Homemade keto toffee is so easy but so satisfying. It looks and tastes like the expensive bark in fancy chocolate shops. My buttery walnut sugar free toffee candy has only 5 ingredients plus salt and takes minutes. Even if you've never made candy before you can make this.
99% of the time I make a recipe because there is something I want to eat. I love food. Since I don't have any healthy candy in the house I had to make something yummy (before I cave into the Snickers bars in the grocery check out).
When I first shared this back in 2016, I had my Facebook followers vote on which post I should share immediately and this one won by a landslide. I'm not surprised because it is so good I hid this homemade low carb English toffee recipe in the back of the fridge. And made another dessert for a party so I didn't have to share these.

Ingredients
Sweetener - I use a blend of xylitol, erythritol, and stevia in my recipes. Using either xylitol or erythritol on their own should work as well but I don't test all the possible combinations. Candies can be tricky so I do recommend using the sweetener listed in this.
Cream - Heavy cream or heavy whipping cream are needed for this recipe.
Butter - I use salted butter. The bit of salt in the butter helps balance the sweetness of the candy.
Nuts - Walnuts are the nut I use most often in this recipe but any nut will work.
Chocolate - Choose a sugar-free milk, semisweet, or dark chocolate that melts easily. 85% dark chocolate can also be used.
How to Make Keto Toffee
Toffee is fairly easy to make. If you've ever made any kind of cooked candy before you can make this!
First Step: You cook the sweetener, cream, and butter until it is thickened and golden brown. I add the nuts in the cooking stage so they get toasted right in the caramel. Pour the toffee on a greased foil lined pan.
Expert Tip: Cooking the sugar free toffee to the perfect point can be tricky! I highly recommend watching the video in this post before making this. It is only 1 minute long and very helpful!
Second Step: Cool the keto English toffee until it firms up, then pour on the melted chocolate.
Third Step (optional):If you want chocolate on both sides chill the toffee and then flip it over. Peel off the foil and cover the second side with more melted chocolate.
Fourth Step: Cut into squares and eat your toffee candy!
Storing Homemade Toffee
You can store sugar free toffee at room temperature for a day or two. At room temperature, it will be softer and more caramelly. For it to get crisp like a real English toffee chill it. You can see the difference between my video and photos. In the video, the toffee was room temperature. In these photos, it has been chilled first.
Tips for Making Sugar Free Toffee
I have had readers simplify this by putting the melted sugar free chocolate in a muffin tin with aluminum liners. Chill the chocolate, put the warm toffee on top, chill again, and then top with more chocolate. You get cute little circles that way and don't need to flip the toffee over or cut it. That method can also help with portion control.
Substitutions & Tweaks
This basic combination of cream, butter, and sweetener can be used to make all varieties of keto toffee.
Nuts: Any type of nuts work! We love this with pecans. With pecans, it tastes like cracker toffee aka Christmas crack. Almonds, macadamia nuts, and cashews are all great choices. Make it with peanuts and it tastes like snickers!
Coffee: Mix in a teaspoon of instant coffee when you add the final tablespoon of cream for a mocha flavor.
Seeds: If you can't have nuts pepitas (pumpkin seeds) give a nice crunch in place of the walnuts.
White Chocolate: Now that sugar-free white chocolate chips are more readily available go ahead and try some in place of the dark chocolate!
Cranberries: Add in some sugar-free dried cranberries with the last tablespoon of the heavy cream. They give a nice, tart contrast to the sweetness of the toffee.

Ingredients
- 5 tablespoon butter
- 1 cup chopped walnuts or nuts of your choice
- 5 tablespoon heavy cream
- ½ cup Joy Filled Eats Sweetener (or see alternativesin recipe notes)
- pinch salt
- 7 oz sugar free or very dark chocolate***
Instructions
Line a small baking pan with foil and spray with cooking spray.
Melt butter over low medium until it starts to turn golden. Add nuts and cook for about five minutes until they are slightly toasted. Add 4 tablespoon of the cream and the sweetener. Cook until thickened and golden. This takes about 10 minutes. If it doesn't seem to be thickening you can turn up the heat to medium or medium high but stir constantly. It can burn quickly. Remove immediately from the heat and add the salt and reserved cream. Stir until smooth. Pour onto the foil lined tray and refrigerate until firm to the touch (about half an hour).
Melt the chocolate. I do this in a glass bowl in the microwave stirring every thirty seconds. Add sweetener if needed. Pour half of the chocolate on top of the toffee. Put in the freezer for a few minutes until the chocolate is solid. Flip over the toffee bark and peel off the foil. Put the foil back on the tray and put the toffee on the chocolate side down. Pour the rest of the chocolate on top. Refrigerate or freeze until firm.
The filling stays soft like caramel at room temperature but hardens like a toffee overnight or after refrigerating.

Notes
Chocolate: I used two 3.5 oz Lindt 90% bars and added ⅓ cup sweetener- make sure to use chocolate that you like - you can really taste it in this recipe - if you use very dark or unsweetened chocolate just sweeten it to taste.
Notes on Sweeteners:
Substitutions may not work in this recipe! I do not test all these options. If you want to try another sweetener it is helpful to read through the comments.
I use my ownblend of xylitol, erythritol, and steviain my recipes. This is twice as sweet as sugar. It is comparable toTrim Healthy Mama Gentle SweetandTruvia.
To sub inSwerve or Lakanto Monk Fruit use 1.5 times the amount of sweetener called for.
To sub inPyureorTrim Healthy Mama Super Sweet use half the amount of sweetener called for.
