Step 1

In a small bowl, combine baking soda, cinnamon, and nutmeg. Set aside.

Step 2

Spray a baking sheet generously with cooking spray, then set aside.

Step 3

In a large microwave-safe bowl, add granulated sugar and light corn syrup. Use a spatula to stir until combined. The mixture will be very sticky and difficult to stir near the end; this is okay.

Step 4

Microwave sugar syrup mixture on HIGH for 4 minutes, then stir. Return bowl to microwave and heat for another 3 to 5 minutes or until mixture turns a light golden color. Be careful not to overheat; a dark brown hue means the sugar has burned.

Step 5

Remove bowl from microwave and quickly begin to add the following ingredients: vanilla, butter, the prepared spices from step 1, and the peanuts. Stir the mixture so that all the ingredients are combined. The mixture will lighten and may rise or appear "fluffy.”

Step 6

Spray rim of the bowl with more cooking spray, then pour the brittle mixture on the prepared baking sheet. Working quickly, use a spatula or a spoon to smooth the peanut brittle out in a layer roughly the same thickness as the peanuts.

Step 7

Let peanut brittle cool and harden for at least 1 hour. Once cooled and firm, use your hands to break the brittle into sizes of your choice (usually 2x2 inch in size)

Step 8

Because working with heated sugar can be tricky and temperamental, it is best to make this recipe only for the listed portion. Doubling this recipe is not recommended.
