Step-by-Step Instructions
- Preheat the oven to 350°F (175°C) and line a 9x13-inch baking dish with parchment paper.
- In a large mixing bowl, cream together the softened unsalted butter, granulated sugar, and brown sugar until light and fluffy for about 3-5 minutes.
- In a separate bowl, whisk together the all-purpose flour, baking powder, cinnamon, and salt. Gradually add this dry mixture to the butter mixture until just incorporated.
- Add eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
- In a small bowl, mix the additional brown sugar and cinnamon for the cinnamon swirl.
- Spread half of the batter in the prepared baking dish and sprinkle the cinnamon swirl mixture over it. Dollop the remaining batter on top and swirl gently.
- Bake for 25-30 minutes until the edges are golden brown and a toothpick comes out clean.
- Prepare the frosting by mixing powdered sugar, butter, vanilla, and milk until smooth. Adjust consistency as needed.
- Once cooled, frost the bars evenly, slice into squares, and enjoy.
