Easy Lemon Bars Recipe
I’m pretty picky about my lemon bars. The filling, the crust, and the sweet-tart balance all has to be just right. I’m like Goldilocks with her porridge. These classic lemon bars are Goldilocks approved. Before making these, I researched dozens of recipes, studying each meticulously, but nothing sounded exactly perfect. I referenced one of my favorite cookbooks, The New Best Recipe, but when I saw seven eggs, I slammed the book shut immediately.Unless you’re feeding a football team, any one singular dessert does not need seven eggs, period. I also checked out another trusty resource, The King Arthur Flour Baker’s Companion, and many others. But in the end, I came up with my own. These classic lemon bars consist of an easy shortbread crust, topped with an intensely lemony filling. The tartness and sweetness are well-balanced. You don’t even have to lug out your mixer to make them.
Just as cornstarch helps cookies stay soft and tender, it does the same for the crust of these homemade lemon bars. Shortbread crusts tend to become too dry, hard, or tasteless, and remind me of dog biscuits, which is why I never make biscotti. I’m sorry for anyone who likes it but it’s so unsatisfying for me because I can’t get past that dry, hard-yet-crumbly dough. The cornstarch keeps this crust just a bit softer than some, preventing the cardboard phenomenon. Another notable difference in this classic lemon bar recipe is that the ratio of lemon juice ratio is much, much higher than in most recipes. For an 8-inch square pan, most call for two tablespoons whereas mine uses eight (one-half cup); four times the amount. You’d think this would make you pucker up up for days but really, it doesn’t. The bars are robustly lemon-flavored, but not ridiculous, and they’re how I think a lemon bar should be. If I wanted a blondie with a hint of lemon, I’d use two tablespoons of lemon juice, but I wanted a good old-fashioned lemon bar, full of zing and tang. But they’re also sweet enough to be considered dessert, not torture. The overall depth of lemon flavor is boosted from two teaspoons of lemon zest. Most recipes this size use one teaspoon, but I doubled it and used two. I also added a tiny bit of vanilla extract, something that isn’t traditional in lemon bars, but I love vanilla.
I am so pleased with these because the flavor is robustly lemony and tart, but they’re not sour, pungent, bitter, or overwhelming. They’re just sweet enough, but not too much. The sprinkling of confectioners’ sugar gives them a tiny bit of additional sweetness and gives them that classic lemon bar appearance. The filling itself is dense but light, almost like a lemon custard with a touch of creaminess. It’s smooth and firm, without being rubbery. The crust is buttery, just crisp enough, but retains some softness, flakiness, and tenderness. It’s a ever-so-slightly sweetened and thick enough to stand up to the layer of lemon filling and not be overwhelmed by it. I don’t like it when shortbread crusts are paper thin and prefer them on the thicker side. Not too thick, not too thin. Hello, Goldilocks. My almost six-year old is a lemon fanatic (heads up this is a repost from 2013 and she’s now 13!). She’ll reach into a water glass with a lemon, fish it out, and eat it. She loved these easy lemon bars because anything lemon-flavored is a hit with her. I wouldn’t call them The Best Lemon Bars if I didn’t really think they were.
What’s in the Best Lemon Bars?
To make the best ever lemon bars, you’ll need:
Unsalted butter All-purpose flour Confectioners’ sugar Cornstarch Salt Eggs Granulated sugar Half and half Lemon juice and zest Vanilla extract Lemon extract
How to Make Lemon Bars
Make the crust by combining all-purpose flour, confectioners’ sugar, and one tablespoon of cornstarch, with one stick of very soft butter in a medium bowl. The softer the butter is, the easier of a time you’ll have. You can do this with a food processor, but it comes together in just a minute by hand, which I prefer to washing out my food processor for such a fast little crust. The crust mixture will seem crumbly, but transfer the pea-sized lumps and crumbs to an 8-inch square foil-lined pan, and press them down until a smooth crust forms. Prick it haphazardly with a fork in a dozen places so the steam can escape, and bake it for 12 to 15 minutes. As it bakes, if you notice any big air bubbles forming, prick them down with a fork, and continue baking. You don’t want to impart color or have it turn golden. You just want it to firm up and hold together because the pan is going back into the oven anyway to bake the filling.
While the crust bakes, make the filling by coming two eggs, sugar, one-half cup of lemon juice, splash of cream, optional vanilla and lemon extracts, and whisk. My recipe differs from many I’ve seen in that it doesn’t use half of a carton of eggs, just two. The presence of two tablespoons of cream helps give the filling some depth, richness, and creaminess that you can’t get without it. Pour the filling mixture over the crust and bake it for 15 to 20 minutes, or until the top has just set. As you pour the filling over the crust, it will seem like it’s liquid soup and there’s no way that it will set up in 15 minutes time, but surprisingly, it does. Bake until the top has just set in the center and isn’t watery. Some movement and looseness is fine, and that’s how lemon bars are, but there shouldn’t be pooled liquid. Don’t overcook them and turn them into a rubbery state, either. They do firm up as they cool. Cool them for about 1 hour at room temperature, and then refrigerate them for at least 3 hours before slicing. Although you could serve them at room temperature, a chilled lemon bar with a dusting of confectioners’ sugar is the only way for me. They’ll keep for up to 5 days in the refrigerator in an airtight container.
Can I Double This Recipe?
Yes, simply double the ingredients and bake the lemon bars in a 9×13-inch pan. You may need to bake them for a little longer than the recipe calls for.
How to Store Lemon Bars
These homemade lemon bars will stay fresh up to 5 days in the fridge.
Tips for Making the Best Ever Lemon Bars
With lemon desserts, balancing tartness with sweetness can be tricky. Too much lemon, and I want to pucker up and hide; too little, and I’m bored. Too much sugar and they have a sickeningly sweet quality; too little, and I want the torture to end. I think these homemade lemon bars are spot on, both in tartness and sweetness. Of course, if you don’t want something quite as tart, you could start with 1/4 cup of lemon juice; taste, and increase accordingly. When zesting a lemon, make sure to just take off the outermost yellow layer. As you move into white pith, it becomes more and more bitter. There’s a difference between tartness and bitterness. I prefer the former, not so much the later. I didn’t need to add any lemon extract to these classic lemon bars as they’re already very lemony, but if you’re a lemon fiend, go for it. Citric acid will also make the lemon flavor really pop if you’re someone who just can’t get enough lemon intensity. It’s frequently used in pickling and canning, and found in the canning section of most grocery stores if you want to play around.
