  • 3/4 cup light brown sugar, packed
  • 1/3 cup granulated sugar
  • 2 large eggs, room temperature
  • 1/2 cup neutral oil (canola, grapeseed, or light olive)
  • 2 teaspoons pure vanilla extract
  • 2 tablespoons milk (dairy or unsweetened non-dairy)
• Chocolate Swirl:
  • 4 ounces dark or semi-sweet chocolate, chopped (or chips)

Let’s Get Cooking – Instructions

1. Prep the pan: Heat oven to 350°F (175°C). Line a 9×9-inch pan with parchment, leaving overhang for easy lifting. Lightly grease.
2. Whisk the dry: In a bowl, whisk flour, baking powder, baking soda, salt, cinnamon, nutmeg, cloves, and ginger.

   Set aside.

3. Mix the wet: In a larger bowl, whisk pumpkin puree, brown sugar, granulated sugar, eggs, oil, vanilla, and milk until smooth and glossy.
4. Combine: Add dry ingredients to wet. Stir gently until just combined. Don’t overmix unless you like rubbery bars (you don’t).
5. Make the chocolate swirl: Melt chocolate with butter (or coconut oil) in a microwave-safe bowl in 20–30 second bursts, stirring until smooth.

   Stir in cocoa powder if using.

6. Assemble: Spread pumpkin batter evenly in the pan. Dollop the melted chocolate in 6–8 spoonfuls across the top. Use a knife or skewer to drag figure-8 swirls.

   Keep it artsy, not chaotic.

7. Bake: 22–28 minutes, until the center is set and a toothpick comes out with a few moist crumbs (not wet batter). Edges will look slightly pulled from the sides.
8. Cool: Let cool in the pan on a rack at least 30–45 minutes. Lift out using parchment.

   Slice into 16 squares (or 9 if you’re feeling generous with yourself).

9. Finish (optional): Sprinkle flaky sea salt while still slightly warm for a sweet-salty pop.

Keeping It Fresh

• Room temp: Store in an airtight container for 2–3 days. Place parchment between layers to protect the swirl.
• Refrigerator: Keeps 5–6 days. The texture firms up; a quick 10-second microwave brings back the cozy.
• Freezer: Wrap bars individually and freeze up to 2 months.

  Thaw at room temp or warm briefly to revive.

• Pro tip: Don’t refrigerate uncovered—fridges are basically moisture thieves.

Why This is Good for You

• Pumpkin power: Rich in beta-carotene (vitamin A), supporting vision, skin, and immune function.
• Spice benefits: Cinnamon and ginger bring antioxidant and anti-inflammatory perks. Flavor with function, IMO.
• Dark chocolate: Flavanols can support heart health. Plus, it satisfies chocolate cravings with fewer bites.
• Better balance: Oil keeps it moist with less saturated fat than butter-heavy bars.

Common Mistakes to Avoid

• Using pumpkin pie filling: It’s pre-sweetened and spiced.

  You’ll end up with chaos in a pan.

• Overmixing the batter: Leads to tough bars. Stir until the flour just disappears—then stop.
• Overbaking: Pull them when the center is set but still tender. Dry pumpkin bars are a crime.
• Swirl overload: Over-swirling blends everything into beige.

  Two or three passes is plenty.

• Skipping the cool time: Cutting too soon will smear the chocolate and crumble the edges.

Alternatives

• Gluten-free: Use a 1:1 gluten-free baking blend with xanthan gum. Check for doneness a couple minutes early.
• Dairy-free: Swap milk for almond or oat milk and use coconut oil in the chocolate.
• Refined sugar-light: Use coconut sugar for both sugars; expect a slightly deeper, caramel-like flavor.
• Spice swap: Sub 2–2.5 teaspoons pumpkin pie spice for the listed spices if that’s what you’ve got.
• Add crunch: Fold in chopped pecans or walnuts. Toast them first for maximum wow.
• Cream cheese swirl: Mix 6 oz softened cream cheese, 2 tbsp sugar, 1 tsp vanilla.

  Dollop along with the chocolate for a triple swirl moment.

• Sheet pan for a crowd: Double the recipe for a 9×13 pan. Bake 28–35 minutes, keeping an eye on the center.

FAQ

Can I use white chocolate for the swirl?

Yes, but it’s sweeter and can brown faster. Use 4 ounces white chocolate with 1 tablespoon oil, melt gently, and swirl lightly.

A pinch of salt helps balance the sweetness.

What if I only have pumpkin pie spice?

Use 2 to 2.5 teaspoons pumpkin pie spice and skip the individual spices. Still delicious, still cozy.

Do I need a stand mixer?

Nope. A whisk and spatula do the job just fine.

Overmixing is the enemy, so manual mixing is actually a plus here.

How do I know they’re done?

Look for edges pulling slightly from the pan and a center that’s set. A toothpick should come out with a few moist crumbs, not wet batter. If it’s bone-dry, you went too far.

Can I make these ahead?

Absolutely.

Bake the day before and store covered at room temp. The flavors deepen overnight—FYI, they slice cleaner on day two.

Can I reduce the sugar?

You can cut total sugar by about 20% without wrecking texture. Beyond that, they’ll get drier and less tender.

What if my swirl sank?

Your chocolate was probably too hot and thin.

Let it cool a minute before dolloping, and avoid heavy-handed swirling.

In Conclusion

These Chocolate Swirl Pumpkin Bars are the rare combo of simple process, gorgeous payoff, and flavor that hits from the first bite. Warm spices, tender crumb, and ribbons of rich chocolate make them weekday-easy and weekend-worthy. Make a pan for a gathering, for gifting, or—no judgment—for your snack stash.

Cut big squares, brew something hot, and let the compliments roll in. Your only problem now? They vanish fast—so you might as well bake two.
