Keto Fudge

When it comes to keto candy recipes, my favorite recipes to make are bounty bars, crunch bars, and this 2 ingredient keto fudge.

It’s no secret that I have an insatiable sweet tooth. You will always find some form of dessert or sweets in my kitchen or pantry. Like clockwork, every week I churn out a fresh batch of cookies or brownies, and sometimes if I’m in a homely mood, some low carb banana bread. Recently though, I’ve thought to give my oven a break and I’ve been loving my no bake desserts and candy. When my sweet tooth is calling and I want to put little effort into making something, I whip up some keto chocolate fudge.

I’ve been meaning to share a keto fudge recipe for quite some time now. If you are ever wanting to satisfy your sweet tooth INSTANTLY, this is your answer. It’s a fabulous keto chocolate dessert that literally takes 5 minutes to make. Also, you DON’T need any cocoa powder to whip it up. 

No butter, no oil, and no sugar are needed, but you’d never tell. The texture is smooth, creamy, and melts in your mouth. It’s sweet and full of chocolate flavor! 

Seriously, if you want an instant chocolate fix that is simple to make but feels incredibly fancy, this 2 ingredient fudge is your answer.

How do you make low carb fudge? 

The Ingredients

  • Peanut butter– Smooth and sugar free peanut butter. Your peanut butter should be drippy in texture, or it won’t whisk nicely into the melted chocolate. 
  • Keto chocolate OR chocolate chips- Either sugar free chocolate chips or a chopped keto chocolate bar. 

The Instructions

In a microwave safe bowl or small saucepan, combine your peanut butter with chocolate. Heat or microwave the mixture until the chocolate has melted. Whisk together, until smooth and combined. 

Now, transfer your fudge mixture into a lined 8 x 8-inch square pan or loaf pan. Pour your fudge mixture into it and refrigerate it for at least 2 hours, to firm up. Once it is firm, slice it up into squares.

Flavor variations

This fudge is a very foolproof recipe, and comes with some substitution and flavor variation ideas! 

  • Substitute the peanut butter– Instead of using peanut butter, use almond butter or cashew butter. Again, be sure that is has a smooth and drippy texture. 
  • Make it nut free– Replace the peanut butter with either sunflower seed butter or smooth tahini. 
  • Add some mix-ins– Add your favorite chopped nuts, seeds, or coconut into the fudge. 

Storing and freezing tips

  • To store: As fudge is fragile, it should always be stored in the refrigerator, in a sealed container. The fudge will keep well for up to 1 month. 
  • To freeze: Place the fudge in a shallow container and store it in the freezer for up to 6 months.

    Well to start with Thank you for this recipe! I made it tonight but after whipping it i gave it a taste and found it wasn’t sweet enough for me so I added in some splenda/generic and it did the trick. I then added chopped pecans to the top and it is resting in the fridge now. I will cut it up here in a minute and place in a container to keep it fresh but I wanted you to know just how much I appreciate all your recipes and look forward to trying them out. I love how easy and simple they are and just 2 ingredients is wonderful!! Thanks again.

  2. Do you recommend natural peanut butter (just peanuts as the ingredient, no sugar or oil) or can a regular Jif or Skippy brand peanut butter be used? Thanks!

  3. Thank you for your wonderful recipes and pictures of the recipes I would love to make the chocolate and peanut butter keto fudge but how much peanut butter and how much chocolate chips can you please put the amounts to be used thank you so much

  4. Is it possible to us the 100% chocolate or close to and the peanut butter without the sweetness? They all leave a horrible lie lingering taste to me.
