Eating peanut brittle has been a tradition in our family for as long as we can remember. It was my grandmother's favorite candy. It’s just something we grew up eating, and I didn’t want to give that up just because I eat low carb. There is always a solution to your favorite recipes; you just have to play around with the ingredients until you get it perfect. I can tell you that this keto peanut brittle is about to change the way you think about making homemade candy.

You won’t believe how incredible this Caraway Cookware is! Not only is it non-toxic and eco-friendly, but it’s also non-stick too. When I say non-stick, I REALLY mean it!

If you have made a cooked caramel before, or any candy such as my Keto Toffee, you know that it can be hard to clean from the pan. I was amazed by how easy the pan was to clean after making this keto peanut brittle. Normally, it’s so hard to clean, and I consider tossing the pan, but not this time.

In addition to having a frying pan, saucepan, saute pan, and dutch oven Caraway Cookware also has a fantastic magnetic pan rack and canvas lid holder. They are game changes when it comes to getting your kitchen organized.

I am super excited about all the different colors you can get from the Caraway Cookware. I went with sage, and it’s seriously so gorgeous. You can also choose Cream, Gray, Perracotta (a cross between Terracotta and Pink), Navy, or their limited edition Marigold. Having cookware that actually does its job and happens to look cute at the same time is a win all around if you ask me.

So, if you are looking for some fantastic cookware, I highly recommend checking them out. I only recommend products I love and this is my favorite cookware. With a family of 8, we are hard on our cookware and Caraway lives up to us!

What You’ll Need

You won’t believe that there are only 4 ingredients needed to make a batch of keto brittle. Let’s take a look.

• Butter - I use salted butter in this recipe.
• Heavy Cream - This can be called heavy cream or heavy whipping cream depending on the brand.
• Roasted Salted Peanuts - or nuts of your choice. If they are large pieces chop them first.
• Trim Healthy Mama Gentle Sweet or my sweetener made from a combination of xylitol, erythritol, and stevia.

How To Make Keto Peanut Brittle

Step One: Place parchment paper on a cookie sheet and set it aside.

Step Two: Add the butter, 3 tablespoons of heavy cream, and the sweetener to the pan.

Cook over medium-low until it’s thickened up and turns deep golden brown. This step takes around 10 minutes. Stir it frequently. I don't bother with a candy thermometer because you can tell just by the color and fragrance when this is done.

Expert Tip: If you notice that it doesn’t seem to be thickening up, you can go ahead and turn up the heat to medium or medium-high. If you turn up the heat you must stir it continually. It goes from perfect to burned in seconds.

Remove the mixture from the heat and add in the rest of the heavy cream. It will bubble up. Stir until it’s smooth.

Then mix in the peanuts or nuts of your choice. Carefully pour the brittle onto the baking sheet and put it in the fridge overnight. Break into pieces, serve, and enjoy!

Tips For Making Peanut Brittle

• Try to avoid making the peanut brittle when it’s super humid. This can greatly affect the peanut brittle and not turn out as well. So, choose a dry day and you should be okay.
• Using a high-quality non-stick pan, like Caraway, is a game-changer and will save you a HUGE headache when it’s time for cleanup.
• You can use your hands or even a wooden spoon to break apart the keto peanut brittle once it’s cooled.

How Do You Store Peanut Brittle?

Peanut brittle should always be kept in the fridge, or it will become too soft. Make sure it’s in a container that is sealed tight, and it will last 3-4 weeks. This makes a great gift for people for the holidays, especially since you can make it in advance.

Additionally, you can store the keto peanut brittle in the freezer too. It should be wrapped tight and in an airtight plastic or glass container. It will last up to 6 months in the freezer, so you can always have some on hand when a craving strikes.

Can I Use a Variety of Nuts?

Yep! We love to eat ours with just peanuts most of the time, but you can certainly add a mixture if you want. Hazelnuts, walnuts, pecans, and almonds are a lovely combination that you may enjoy. I love my Salted Chocolate Almond Brittle Bark as a variation on this.

Can I Make this into a Soft Caramel?

Yes, this can be a softer chewier candy if you add an extra tablespoon of cream and leave it at room temperature. It's chilling that hardens the candy into a brittle texture. At room temperature with the peanuts this almost tastes like a gluten free Snickers bar! You can cover it in melted sugar-free chocolate to really get to that flavor.
