Variations For Best Lemon Bars

No bake lemon bars– Make the crust as directed. Then, mix together lemon pudding mix (mixed according to the package) and 8 oz of cool whip. Pour it into the crust and let is set in the fridge for up to 2 hours or over-night.

Lemon blueberry bars– Add some fresh blueberries to the curd mixture or you can swirl in some blueberry jam.

Meyer lemon bars– Use Meyer lemons for their vibrant flavor.

Try other crusts– Use this Graham Cracker Crust (No Bake) or this Oreo Cookie Crust (No Bake). You can also use a pretzel crust for a sweet and salty variation.

Add extracts– Such as almond, vanilla, or even lavender.

Add shredded coconut in the crust or lemon mixture- This adds texture and sweetness.

Mix in other berries– Such as blueberries, raspberries, strawberries, or even blackberries.

Add lavender– Don’t add a lot or else it will taste and smell like soap.

Use other citrus juice and zest– Like grapefruit, blood orange, regular oranges, or limes.

Tips And Techniques For Classic Old Fashioned Homemade Lemon Squares

Freshly squeezed lemon juice is best-Because it has the freshest, strongest, flavor and I highly recommend it.

Why are my lemon bars runny? How to fix it? This may mean that the bars are under-baked, in which case cook them a little longer, or they need to chill longer so that they set properly.

Why did my lemon bars crack? Either the eggs were over- mixed, or the bars were over-baked.

Why are my bars brown on top? The temperature may have been too high for baking, or they were over-baked.

Why are there white bubbles on top of bars? They are created from air the eggs release while baking. It is nothing to worry about, and the bubbles will be covered up by the powdered sugar on top anyways.

How do I know the these bars are done baking? They are done when the top is almost set and the center jiggles slightly.

Line pan with parchment paper– This is very important because it prevents the bars from sticking to the bottom of the pan, and makes for super easy clean-up.

What size pan to use? I use and recommend an 8×8 inch pan. This is the size pan that this recipe is designed for.

Do I have to chill the bars? Yes, cover the bars with plastic foil and chill in the fridge for 2 hours or overnight. Do not skip this step because it allows the filling to set further.

Let the crust cool before filling with curd– This ensures that the curd filling doesn’t seep into the crust and make it soggy and runny.
