Zesty Little Lineup

  • Shortbread Base
    • Flour gives the crust structure and creates that soft shortbread texture.
    • Powdered sugar adds sweetness while keeping the crust tender and delicate.
    • Cornstarch helps create a soft, melt-in-your-mouth crust.
    • Salted butter adds rich buttery flavor and brings the crust together beautifully.
  • Lemon Filling
    • Sugar balances the tart lemon flavor and sweetens the filling.
    • Flour helps thicken the filling so the bars set properly.
    • Lemon zest adds bold fresh lemon flavor and bright citrus aroma, it really make these bars shine, so do not skip it.
    • Lemon juice gives the bars their classic tangy lemon taste.  adds bold citrus flavor that bottled juice alone just cannot match.
    • Vanilla softens the tartness and adds warmth to the filling.
    • Eggs create the smooth custard-like texture and help the filling set while baking.

How to Make Lemon Bars

  1. Preheat oven, grease and line pan with parchment paper.
  2. Mix the base ingredients until crumbly, press into the pan, and bake (as directed below).
  3. While the crust bakes, whisk together the filling ingredients until smooth. Pour over the hot base and bake for 20 minutes, or until set.
  4. Cool completely before slicing

Bright Bar Baking Tips

  • Use fresh lemon juice and zest for the best flavor. Two lemons will produce enough lemon juice and zest for this recipe.
  • Be sure to blend the base ingredients well. The butter should be evenly distributed throughout the flour mixture to achieve a light and consistent base.
  • Pour the filling onto the crust while it is still hot to help the layers bake together best.
  • Try not to over bake either the base or the filling. The base should be only slightly turning brown, and the center of the filling should look set but still soft.
  • Chill well before slicing. Remove bars from pan using the parchment paper for the easy slicing and serving.
  • Wipe the knife between cuts to keep those lemon bars looking neat and pretty.

Sweet Citrus Storage Secrets

  • Refrigerate lemon bars in an airtight container for up to 5 days. They taste even better once chilled so they are perfect as a make ahead dessert.
  • If stacking the bars, be sure to place parchment paper between the layers to ensure they do not stick together.
  • You can also freeze lemon bars for up to 2 months. Just thaw overnight in the fridge, or for about an hour at room temperature, before serving.
  • A final sprinkle of powdered sugar right before serving gives them that fresh bakery finish every single time. Fresh berries, or a sprig of mint makes for beautiful presentation.
