Fudgy Peanut Butter Bars

For my sister.

I’m baking you a treat.

Because you are so pretty,

And you always make me laugh.

Because we shared a clothes in high school,

And you painted my toes when I was 13 months pregnant. 😉

Because I love you sister that made you a yummy treat…

Happy Birthday my beautiful, wise yet-still-older-sister Julie!!!

I love you! 🙂

All right.Let me break it down for you on these bars. THESE. ARE. YUM.


First this recipe came to me as a peanut butter bar. The crust is like fudge with a few scattered peanuts for some texture and deliciousness.

Then I thought about ganache… who doesn’t dream of melted chocolate? So I poured over the top! {In my opinion} this dessert is not overly sweet and totally the perfect marriage of peanut butter and chocolate.

I love these bars. Speaking of marriage…

Here we have the ingredients… pretty simple.

Grease and line an 8×8 pan with parchment paper.

Place the butter, peanut butter, light brown sugar and granulated sugar in a large bowl of your mixer.

Add one teaspoon of vanilla… the real stuff.

Mix until blended and is light and creamy.

Add the salt, baking soda and powder, half of the flour. Mix and then add the rest of the flour.

Keep mixing until all the flour is incorporated, scraping down the sides as well.

Dump the dough into the prepared pan.

With a spatula, spread it evenly and press with fingers to flatten a little. Bake the dough in a preheated 350 degrees for 20-25 minutes or until the top is golden. Since this dough is egg free, if you insert a tester and it comes back with a little dough on it, it’s okay… remember it’s suppose to be “fudgy”!

Let it cool completely in pan on a wire rack.

Once the bars are cooled it will be time to make the ganache. To make this, you need semi-sweet chocolate and heavy cream.

Chop the chocolate into small pieces.

And place it into a medium sized bowl.

Next pour the cream into a small sauce pan, bring just to a simmer and then quickly pull it off the heat and pour over chopped chocolate.

Let it sit so the chocolate has a chance to soften up.

Then stir. Slowly. You don’t want to get any air into it.

Let the ganache hang out until it’s thick but pourable.

Pour into the center of the bars.

Tilt the pan to coat evenly. Chill for about an hour.


And enjoy! These bars are so delicious. My sister was so kind to let me take a couple of her birthday bars for my girlees and me to try. I don’t know if I could be so generous! 😉

Im in love with the texture and with their fudgy-ness. I can’t wait to make these for my husband… he will love love LOVE them and you will too!

    I'd bookmarked this when you first posted for two reasons…1) they looked fantastic, and 2) I have a sister who is crazy for peanut butter and chocolate, too. I meant to wait until she came to visit, but I couldn't hold out. So glad I caved! Super easy and crazy good. Thank you!!! And thanks for your wonderful blog…

    I'm making these right now! I was craving some type of peanut butter treat, but needed something that I had all the ingredients. These are great to make up quickly! Already had the ganache frozen.

    I made these today and they are excellent. It's probably the best peanut butter thing I have ever had. Ever. I did use and 8×8 and it cooked over a bit, I might try a 9×9 tomorrow. I also cooked it for 35 minutes as it seemed to jiggle a bit after 25min. We ate most of it without the chocolate and it was wicked. The texture of this will impress everyone!

    I made these peanut butter bars this past week and they were fabulous! I wasn’t sure what to expect the texture to be, but they turned out to be soft and a bit crumbly, which was perfect with the fudgy chocolate ganache on top. I also used only smooth peanut butter and not the crunchy so that may have contributed to my texture difference as well. These were very quick and easy to make and if you have a peanut butter lover in the house then you must make these pronto! My husband LOVES peanut butter/chocolate and went nuts for these.

    Thanks for a great recipe!

      Hi there Ashley! Yes they are suppose to be on the soft/crumbly side. Since there isn’t eggs in the recipe, baking is just to set the dough and brown/crisp it up a tad. They are perfectly fine a little under-baked {which I prefer!}. The smooth peanut butter shouldn’t have been an issue. But I’m stoked to hear you like the bars! I know I do! In fact… I’m craving them now! 🙂

    I forgot to mention in my previous post that I ended up baking these for about 30-35 minutes…..at 25 minutes I put a toothpick in and they were still not cooked all the way through.

    I can’t believe I’ve never posted a comment here. These have easily become one of my family and friends’ favorite desserts. I am an avid baker and to rank this in the top of our favorite desserts is an honor!! These bars are SO easy to make, and the taste and texture is amazing. Don’t be fooled – they are not just another PB and chocolate bar. I’ve made the gananche with both semi-sweet and dark chocolate, but we actually prefer the semi-sweet in this recipe. Be careful not to overbake. Also, I always 1.5x the recipe and bake in a 9×13 pan because a smaller pan just wouldn’t be enough of this heavenly deliciousness. Worth every calorie, I promise!
