Microwave Cashew Brittle

Lightly butter a baking sheet with 1 teaspoon butter.

Mix cashews, sugar, and corn syrup in a medium microwave-safe bowl. Microwave on high for 4 minutes. Remove, stir, and microwave for another 3 minutes. Remove and add 1 tablespoon butter, vanilla extract, and butter flavoring; stir to combine. Microwave for 2 minutes.

Remove from the microwave and add baking soda; stir and fold until mixture is fluffy. Work quickly and spread mixture evenly on the prepared baking sheet. Let it sit until completely cooled. Break into pieces and keep in a airtight bag or container.
