Preheat the waffle iron.
Cream together the butter and sugar and smooth. Beat in the eggs and vanilla until smooth and set aside.
½ cup salted butter, 1 cup light brown sugar, 2 large eggs, 1½ teaspoon vanilla extract
In a separate bowl, whisk together the flour, baking powder, and salt.
1½ cups all-purpose flour, 1 teaspoon baking powder, ¼ teaspoon salt
Add the dry ingredients to the wet ingredients a little at a time, mixing just until combined then mix in the oil. Even though these will end up looking like mini waffles, the batter is thicker.
3 tablespoons cooking oil
Drop heaping tablespoons of the batter onto the greased waffle iron, leaving a little space between each cookie.
Cook until golden, about 1 to 2 minutes.
Remove using a fork, they will be soft at first then harden a bit more as they cool.
Sprinkle with powdered sugar if desired.
Powdered sugar is an optional garnish
