Instructions
Preheat the oven to 175°C (350°F). Line a square baking tin with parchment paper.
In a large bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth and glossy.
Add eggs and vanilla extract. Mix well until fully combined.
In another bowl, combine flour, baking powder, and salt.
Gradually fold the dry ingredients into the wet mixture. Avoid overmixing.
Stir in white chocolate chunks evenly throughout the batter.
Pour the batter into the prepared baking tin and smooth the surface.
Bake for 28–32 minutes until the edges are golden and the center is slightly soft.
Remove from the oven and allow the blondies to cool completely before slicing.
Cut into squares and serve warm or at room temperature.
Notes
Do not overbake, or the blondies may become dry.
Let the blondies cool fully for cleaner slices.
Use high-quality white chocolate for better flavor.
