Ingredients Method

Ingredients

  

• 1 cup (225 g) unsalted butter, melted and slightly cooled
• 1 1/2 cups (300 g) light brown sugar, packed
• 1/2 cup (100 g) granulated sugar
• 2 large eggs, room temperature
• 1 large egg yolk, room temperature
• 1 tablespoon vanilla extract
• 2 cups (250 g) all-purpose flour
• 1/2 teaspoon baking powder
• 1/2 teaspoon fine sea salt
• 1 cup (170 g) white chocolate chips or chopped white chocolate
• 1 1/2 cups (180 g) fresh raspberries (or frozen, unthawed)
• Optional: Zest of 1 lemon for brightness

Method

 

1. Prep the pan: Heat the oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment, leaving overhang for easy lifting. Lightly grease the parchment.
2. Melt the butter: Melt the butter and let it cool for 5–7 minutes until warm but not hot. This helps keep the blondies thick and fudgy.
3. Mix sugars and butter: In a large bowl, whisk the melted butter with the brown sugar and granulated sugar until glossy and well combined, about 45 seconds.
4. Add eggs and vanilla: Whisk in the eggs, egg yolk, and vanilla (and lemon zest if using) until the mixture thickens slightly and looks smooth.
5. Combine dry ingredients: In a separate bowl, whisk the flour, baking powder, and salt. Add to the wet mixture and fold gently with a spatula until just combined. Do not overmix.
6. Stir in the chocolate: Fold in the white chocolate, reserving a small handful for the top.
7. Add raspberries: Gently fold in the raspberries with 2–3 light strokes. It’s fine if some streak and break; avoid overmixing so the batter doesn’t turn purple.
8. Spread and top: Scrape the batter into the prepared pan and smooth the top. Sprinkle the reserved white chocolate over the surface.
9. Bake: Bake for 28–34 minutes, until the edges are golden, the top is set, and a toothpick inserted near the center comes out with a few moist crumbs (not wet batter).
10. Cool and slice: Let the blondies cool in the pan on a rack for at least 1 hour. Lift out using the parchment and cut into squares. For the cleanest cuts, chill for 30 minutes first.

Benefits of This Recipe

• Reliable results: The ingredient ratios produce a consistent chewy texture.
• Flexible ingredients: Fresh or frozen raspberries both work, and you can use chips or chopped bars.
• Make-ahead friendly: Flavor deepens by day two, making them great for events.
• Crowd-pleasing flavor: Sweet, tart, buttery, and just a little fancy without extra effort.

Pitfalls to Watch Out For

• Overbaking: This is the fastest way to dry blondies out.

  Pull them when the center still looks slightly soft.

• Hot butter + eggs: If the butter is too hot, it can scramble the eggs. Let it cool a bit before mixing.
• Overmixing the batter: Too much stirring develops gluten, leading to tough blondies and smashed raspberries.
• Watery fruit: If using very juicy raspberries, don’t rinse right before mixing. Pat dry to prevent soggy pockets.
• Wrong pan size: A smaller pan makes the centers underbaked and edges overbaked.

  Stick to 9×13 for even results.

Variations You Can Try

• Almond twist: Add 1/2 teaspoon almond extract and sprinkle sliced almonds on top.
• Lemon-raspberry: Add zest of 1–2 lemons and a squeeze of lemon juice to brighten the batter.
• Ruby swirl: Warm 2 tablespoons raspberry jam and swirl over the batter before baking.
• Brown butter: Brown the butter for a deeper, nutty flavor. Let it cool before mixing.
• Mixed berries: Use a blend of raspberries and blueberries for a pretty speckled look.
• Gluten-free: Substitute a 1:1 gluten-free all-purpose flour blend designed for baking.
• Extra gooey: Reduce baking time by 2–3 minutes and chill before slicing.

FAQ

Can I Use Frozen Raspberries?

Yes. Use them straight from the freezer and fold in gently.

Do not thaw first, or they’ll bleed too much juice into the batter.

How Do I Know When They’re Done?

Look for golden edges and a set, slightly shiny top. A toothpick inserted near the center should come out with moist crumbs, not wet batter.

Can I Reduce the Sugar?

You can cut up to 1/4 cup of granulated sugar without major changes, but the texture may be less fudgy. Brown sugar contributes to chew, so keep most of it.

What If I Don’t Have White Chocolate Chips?

Chop a good-quality white chocolate bar into small chunks.

It melts more luxuriously and gives nice pockets of creaminess.

Do I Need to Refrigerate Them?

Not required, but chilling helps them set and makes cleaner slices. If your kitchen is warm, refrigeration can keep them fresher longer.

Why Add an Extra Egg Yolk?

The extra yolk adds richness and tenderness, helping the blondies stay chewy and moist without becoming cakey.

Can I Halve the Recipe?

Yes. Bake in an 8×8-inch pan for about 24–28 minutes, checking early.

The same cues for doneness apply.
