Can I use store-bought lemon curd?

Absolutely. Homemade lemon curd is wonderful, but store-bought works beautifully and saves time. This recipe is all about ease.

How do I store Lemon Curd Blondie Bars?

Store them in an airtight container at room temperature for up to 3 days. If your kitchen runs warm, you can refrigerate them—just let them sit out a bit before serving so they soften.

Can I double the recipe?

Yes! Use a 9x13 pan instead of an 8x8. The batter will spread more evenly, and you’ll get more bars for gatherings, potlucks, or bake sales.

Can I use whole wheat pastry flour?

It’s best to stick with all-purpose flour for the softest texture. Whole wheat pastry flour can make them slightly dense.

How do I know when they’re done?

Look for lightly golden edges and a center that doesn’t jiggle when gently shaken. A toothpick should come out mostly clean with a few moist crumbs.

Instructions

Preheat oven to 350°F. Line an 8×8 baking pan with parchment paper, leaving overhang on all sides.
In a large bowl, beat butter, granulated sugar, and brown sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition. Scrape down the bowl as needed.
Mix in salt, baking powder, and lemon zest.
Add lemon curd one tablespoon at a time, mixing until just combined.
Stir in flour and mix until fully incorporated with no streaks remaining.
Press batter evenly into the prepared pan.
Bake for 30 minutes, or until edges are lightly golden and the center is set.
Cool completely in the pan before lifting out using parchment overhang.
Slice into 9 equal bars and store in an airtight container.

Notes

Homemade or store-bought lemon curd both work well.

Do not overbake — the center should remain soft for the best texture.

For variation, add fresh blueberries and increase baking time by about 10 minutes.

A drizzle of melted white chocolate or a light dusting of powdered sugar adds a bakery-style finish.
