Ingredients Needed
Here are some notes on the ingredients we'll be using. For the full ingredients list, look at the recipe card below.
- All-Purpose Flour: The base and structure for the crust. A little is used in the lemon filling for thickness.
- Unsalted Butter: This gives the shortbread crust a delicious buttery flavor.
- Baking Powder: Helps the bars to slightly rise when baking.
- Lemons: Using both fresh lemon juice and zest will provide a very lemony filling. Do not use store-bought lemon juice
- Eggs: 3 large eggs are used to provide body to the filling.
Instructions
Here are the step by step instructions on how to make these homemade lemon bars.
Step 1: Make the crust. In a medium bowl, mix together the flour, melted butter, powdered sugar, vanilla extract, and salt using a wooden spoon.
Then press the crust into the prepared baking pan and bake for 16-20 minutes, or until lightly golden brown.
Step 2: Make the filling. In a large bowl, whisk together the sugar, flour, baking powder, and salt. Then mix in the fresh lemon juice, lemon zest, and eggs until combined.
Step 3: Bake. Reduce the oven temperature to 325 degrees and pour the lemon mixture over the hot crust. Bake for 15-18 minutes or until the middle is set.
Step 4: Cool the bars. Allow the bars to cool for 1 hour at room temperature and then for an additional 2 hours in the refrigerator.
Step 5: Serve. Dust with powdered sugar once completely cooled and slice into bars.
Storage Tips
Keep any leftover lemon squares in an airtight container in the refrigerator for up to 5 days.
You could also cover your pan with plastic wrap to help keep the bars fresh.
Expert Baking Tips
- Baking Pan: Line an 8x8-inch baking pan with aluminum foil, allowing a little to come up the sides. This will help with removing the bars. Then generously spray the foil and the sides of the pan with non-stick spray.
- Lemons: Use fresh lemons for this recipe. It has the best flavor, plus you'll need the zest as well. You'll need about 3 medium-sized lemons.
- Lemon Squeezer: I highly recommend this lemon squeezer. It's a lifesaver for me when I bake anything with lemons! Plus, you can use it for other citrus fruit as well.
- Oven Temperature: The crust will be baked at 350 degrees. Then lower the temperature to 325 degrees when the lemon layer is added to the crust. This helps the lemon filling to not overcook.
- Cooling: Before slicing and serving, the bars need to be completely cooled and set. Cool at room temperature for 1 hour, and then an additional 2 hours in the refrigerator.

Omg, these look amazingly good! I haven't made lemon bars in so long but now I have to. I love lemon baked goods and know I will love these too!
I use parchment paper to line my tin but never grease it.
I don’t sprinkle the icing sugar on them until I am serving them. Looks nicer. I always have my filled shaker handy.
These are delicious.
