I published this recipe for Peach & Lemon Glazed Blondies a few years ago after a particularly fruitful trip to the farmer’s market. I came home with a basket of peaches so ripe they practically begged to be baked into something special. But I didn’t want a pie or a cobbler that day. I wanted something handheld, something with the chewy joy of a brownie but the bright, sunny flavor of spring.
My secret for this recipe is a two-part glaze. I know, it sounds like a tiny bit of extra work. But trust me, it makes all the difference. The first layer soaks right into the warm blondie, creating this incredibly moist crumb. The second layer sits on top, setting into a sweet, peachy shell that cracks with every bite. It’s my favorite trick for making a simple bar dessert feel absolutely extraordinary.

Why This Recipe is So Special
What sets these apart is how we treat the peaches. We’re not just folding chunks into the batter. Instead, we cook some down into a quick compote that gets swirled right in. This concentrates the flavor and keeps the blondies from getting soggy.
The lemon in the glaze is the other star. It cuts through the sweetness and makes the peach flavor pop in the most beautiful way. Together, they taste like a perfect spring afternoon in a pan.

Notes
Enjoy your homemade Peach & Lemon Glazed Blondies Recipe!
- First, make the peach swirl. In a small saucepan, combine the diced peaches, 2 tbsp sugar, and lemon juice. Cook over medium heat for 8-10 minutes, mashing with a fork, until thickened. Let it cool completely. Set aside 3 tablespoons for the glaze.
- Preheat your oven to 350°F (175°C). Line an 9×13 inch baking pan with parchment paper, leaving an overhang on the sides. This makes it so easy to lift out and slice later.
- In a large bowl, whisk the melted butter and brown sugar together. It will look a bit gritty, that’s perfect. Whisk in the eggs, egg yolk, and vanilla until the mixture is smooth and glossy.
- In a separate bowl, whisk the flour, baking powder, and salt. Gently fold the dry ingredients into the wet ingredients with a spatula. Mix just until no dry streaks remain. Overmixing is the enemy of a tender blondie.
- Spread about two-thirds of the blondie batter into your prepared pan. Dollop the cooled peach compote over the top. Then, spoon the remaining batter in blobs over the peaches. Use a knife or skewer to gently swirl everything together.
- Bake for 28-32 minutes, or until the top is golden and a toothpick inserted near the center comes out with just a few moist crumbs. Let the blondies cool in the pan on a wire rack for about 20 minutes.
- While they cool, make the glaze. Whisk the powdered sugar, the 3 tbsp of reserved peach compote, 2 tbsp lemon juice, and salt. Add the last tablespoon of lemon juice if you need it thinner. You want a thick but pourable consistency.
- Poke the warm blondies all over with a toothpick. Slowly pour half of the glaze over them, letting it seep into the holes. Let it set for 5 minutes, then pour the remaining glaze over the top. Let cool completely before slicing into squares.
My Top Tips for Success
- Use room temperature eggs. They blend into the butter and sugar much more smoothly, giving you a better texture. If you forget, place the cold eggs in a bowl of warm water for 5 minutes.
- Don’t skip the parchment paper! It’s the only surefire way to get clean, perfect squares without any sticking.
- Let the peach compote cool before adding it to the batter. A hot compote will start to cook the eggs in the batter and make a mess.
- For pretty swirls, don’t overdo it. Three or four figure-eight motions with your knife is plenty. We want ribbons of peach, not a fully mixed-in batter.
Common Mistakes to Avoid
The biggest mistake is overbaking. Blondies continue to cook as they cool in the pan. If you wait for a completely clean toothpick, they’ll be dry. Take them out when there are a few sticky crumbs attached.
Another common error is measuring flour incorrectly. Fluff your flour in the bag, spoon it into your measuring cup, and level it off with a knife. Scooping directly packs in too much flour and leads to dense bars.
Finally, don’t glaze the blondies while they are piping hot. If they’re too hot, the glaze will just melt and run off. That 20-minute cooling window is crucial for the glaze to stick properly.

FREQUENTLY ASKED QUESTIONS
Can I use frozen or canned peaches?
You can! Thaw and drain frozen peaches very well. For canned, use peaches in juice (not heavy syrup), drain them, and pat them completely dry with paper towels to remove excess moisture.
How should I store these blondies?
Keep them in an airtight container at room temperature for up to 3 days. The glaze will stay perfect. For longer storage, you can freeze them (without the glaze) for up to 2 months.
My glaze is too thin/thick. How can I fix it?
Too thin? Add more sifted powdered sugar, a tablespoon at a time. Too thick? Add more lemon juice, just a teaspoon at a time, until it reaches a pourable consistency.
