Prepare a baking sheet with tin foil and coat with a thin layer of oil or spray with non-stick cooking spray.
Mix the ingredients, except for the baking soda, together in a casserole dish or large microwaveable bowl.
Microwave for 4 minutes on high. Stir and microwave for 3 minutes. Stir and microwave 1 minute.
Quickly stir in baking soda and pour onto tinfoil. This needs to be done quickly before the mixture begins to harden. Using a spatula, spread into a thin even layer.
Let the brittle harden for at least 30 minutes. Once cooled, break into pieces.

Every microwave is different, so you might find that you need to cook your sugar for less or more time. The candy needs to reach 300 degrees F on a candy thermometer before you add the baking soda and pour it out.
If you've cooked it for too long, the candy will begin to turn dark brown and smell burned.
If you don't cook it long enough, it won't be a golden color yet.
You can pour the candy onto a silicon mat to avoid the tin foil.
There's no need to put the candy into the refrigerator or cool it off. It will become brittle at room temperature.
