Ingredients

- 2 ounces butter
- 3 ounces Swerve sweetener (or your preferred keto-friendly sweetener; erythritol and monk fruit work well)
- 1 teaspoon vanilla extract
How to Make Keto Peanut Brittle
- Prep your pan: Line a baking sheet with parchment paper. This prevents sticking and ensures easy removal. Spread the peanuts evenly on the prepared sheet.
- Create the caramel: Combine the butter, Swerve, and vanilla extract in a small saucepan over medium-high heat. Stir frequently to prevent burning.
- Cook to perfection: Continue cooking and stirring until the mixture reaches a deep brown caramel color. This usually takes about 5-7 minutes. Be careful not to overcook, as this can lead to a bitter taste.
- Combine and cool: Carefully pour the hot caramel over the peanuts, ensuring they are evenly coated. Let the brittle cool completely at room temperature. This will take approximately 30-50 minutes.
- Break and enjoy: Once the brittle is completely cool and hardened, break it into bite-sized pieces.
Tips & Tricks
- Use a candy thermometer: For perfectly cooked caramel every time, use a candy thermometer and cook the mixture until it reaches 300°F (150°C).
- Don’t over-stir: Stirring too much can cause the sugar to crystallize, resulting in a grainy texture.
- Control the thickness: Spread the caramel mixture thinly for thinner brittle and more thickly for thicker pieces.
- Add a twist: Get creative with flavors! Add a pinch of sea salt, sugar-free chocolate chips, or a dash of cinnamon to the caramel before pouring it over the nuts.
How To Store Peanut Brittle
To maintain its crunch, store peanut brittle in an airtight container at room temperature for up to a week. Avoid storing it in the refrigerator.
