Preparation Steps

• In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
• Beat in the eggs one at a time, then stir in the vanilla extract.
• In a separate bowl, whisk together the flour, baking powder, and salt.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
• In a small bowl, mix together the melted butter, brown sugar, and cinnamon for the filling.
• Take about half of the cookie dough and spread it evenly into a greased 9x13 inch baking dish.
• Spread the cinnamon sugar filling evenly over the cookie dough layer.
• Crumble the remaining cookie dough and sprinkle it over the cinnamon sugar filling.
• Bake in a preheated oven at 350°F (175°C) for 25-30 minutes, or until golden brown and set.
• While the cookies are baking, whisk together the powdered sugar, milk, and vanilla extract until smooth for the glaze.
• Let the cookies cool slightly in the baking dish before drizzling the glaze over the top.
• Cut into squares and serve warm.
