Either way, they always look beautiful on a dessert table.

How to Make Lemon Bars
Step One: Prepare the Oven and Pan
Preheat the oven to 350˚F. Lightly grease an 8-inch-by-8-inch baking pan or line with parchment paper.
Step Two: Mix the Dry Ingredients
In a small bowl, stir together the flour and salt. Set aside.
Step Three: Make the Crust
In a large bowl, beat butter until smooth. Add powdered sugar and brown sugar and beat until light and fluffy. Mix in the flour mixture until just combined. Press dough into the bottom of the pan and slightly up the sides.
Step Four: Bake the Crust
Bake for 15 to 20 minutes, or until lightly golden around the edges.
Step Five: Make the Filling
In a large bowl, whisk together eggs, egg yolk, sugar, flour, lemon zest, and lemon juice until smooth.

Reduce oven temperature to 300˚F. Pour filling over the hot crust and bake for 25 to 30 minutes, until set. Cool, then refrigerate for at least 2 to 3 hours. Dust with powdered sugar before serving.

Serving Suggestions
- Serve chilled or slightly cool for the best texture and flavor.
- Pair with coffee, tea, or even a light dessert wine.
- Add fresh berries like strawberries or blueberries on the side.
- Top with whipped cream for a little extra indulgence.
Quick Tips for Best Results
- Be sure to chill the bars completely before cutting so you get clean slices. I love to refrigerate overnight before serving.
- Use fresh lemon juice and zest for the best flavor. Bottled juice won’t give the same brightness.
- Don’t overbake the filling. It should be set but still slightly soft in the center.
- Line your pan with parchment for easy removal and cleaner cuts.
