Step-by-Step Instructions
- Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan with butter or non-stick spray.
- Cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes.
- Add the eggs, sour cream, and vanilla extract to the creamed mixture and mix until well combined.
- Whisk together the all-purpose flour, baking powder, baking soda, ground cinnamon, and salt in a separate bowl.
- Gradually add the dry flour mixture to the wet ingredients, stirring gently until just combined.
- Transfer the batter into the greased baking pan and spread it evenly across the bottom.
- Mix together some additional cinnamon and granulated sugar for topping and sprinkle it generously over the batter.
- Bake for 25-30 minutes until a toothpick inserted into the center comes out clean and the edges are golden brown.
- Remove the pan from the oven and let the bars cool completely in the pan.
- Prepare the frosting by combining powdered sugar, milk, and vanilla extract until smooth.
- Drizzle or spread the frosting over the cooled bars and let it set for a few minutes before slicing into squares.
