My little chef-in-training, Tyler, was given his own apron and kids cookbook for Christmas. We’ve tried a few of the recipes from it so far, including a recipe for Lemon Bars that was absolutely delicious!

I usually am not a fan of lemon-based desserts, but I couldn’t get enough of these lemon bars! I can’t believe how simple they are to make, and of course, the boys loved to help with this recipe. According to Tyler, he had to help since it was from his recipe book!

Last week, Tyler asked if we could make something from his cookbook, and he wanted to make a dessert. So we looked through the book and found this recipe. He gets so excited to help in the kitchen. He immediately runs to grab his stool, wash his hands, and asks for help putting his apron on. Now and then, Ryan decides he wants to help as well.

One of the best aspects of this recipe is the ingredient list. Everything required to make the lemon bars are foods I almost always have on hand. The only thing I don’t always have is a lemon, but the zest is just extra. And I do make sure to have lemon juice in the refrigerator at all times.

Kid-Friendly Lemon Bar Dessert Step by Step



  • 12 tbsp butter (softened)
  • 1 1/2 cups all-purpose flour
  • 1/3 cup powdered sugar


  • 4 egg whites
  • 1 1/4 cups granulated sugar
  • 1 1/2 tbsp lemon zest
  • 1/2 cup lemon juice
  • 1/2 tsp vanilla extract
  • 1/3 cup all-purpose flour



Start the recipe by making the crust. Use a mixer to blend 3/4 cup of butter until it becomes fluffy, usually about a minute. You can use a hand-held electric mixer or a stand mixer if you have one.

Then add the flour and powdered sugar, mixing until it forms a soft dough.

Bake the crust for about 15-20 minutes or until the edges just start to brown. Take it out of the oven and let it cool completely before moving on to the filling.


Meanwhile, use a mixer to combine the egg and sugar. Then add the lemon zest, lemon juice, and vanilla extract.

Blend in the flour until it is all combined, scraping the edges as needed.

Once the crust is cool, pour the filling into the pan over the crust. Tilt the pan around to make sure the filling covers the crust.

Bake the lemon bars for about 25 minutes. The filling needs to be completely set. After 25 minutes, I used an oven mitt and gave the pan a slight shake. The filling wiggled a little too much, so I left it in for another 5 minutes. After the filling has cooled, cut the bars into small pieces and dust with a bit of powdered sugar.

Storage: The lemon bar leftovers should be stored in an airtight container. We like to keep them in the refrigerator since it’s so humid where we live.

    I love all things lemon and this is definitely one of my favorite ways to have it! Your recipe is different from mine though so I am totally going to have to try it and see which I like better! Love that your let your kids pick and help!

    1. I’d be interested to hear what the difference is! This came from a kids recipe book, so it’s supposed to be something they can easily do and enjoy. And these boys love to be in the kitchen, especially my oldest son!

  2. 5 stars
    It’s great when kids can learn skills and have fun making things. They are adorable, and these lemon bars look amazing! They’d be gone in two seconds in my house!

    1. Even before I knew how much they loved helping in the kitchen, I always said I would make sure to teach them at least the basics of the kitchen so they can feed themselves when they are older! And these lemon bars did not last long here either!!

  3. 5 stars
    The kids did a great job! I’m sure it was a real confidence booster to see you wolf down a lemon-based dessert you wouldn’t normally eat! Teaching kids to cook from a young age is so important. Not only is it an invaluable skill in itself, but it also teaches them to follow directions.

  4. Oooo how delicious!!!! Lemon is a favorite of mine! Especially this time of year. Definitely need to make these lemon bars with my daughter!!

  5. Lemon bars are my favorite dessert! I can’t get enough of the tanginess! It’s awesome that he loves to help you in the kitchen too. I hope when I have kids, they’ll want to help me!

    1. We started them in the kitchen from a young age. First, it was just pouring and a bit of mixing but we’ve started letting my oldest son even use a knife a few times now!

  6. 5 stars
    I am going to have to make these with my daughter whether she ends up liking them or not. I love lemon bars and I love trying to make things with my daughter. This would be fun, and at least I’d enjoy the fruits of our labor. She’d just have fun doing it. 🙂
