Peanut Brittle for One

Measure corn syrup into a 2-cup liquid measure, scraping the measuring spoon clean after measuring the first tablespoon and before measuring the second one.

In a microwave oven, cook for 1 minute and 15 seconds (700-watt oven) or for 52 seconds (1000-watt oven) at 100% power.

Cook at 100% power for 1 minute and 15 seconds (700-watt oven) or for 52 seconds (1000-watt oven).

Add butter, vanilla and baking soda. Stir quickly and thoroughly.

Spread brittle on the buttered metal cookie sheet. Do not use a glass baking dish. Even tempered glass (like Pyrex) may break as the candy hardens.

Break into pieces. Store in an air-tight jar.
