Ingredients

• 1 cup Raw peanuts
• 1 cup Erythritol
• 2 tablespoons Butter
• 0.25 cup Water
• 1 teaspoon Vanilla extract
• 0.5 teaspoon Salt
• 0.5 teaspoon Baking soda

Directions

Step 1

Prepare a baking sheet by lining it with a silicone mat or parchment paper. Set aside.

Step 2

In a medium saucepan, combine the erythritol, butter, and water over medium heat. Stir continuously until the erythritol has dissolved and the mixture begins to simmer.

Step 3

Once simmering, attach a candy thermometer to the side of the saucepan without touching the bottom and continue to cook. Stir occasionally to prevent burning until the mixture reaches 300°F (hard crack stage), which should take about 10-15 minutes.

Step 4

Remove the saucepan from the heat and quickly stir in the vanilla extract and salt.

Step 5

Add the peanuts to the mixture, stirring to ensure they are evenly coated.

Step 6

Sprinkle the baking soda over the peanut mixture and stir quickly. The mixture will become frothy as the baking soda reacts.

Step 7

Immediately pour the mixture onto the prepared baking sheet, spreading it out evenly with a spatula.

Step 8

Allow the brittle to cool completely at room temperature. It should harden as it cools.

Step 9

Once cool, break the peanut brittle into pieces and store it in an airtight container for up to two weeks.
