Let’s be honest. Sometimes you don’t want a dessert that challenges you. You don’t want a geometric pastry that requires a degree in architecture to construct, and you certainly don’t want a fruit salad masquerading as a treat. Sometimes, you just want pure, unadulterated sugar and fat. Enter the Gooey Butter Cake Bar. 🧈
If you grew up in St. Louis, you know exactly what I’m talking about. If you didn’t, prepare to have your life changed. This isn’t really a cake, and it isn’t really a cookie. It is a dense, chewy, buttery slab of happiness that defies categorization.
I distinctly remember the first time I tried to explain this dessert to a health-conscious friend. I listed the ingredients: butter, cream cheese, powdered sugar, and cake mix. She looked at me like I had just confessed to a crime. But then she took a bite. Five minutes later, she was asking for the recipe.
These bars are the culinary equivalent of a warm hug from your grandma—if your grandma didn’t care about your cholesterol. They are sticky, sweet, and arguably the most addictive thing you will ever bake. Let’s dive into the glorious mess.
What on Earth is a Gooey Butter Cake?
You might wonder, “Is it actually gooey?” Yes. If it’s not gooey, you did it wrong.
Legend says a German baker in St. Louis made a mistake in the 1930s. He mixed up his butter proportions for a coffee cake, creating a dense, under-baked sludge instead of a fluffy loaf. Instead of throwing it out (because waste is a sin), he sold it by the square. It sold out immediately.
The modern “bar” version simplifies that original yeast-based recipe. We create a two-layer masterpiece:
- The Crust: A sturdy, chewy base made from yellow cake mix.
- The Goo: A velvety, cream cheese-based custard that sits on top.
When you bake them, the top creates a crackly, paper-thin crust, while the center stays molten and rich. It’s a texture contrast that hits every pleasure center in the brain. 🧠
The Great Cake Mix Debate
I need to address the elephant in the room. This recipe uses boxed cake mix.
I know, I know. You’re a serious baker. You make your own sourdough starter. You own a scale. But listen to me: Do not try to make this from scratch.
I have tried the “gourmet” scratch versions. They are fine. But they lack that specific, nostalgic flavor profile that only a box of yellow cake mix can provide. There is something about the chemical magic in that box that creates the perfect chewiness for the base.
Sometimes, convenience wins. Put your pride aside, buy the yellow box, and thank me later. FYI, nobody will know the difference once they are in a sugar coma. 🍰
The Grocery List (Don’t Skimp!)
You need distinct ingredients for the two layers. This is not the time for “low fat” substitutions. If you use low-fat cream cheese, the filling will turn watery and sad.
For the Crust (The Base)
- 1 Box (15.25 oz) Yellow Cake Mix: Duncan Hines or Betty Crocker work perfectly.
- 1/2 Cup (1 Stick) Unsalted Butter: Melted.
- 1 Large Egg: Room temperature.
For the Goo (The Filling)
- 1 Block (8 oz) Full-Fat Cream Cheese: Crucial: It must be softened to room temperature.
- 2 Large Eggs: Also room temperature.
- 1 Teaspoon Pure Vanilla Extract: Don’t use the fake stuff.
- 1/2 Cup (1 Stick) Unsalted Butter: Melted.
- 3 3/4 Cups Powdered Sugar (Confectioners’ Sugar): Sift it if it’s lumpy.
- Extra Powdered Sugar: For dusting the top.
Step 1: The Crust Construction
Preheat your oven to 350°F (175°C). Spray a 9×13 inch baking pan with non-stick spray.
Grab a large bowl. Dump in the cake mix, the 1/2 cup melted butter, and the 1 egg.
Mix this together. I usually ditch the spoon and use my hands (clean ones, obviously). It will form a thick, stiff dough. It feels a bit like Play-Doh.
Take the dough and dump it into your greased pan.
The Press: Use your palms to press the dough evenly across the bottom of the pan. It might feel like you don’t have enough dough, but just keep spreading. It’s a thin layer, but it puffs up.
Pro Tip: If the dough sticks to your hands, lightly dust your fingers with flour or powdered sugar. It makes the pressing process much less annoying. 🖐️
Step 2: The Goo Assembly
Wipe out your bowl (or grab a new one).
Place the softened cream cheese in the bowl. Use a hand mixer or stand mixer to beat it until it is perfectly smooth.
Warning: If you skip this step or use cold cream cheese, you will get little white lumps in your filling. Those lumps do not melt. They stay there, judging you. Beat the cheese until it looks like lotion.
