Grapefruit And Vanilla Blondies

Sara Coleman
These vibrant blondies are a delightful twist on a classic, combining the bright, citrusy zing of fresh grapefruit with the warm, comforting notes of vanilla. The result is a perfectly chewy, tangy-sweet bar that's both refreshing and decadently satisfying.

Ingredients

  • 0.5 cup unsalted butter melted and cooled slightly
  • 1 cup light brown sugar packed
  • 1 large egg room temperature
  • 2 tsp pure vanilla extract
  • 2 tbsp fresh grapefruit zest finely grated (from about 1 large grapefruit)
  • 2 tbsp fresh grapefruit juice
  • 1 cup all-purpose flour
  • 0.5 tsp baking powder
  • 0.25 tsp salt
  • 0.5 cup white chocolate chips
  • 2 tbsp turbinado sugar for sprinkling on top

Notes

Storage: Store cooled blondies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. Make-Ahead: The blondie batter can be made, poured into the pan, covered, and refrigerated for up to 24 hours before baking. Add 1-2 minutes to the bake time if baking straight from the fridge. Substitutions: For a stronger vanilla flavor, use the seeds from half a vanilla bean instead of extract. The white chocolate chips can be replaced with chopped macadamia nuts. Serving Suggestion: Serve with a dollop of whipped cream or a scoop of vanilla ice cream for an extra-special treat.
