Equipment

  • Pastry Cutter
  • 9x13 inch Pan
  • Large mixing bowl

Ingredients

  • 2 cups flour
  • ½ cup powdered sugar
  • 1 cup salted butter softened4 eggs
  • 2 cups white sugar
  • cup lemon juice freshly squeezed
  • ½ cup flour
  • ½ teaspoon baking powder
  • ½ teaspoon lemon zest
  • extra powdered sugar for dusting

Instructions

  • Preheat the oven to 350 degrees F.
  • In a large bowl, combine the flour and sugar.
  • Cut the softened butter stick into four pieces and add it to the bowl of sugar and flour. Using a pastry cutter, cut the butter into the mixture until it clings together and is crumbly.
  • Pour the shortbread crust into a 9X13 inch glass baking pan and press in until the bottom is covered evenly.
  • Bake the crust for 20 to 25 minutes, until just turning golden. Remove from the oven to set aside and cool.
  • While the crust is baking, make the filling. In a large mixing bowl, use an electric hand mixer to whisk together the eggs, white sugar, and lemon juice.
  • In a separate bowl, combine the flour, baking powder and lemon zest. Add these dry ingredients to the egg mixture and mix together. The batter will be very runny.
  • Pour the lemon batter evenly over the baked, cooled crust.
  • Bake for approximately 25 minutes. It should be a light golden brown.
  • Remove it from the oven and allow it to cool before cutting and serving.
  • Dust the top of the bars with powdered sugar (try using a fine sieve or sifter) and cut into squares.

Notes

Storage and Reheating Instructions:

How to Store Lemon Bars:

These will keep beautifully in the fridge for up to a week.  Just use parchment paper to separate the layers if you have to stack them in a container.  Keep them in an airtight container.  Or, you may freeze them for up to 3 months. 

How to Reheat Lemon Bars:

Reheating isn't necessary but if you prefer your Lemon Bars a bit on the warmer side, a quick zap in the microwave will do the trick—just be careful not to melt that sugary top.

Helpful Tips & Substitutions

Can This Be Frozen?

Absolutely! Wrap individual bars in plastic wrap and then place them in a freezer bag. They'll last for about three months. Thaw them in the fridge or on the counter when you're ready for a treat.

Can This Be Made Ahead of Time?

Yes, and you should! Making them a day ahead allows the flavors to meld together beautifully. Just store them in the fridge until you're ready to serve.

Substitutions & Variations

  • Gluten-Free? Swap the flour for your favorite GF blend.
  • Vegan? There are great vegan butter and egg substitutes out there.
  • Love Orange? Use orange juice and zest for a citrusy twist.

Helpful Cooking Notes

  • Lemon Zest: Don't skip it! It adds an irreplaceable depth of flavor.
  • Cutting Bars: Use a hot knife for clean cuts. Dip it in hot water, wipe quickly, and slice.
  • Sifting Sugar: For an even dusting of powdered sugar, use a fine sieve or sifter.
