A delicious lemon bar with a flaky buttery crust, in style of a shortbread cookie. A tart lemony filling, with the right amount of sweet and tart. I made this recipe up after years and years of trying to find the perfect lemon bar, and believe this to be the best. I hope you enjoy with your favorite cup of tea or coffee!

Instructions Checklist
  • Preheat oven to 350 degrees F (175 degrees C). Line a 7 x 11-inch baking pan with foil; spray with cooking spray.

  • Combine flour, 1/4 cup cornstarch, 1/4 cup powdered sugar, and white sugar in a bowl. Mix in the butter; and stir until well mixed and crumbly. Press mixture in bottom of prepared pan.

  • Bake in preheated oven until lightly golden, about 15 minutes.

  • Mix 3/4 cup white sugar, eggs, 2 tablespoons cornstarch, baking powder, lemon juice and lemon zest together in a mixing bowl using an electric mixer or wire whisk. Blend thoroughly.

  • Pour filling over hot crust. Return pan to oven and continue baking until filling is set, 18 to 20 minutes.

  • Cool completely before cutting into bars. Sprinkle with powdered sugar if desired.

Cook's Note:

The filling is made with cornstarch, not the typical added flour. Since I use cornstarch with my fresh berry pies, I thought let's give it a try! We have a lemon tree in our back yard so I had plenty of lemons to perfect this recipe. Also with the Land O' Lakes(R) butter campaign I wanted to make this the best buttery crust!

I followed the recipe as written without changes. I was skeptical because I'm known for making great lemon bars, but I liked seeing methods different from my own and thought it would be fun to give these a try. First, I would like to note that I have hens and used very fresh eggs. Also, I had organic lemons that I used. I don't know if that would make a difference for others in taste. Also, Land O Lakes butter is an excellent butter to use while baking. I used a coconut oil non stick spray. Despite the recipe totally being different from my own, they were almost as good as my recipe (I HAVE to say that, right?). I personally like to have a 50/50 ratio with lemon bars regarding the cookie versus the lemon filling because the cookie part is just as important in my life. I give these five stars for taste and because it was great using every day ingredients I had in my house (yes, I had a bag of lemons). I really enjoyed them. Read More

These were ok. The ratio of crust to lemon filling, IMO is off. I made it in a 7" x 11" pan as called for in the recipe and the crust was as thick as the filling. I also prefer a bar with more lemon as I found these to be more sweeter than lemony tasting. Read More

Very tasty and I even made it gluten free. My first time making lemon bars and they are the best that I have ever had. I gave them to my parents and they loved them as well. I would recommend these to a friend. Read More

No changes I would give it 10 stars!! Not overly sweet or tart crisp crust. Hardest part was jesting the lemon. I Love it. Read More
