These healthy pumpkin brownies are rich, fudgy, and made in one bowl with pumpkin puree, natural peanut butter, and cocoa powder, with no flour and no oil in the batter. Maple syrup sweetens them, chocolate chips melt into every square, and a two ingredient chocolate drizzle finishes them off. The batter comes together in 10 minutes and bakes in about 25, so a pan of fall brownies can be cooling on your counter well before dinner.


My Fall Brownie Without the Flour
Pumpkin in dessert was never strange to me. Growing up in Brazil, doce de abóbora, a slow cooked pumpkin sweet, was always part of our family celebrations. When I moved to Canada and found canned pumpkin puree on every grocery shelf each fall, I started folding it into everything, and brownies were the experiment that stuck.
What makes this version different is that there is no flour and no oil to lean on. Natural peanut butter gives the brownies their fat and structure, and the pumpkin puree keeps them moist the way oil normally would. I’ll be honest about the flavor, too. These taste like a rich chocolate peanut butter brownie with a soft, warm pumpkin background, not like pumpkin pie. If you have made my flourless chocolate chip brownies, think of this as their fall version.
I bake a pan almost every week once October arrives. They are the dessert I bring to Canadian Thanksgiving, and they sit nicely next to my pecan pie brownies when I want two very different brownies on the same table. This recipe uses less than half a can of pumpkin, so I usually bake my pumpkin chocolate chip bread the same afternoon to use up the rest.
Key Ingredients
All ingredients and their amounts are listed in the recipe card at the bottom of this post.
Pumpkin Puree: You need ¾ cup, which is a little less than half of a standard 15 ounce can. Make sure the label says 100% pumpkin and not pumpkin pie filling, which already has sugar and spices and will make the brownies sweet and gummy. I’ve made this recipe with canned pumpkin and with my homemade pumpkin puree, and both work. Homemade is usually wetter, so if yours looks loose, spread it on a few paper towels for 10 minutes before measuring. Watery puree is the most common reason pumpkin brownies stay gummy in the middle.
Pro Tip: Freeze any leftover canned pumpkin in ¾ cup portions. Your next batch of brownies is then already measured.
Natural Peanut Butter: This is the ingredient doing the most work here, since it replaces both the flour and the oil. I recommend a natural peanut butter made with just peanuts and salt, and I like to stir it really well before measuring. The oil that separates on top makes brownies greasy, and the dry paste at the bottom of the jar makes them crumbly. I’ve tested this with almond butter too. It works well, the brownies are just a little milder and slightly less rich. For a nut free version, sunflower seed butter works, but it can turn the inside of the brownies slightly green as they cool. That’s a harmless reaction between the sunflower seeds and the baking soda, and cutting the baking soda to ¼ teaspoon helps.
Cocoa Powder: I use regular unsweetened cocoa powder, also called natural cocoa. Its natural acidity reacts with the baking soda and gives these brownies their small lift. Dutch process cocoa will still work and gives a darker color, but expect a denser, flatter brownie.
Maple Syrup: Pure maple syrup is my first choice. It sweetens the batter and adds moisture at the same time, and its flavor goes beautifully with pumpkin. Honey works as a 1 to 1 swap, but it browns faster, so I start checking the brownies a few minutes early. I don’t recommend replacing it with granulated sugar because the batter depends on a liquid sweetener to stay soft.
Chocolate Chips: I use semi sweet or dark chocolate chips, both in the batter and for the drizzle on top. They are where most of the sweetness in these brownies comes from, so choose a chocolate you love eating on its own. One reader made this recipe with monk fruit sweetened chocolate chips and date syrup instead of maple, and loved the result.
Eggs: Two large eggs, at room temperature. Without flour, the eggs are what hold these brownies together, so I don’t recommend replacing them. Cold eggs can also make the peanut butter seize slightly, which is why I take them out of the fridge while the oven preheats.

How To Make Pumpkin Brownies
Before you start: Preheat the oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving some paper hanging over two sides so you can lift the brownies out in one piece later.
1. Mix the pumpkin and peanut butter. In a large mixing bowl, I whisk the peanut butter and pumpkin puree together until completely smooth. Peanut butter is thick, and getting it fully blended with the pumpkin now means you won’t find streaks of it in the finished brownies.
2. Add the eggs, maple syrup, and vanilla. I whisk in the eggs first, one at a time, then stir in the maple syrup and vanilla extract. The batter should turn glossy and loose. That shine tells you the eggs are fully mixed in and will bind the brownies properly.


3. Add the dry ingredients. In a small bowl, I stir the cocoa powder, baking soda, and salt together before adding them. This breaks up little clumps of baking soda, which otherwise leave bitter pockets in the brownies. I mix only until no dry cocoa remains. The batter will be very thick, almost like frosting, and overmixing at this point makes the brownies tough.
4. Fold in the chocolate chips and spread. I gently fold in the chocolate chips, then spread the batter into the prepared pan. Because it is so thick, a spatula dipped in a little water makes spreading it into the corners much easier. I sprinkle a few extra chocolate chips over the top so you get melted chocolate in every bite.


5. Bake. I bake the brownies for 22 to 25 minutes. They are ready when the edges pull away slightly from the pan and the center looks set but still has a little give when you gently press it. A toothpick inserted in the center should come out with a few moist crumbs, not wet batter. Melted chocolate from a chip doesn’t count, so test a second spot if you hit one.
6. Cool completely before cutting. This step matters more than in a regular brownie. Without flour, these brownies are very soft right out of the oven and only firm up as they cool. I let them cool in the pan for at least 30 minutes, then lift them out with the parchment and cut them into 9 squares.


7. Make the chocolate drizzle. I melt the chocolate chips with the butter in the microwave in 30 second bursts, stirring in between, until smooth. Then I drizzle it over the brownies with a spoon. Going in short bursts keeps the chocolate from scorching.
Olivia’s Baking Tips
Glass and silicone pans need more time. I bake these in both metal and silicone pans, and anything other than metal usually needs an extra 3 to 5 minutes. Check the center rather than the clock.
Warm or cold, they are two different brownies. Slightly warm, the center is soft and almost pudding like. Straight from the fridge, they turn dense and fudgy, which is how I like them best.
Turn up the pumpkin spice. If you want the pumpkin to come forward more, add 1 teaspoon of pumpkin pie spice, or a mix of cinnamon, ginger, and nutmeg, with the cocoa powder.
Doubling the recipe. Double every ingredient and bake in a 9×13 inch pan. Start checking at 28 minutes, since the thicker layer takes longer to set.

Make Ahead and Storage
These pumpkin brownies are one of my favorite make ahead desserts because they actually taste better on day two, once the chocolate and pumpkin have had time to settle together.
For Thanksgiving, I bake them the day before, keep them covered in the fridge, and add the chocolate drizzle the morning I serve them. If you plan to freeze them, freeze them without the drizzle and add it after they thaw in the fridge overnight.

I am on an insulin resistant diet plan and this dessert worked so well for me with a few substitutions. The chocolate chips I used are sweetened with monk fruit sweetener, and instead of honey I use date syrup. I also added a half a cup of crushed walnuts to the batter before pouring it into my pan. It’s hard to believe there is no flower in this recipe. It’s absolutely delicious and is my new go to brownie recipe. Thank you so much for sharing it with us!
