Easy Low Carb Keto Peanut Butter Fudge

Ahh, peanut butter fudge.

A classic dessert that we all know and love. This Easy Low Carb Keto Peanut Butter Fudge should be no different!

This super sweet dessert is typically made with very simple ingredients including; butter, sugar, milk or cream and some extracts or mix-ins. 

I remember I used to be obsessed with trying new fudge from a local market near us. They always had the most unique flavours.

I was a sucker for chocolate mint fudge back then but sometimes I'd branch out a bit and try some of their more interesting flavours like Butter Pecan, Raspberry Cream, Rocky Road, Lime Cheesecake Fudge..etc. 

Either way, it was all delicious. 

I feel like fudge is also one of those desserts that you can't eat a ton of at once (correct me if I'm wrong, haha) but I find the intense sweetness of it usually means once piece is plenty for an after-dinner treat.

That's why I always liked it. A little went a long way. 

I mean unless your brother, in that case you could probably eat the whole block of fudge in a sitting.

Anyways……

This Easy Keto Peanut Butter fudge recipe is very similar to other classic fudge recipes.

Though we use cream instead of milk and our own low carb sweeteners instead of sugar.

This keto fudge recipe can seem a bit overwhelming with 3 different sweeteners including; allulose, sukrin gold brown sugar sweetener and powdered monkfruit erythritol sweetener, but I promise you don't have to go out and buy them all.

I only include this combination because this is my favourite way to prepare this fudge in terms of flavour and texture. I explain why I add each one in the tips section below.

But you can definitely make this easy low carb fudge recipe using a powdered monkfruit/erythritol sweetener on it's own. Follow the tips below for how to do this or sub one sweetener!

In terms of the butter in this fudge recipe, I used salted butter which I'd recommend for the ease of it but you can also use unsalted and just add about 1/8 tsp salt to your fudge mixture when you add your peanut butter.

I also used heavy cream in this keto peanut butter fudge recipe but if you want to lighten it a bit you can try using half and half or 18% cream for Canadians. 

The peanut butter I used was a smooth, natural, organic brand.

But you can also use crunchy for this recipe if you want some texture to your fudge! Just make sure no matter which you use, that you make sure it's well mixed and the oil isn't separated on top.

Lastly we add a hint of vanilla extract to this recipe to give the peanut butter fudge a better flavour. 

I use pure vanilla extract but artificial also works just fine!

And that's pretty much it! 

This Easy Low Carb Keto Peanut Butter Fudge Recipe isn't complicated and only takes about 10min total to prepare. 

It also only takes about 5min to be devoured by friends and family, haha. So be warned.

Ingredients In Easy Keto Peanut Butter Fudge

• Allulose
• Sukrin Gold Brown Sugar Sweetener
• Powdered Monkfruit/Erythritol Sweetener (see my tips for why I use 3 sweeteners in this recipe and how you can substitute or just use one instead!)
• Natural Peanut Butter – You can use smooth or crunchy. I personally prefer smooth for the classic fudge texture we all know and love!

Tips For Making Low Carb Peanut Butter Fudge

• I use 3 sweeteners in this recipe which I KNOW is a lot. You definitely don't have to go out and buy all three but they do all serve a purpose. Let me explain..
• Allulose helps to provide a “stickiness” to the fudge and acts more like sugar during the boiling part of the recipe to help thicken the mixture. It has a really nice muted sweetness to it and is only about 70% as sweet as sugar.
• Sukrin Gold Brown Sugar Sweetener is used to provide the classic brown sugar flavour in peanut butter fudge, it's not a necessity but a nice bonus. You can also use 1/4 tsp molasses and a regular sweetener in place of this to achieve the same flavour for minimal added carbs in this recipe.
• Powdered Monkfruit/Erythritol Sweetener.. If I could only tell you to buy one of these sweeteners, this would be the one I'd recommend first. Powdered Monkfruit Erythritol Sweetener is just as sweet as sugar (sometimes I find it's actually MORE sweet). It blends seamlessly into no-bake desserts like this one and offers fantastic flavour. Overall, it's my number one sweetener! I use it in this recipe to increase the overall sweetness. You can technically use this for the entire recipe if you don't want to purchase the other 2 sweeteners.
• Make sure to wait until your mixture of butter, sweeteners and cream has for sure started to boil before turning your heat to low. Whisk well and don't leave it unattended for the 2 min required.
• If you have any trouble mixing your fudge mixture with the bowl of sweetener, use beaters to make sure everything gets well incorporated and if for some reason the mixture is not sticking together when you press it in the pan, just add a small amount of warm cream until it does.
