For a slightly different texture, increase flour and decrease oats to one and a half cups each. Increase baking soda to one teaspoon.
For a chewier cookie, decrease chips to half a cup and add half a cup dried cranberries.
For a simchah: Drizzle with melted chips (chocolate, white, or caramel). Put chips in a snack-size ziplock bag, dip in boiling water until melted, cut a tiny snip in the corner, and you’re set to go.
Kid-friendly version: Substitute part or all of the chocolate chips for mini chocolate lentils.
