Strawberry Lemon Blondies

The first time I made these, I was experimenting with what seemed like an unlikely combination and ended up eating three straight from the pan while they were still slightly warm. There's something about that bright lemon cutting through the buttery sweetness that makes them completely impossible to resist.

My neighbor actually knocked on my door the day I was testing this recipe, following the scent of butter and citrus. I sent her home with a square, and she texted me five minutes later asking for the recipe because her husband had already declared them the best thing he'd ever tasted.

Ingredients

• 1 cup (225 g) unsalted butter, melted: The foundation of that rich chewy texture we're chasing
• 1 cup (200 g) granulated sugar: Creates that beautiful crackly top
• 1/2 cup (100 g) light brown sugar, packed: Adds depth and keeps things moist
• 2 large eggs: Room temperature eggs incorporate better every single time
• 2 teaspoons pure vanilla extract: Don't skimp here
• Zest of 1 large lemon: Use a microplane to get just the bright yellow part
• 2 tablespoons fresh lemon juice: Fresh lemons make all the difference
• 2 cups (250 g) all-purpose flour: Spoon and level instead of scooping directly
• 1/2 teaspoon baking powder: Just enough lift without making them cakey
• 1/2 teaspoon salt: Balances and enhances all the sweetness
• 1 cup (150 g) fresh strawberries, diced: Chop them into small pieces so they distribute evenly
• 1 cup (120 g) powdered sugar, sifted: For the glaze
• 2–3 tablespoons fresh lemon juice: Adjust to get your perfect glaze consistency

Instructions

Get your oven ready:

Preheat to 350°F (175°C) and line an 8x8-inch pan with parchment paper, leaving those wings hanging over the sides like a little sling for easy lifting later.

Whisk your butter and sugars:

In a large bowl, combine melted butter with both sugars until everything's smooth and glossy.

Add the wet ingredients:

Whisk in eggs, vanilla, lemon zest, and juice until the mixture is uniformly combined.

Bring in the dry ingredients:

Fold in flour, baking powder, and salt until just incorporated.

Gentle does it:

Fold in those diced strawberries carefully so they don't get smashed or bleed too much.

Spread and bake:

Even out the batter in your prepared pan and bake for 28 to 32 minutes until the top is set.

The patience test:

A toothpick should come out with a few moist crumbs but not wet batter.

Cool completely:

Let them cool completely in the pan on a wire rack.

Make the magic glaze:

Whisk powdered sugar with lemon juice until smooth and pourable.

Finish strong:

Drizzle that glaze all over the cooled blondies, let it set for 15 minutes, then cut into squares and try not to eat them all at once.

My sister requested these for her baby shower and I made four batches because everyone kept sneaking them from the kitchen. There's something about that combination of bright citrus and sweet berries that feels like sunshine on a plate.

Making Them Your Own

I've swapped in raspberries when strawberries weren't in season, and honestly, that tangy raspberry lemon combo might be even better. Blueberries work beautifully too and hold their shape nicely through baking.

Storage Secrets

These actually taste better on day two when the flavors have had time to mingle and that glaze has soaked into the top layer slightly. Store them airtight at room temperature for up to three days.

Serving Suggestions

A scoop of vanilla ice cream turns these into an incredible dessert. They're also perfect with afternoon tea or coffee.

• Serve slightly warmed for extra gooeyness
• Add a pinch of lemon zest to the glaze for extra brightness
• Cut them small because they're rich

Every spring I make a batch the moment strawberries show up at the farmers market, and it's officially become the dessert my family requests most often.

Recipe FAQs

→ Can I use frozen strawberries instead of fresh?

Fresh strawberries work best as frozen ones release excess moisture during baking, which can make the blondies soggy. If you must use frozen, thaw them completely and pat them thoroughly dry with paper towels before folding into the batter.

→ How should I store these blondies?

Store in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week. You can also freeze individual squares wrapped tightly in plastic wrap for up to 3 months. The glaze may soften slightly at room temperature.

→ Why did my blondies turn out dry?

Overbaking is the most common cause. Start checking at 28 minutes and remove when a toothpick comes out with a few moist crumbs, not completely clean. Also, measure flour correctly by spooning it into the measuring cup and leveling off, rather than scooping directly.

→ Can I make these ahead of time?

Yes! You can bake the blondies up to 2 days ahead and store them unfrosted. Add the lemon glaze the day you plan to serve them for the freshest appearance. The unglazed blondies also freeze beautifully if wrapped well.

→ What other fruits work well in this recipe?

Raspberries, blueberries, or chopped peaches are excellent substitutes. Berries with similar moisture content work best. Avoid very juicy fruits like watermelon or extremely ripe stone fruits unless you reduce the amount slightly to prevent excess moisture.
