Preheat your oven to 350°F (175°C). Line a 9×13 baking pan with parchment paper.
In a large bowl, cream the softened butter and sugar until light and fluffy.
Add eggs and vanilla extract, mixing until well combined.
In a separate bowl, whisk together flour, baking powder, and salt.
Gradually incorporate the dry ingredients into the wet mixture, stirring until just combined.
Spread the dough evenly into the prepared baking pan.
In a small bowl, combine 2 tablespoons sugar and 2 teaspoons cinnamon; sprinkle evenly over the dough.
Bake for 25–30 minutes, until golden brown and a toothpick inserted into the center comes out clean.
Cool completely before slicing into bars. Serve and enjoy!
Notes
Add chocolate chips, nuts, or a caramel drizzle for extra indulgence.
Store bars in an airtight container at room temperature for up to 4 days or freeze for up to 2 months.
