Preheat the waffle maker to low heat according to the manufacturer’s instructions.

Whisk together the flour, baking powder, baking soda, and salt. Set aside.

In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla extract until well combined.

Gradually add the dry ingredients to the butter mixture, mixing until just combined. Be careful not to over-mix.

If desired, fold in any optional mix-ins like chocolate chips, nuts, or sprinkles.

Drop tablespoonfuls of dough onto the preheated waffle maker, spacing them out as you would for regular waffles. Close the waffle maker and cook for about 2 to 3 minutes, or until the cookies are golden brown and cooked through.*

Carefully remove the cookies from the waffle maker and let them cool on a wire rack. Repeat with remaining dough. Serve warm or at room temperature.

Garnish if desired with confectioners’ sugar.
