Once upon a time there was a cute food blogger named Aimee.

She LOVED lemon desserts.

The end.

This post was previously published in May 2013. As I’m still a lover of all things lemon, I thought you’d all enjoy this updated version, complete with a food video too!

Seriously, there is not much else to say about this recipe. I am in love with all things lemon! These lemon bars are made simple by using a cake mix (gasp!!!). I know, I don’t use a mix often, but back off. It’s summer.

Almost summer. Which means absolutely nothing except I wanted an excuse as to why I used a mix. Oh yeah, I used a mix on this because that’s what the recipe calls for!

I based these lemon bars off of THIS cake recipe. By just changing it slightly they become a whole new dessert. You can make these even prettier by adding some fresh raspberries or strawberries on top as a garnish.

But they don’t need any help in making them tastier. These cake bars are divine. Try them yourself.

How to make Gooey Lemon Cake Bars:

  • Start with your favorite cake mix! I use Duncan Hines Lemon Cake mix….but choose YOUR favorite.
  • Add softened butter and egg to cake mix, and press this into the bottom of your 13×9 baking dish. This will create the crust.
  • Beat your filling until light and fluffy and spread it over the top of the cake mix crust. BAKE for about 30-35 minutes. Do not overcook.
  • Once you’ve removed the Lemon Bars from the oven, cool on wire rack. When cool, place bars in refrigerator for at least 4 hours (this is a must!!). Top with powdered sugar and enjoy cold!

  1. Looks delicious! We love anything lemon at my house.

    I took your advice, used my yellow cake mix, added the zest of one lemon and switched the vanilla extract out with lemon extract to the filling-the flavor was spot on. I’m afraid if I had added lemon to the cake mix, it might have been too much. Thank you for your suggestions!
