There’s something about baking that feels like tucking the house into a warm blanket — and these strawberry lemon blondies are my favorite bedtime story. I remember pulling a pan from the oven on a rain-soaked afternoon and the whole kitchen smelled like bright lemon and warm sugar; my mom handed me a warm square and I felt like I’d swallowed summer. I make these when I want a little sunshine in my week: the crumb snaps at the edges, the center stays chewy, and juicy bits of strawberry pop like tiny flavor fireworks. They comfort, cheer, and somehow manage to be fancy without the fuss — exactly my kind of baking.

Why This Recipe is Awesome
These blondies marry bright **lemon** with sweet **strawberries** and buttery, chewy cake — think lemon bars met blondies and decided to go on a picnic. They bake fast, smell incredible (that lemon zing!), and hold together well for slicing or handing out at potlucks. They’re so straightforward even your oven can’t mess them up — and those golden edges? Total crowd-pleasers.
Ingredients
For the Main Dish:
- 1 cup all-purpose flour
- 1/2 tsp baking powder
- 1/4 tsp fine sea salt
- 1/2 cup unsalted butter (1 stick), melted and slightly cooled
- 3/4 cup granulated sugar
- 1/4 cup light brown sugar, packed
- 1 large egg
- 1 tsp pure vanilla extract
- 1 tbsp fresh lemon zest (about 1 medium lemon)
- 1 tbsp fresh lemon juice
- 1 cup hulled and roughly chopped fresh strawberries (firm, not mushy)
- 1/2 cup white chocolate chips or chopped white chocolate (optional but lovely)
For the Sauce / Garnish (optional):
- 1 cup powdered sugar
- 1–2 tbsp fresh lemon juice (to thin)
- Extra sliced strawberries or mint for garnish
How I Make It
Step 1:
I preheat the oven to 350°F and line an 8×8-inch baking pan with parchment, leaving a little overhang for easy lifting. While the oven wakes up, I whisk 1 cup flour, 1/2 tsp baking powder, and 1/4 tsp salt in a bowl to keep the dry mix airy and clump-free.
Step 2:
In a larger bowl I stir together the melted 1/2 cup butter, 3/4 cup granulated sugar, and 1/4 cup brown sugar until glossy. Then I add the egg, 1 tsp vanilla, 1 tbsp lemon zest, and 1 tbsp lemon juice, beating until the batter smells bright and citrusy. Tip: don’t overbeat the egg — mix until it just comes together.
Step 3:
I fold the dry ingredients into the wet with a spatula until the batter looks streak-free but still soft; then I gently fold in the 1 cup chopped strawberries and optional white chocolate chips. Expect pink streaks and juicy flecks — the batter should glisten and smell like lemon-sweet heaven.
Step 4:
I spread the batter into the prepared pan, smoothing the top with an offset spatula. I bake for 28–32 minutes, or until the edges turn golden and a toothpick comes out with a few moist crumbs (not wet batter). You’ll hear a gentle crackle as the top sets — that’s a good sign. If strawberries sit on top and brown too fast, tent foil loosely halfway through.
Step 5:
I cool the blondies in the pan for about 15 minutes, then lift them out on the parchment and cool another 20 minutes before slicing. For the glaze, I whisk 1 cup powdered sugar with 1–2 tbsp lemon juice until pourable, drizzle it over cooled blondies, and finish with sliced strawberries or mint. The first bite should give you crisp edges, a chewy center, and a bright lemon kick.
Pro Tips
- Use room-temperature egg for a smoother batter and even rise.
- Pat strawberries dry before chopping so they don’t water down the batter — too much moisture makes a gummy center.
- If you want extra chew, swap 2 tbsp of the flour for an equal amount of quick oats.
- To get clean slices, chill the blondies completely, then cut with a sharp knife warmed under hot water and wiped dry between cuts.
Common Mistakes to Avoid
- Skipping preheating: Classic rookie move. It changes texture and bake time.
- Overmixing: Leads to dense or chewy results. Mix until just combined.
- Guessing cook time: Always use visual cues or a timer, not just vibes.
- Overcrowding pans: Give your food some breathing room to crisp properly.
Alternatives & Substitutions
- Butter → coconut oil (use 3/4 cup oil for 1 cup butter). You’ll lose some buttery richness but keep a lovely texture.
- White chocolate → dark chocolate or chopped toasted almonds for contrast in sweetness and a nutty crunch.
- All-purpose flour → 1:1 gluten-free flour blend for a gluten-free version; texture may be slightly more crumbly.
- Dairy-free option: use vegan butter and dairy-free white chocolate to make these fully dairy-free.
Variations & Tips
- Add 1/2 tsp ground ginger for a spicy-sweet lift that plays nicely with lemon.
- Swap strawberries for blueberries for a classic lemon-blueberry combo.
- Stir in 1/2 cup toasted shredded coconut and a pinch of salt for a tropical twist.
- Make them into bars: press batter into a 9×13 pan and bake 5–8 minutes less for thinner, chewier bars.
- For a grown-up version, sprinkle 1 tbsp limoncello over the warm blondies before glazing for a boozy sparkle.
FAQ (Frequently Asked Questions)
- Can I make this ahead of time?
- Yes! Store cooled blondies in an airtight container at room temperature for up to 3 days or refrigerate up to 5 days. Freeze slices individually wrapped for up to 2 months; thaw at room temperature. Rewarm briefly in a 350°F oven for 5–7 minutes if you like them warm.
- Can I double the recipe?
- Sure thing. Use a 9×13-inch pan and bake for about 22–28 minutes (watch edges and toothpick test), since a thinner layer cooks faster. Keep an eye on doneness.
- Can I substitute butter with oil?
- Technically yes, but you’ll miss that buttery magic. Use ¾ the amount of oil (so 6 tbsp oil for 8 tbsp butter) and expect a slightly different mouthfeel.
- How do I know it’s done?
- Look for golden edges and a set, slightly puffed top. A toothpick should come out with moist crumbs, not raw batter. The center will firm up as it cools.
- What if I don’t have ingredient X?
- No lemon? Use 1 tsp vanilla plus 1/2 tsp almond extract for a different but tasty profile. No fresh strawberries? Use frozen (thawed and drained) but pat them dry to remove excess moisture.
How I Like to Serve It
I slice these into generous squares and serve them warm with a scoop of vanilla ice cream or a dollop of whipped cream for dessert. They also shine at brunch alongside strong coffee or iced tea — the lemon makes them feel fresh enough for spring. For picnics and potlucks, I skip the glaze so they travel well and still taste amazing at room temp.
Notes
- Store blondies in an airtight container at room temp up to 3 days or in the fridge up to 5 days. Reheat briefly in a 350°F oven for a warm, just-baked feel.
- Not applicable for meat temps — these are purely sweet treats, so no internal meat temperature to worry about.
Final Thoughts
Closing: Now go impress someone — or just yourself — with a pan of bright, buttery strawberry lemon blondies. They bake fast, taste like sunshine, and make any ordinary day feel celebratory.
