Step-by-step instructions:

  1. First, make the easy shortbread crust. Simply combine the dry ingredients together, and then cut in the butter using a pastry blender or two knives. The dough should resemble coarse crumbs. With your fingertips, press the dough into a greased or foil- or parchment-lined pan. Try and get the crust as even as possible. You can press a flat-bottomed glass on the dough to really smooth the surface down.

  2. Bake the crust at 350 degrees for 18-20 minutes or until the edges are golden. While the crust bakes, make the filling. It’s easy. Mix the eggs, sugar, small amount of flour, cream, lemon juice, zest, together until creamy. Pour the filling over the hot crust.

  3. Pop everything back in the oven for another 15 minutes. The center should look ‘set’ when you take it out of the oven. Let the bars cool before sprinkling with powdered sugar. Then cut into square for lemon squares, triangles for lemon triangles, or bar shapes for, you know, lemon bars.

Recipe tips and variations:

  • Lemon juice yield: One lemon yields roughly 2 tablespoons of lemon juice and 1 teaspoon zest. To make one batch of bars, you’ll need 12 tablespoons, so buy at least 6 lemons.
  • Juicy: To squeeze every drop of lemon juice out of each fruit, roll thrm on the counter roughly, pressing hard on each lemon. This will help to loosen up the juices before squeezing.
  • Chill before slicing: They cut like a dream when they’re cold, so I suggest you chill them before cutting.
  • Gluten-free: It’s the easiest thing in the world! You can make gluten-free lemon bars by switching out your favorite GF flour. It should turn out beautifully.
  • Bottled lemon juice: Fresh juice is recommended, but sometimes you need lemon bars and all you have is the bottle. If a recipe calls for the juice of 1 lemon, you can substitute 2 tablespoons of bottled juice.
  • Make ahead: These are fine made ahead, lightly wrapped, and stored in the refrigerator.
  • Storing: Since lemon bars are made with a custard (egg and dairy), you need to refrigerate them. They are fine to serve at room temperature if made the same day, or left out a few hours if they are on a dessert plate at a party.
  • Freezing: To freeze, cut and wrap each bar individually in waxed paper or plastic wrap, then stow away in a freezer bag to pull out when you need a little sunshine in your life.
