One-Bowl Fudgy Pumpkin Brownies Recipe

I’ve been working on a cake recipe for the past couple of weeks, but until that one is ready, here’s a simple seasonal treat: One Bowl Fudgy Pumpkin Brownies.

With Halloween just days away, brownies feel more appropriate than cake this week. If you want something straightforward and seasonal without the fuss of decorations, these pumpkin brownies fit the bill. They combine chocolate and pumpkin puree with a touch of pumpkin spice to create a fudgy, glossy texture that sits somewhere between a flourless chocolate cake and a pumpkin pie.

As someone who blogs about baking, I’ve learned I don’t always have time to make old favorites as often as I once did. Some recipes are repeated in our house less frequently than before, but one thing I’ve noticed is that when a recipe is easy and well-liked, my family will keep making it even when I’m busy. That’s exactly what happened with a variation I adapted from a zucchini brownie recipe earlier in the year.

That zucchini brownie was a family favorite all summer: quick to make, easy to adapt, and freezer-friendly. My husband and kids actually took over the kitchen and made several double batches because we had so much zucchini. They froze well, and we kept them on hand for quick treats or unexpected guests. After seeing how well that version worked, I wondered if pumpkin puree could replace the zucchini to create a fall-friendly, one-bowl brownie without needing a food processor.

The idea was simple: replace the zucchini with canned pumpkin puree, add pumpkin pie spice, use mini chocolate chips, and mix everything in one bowl. I baked a first test batch and left my family to sample it while my husband and I attended an evening event. I asked them to note their thoughts on texture, spice level, and whether the espresso powder was noticeable.

When we returned, the feedback was enthusiastic. Both kids and adults loved them and asked not to change a thing. I often find recipe testing tedious because sampling the same flavor repeatedly grows tiring, so praise like that is a welcome relief. Later that night, after homework and bedtime, my husband and I finally tried the brownies ourselves with coffee and tea. I expected to like them, but I hadn’t anticipated his excitement.

He described the experience as tasting pumpkin and chocolate at the same time — the brownies reminded him of biting into pumpkin pie while still being unmistakably a brownie. That balance of flavors, along with a moist, fudgy but fully baked texture, made them a hit in our house. They’re less sweet than some brownies, glossy on top, and dense and fudgy within.

Because everyone enjoyed them so much, I made another batch to photograph and share. These One Bowl Fudgy Pumpkin Brownies are perfect for the season — easy to prepare, full of pumpkin flavor, and reliably delicious. If you like, you can always decorate them for holidays, but they’re just as satisfying plain.

One Bowl Fudgy Pumpkin Brownies

Yield: 16 brownies

Different brands of canned pumpkin vary in moisture. If your pumpkin is very thick, thin it with a bit of water before measuring so you end up with the correct consistency.

Ingredients

  • 8 ounces (about 3/4 cup) canned pumpkin puree (not pumpkin pie filling)
  • 3 tablespoons salted butter, melted
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 3/4 cup sugar
  • 2/3 cup unsweetened Dutch-process cocoa powder
  • 1/2 teaspoon espresso powder
  • 1 teaspoon pumpkin pie spice
  • 1/2 teaspoon baking powder
  • Heaping 1/4 teaspoon salt
  • 1/2 cup all-purpose flour
  • 3/4 cup mini chocolate chips

Instructions

  1. Preheat the oven to 350°F (175°C). Line an 8″ square pan with foil and spray lightly with cooking spray for easiest removal.
  2. In a large mixing bowl, whisk together the pumpkin puree, melted butter, eggs, and vanilla until smooth and fully combined.
  3. Add the sugar, cocoa powder, espresso powder, pumpkin pie spice, baking powder, flour, and salt. Whisk or stir until the batter is uniform and no streaks remain.
  4. Fold in the mini chocolate chips.
  5. Pour the batter into the prepared pan and spread it evenly.
  6. Bake for 25–35 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs attached. There should be no wet batter clinging to the toothpick.
  7. Allow the brownies to cool. Use the foil to lift them from the pan and cut into squares. For the cleanest slices, chill briefly before cutting.

Notes

You can use a 9″ pan for thinner brownies; check for doneness closer to 25 minutes. If doubling the recipe for a 13×9″ pan, bake time may increase to 35–45 minutes—check at 35 minutes and add time as needed.

Different cocoas yield different flavor profiles. Dutch-processed cocoa tends to give a deeper, smoother chocolate flavor, while regular unsweetened cocoa will also work.

These brownies are enjoyable at room temperature, but many prefer them chilled. For the best, clean cuts, warm a knife under hot water, dry it, and slice, reheating the blade between cuts as necessary.
