Preheat oven to 350.
In a small pan, melt butter and add in corn syrup and brown sugar. Bring to a small boil while stirring constantly for about 4 - 5 minutes.
Remove pan from heat and add flour, vanilla and cashews.
I lined my cookie sheet with a silpat, but you can use a non-stick parchment paper.
Drop half teaspoonfuls spaced out well apart from each other onto the cookie sheet. I found that I can fit 6 to a cookie sheet.
Bake for approximately 8 - 10 minutes, or until a golden brown color.
Pull out of oven and allow to rest for about a minute on the cookie sheet, and then transfer them over to a cooling wrack.
