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

She LOVED lemon desserts.

The end.

Gooey Lemon Cake Bars: easy lemon bar recipe using a cake mix and a cheesecake topping. EASY 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.

  6. Love lemon desserts! And nothing wrong with using a cake mix! A girl can’t do it all!

  7. Is it weird that I do a little dance everytime you post a lemon recipe? Love lemon, need this in my life 🙂

  8. The fact that you put gooey in the title makes me want to make (and eat!) these immediately. They look sooo good!

  9. Lemon treats are on my list too – this one looks awesome! I love how easy it is 🙂

  10. I think you got the number of servings wrong – you added a 6 when it should really just say 1 😉

    I’m confused about this recipe, I pour the cream cheese icing on top BEFORE baking?
    thank you

  17. I don’t use a mix often, but back off. It’s summer. <– LOL I can hear the comments now 🙂 I have a cookie recipe next week that's nobake. It's summer, who cares 🙂

    And gooey cake is the best kind of cake!

    MMM….I love lemon!

  19. There once was a good blogger friend named Jocelyn who loved desserts made from cake mixes.

    I heart easy breazy desserts that start from a mix, but you knew that already 🙂 I heart this fun and delicious cake!!!

  20. I could eat an entire plate of these! They look so ooey gooey and lovelyyyy 😀

  21. This is the absolute perfect, easy dessert for summer! Pinned!!

  22. I’ve got that same lemon love affair! Love this simple recipe and of course, love your presentation and photos!

  23. Oh these bars look heavenly Aimee! Anything with lemon is just perfection in my book 🙂

  24. Love lemon desserts! These bars are amazing! Nothing wrong with taking shortcuts here and there!

  25. YAY more lemon! Tis the season and cake bars are amazing! Especially when they are gooey and smothered in frosting!

  26. Pinned this before I even read the post, they look that good!! Who cares if it’s a cake mix, it’s lemon deliciousness!!

  27. These look so good! I love the creamy top layer. I’ve made gooey butter cake with yellow cake mix but never thought to make it lemony!

  28. Sounds delicious, but I think I will try using lemon juice instead of vanilla. What do you think?

  29. I love lemon, too. We just bought a baby lemon tree, and I’m really hoping we can keep it alive. How awesome would it be to just walk into your backyard and get a lemon? I’m definitely trying this recipe.

  30. I love lemon bars! These look fantastic and I love how simple they are!

  31. I love lemon bars 🙂 this looks fantastic!

  32. LOVE lemon bars; these look so yummy! Beautiful pics Aimee!

  33. Rebekah

    Are you supposed to bake these bars with the cream cheese topping on them? Or do you put it on after? The instructions say to bake it with the topping but the picture looks like you put it on after baking.

  34. Oh I love me some lemon, too, Aimee! These look awesome.

  35. angie

    Can I use lemon extract instead of vanilla or will it overwhelm it?

    Mine did not turn out like picture at all!!! Crust was all brown…top was okay but certainly not as light and yummy looking as yours. I used the same cake mix…not a fan.

  38. I made this today, and mine looks nothing like yours. I am so bummed. It’s such a simple recipe, I thought for sure it would be fail-proof. Sad day 🙁 Does it need to bake at a lower temperature? My edges were pretty brown, but my cake crust was dense and lost all it’s pretty yellow color. It tasted like cheesecake with a little lemon. I so wanted it to look and taste like yours 🙁 I made some strawberry sauce & topped it with that. It redeemed it a little. Just can’t seem to figure out where I went wrong.

    • Amber, bummer! I make gooey cake bars all the time with this recipe, swapping out different cake mixes for the base flavor. I honestly don’t know what could have gone wrong?! Mine definitely has a lot of lemon flavor, and stayed quite yellow (clearly 🙂 The only things I can think of would be is to check your oven temperature? Although, I know with all your baking it’s bound to be close to accurate! Sorry I have no other help for you 🙁

    I have made these twice now. The first time I added some extra lemon just and some zest to the cream cheese topping and I got rave reviews. This time I just left it per your instructions. I am sure they will be great either way! Thanks so much for the great recipe!

    Can these bars be frozen?

    Do you have to use a “cake mix”? I like making food from scratch.

  44. Kate

    Mine turned out dense and not light or fluffy like the picture. I’m thinking I baked it too long. And, I baked mine using my convection oven. Next batch will be with the regular oven and I will watch the time. Also, my topping never got what I would call light and fluffy, so I will make sure the eggs are at room temp along with very soft cream cheese. I think the recipe is super easy, but the little things matter a lot if you want the perfect result. Thanks!

  47. I just shared this recipe on my “Weekly Round-up” series of top recipe finds! This week was all about lemons, so I knew this was a must add. Thank you for sharing such a wonderful recipe with us!

    Recipe for the frosting on these lemon bars. Didn’t see it anywhere and would love it to finish them like yours. Yummy! Thanks.

    Very disappointed. They were neither gooey nor lemony. In addition to the fact that the recipe does not give different baking times for glass and metal pans, I nearly burned out the motor of my small, hand held mixer beating the dough, But let’s get to what’s advertised. Perhaps living in Costa Rica where lemon flavors everything, I found simply using the cake mix fairly bland and with no additives with lemon in the topping, there was no addition zing.
    Adapting the first time, I added 1/4 cup of lemon juice to the batter making a somewhat crumbly base (I’d adjusted cooking time as well) and added the zest of three limes to the topping. It still didn’tr reach the desired intensity. On my final try, I layered in a strong glaize of homemade lemon on top of the cake then added the zest of five limes to the topping and when serving added a combination of lime and lemon zest for color and flavor.

    My RANT of the year… All these wonderful recipes that use Duncan Hines cake mixes that call for 18.5 oz. that are now 16.5 and even 15.25 (Betty Crocker, which isn’t as tasty as Duncan Hines). . I have an AMAZING Earth Quake Cake that I’ve made over the years, Lemon Blossoms that are to die for… and POOF! The ratio is off. I’d rather pay more for the cake mixes then have the 1% companies make us believe we’re getting the same amount for the same price. Ok… hopping off my soap box. I’m still going to try this recipe with the 15.5 oz box.

    is the butter and eggs for the crust seprate, (like extra from the eggs and milk the box says to add) or is it part of the cake mix ingredients?

  53. Jess

    I only have a 16.50 oz box…do I need to change the recipe to account for the difference?
