You’ll find it extremely difficult to only have one of these super-moist and fudgy brownies. Their fudge-like texture and gorgeous peanut-butter swirl make them positively irresistible!
If a huge peanut butter swirl in my brownies is wrong, then I don’t ever want to be right.
I also never ever want to stop eating these brownies. So dark and chocolate-y. So dense and fudgy. And OMG that peanut butter swirl!
These brownies are The. Bomb. Seriously, each bite tastes like pure, decadent fudge with a twist of peanut butter. Pure awesomeness.
Put down that boxed brownie mix, because you are never going to want to go back to brownies-from-a-box ever again. These homemade brownies are completely fool-proof and 1000x better than the boxed stuff. Did I mention they take only 30 minutes?? Oh, and they’re healthier too. That’s always a plus.
Obviously because that means you can eat more of ’em. 😉
The batter for these brownies is fairly simple, but all of the ingredients are important, and I wouldn’t recommend subbing any of them. You’ll need to grab your flour (I used white whole-wheat) unsweetened cocoa powder, salt, oil, coconut sugar, (if you need to, brown sugar would be a perfectly fine substitute) room temperature eggs, (bring your eggs to room temperature quickly, by place them in a bowl of warm water for 5 minutes) vanilla extract, and last but not least, your creamy peanut butter.
TIP: Use a light hand while mixing the ingredients, because over-mixing could lead to dry, tough brownies.
How to make your peanut butter swirl: Guys, it’s so easy I promise! Once you have your brownie batter in the pan, simple drop peanut butter by the tablespoon on top. Then, using a knife, gently cut through batter to create a marble pattern. Be careful not to cut through the batter too much, otherwise you will lose the swirl effect.
So what’s the secret to achieving super-moist and super-fudgy brownies every time? Watch them like a hawk while they bake. Now, I don’t mean checking them every 5 minutes, but just keep an eye on them, because it literally only takes as little as 1 minute to overbake and ruin a batch of brownies. — My brownies took exactly 20 minutes at 350º. Just make sure you test them with a toothpick before taking them out of the oven. The brownies will appear very soft when they are done— this is ok and it is exactly what you want.
A toothpick inserted in the middle of your brownies should come out with a few moist crumbs still sticking to it. — If your toothpick comes out with gooey batter stuck to it, the brownies need more bake time. If your toothpick comes out completely clean…well, there’s always ice cream that you can top ’em with to take away the dry texture.
Just do yourself a favor and avoid overbaking these brownies at all costs. Nobody likes a dry brownie. 😉
I don’t know if I’m ever going to be able to go back to regular brownies again. — these are were just way too good….
Bring on the chocolate….♥
You’re gonna want to grab at least two of these brownies as well as a large glass of milk.

These look seriously good! Love PB and chocolate!

Jessi says
I tried this recipe tonight, and I found them inedible. The recipe as described didn’t actually fill a 9×13 pan, so I ended up making another third of it for the proportions to work. I baked them 18 minutes but should have watched more closely, as I think I slightly over baked them. Regardless, the flavor is just not good. The texture was more like a cake than a brownie and it was more savory/bitter than sweet. I literally could not eat more than a bite. I’m not sure if there’s maybe something missing from this recipe, or if I completely missed something, but I can’t eat these at all.
Sarah says
I am so sorry to hear that these brownies didn’t come out good for you, Jessi. I will go back in and re-test the recipe myself to try and see what went wrong when you made them. Sorry again!
alexa lane says
I agree with the commenter about the recipe not fitting a 9×13 pan. The batter Will only be maybe 1/2″ thick if I use the 9×13. I’m going to try it in an 8×8 and see how it goes.
Nataliya says
Yes very small budge for a pan
Jen says
Agreed. I made it work in a 9×13 but they were incredibly thin. I pulled them out at 15 minutes and they were almost over cooked. They tasted ok, but dried out rather quickly due to being so thin. I’ll try them again in a smaller pan or I’ll double the recipe.
Jenna says
I made these tonight and they didn’t turn out very well. 🙁 I followed the recipe, except used AP flour and brown sugar, and the batter was soooo thick! I had to press it into the pan. When I tried to swirl the peanut butter, it just didn’t work, so I spread it over the entire surface. I cooked for exactly 18 minutes. The taste is missing something for sure. It’s bland. How is that possible? I’m super disappointed.
Maria says
I added 3/4c of chocolate chips and they tasted great but the pan size was way too big. They came out SO thin and I had to take them out before 18 minutes to keep it from over baking. Recommend a smallee pan or doubling the recipe.
Sylvia Friessen says
Taste wise I’m sure this recipe is great but it needs baking powder.. I knew it would have to have it but i figured i would go strictly according to recipe.. Bad call.. Add baking powder and it should turn out perfectly
