Keto Fudge doesn’t need to be complicated
Or have weird ingredients that most people haven’t heard of.
I admit, I am guilty of over-complicating things sometimes. I often think that simple might mean it’s not very good, that it’s plain and uninteresting. It’s my nature to try to add a twist or two, or to try to put an interesting spin on things.
But fudge can be simple, both in ingredients and method, and still be over-the-top delicious. And this keto chocolate peanut butter fudge is case in point.
Four simple ingredients, my friends. Chances are you have 3 of them in your pantry already: heavy cream, sugar-free chocolate chips, and peanut butter. Then all you need are some keto peanut butter cups, like the ones from Lily’s, to press into the top.
But honestly, if you can’t get ahold of those, your fudge will still be amazing. And you could come up with some other fun garnishes instead, like chopped peanuts or a swirl of peanut butter.

Creating a keto fudge recipe
I created this recipe for Lily’s back in the fall, as they wanted a sugar-free fudge recipe to print on recipe cards. I thought it was a fun way to showcase the new peanut butter cups.
Heretofore, all of my keto fudge recipes have used unsweetened chocolate. So it simplified things even further to use sweetened no-sugar-added chocolate. And mixing peanut butter into the cream and chocolate not only gave it great flavor, but the perfect fudge consistency as well.
At the time, I shared the recipe on Instagram only. But I loved it so much and I wanted to share it with more people, so I decided it needed a blog post of its own.
So here it is! The easiest and perhaps most delectable keto fudge you’ll ever make. What are you waiting for?

I made this and followed it exactly and left it overnight. It did not harden. I have to ear it with a spoon. Any idea what could have happened?
What sweetener did you use?
When I search for this recipe, I cannot find it. I found it through my history. Wanted to let you know in case there is an issue on the website.
This is a great recipe. Making for the 3rd this weekend. Eating fresh blueberries with them make them even more amazing.
