon baking powder just until no dry streaks remain — don’t overmix or the bars turn cakey.
5. Fold in the chocolate. Stir in 1¼ cups chocolate chips, spread the batter into the pan, and scatter the remaining ¼ cup chips on top.
6. Bake. Bake at 350°F for 26-30 minutes, until a toothpick comes out with a few moist crumbs but no wet batter.
7. Cool completely. Let the bars cool at least 30 minutes in the pan before lifting out and slicing into 16 squares — they firm up as they cool.

Tips for Success

Don’t skip the melted butter. It’s what gives these pumpkin chocolate chip bars their dense, brownie-like texture instead of a cakey crumb. Melt it just until liquid, not hot enough to cook the egg later.

Underbake slightly. Pull the pan when the center still looks a touch underdone — carryover heat finishes the bake and keeps the middle fudgy.

Use pure pumpkin, not pie filling. Pie filling is pre-sweetened and spiced, which throws off the texture and makes the bars too wet.

Variations to Try

• Swap half the chocolate chips for chopped pecans or walnuts.
• Add a cream cheese swirl before baking for a marbled version, like the topping in these pumpkin bars with cream cheese frosting.
• Use white chocolate chips instead of semisweet for a sweeter bar.
• Stir in ½ teaspoon espresso powder to deepen the chocolate flavor.

What to Serve With Pumpkin Chocolate Chip Bars

These bars are rich enough to stand alone with a glass of cold milk, but a scoop of vanilla ice cream turns them into a full dessert. For a fall bake sale spread, set them out next to these pumpkin pie cupcakes and let people choose.

A warm mug of spiced coffee or chai is my favorite pairing on a cool afternoon.

Frequently Asked Questions

Can I make pumpkin chocolate chip bars ahead of time?

Yes, they actually taste better the next day once the flavors settle. Store them covered at room temperature for up to 3 days.

Can I freeze these bars?

Absolutely. Wrap cooled, unsliced bars tightly and freeze up to 3 months. Thaw at room temperature for a couple hours before slicing.

Why are my bars cakey instead of fudgy?

Overmixing the batter after adding the flour builds too much gluten, which makes bars rise and turn cakey. Stir just until the flour disappears.

Can I use a different size pan?

An 8×8-inch pan works too, but the bars will be thicker and need about 10 extra minutes of bake time — check for moist crumbs on a toothpick.

Final Thoughts

These pumpkin chocolate chip bars hit that sweet spot between a brownie and a blondie, with just enough pumpkin spice to make them feel like fall. They come together in one bowl, which makes them one of my most-requested treats this time of year.

Give them a try this weekend — I think they’ll become a new favorite in your house too.
