Heat oven to 350 degrees. Mix all ingredients in a bowl until well combined. Line baking sheets with parchment paper or no-stick aluminum foil. Drop batter 3/4-tsp. at a time on baking sheet, leaving plenty of space between each. Cookies will spread to 4 or 5 inches in diameter when baked.

Bake 10 to 12 minutes, until thin and golden. Check early to make sure they don't overbrown. Line a wire rack with wax paper. Carefully remove cookies from baking sheet. They will be sticky, and a thin, metal spatula works best. Gently transfer to wax paper on wire rack and let cool.
