I have been making these easy Keto Twix Bars for well over a decade now. And every time I do, I am reminded of why I love them so much. They have everything I enjoy about the classic candy bar, minus the sugar rush.
Once I developed my keto caramel sauce recipe, recreating Twix bars in a healthier, low carb way was top of my list. Who can resist that combination of tender-crisp shortbread topped with gooey caramel and coated in chocolate? It’s heavenly stuff!
If you love caramel, be sure to give try Keto Salted Caramel Cheesecake Bars or Keto Pecan Turtles next!
I also love these bars because they are so simple to make. There’s no need to dip each bar entirely in chocolate. It’s time-consuming, higher in carbs, and doesn’t make much difference to the flavor. Instead, you simply make a pan of caramel coated shortbread, and spread the chocolate over the top. Then cut into slices.
I made them again recently and my daughter took some to a friend’s house. Apparently the whole family loved them and couldn’t believe they were sugar-free!
Reader’s Thoughts
“Thank you, thank you, thank you! These are amazingly delicious! I made these keto Twix bars and they turned out perfectly as written.” — Jean F.
Why You Will Love These Keto Twix
- Simple preparation: No fussy process here, and no messy dipping in chocolate. It’s quick, easy, and delicious!
- Crispy shortbread: I love this simple almond flour shortbread crust and use it frequently in my dessert recipes.
- Gooey caramel: A keto caramel sauce that stays soft and gooey!
- Customizable: Use milk chocolate or dark chocolate for the topping – the choice is yours.
- Make ahead recipe: You can prep these bars ahead of time and refrigerate or freeze.
- Low carb and gluten-free: No grains or sugars make these treats perfect for the keto diet.
Ingredient Notes
- Almond flour: Almond flour makes the best keto shortbread crust, but if you need to be nut-free, you can try sunflower seed flour instead.
- Sweetener: I recommend an erythritol based sweetener for the crust. The filling takes a brown sugar replacement and some allulose.
- Heavy cream: To make the gooey caramel sauce.
- Xanthan gum: This keto thickener helps in the crust, to make it less crumbly. It also helps thicken the caramel sauce. Glucomannan might also work.
- Sugar-free chocolate: I like to use dark chocolate, but milk chocolate works well too. Both ChocZero and Lily’s are good in this recipe.
- Kitchen staples: Butter, vanilla, and salt.
How to Make Keto Twix Bars
- Prepare the crust: Combine the almond flour, sweetener, xanthan gum, salt, and melted butter. Press the mixture firmly into the bottom of baking pan lined with parchment paper and bake until golden brown. Remove and let cool completely.
- Prepare the caramel: Combine the sweeteners and butter and bring to a boil. Remove from heat and add the cream and vanilla extract. Sprinkle the surface with xanthan gum and whisk vigorously to combine, then whisk in the salt. Bring back to a boil for another 2 to 3 minutes.
- Add the filling: Let the caramel cool until thickened but still pourable. Pour over the crust and spread to the edges.
- Freeze: Place the pan in the freezer for 1 to 2 hours, to set the filling.
- Melt the chocolate. Set up a double boiler and melt the chocolate until smooth. Pour over the bars and spread to the edges.
- Chill the bars: Refrigerate 30 minutes to set the chocolate before cutting into bars.
Tips for Success
Be sure to line your pan with parchment paper, so that you can lift the bars out in one piece and cut them to your liking. I cut mine in half, then cut each half into 1-inch wide bars.
Boiling the caramel in two stages helps it thicken up better. In the second stage, you know it’s ready when the bubbles move more slowly to the surface. Don’t pour the caramel sauce right away or it will soften the crust. Let it cool for 10 minutes first.
Set up a double boiler for melting the chocolate so that it doesn’t seize or clump. Place a heatproof bowl over a pan of gently simmering water. Don’t allow the bottom of the bowl to touch the water. Then stir frequently until the chocolate is melted and smooth.
Use a good sharp knife for slicing through the bars evenly. If the bars have just come out of the fridge, it’s a good idea to heat up the knife first to make clean slices. I like to hold my knife over the open flame of my gas stove.
Sweetener Options: It’s important to use an erythritol based sweetener, with no allulose in it, if you want a crisp shortbread crust. However, the caramel sauce does require some allulose or xylitol for a gooey consistency.

Crust
- Preheat the oven to 325ºF and line a 9×9 inch pan with parchment paper, allowing some overhang for easy removal.

I made these yesterday. Just wondering about the amount of coconut sugar– 2 tablespoons seemed like a lot (24 carbs worth!) I could do the math, but since I’m lazy I thought I’d just ask– is it supposed to be 2 teaspoons by chance?
No, it’s 2 tbsp. Yes, I know it’s carby but it really helps the consistency of the caramel. You can go all erythritol if you like but it may harden more after cooling. Or you can do all erythritol with 2 teaspoons (not TBSP this time!) of molasses to get the right colour, but it will still harden up a bit after cooling. Coconut sugar seems to hold moisture better and keeps the erythritol from recrystallizing.
Milk chocolate, caramel, and low carb? Sounds wonderful!!! Milk chocolate is my favorite, and the only thing I like as much as chocolate is caramel. Thanks for another great recipe.
My favorite chocolate is Hershey’s special dark. Mm. But I’ve had Lilys and it is *good*! I’m assuming regular sugar is a fine swap for the coconut sugar. If I wanted to make this completely sugar free, could I use more Swerve or maybe a little Stevia?
Yes, you can use more Swerve, but your caramel will be lighter and may harden after cooling.
dark chocolate covered almonds 🙂
My favorite chocolate is dark chocolate with sea salt
I really love dark chocolate especially with almonds or cherries mixed in 🙂
I used to be a huge Milk Chocolate fan, but I found over the past few years that I prefer dark chocolate now and that love has grown since going low carb.
I love your site! Thanks for sharing all your fabulous creations!!!
Oh my goodness. I agree with you, I definitely prefer dark chocolate but these look pretty crazy good. Can’t wait to make them!
I love all your treats Carolyn. I can’t wait to make these for a party this weekend. Can you let me know how you would recommend storing them? Can they be refrigerated frozen or will that wreck the caramel.
Mine were fine on the counter for 3 days. That’s as long as they lasted…
Milk chocolate is my favorite!!!
I love milk chocolate!
These sound amazing! My husband is a Twix “freak”….and he’s been without them since August 24, 2013 – he’s also without 52 pounds. Betting this recipe will help with the “withdrawls”…
Love dark chocolate the best, but milk chocolate will do just fine!
ok what else can I use to sweeten these twix candy ? othere than that sweetener ?
You can try other low carb sweeteners but I can’t guarantee how they will turn out. Swerve caramelizes so it’s the best choice for caramel sauce.
My favorite kind of chocolate is, well, almost any kind, actually! I’ve been doing dark chocolate lately, ’cause it’s not as sweet. We buy that 1# bar from Trader Joes & it lasts a couple days… 😉
This recipe looks sooooooo awesome! Thanks for posting it…
These look so yummy, I’m excited to make them!
