Peanuts (1 cup)
Peanuts are the star of this recipe, providing a satisfying crunch and nutty flavor. They are a great source of protein and healthy fats, making them perfect for a keto diet.

Erythritol is a sugar substitute that allows you to enjoy sweetness without the calories or carbs of traditional sugar. It has a similar taste profile, making it ideal for baking and candy-making.
Unsalted Butter (1/4 cup)
Unsalted butter adds richness and creaminess to the brittle, enhancing the overall flavor. It also helps bind the ingredients together, creating that classic brittle texture.
Vanilla Extract (1/2 teaspoon)
A splash of vanilla extract brings warmth and depth to the flavor profile. It complements the nuttiness of the peanuts, rounding out the sweetness perfectly.
Baking Soda (1/2 teaspoon)
Baking soda is essential for creating the light, crispy texture of the brittle. It helps aerate the mixture, ensuring that each bite is crunchy and satisfying.

Variations
While the classic Sugar Free Keto Peanut Brittle is a delightful treat on its own, there are several variations you can explore to suit your taste preferences or dietary needs.
Chocolate-Dipped Peanut Brittle
For those who love the combination of chocolate and peanuts, consider dipping your cooled brittle in sugar-free dark chocolate. Melt the chocolate and drizzle or fully coat the pieces for an indulgent twist that adds richness and depth to the flavor.
Nut Variations
Feel free to mix things up by incorporating different nuts into your brittle. Almonds, pecans, or walnuts can replace or complement the peanuts, providing a unique flavor profile. This is a great way to customize the recipe to your liking while still keeping it keto-friendly.
Spiced Peanut Brittle
If you enjoy a little extra warmth in your sweets, try adding spices such as cinnamon or cayenne pepper to the mixture. A pinch of sea salt can also enhance the sweetness and give your brittle a delightful contrast. This variation can add a surprising kick to the traditional recipe.
Coconut Peanut Brittle
For a tropical twist, consider adding unsweetened shredded coconut to your peanut mixture before pouring it onto the baking sheet. This not only adds flavor but also a chewy texture that complements the crunch of the peanuts nicely.
Experimenting with these variations allows you to enjoy the same great taste of peanut brittle while keeping things exciting. No matter how you choose to customize your Sugar Free Keto Peanut Brittle, you’re sure to create a delicious treat that satisfies your sweet cravings!

Cooking Tips and Notes
Creating the perfect Sugar Free Keto Peanut Brittle can be a delightful experience, especially when you follow these helpful tips and notes.
Use Quality Ingredients
Using high-quality peanuts can significantly enhance the flavor of your brittle. Opt for raw or roasted unsalted peanuts, as they provide the best texture and taste. Fresh ingredients, like erythritol and butter, will also improve the overall quality of your candy.
Monitor Cooking Temperature
When melting the erythritol and butter together, keep the heat at medium. Too high of a temperature can cause the erythritol to caramelize too quickly, which may affect the texture of your brittle. Stir continuously to ensure even melting and to prevent burning.
Cooling Time is Key
After spreading the mixture onto the baking sheet, allow it to cool completely before breaking it into pieces. This resting time ensures that the brittle firms up properly, making it easier to handle and enhancing its crunchy texture. Patience pays off here!
Storage Tips
To maintain the freshness of your peanut brittle, store it in an airtight container at room temperature. Avoid refrigerating it, as this can introduce moisture and make the brittle chewy. If you plan to make a larger batch, consider wrapping individual pieces to keep them fresh longer.
With these cooking tips and notes, you’re well on your way to crafting a delicious and satisfying keto treat that everyone will love!
