Ingredients Method Notes

Ingredients
  

  • Ingredients You’ll Need
  • For the Blondie Base
  • 1 cup unsalted butter melted and cooled slightly
  • 1 ½ cups light brown sugar packed
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • For the Add-Ins
  • ¾ cup white chocolate chunks or chips
  • 1 cup raspberries fresh or frozen—keep frozen berries solid, don’t thaw

Method
 

1. Get Your Oven Ready

Set your oven to 350°F (175°C). Line a 9×9-inch pan with parchment paper, letting the edges hang over the sides. This makes lifting and slicing way easier later.

    2. Build the Base

    In a large bowl, whisk together the melted butter and brown sugar until smooth and glossy. Add the eggs and vanilla, then whisk again until everything looks thick and cohesive.

      3. Bring in the Dry Ingredients

      Add the flour, baking powder, and salt. Stir gently with a spatula until just combined. Don’t overmix—this keeps your blondies soft, not tough.

        4. Fold in the Good Stuff

        Mix in most of the white chocolate, saving a little for the top. Gently fold in half of the raspberries.

          5. Create That Swirl Magic

          Spread the batter evenly into your pan. Sprinkle the remaining raspberries and white chocolate over the top. Use a knife or skewer to swirl lightly.

            Tip: Keep the swirls loose for that pretty marbled look—no overdoing it.

          6. Bake to Perfection

          Bake for 35–40 minutes until the edges turn golden and the center looks set. A toothpick should come out with a few moist crumbs (not wet batter).

            7. Cool Before Cutting

            Let the blondies cool completely in the pan. Then lift them out and slice into squares.

              Serving Ideas That Hit Different

              • Serve at room temp for soft, buttery bites
              • Chill them for a firmer, chewy texture
              • Warm one slightly and add vanilla ice cream (highly recommend)
              • Pair with coffee or iced latte for an easy dessert moment

              Expert Tips for Perfect Blondies

              • Use room-temp eggs so the batter blends smoothly
              • Keep frozen raspberries frozen to avoid excess moisture
              • Don’t overbake—the center should stay slightly soft
              • Line your pan properly for clean, easy removal
              • Let them cool fully before slicing for neat squares

              Storage & Make-Ahead Tips

              • Store in an airtight container at room temperature for up to 3 days
              • Refrigerate for up to 1 week (they get extra chewy!)
              • Freeze individually wrapped squares for up to 2 months
              • Thaw at room temp for about an hour before serving

              Frequently Asked Questions

              Can I use frozen raspberries?
               Yes—just don’t thaw them. They’ll hold their shape better in the batter.
              Why are my blondies too dense?
               You may have overmixed the batter. Keep it gentle once the flour goes in.
              Can I swap white chocolate?
               Absolutely. Try dark or milk chocolate for a different twist.
              How do I get a perfect swirl?
