1. Preheat your oven to 350°F. Grease an 8×8 inch baking dish or line it with parchment paper for easy removal.
2. In a large bowl, whisk together the melted butter, sugar, and brown sugar until combined. Stir in the eggs and vanilla extract until smooth.
3. In a separate bowl, mix the flour, cinnamon, baking powder, and salt. Gradually add the dry ingredients into the wet mixture, stirring until just combined.
4. Pour the batter into the prepared baking dish, smoothing it into an even layer with a spatula.
5. In a small bowl, mix the cream cheese until smooth and creamy. Drop spoonfuls over the batter, then use a knife to swirl it gently through the mixture, creating a marbled effect.
6. Bake for 25-30 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean.
7. Allow the bars to cool in the pan for at least 15 minutes before transferring them to a wire rack to cool completely.
8. Dust with confectioners’ sugar before serving for an extra touch of sweetness.

As my mother, Elena, taught me, cooking is about intuition. If the kitchen fills with that unmistakable cinnamon fragrance and the tops are just turning golden, you know they’re ready!
