Tips
These are large cookies (and you deserve it!), should you choose to make them smaller, reduce baking time so the edges don't burn.
Use real butter, not margarine. Margarine doesn't brown and caramelize.
Tips to Make them Thin and Crispy
Do not chill the dough. Mix and bake immediately.
Brown the butter. Melted butter helps them spread and caramelize.
Note the minimal amount of flour.
Do not use aluminum foil or grease your cookie sheet.
Use a spatula to remove them from the sheet after they cool for 5 minutes and allow them to cool on a wire rack to continue to crisp.
To Store
Room Temperature - Cool cookies before storing in a glass airtight container. Store with wax paper up to 2 weeks.
Refrigerate - Cool cookies before storing in a glass airtight container. Store with wax paper up to 2 weeks. This method is great for keeping them crisp, especially in humid environments.
Freeze - Freeze in an airtight container to keep them from crumbling, with wax paper, for up to 3 months. Bring to room temperature to thaw.
