If you’ve made other keto candies, this toffee recipe is similar to making keto caramel candies, except the mixture is heated to the hard-crack stage for a crunchy candy instead of soft caramels and I use a different sweetener which also affects how quickly the caramel mixture reaches hard crack stage.

You and your holiday guests will love this sweet toffee coated in sugar-free chocolate and sprinkled with pecans and flaked salt for the perfect salty-sweet finish.

How to make keto toffee

  1. Add butter, sweetener and salt to a saucepan and bring to a boil.
  2. Stir and cook until the temperature reads 300 degrees F on a candy thermometer.
  3. Stir in vanilla, and pour it into a baking dish that’s been lined with parchment paper, spreading it out until even.
  4. Let the toffee sit for several minutes. Then sprinkle chocolate chips evenly on top and cover with foil to help melt the chocolate.
  5. Once melted, spread the chocolate evenly over the toffee and top with flaked salt and pecans.
  6. Cover and refrigerate for at least 1-2 hours to set.

Pro Tip: If the chocolate doesn’t melt after covering it with foil, remove the foil and place the dish under the broiler for 30-60 seconds.

Key ingredients & substitutions

  • Butter – I used unsalted butter for this recipe. Salted butter may lead to the recipe tasting too salty and the salt levels in many butters vary from brand to brand.
  • Brown sugar-free sweetener – I prefer the brand Swerve, which bakes just like regular brown sugar with no added calories or sugars.
  • Sugar-free chocolate chips – If needed, you can substitute a sugar-free chocolate bar that’s been crushed into bite-sized pieces.
  • Salt – You’ll need fine-grained sea salt or table salt for the low carb toffee mixture and flaked salt to use as a topping. Flaked salt is coarse and adds the perfect amount of saltiness to each sweet bite of toffee.
  • Pecans – Slivered almonds, crushed walnuts or pumpkin seeds will also work.

What is English toffee?

Toffee is a hard candy made from butter and sugar and covered in chocolate. True English toffee does not include nuts, but in most Americanized versions of the recipe, nuts are added for a fun and flavorful crunch. You’ll often find almonds, peanuts, pecans, or walnuts added to Americanized “English” toffee.

To make keto English toffee, simply remove the nuts from this recipe!

Keto chocolate

What is the hard crack stage in candy making?

Candy making is a true science, as the highest temperature you reach significantly impacts your candy’s texture. Between 300 and 310 degrees Fahrenheit, there is almost no water left in the syrup. This stage is used to make hard candies like toffee, peanut brittle, and lollipop suckers.

If you fail to reach 300 degrees Fahrenheit, the candy will be much softer and more pliable, like saltwater taffy.

This recipe and other keto candies are heated to the hard-crack stage but won’t reach the same level of hardness as traditional toffee since the sweeteners are sugar-free. It will be harder than saltwater taffy but not as hard as true toffee.

Storage information

Store your toffee in an airtight container (a cookie tin works great if given as a gift!) at room temperature for up to a week. It may last longer, but the quality will start to suffer past the one-week point. If refrigerated, it should last 2-3 weeks.

If you’re looking for longer storage, freeze your keto toffee in an airtight container for up to 3 months in an airtight container or freezer bag.

TIP: If your container has multiple layers of toffee, keep them from sticking together by separating the layers with a piece of wax paper.

Keto Toffee: FAQS

Can I substitute granulated white sugar-free sweetener instead of brown sweetener?

You can use white sugar free sweetener, but your toffee won’t have the classic golden brown color that toffee has.

Is toffee the same as caramel?

While toffee and caramel have similar flavors, they’re not the same. Caramel is made of sugar, water and cream and heated to the “firm-ball” stage of candy making, while toffee is made from sugar and butter and is heated hotter to the “hard-crack” candy stage.

What is sugar-free toffee made of?

This keto toffee recipe uses Swerve brown sugar, which is sweetened with the sugar alcohol erythritol, sugar-free chocolate, butter, pecans, and salt.

  1. Absolutely loved these. Candy thermometer is essential. Warning, don’t lick the wooden spoon. I burnt my lip with my enthusiasm.
    I used half the chocolate…one 90% Lindt bar (anout 3 oz.) with about 1/4 c. Splenda and a tbsp of butter. I melted the chocolate ahead of time. Just seemed easier to me.
