White Chocolate Lemon Cookie Bars Recipe

I actually made them for my grandmother. She is a BIG lemon fan. She’s also a big white chocolate fan. I know I’m her granddaughter because we have a love of white chocolate in common. On any given day, we’d both choose a block of white chocolate over the others.

The last couple years, my thing has been to give her something edible for Christmas. It’s usually a combination of something I made and something fun that I buy.

Last year, we got to see her a couple weeks before Christmas on our way to a wedding. I’d made my triple lemon cake for my mom’s birthday and everyone raved about it. She was bummed she hadn’t gotten to have any, so I brought her her own personal lemon cake. She loved it.

When I started to think about what to make her this year, I had to keep in mind that I sadly wasn’t going to get to deliver it in person. So it needed to be something that would ship well and still be moist and delicious after 2-3 days.

I immediately thought of my Gingerbread Caramel Gooey Bars. Did you make them? They are one of my favorites! And they stay moist and chewy for so long, I knew they were perfect. Making them lemon and white chocolate was the obvious choice.

How to Make White Chocolate Lemon Bars

One of the great things about this recipe is how easy it is. It starts with a cake mix. Add to that some butter, an egg, sugar and milk and mix it up and your dough is ready to go!

After pressing a little more than 1/2 of the dough into a 9×9 pan, you add a layer of white chocolate chips and some sweetened condensed milk, then top with the remaining dough. Bake it up and you’re good to go! How easy is that?

When my grandmother got these in the mail, she literally couldn’t wait to eat them and immediately dove in! Winner! She loved them too. 🙂

I definitely have the coolest grandmother ever. I feel like not everyone gets to have great relationships with their grandparents, but I’m so fortunate to have such an awesome one with her. She is a fabulous dance partner, a wonderful friend and has an amazing strength that I admire very much. She’s kind of like a second mom.

I’m so glad she loved her bars and I hope you love them too! Certainly if you are a lemon fan, these bars should be at the top of your “must bake” list!

These Lemon White Chocolate Gooey Bars are the jam. They’re super moist, chewy, and full of lemon flavor! And they stay that way for days!


  • 15.25 oz lemon cake mix
  • 1/2 cup butter, softened
  • 1 egg
  • 1/2 cup sugar
  • 1/4 cup milk
  • 1 cup white chocolate chips
  • 1/2 cup sweetened condensed milk


1. Combine cake mix, butter, egg, sugar and milk in a bowl and mix until smooth. Batter will be thick.
2. Line the bottom and sides of a 9×9 pan with parchment paper.
3. Add a little more than half of the batter to the bottom of the pan and spread evenly. Because the batter is thick, it might help to drop spoonfuls into the pan, then spread.
4. Add the white chocolate chips in an even layer on top of the batter.
5. Pour the sweetened condensed milk in an even layer on top of the white chocolate chips.
6. Drop spoonfuls of the remaining dough on top the sweetened condensed milk, spreading it a bit to mostly cover the other layers.
7. Bake at 350 degrees for 30 minutes.
8. Allow to cool in the pan, then cut into squares. Bars should be good stored in an airtight container for 7-10 days.

    First, I want to say this recipe is amazing! Taste and texture are out of this world! But I wanted to post that I tried to double the recipe and place in 9×13 pan, and that didn’t work very well. I have made a single batch and they turned out perfectly so I know what the finish product looks like. I used BC cake mix so both were 15oz boxes so not the larger box. They looked like they were going to flow over the sides! I baked for 35 minutes which I let set overnight to cool. They are very gooey but hold shape and appear baked on bottom so I don’t think I under baked them, but they are such different heights in the same pan. The sides were twice as high as the middle and just to note: use parchment! I have a very nice pan that nothing sticks…usually, but these did so many of them broke apart trying to get them out of the pan. So I posted in case someone else has the desire to double the recipe, place in 2- 9” pans or maybe try 1.5x recipe. Hope this helps!

    Just confirming that you only use a partial box of cake mix.  My Duncan Hines lemon cake mix weighs 18.5 oz,  According to your recipe, I should only use 15.25 oz,., so a partial box, yes?

      I think they have changed the size of box mixes since I made this recipe. I don’t think it’ll hurt the recipe though.

Such ooey gooey deliciousness. I’m gonna TRY and save some for the family but I could literally eat the whole yummy pan!! Thanks for sharing!

    These look amazing, I’m making them tonight for a food day at work tomorrow! If I want to double the recipe, is a 9×13 dish sufficient? Or should I do them in 2 9x9s?

    I made these and actually omitted the sugar that you add to the cake mix. They turned out SO unbelievably sweet and gummy. I cannot imagine adding even more sugar to them. I’m sorry, but these were a huge miss for me.
