Peanut Butter Fudge Brownies

Peanut Butter Fudge Brownies are pure decadence! Fudge-like brownies topped with a peanut butter layer and a chocolate ganache.

Peanut Butter Fudge Brownies
You know those desserts that are so rich you “only need a little piece”?  Yeah, me neither.  Seriously, I can never relate when someone says something like “Oh cheesecake is so good but I can only eat a couple of bites” or “I just need one little sliver of that pecan pie.”  Nope, not me.  

Ingredients in Peanut Butter Fudge Brownies

Unsalted Butter

Semisweet Chocolate – I recommend using bars of chocolate, opposed to chocolate chips. 

Granulated Sugar

Vanilla Extract


All-Purpose Flour

Salted Peanuts

Peanut Butter

Powdered Sugar


How to Make Peanut Butter Fudge Brownies

To start, you’ll make the brownies.  Combine the butter, semisweet chocolate, and unsweetened chocolate in a saucepan and heat until it’s all melted together.  To this, you’ll add the sugar, vanilla, salt, and eggs and whisk until well combined.  After this, you’ll simply stir in the flour followed by the salted peanuts, and then spread the brownie batter in a greased 9×13″ baking dish and bake for about 30 minutes.

Once the brownies are made and cooled, you can make the peanut butter frosting.  The frosting is made by beating together peanut butter, butter, powdered sugar, vanilla, milk, and salt.  Pretty easy!

Lastly, you make the chocolate ganache. To do this, you simply melt more chocolate and butter together, and spread it on top of the peanut butter frosting layer.  I like to top the brownies off with more salted peanuts for looks and for the extra crunch.

There was something about the sweet chocolate and the salty peanuts that kept me going back for more.  I’ve said it before and I’ll say it again: you just can’t go wrong with peanut butter and chocolate.

  1. HAHA! I laughed when I read your first few sentences. I totally agree! Nothing is too rich or sweet for me. I actually get mad when people are like ‘oh I could only have a little bit.’ Meanwhile, I’ve got my shovel out and enjoying a huge hunk.

    These look devilishly good..
    Where’s my shovel?

    I’m not that kind of person that is satisfied with a little piece of a decadent dessert either. I allways want more!

  4. Oh my – peanut butter and chocolate is my absolute favorite combination. AND – I am like you – I just don’t hold back. I am known to take a little sliver, than another … and another – and before you know it….. you guessed it!
