Wait! These lemon bars are like the key lime pie?

They might remind you of the key lime pie preparation style, and you are not mistaken. This recipe is made with condensed milk, and it is creamy and heavenly delicious.

Very lemony and sweet enough to calm down a sweet tooth, these bars are easy to make and perfect for a party, a potluck, or just because you want to bake something extraordinary.

This recipe comes from my new friend Cristina, who sent me this recipe by email recently. She made the recipe for a party where she was in charge of bringing some dessert. 

Cristina lives in Spain and loves to bake. She was so sweet to send me a bunch of recipes that I am super excited to try. 

These lemon bars are baked in a square pan, so you can cut them in small servings, eliminating the guilt of overeating.

When life gives you lemons, there is so much more you can do than just making lemonade!

There is lemon cake, lemon cookies, lemon curd, lemon pie, lemon chicken and also lemon bread.

The possibilities are endless and all delicious.

What goes into this dessert:

  • Graham crackers – or digestive biscuits if you live outside of United States.
  • Unsalted butter– melted 
  • Egg yolks 
  • Lemons- the lemons can be swaped for limes, key limes, oranges or any other citrics you might like
  • Cans of condensed milk  
  • Heavy cream 
  • Granulated sugar

How To Make These Easy Lemon Squares:

The perfect lemon bar recipe needs only two things to be delicious: the right amount of lemon and the right amount of butter in the crust. 

Too little lemon and the bars are boring, too much lemon and they become inedible.

The nice part about this recipe is that you can substitute lemons with limes, key limes, or any other favorite citrus.

Now, you know that if you change the recipe and start replacing ingredients, the taste will be different, right?

For example, if you add orange juice instead of lemon (because you want the recipe, but you forgot to buy lemons when you went shopping), the bars will be sweeter with less zing, as oranges have more sugar.

They are not the same, even if they are all called citrus, so keep that in mind if you start experimenting. (I am looking at you, the ones who usually do not follow instructions and start messing with the recipes!) 🙂

The Crust:

  • Using a food processor(affiliate link), the process is fast, as you just put the graham crackers and the butter in the food processor and pulse a few times to obtain a wet sandy mixture.

Note: If you feel frustrated because you don’t have a food processor, which I encourage you to buy (it is a true lifesaver in the kitchen), grab a sturdy plastic bag and place the crackers inside.

  • Seal the bag and grab that rolling pin. (You know, the one that you were wondering what is doing in your kitchen, as you never used it before.)  

Smack the life out of the crackers until you have fine crumbs. 

  • Put the crumbs in a bowl, add melted butter and mix well with a spoon until you have a wet sandy mess. Then, continue with the recipe.

  • Press the crumbs into the pan and bake for about 10 minutes. Let the crust cool, but leave the oven on. We are going to bake the dessert again.

Make the filling.

This part of the recipe looks like a chemistry experiment that is fun to do. We have to mix egg yolks with lemon juice and condensed milk.

The mixture is actually the base for the key lime pie. It could be that the inspiration for this recipe comes from the way the pie is made.

When you mix these three ingredients, a chemical reaction happens between the protein in the egg yolks, condensed milk, and the acidic lemon juice that allows the mixture to become thicker on its own.

In the past, the recipes that used this combination of ingredients did not require baking.

However, today, we all know that consuming raw eggs can be dangerous, so desserts of this nature are usually baked for a short time, enough to make the eggs safe to eat.

The baking also thickens the dessert a little bit more, which makes it better for transportation.

  • Separate the eggs. So, to make the filling, we start separating the eggs. The recipe for the filling requires egg yolks that we will mix with the lemon zest.

A hand mixer(affiliate link) would be good because the speed helps thicken the filling.

  • Pour the condensed milk in a steady stream mixing constantly.

I used this excellent tool (affiliate link) to squeeze lemons, and it works for different citrus fruits sizes.

  • Squeeze the lemons, then add the juice and mix again. You will notice that the filling is getting thicker by the minute.
  • Pour the filling over the crust and return the pan to the oven to bake for another 12-15 minutes.

I say 12-15 minutes because it depends on how sturdy that filling you want it to be.

I baked it for 15 minutes and liked the texture. If you bake it less, it will be softer, which might not be ideal when you try to cut it, but I saw some recipes saying that the filling should be slightly set—your choice.

It will get set a little bit more when you refrigerate it for at least 4 hours.

Before doing that, beat some heavy cream with a little sugar and spread it over the lemon filling. Decorate with lemon peel or thin slices of lemon. 

Serve cold.
