Ingredient Notes & Tips

Here’s how to get the best flavor and texture from each component:

Butter

Use softened, unsalted butter for the crust. This ensures a smooth, creamy base and better control over salt levels.

Powdered Sugar

Used in the crust for a softer, more delicate texture compared to granulated sugar.

All-Purpose Flour

Provides structure for both the crust and filling. Be sure to measure correctly (spoon and level) to avoid a dense crust.

Eggs

Room temperature eggs mix more smoothly and help create that luscious, custard-like lemon layer.

Granulated Sugar

Sweetens the filling and balances the tartness of the lemon.

Lemon Juice & Zest

Fresh is best! Bottled juice won’t give the same bright flavor.

  • Zest adds intense citrus aroma
  • Juice provides that signature tang

Baking Powder

A small amount helps give the filling a slight lift so it’s not too dense.

How to Make Lemon Bars

1. Prepare the Crust

Cream together butter and powdered sugar, then mix in flour. Press evenly into a greased 9×13-inch pan and bake at 350°F for 20 minutes.

2. Make the Filling

Whisk eggs until light, then gradually add sugar. Mix in lemon zest, lemon juice, flour, and baking powder until smooth.

3. Bake Again

Pour the filling over the hot crust and bake another 15–20 minutes, until set and lightly golden.

4. Cool & Dust

Let cool, then dust with powdered sugar while slightly warm. Slice into bars once fully cooled.

Frequently Asked Questions

Why are my lemon bars runny?

They likely needed more baking time. The center should be set and not jiggle when gently shaken.

Can I use bottled lemon juice?

You can, but fresh lemon juice is strongly recommended for the best flavor.

How do I get clean cuts?

Let the bars cool completely, then use a sharp knife wiped clean between cuts.

Can I make these ahead of time?

Yes! These are perfect for making a day in advance. Chill and dust with sugar before serving.

Do lemon bars need to be refrigerated?

They can sit out briefly, but refrigeration keeps them fresher longer and improves texture.
