I know, sweet potatoes in brownies might sound unusual, but you guys, they are soo good! I first tried these on a whim when I had some leftover sweet potatoes and a craving for something chocolatey – and they turned out so fudgy! The sweet potatoes also add a natural sweetness, making the brownies super rich without needing a ton of extra sugar or fat.

What I love about these sweet potato brownies is that they’re decadent but feel a little lighter. The peanut butter and chocolate chips bring out the chocolate flavor even more, while the sweet potato keeps everything moist and almost melt-in-your-mouth. If you’re in the mood for a twist on classic brownies, these are a must-try!

Ingredients to Make Sweet Potato Brownies
- All-purpose flour: You can substitute a gluten-free flour blend just get one that works at a 1:1 ratio.
- Cocoa powder: Dutch-process or natural cocoa powder will work—just know the former is milder and less bitter!
- Baking soda: This helps the brownies rise.
- Butter: Just a little butter adds flavor!
- Brown sugar: I like light brown sugar in this brownie recipe because it adds notes of molasses and caramel!
- Mashed sweet potatoes: You microwave or roast a sweet potato and mash it or use canned sweet potato puree!
- Peanut butter: I like to use creamy peanut butter because it’s easier to mix in with the rest of the ingredients! But you can use crunchy if that’s your preference.
- Vanilla: I like to use pure vanilla extract; you could even use vanilla bean paste if you wanted to.
- Chocolate chips: Semi-sweet, bittersweet, or dark chocolate chips will be fine!
Popular Substitutions & Additions
- Make it pumpkin (or squash!). Instead of the sweet potato, you could use pumpkin puree or butternut squash puree!
- Add nuts. Try topping the sweet potato brownies with chopped walnuts or toasted pecans. You could also stir them into the batter!
- Use a different nut butter. Almond butter, cashew butter, tahini, or sunflower seed butter would work in place of the peanut butter!
How to Make Sweet Potato Brownies
These easy, fudgy brownies require just a few mixing bowls and a baking pan! Most weeks, I bake whole sweet potatoes for an easy dinner side and roast an extra potato so that I can make this recipe!
Tips for Making the Best Sweet Potato Brownies
- Use a parchment paper sling. Line the baking pan with parchment paper so that the sides overhang the edges of the pan a good bit. This makes it easy to lift the brownies up and out of the pan once they’re baked!
- Test to make sure the brownies are done first. I like to use a toothpick for this! Just insert it into the center of the brownies. If the batter sticks to the toothpick, the brownies need more time in the oven. However, if just a few crumbs are on the toothpick, they’re done!
- Make the brownies more cakey than fudgy. You can do this by swapping the baking soda for baking powder!
- Don’t skip cooling. Letting the brownies rest in the pan for about 30 minutes before cooling on the wire rack helps the brownies settle and form. Allowing them to cool completely also makes them easier to cut.
Frequently Asked Questions
Kept in an airtight container, these brownies will last for up to 5 days at room temperature or a week in the fridge. I like to put layers of parchment paper in between the stacks of brownies so they don’t stick!
You can! You’ll need to use a 9 – x 13-inch baking dish and will probably have to increase the baking time! I’d just keep an eye on the brownies and check them frequently.
They shouldn’t! If they do, there’s a good chance the brownies aren’t fully cooled. You could wait or pop the brownies in the fridge to firm up faster.

Well…. You’ve done it again!! This is the only way I will make brownies forever from now on.
I made some substitutions, I have a friend who is gluten free so I used oat flour instead and I don’t eat processed sugar so I used maple syrup (so added a bit more oat flour) and it was perfect!! I can’t believe this tastes just like “normal” brownies. THANK YOU! So so amazing.
My friend is gluten and egg free so this was the most amazing recipe ♥️
