Oatmeal-Chocolate Chip Waffle Cookies

Baking cookie dough in a waffle iron takes about a minute and a half, a real time-saver when you've got to have warm cookies right away. These cookies, excerpted from the book Dessert Express, look like mini waffles, but they bake up just like oatmeal-chocolate chip cookies, with browned, toasty oats on the outside and gooey, melty chips. Once cooled, they look cute garnishing bowls of ice cream. 

Yields 24 cookies.

1/2 cup (1 stick) unsalted butter, melted
1/2 cup plus 2 Tbs. firmly packed light brown sugar
2 large eggs
1 tsp. vanilla extract
3/4 cup unbleached all-purpose flour
1/2 tsp. baking soda
1/4 tsp. salt
1-1/2 cups old-fashioned rolled oats (not instant)
1 cup semisweet chocolate chips
Nonstick cooking spray

Heat the waffle iron according to the manufacturer's instructions.
In a large bowl, whisk the butter and brown sugar until smooth. Whisk in the eggs and vanilla. Stir in the flour, baking soda, and salt. Stir in the oats and chocolate chips.
Coat the grids of the waffle iron with nonstick cooking spray. Use a tablespoon or small ice cream scoop to portion out a cookie onto each waffle square. Close the iron and cook until set and beginning to brown, 1-1/2 to 3 minutes, depending on the heat of your waffle iron. Use a thin metal spatula to transfer the cooked cookies to a wire rack and repeat with the remaining dough, coating the grids with spray as necessary.
