Hi, my name is Dorothy and I have a gooey bar addiction.

I have about 3,453 versions on this site. Chocolate, Funfetti, Peanut Butter, Pumpkin, and the list goes on. Okay, so not quite 3,453…but if you could see inside my head, you’d know I wasn’t exaggerating…much. (Check out all my gooey bar recipes here!)

They are my favorite bar for so many reasons:

1. They’re so easy to make. Cake mix, butter, egg, and sweetened condensed milk. DONE.

2. They’re infallible. Pretty much you can’t mess these up, I promise.

3. They taste amazing. Like cake…but gooey and bar-like.

4. There are so many different flavor combos it’s mind boggling.

Maybe I should change my name to Crazy for Gooey Bars.

Right now? I’m crazy for lemon gooey bars.

I first made these last June for my sister-in-law’s birthday. She looooooves lemon. I always make her some sort of lemon dessert for holidays and celebrations.

I broke the food blogger cardinal rule last June when I made them: I didn’t photograph them. It was a last minute bake and there was no time to cut and take pictures.

(There is only one hard and fast rule about gooey bars: they need to chill and set before you cut them. I KNOW. It’s hard, but if you want pretty bars, you gotta do it. Or, just attack the warm pan with a fork. Whatevs.)

I finally re-made them at Christmas. I made a lot of things at Christmas and when asked what her favorite was, my SIL said “THOSE LEMON BARS!”

I figured it was time to share!

Okay, so let’s rundown the gooey bar in case you’ve never made them.

  • Cake mix + egg + butter forms a thick dough. Don’t use the box directions. Just use the cake mix powder and follow my directions.
  • Press about 2/3 of the batter into a pan. You don’t have to use foil, but I highly recommend it for this recipe. Sweetened condensed milk is sticky. Spray it well with cooking spray.
  • Add whatever mix-ins you like. White chocolate + lemon is amazing, but coconut would also be fab in these.
  • You break up the remaining chunks of dough and place it on top of the bars. I like to break off about 1/2-1 tablespoon size pieces and drop them over the top, then lightly press with my hands. Some of the SCM will show through.

Once they’re baked, cool and chill to set, then cut into bars. These freeze well, as long as they are in a single layer. They’ll stick to each other and whatever you put in between the layers.

But if you have any left to freeze I kind of don’t understand you. How is that even possible? Are you related to my husband?

Serving Size


  • 1 box lemon cake mix
  • 1/2 cup butter 1 stick, softened
  • 1 egg
  • 1/2 cup sweetened condensed milk
  • 1 cup white chocolate chips

  1. I think I’m going to add chopped candied lemon peel to these Lemon Gooey bars & & add creme de coconut to the sweetened condensed milk before drizzling it over the candied lemon peels… Lemon & Coconut YUM!

  2. Hi Dorothy,
    Have you done anything with a Spice Cake Mix? If so, could you elaborate? If not, any fabulous suggestions from that gooey brain of yours? LOL

    1. I haven’t but that’s such a great idea, it’s going on my list. You can totally use spice mix…might be good with apples in the middle, or caramel bits or Rolos!

  3. I just finished cutting and storing this delicious lemon bar when a local native bird flew into my kitchen, landed on the foil and started eating the leftover crumbs!!  This recipe has now been fully endorsed by the local Australian wildlife. I even have a photo to prove it. 

  4. I had these open on a tab on my iPad all week last week so I wouldn’t forget that I wanted to try them. Finally yesterday (Saturday) afternoon I found the time. They did not disappoint!  For me lemon and gooey go hand in hand an wow these are amazing. I had to cut them into tiny squares to make sure my kids didn’t gobble them all in one sitting :). Thanks so much, next we are trying slow cooker brownie pudding. 

  5. Hi Dorothy, what would you add to “lemon up” a golden cake mix? Specific measurements would be so helpful!  Thanks! 

    1. It depends on the recipe you’re making. I’ve found that lemon juice alone doesn’t really add lemon flavor to baked goods. It’s great for adding to frosting in place of (or in addition to) milk, but in baked goods your best bet is using lemon zest. For a cake, you could also add lemon extract and/or instant lemon pudding mix. For a regular cake mix making a regular cake, I’d add the zest of at least 2 lemons, 1-2 tablespoons of juice (you could use 1/4 cup juice and reduce the water/milk by that much). Then I’d also add either 1/2-1 teaspoon of lemon extract or one box (3.4 oz size) of instant lemon pudding mix.

  6. I have been meaning to comment for weeks; I made these bars for an Easter brunch and I cannot tell you all the compliments they received!  You have some new fans!  Great recipe Dorothy!

  7. These sound delicious! I’m going to make them for a bake sale on Friday. Did you use salted or unsalted butter? Do you think it makes a difference? Thank you!

    1. For these, you can use either interchangeably. I think I used salted, but I’ve made other gooey bars since with unsalted and no added salt, so either one works!
