This is a quick low carb and Keto peanut brittle recipe that you can make in about 10 minutes.
Today I’m going to share a recipe for quick Keto Peanut Brittle that you make in 10 minutes.
But first I want to celebrate a very special anniversary. Eighteen years ago, SNL aired the “More Cow Bell” skit. And the world hasn’t been the same since.
I can’t believe it’s been 18 years.
It seems like only yesterday when I first watched this classic SNL sketch about song that just needed a little more cow bell. It has been called the first meme of the twenty first century and they may be right. So if somehow, you’ve never seen the "More Cowbell" sketch, then now is the time. Because, as Christopher Walken says, “I’ve got a fever and the only prescription is more cow bell.”
I’ll tell what else I have a fever for: Keto Peanut Brittle, that's what.
I just had to move it away from my desk because I’ve eaten way too much of it. It is dangerously delicious. But this sugar free peanut candy only has 1g net carb per serving, so you can afford to splurge a little bit.
Go ahead, live a little.
But I do have a warning that goes before this Keto Peanut Brittle recipe.
It's candy, so it's very tricky to get just right. And to further complicate things, you are making a caramel with erythritol, which doesn't behave the same way that good old sugar does. The color of the brittle mixture is everything. You want to stop cooking this mixture when it's a deep dark brown color. If it's a light or medium caramel color, then it will be grainy and crumbly. But if you cook it too long, it will be burnt.
You are walking a fine line, my friends.
But enough brittle talk, now I think I need just a little more cow bell.
📋 Recipe
Quick Low Carb Keto Peanut Brittle
This is a quick low carb peanut brittle recipe that you can make in about 10 minutes.
- Prep Time: 5
- Cook Time: 5
- Total Time: 10 minutes
- Yield: 8 1x
- Category: Dessert
- Cuisine: American
- Diet: Diabetic
Ingredients
- 1 cup salted dry roasted peanuts
- ¼ cup butter
- ½ cup Swerve Granular
- 2 teaspoons vanilla extract (alcohol-free if possible)
Instructions
Step 1. Line a 9 x 13-inch casserole dish or large rimmed cookie sheet with parchment paper. Use a medium-sized, light-colored, or metal saucepan, if you have one because they will make it easier to gauge the color of the brittle mixture. Make space in the fridge for the casserole dish or cookie sheet.
Step 2. Add butter, sweetener, and vanilla to a medium-sized saucepan and cook over medium heat until fully dissolved and no longer grainy, stirring constantly.
Step 3. Bring to a low simmer. Lower the heat to low and simmer for 1-3 minutes, stirring constantly, until the mixture reaches a deep brown color. It’s very easy to burn the caramel, so stop as soon as it starts to become brown. It will happen quickly. But don’t take it off the heat if it is still tan in color, because that will make it crumbly and grainy.
Step 4. Remove from heat, mix in peanuts and pour into the parchment-covered pan. Smooth out the nuts so they are evenly distributed. Make sure that the brittle mixture is touching all the peanuts to hold the brittle together.
Step 5. Chill in the refrigerator until set, about 1 hour.
Step 6. Chop roughly.

I followed the instructions with the listed ingredients. I'm so disappointed because my husband loves peanut brittle.
Wish I could attach the pic. It's very pale colored, grainy and crumbly. Any idea what might have happened?
EmilyKrill says
Oh no! I am so sorry that it didn't turn out. I've made it several times and it's always turned out fine for me. It sounds like you didn't cook the brittle mixture long enough. You need to cook it until it's dark brown, not light caramel.

We had a similar experience with it being too light and and grainy. Not enough heat under the pan, so we probably never got the mixture up to 300 degrees. One needs to set aside the fear of burning the sugar to get it to the right place. We may still be stopping short as we still don't see the "hard crack" transformation in the pan, though the resulting brittle is crunchy.
We melt the butter and sugar mixture at medium-high over a gas burner. Takes about 10 minutes to get it to a rich brown, almost coffee colored. We toss the Vanilla in at ~300 degrees, so it essentially boils the alcohol off immediately, but that helps the mixture bubble. We also toss in about a half teaspoon of salt and a quarter teaspoon of baking soda, which again helps to make the mixture frothy, though by the time it cools, there is no evidence of that.
Crunchy and delicious, though actually a bit too sweet, so good with unsweetened coffee or tea.

So....1 carb per serving ( who am I kidding?? I'm eating ALL of it the same day.)
Worth it!!!!

Alice Coaxum says
Looks yummy! I want to try this maybe with a blend of erythritol and Stevia.
EmilyKrill says
That sounds great. I'm sorry, I don't know how the ratios would go though. It'll just take some taste testing to get the sweetness right.
erin says
does this recipe work with splenda?
EmilyKrill says
I’m sorry, but I don’t know the answer to that. I’ve never tried making candy with Splenda.
