The simple ingredients you need
To make the most sensational batch of these lemon raspberry blondies, you will need a handful of basic pantry staples along with some fresh produce. Here is exactly what to gather:
- Unsalted Butter
- Using melted unsalted butter is the secret to achieving that rich, chewy texture we all love in a blondie. It provides a beautiful buttery backdrop without making the dessert overly salty.
- Granulated Sugar
- We rely entirely on white granulated sugar for this recipe (instead of brown sugar) to allow the bright lemon flavor and vibrant raspberry colors to truly shine through. It also helps create that crackly top layer.
- Fresh Lemons
- You will need fresh lemons for both their zest and their juice. The zest holds essential oils that pack a massive flavor punch, while the fresh juice adds the perfect acidic tang to balance the sugar.
- Large Eggs
- Eggs bind the ingredients together and provide structure. Make sure your eggs are at room temperature so they incorporate seamlessly into the melted butter mixture.
- Vanilla Extract
- A splash of high-quality pure vanilla extract enhances all the other flavors and adds a subtle background warmth that complements the citrus and berries.
- All-Purpose Flour
- The standard structural base. Be sure to measure your flour using the spoon-and-level method rather than scooping directly from the bag to avoid dense, cakey blondies.
- Fresh or Frozen Raspberries
- Fresh raspberries are ideal, but frozen work wonderfully too! If using frozen, do not thaw them beforehand, or they will bleed too much color into the batter.
- Powdered Sugar & Raspberry Jam (For the Glaze)
- Also known as confectioners’ sugar, this creates a smooth, sweet, and perfectly drizzly glaze when combined with liquid. A spoonful of seedless raspberry jam mixed into the glaze gives it a gorgeous natural pink hue and an extra pop of berry flavor.
How to make this lemon raspberry blondies
- Preheat the oven: Preheat your oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving an overhang on the sides for easy removal later.
- Rub the sugar and zest: In a large mixing bowl, combine the granulated sugar and fresh lemon zest. Use your fingertips to massage the zest into the sugar until it is fragrant and resembles wet sand. This releases the oils and maximizes the lemon flavor.
- Whisk the wet ingredients: Pour the melted (and slightly cooled) butter into the lemon sugar. Whisk until well combined. Add the eggs, lemon juice, and vanilla extract, whisking vigorously until the mixture is smooth and slightly pale.
- Fold in the dry ingredients: Sprinkle the all-purpose flour and salt over the wet mixture. Use a rubber spatula to gently fold the ingredients together until just combined. Be careful not to overmix!
- Add the berries: Gently fold in the raspberries, taking care not to crush them too much. If using frozen berries, toss them in a teaspoon of flour first to prevent sinking.
- Bake the blondies: Pour the batter into your prepared pan and smooth the top. Bake for 30-35 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with moist crumbs.
- Cool completely: Let the blondies cool entirely in the pan on a wire rack. They will continue to set as they cool.
- Whisk the glaze: While the blondies cool, whisk together the powdered sugar, a splash of lemon juice, and a spoonful of raspberry jam until you reach a smooth, pourable consistency.
- Glaze and serve: Once the blondies are completely cool, lift them out of the pan using the parchment paper overhang. Drizzle the sweet glaze generously over the top, slice into squares, and enjoy!
Fun variations to try
While the classic recipe is absolute perfection, baking is all about making things your own. Here are a few delightful twists you can put on this dessert.
White Chocolate Chips
For an extra layer of creamy sweetness, fold half a cup of high-quality white chocolate chips into the batter along with the raspberries. The milky sweetness of the white chocolate pairs incredibly well with the tart lemon. Check out our Strawberry White Chocolate Sourdough Muffins for more inspiration!
Almond Extract
Swap out the vanilla extract for half a teaspoon of almond extract. Almond and raspberry are a classic flavor combination that will give these blondies a sophisticated, bakery-style profile.
Blueberry Lemon Blondies
Not a fan of raspberries? You can easily substitute them with fresh blueberries! The baking process remains exactly the same, and the result is just as delicious.
Serving Ideas
- Afternoon Treat: Serve a warm blondie alongside a piping hot cup of Earl Grey tea or a freshly brewed iced latte.
- Dinner Party Dessert: Plate a generous square with a large scoop of vanilla bean ice cream and an extra drizzle of raspberry puree.
- Spring Brunch: They make fantastic additions to a spread, complementing savory items beautifully. Pair them with a side of fresh fruit salads like our Tomato and Peach Salad, Smoky Watermelon Feta Salad.
Prep and storage advice
- Room Temperature: Store any leftover blondies in an airtight container for up to 2 days. Because they contain fresh fruit, they are slightly more delicate than a standard chocolate brownie.
- Refrigerator: Keep them in the fridge for up to 5 days. They are actually fantastic served chilled, as the texture becomes extra dense and fudgy!
- Freezer: Freeze them before adding the glaze. Wrap the completely cooled, uncut blondie block tightly in plastic wrap, then place it in a freezer-safe zip-top bag for up to 3 months.
- Thawing: Thaw overnight in the refrigerator, bring to room temperature, and then add your fresh glaze before slicing.

FAQs
Can I use bottled lemon juice instead of fresh?
While you can use bottled juice in a pinch, fresh lemon juice provides a significantly brighter, purer citrus flavor without any artificial aftertaste. Plus, you will need fresh lemons anyway to get the zest required for the recipe.
Why did my blondies sink in the middle?
Sinking typically happens for two reasons: either the blondies were underbaked, or the batter was overmixed. Ensure you only fold the dry ingredients until just combined, and always check for doneness with a toothpick before removing them from the oven.
Can I double this recipe for a larger crowd?
Yes, absolutely! You can double all the ingredients and bake the batter in a 9×13 inch rectangular baking pan. You may need to add 5-10 minutes to the overall baking time, so keep a close eye on them and use the toothpick test.
If you have been looking for the ultimate fruity, chewy, and vibrant dessert, you simply have to give this recipe a try.