Add the 2 eggs and vanilla. Beat again until combined.
Slowly pour in the 1/2 cup melted butter. Mix until incorporated.
Now, turn the mixer to low speed. Gradually add the 3 3/4 cups powdered sugar.
Once the sugar is wet, crank the speed up for 30 seconds. You want a smooth, thick batter that looks like cheesecake filling.
Pour this glorious mixture directly over your crust in the pan. Use a spatula to spread it to the corners.
Step 3: The Bake (The Wiggle Test)
Slide the pan into the oven.
Bake for 35–40 minutes.
This is the hardest part of the recipe: Knowing when to take it out.
You do not want the center to be firm. If you bake it until it’s solid, you just made a dry yellow cake. We want gooey.
The Wiggle Test: Open the oven and gently shake the pan. The edges should look golden brown and set (like a brownie), but the center should still jiggle like Jell-O.
Trust the carry-over cooking. The heat trapped in the pan will finish setting the center as it cools. Take it out while it still looks a little underdone. 🔥
Step 4: The Cool Down
Place the pan on a wire rack.
Do not touch it. Do not cut it. You must let it cool completely.
If you cut into it while it’s hot, the filling will run out like lava, and the bars will fall apart. It needs at least 2 hours to set up properly.
Once it reaches room temperature, sprinkle a generous dusting of powdered sugar over the top. This hides the cracks (there will be cracks, and that’s okay) and makes it look pretty.
Cut into squares. I suggest small squares because these things are rich. You can always eat two, but starting small makes you feel better about your life choices.
Troubleshooting: Why Is My Cake Sad?
Did things go sideways? Let’s diagnose the issue so you can fix it next time.
- The Filling is Runny: You underbaked it too much, or you cut it while it was hot. Alternatively, you used low-fat cream cheese (shame on you). Put it in the fridge; the cold will firm it up.
- The Crust is Hard: You overmixed the base or baked it too long. Next time, treat the base dough gently.
- There are Lumps in the Goo: Your cream cheese was cold. I warned you! Next time, leave the cheese on the counter for an hour before starting.
- It Sunk in the Middle: This is actually normal! As the goo cools, it often collapses slightly. That’s why we call it “Gooey Butter Cake” and not “Perfect Soufflé.” The sunken center just holds more powdered sugar.
Variations to Spice Things Up
Once you master the classic St. Louis style, you can start getting creative. The formula (Cake Mix + Cream Cheese) works with almost any flavor profile.
The Lemon Burst 🍋
- Crust: Use a Lemon Cake Mix.
- Goo: Add 2 tablespoons of fresh lemon juice and 1 tablespoon of zest to the cream cheese mixture.
- Result: A bright, sunny bar that tastes like a lemon bar and a cheesecake had a baby.
The Pumpkin Spice (Basic but Delicious) 🎃
- Crust: Use a Spice Cake Mix.
- Goo: Add 1/2 cup pumpkin puree and 1 teaspoon pumpkin pie spice to the filling.
- Result: The ultimate Thanksgiving dessert that requires zero pie crust effort.
The Chocolate Overload 🍫
- Crust: Use a Devil’s Food Cake Mix.
- Goo: Stir 1/2 cup melted chocolate chips into the cream cheese mixture.
- Result: A brownie on steroids.
Storage: The Fridge Factor
These bars live a double life depending on how you store them.
- Room Temperature: If you leave them on the counter (covered tightly), they stay soft and incredibly gooey. They last about 3 days.
- The Fridge: IMO, this is the superior method. Chilling the bars turns the filling into a dense, fudge-like consistency. It makes them chewier and less messy to eat. They last up to 1 week in the fridge.
- Freezing: Yes, they freeze! Cut them, wrap them in plastic, and freeze for 3 months. Eating a frozen Gooey Butter Bar is an experience I highly recommend.
Nutritional Information (Per Serving)
I’m going to level with you. You shouldn’t look at this. Just close your eyes and enjoy the cake. But, since I promised to be informative, here is the damage.
Estimates based on cutting the pan into 24 squares:

Note: If you cut the pan into 12 “generous” slices, double everything. Proceed with caution.
Conclusion
Gooey Butter Cake Bars represent everything right with home baking. They are unpretentious, messy, and unapologetically rich.
They remind us that not every dessert needs to be a delicate French pastry. Sometimes, the best things in life come from a box mix and a brick of cream cheese.
So, next time you need to bring a dessert to a potluck and you want to be the hero of the party, make these. Watch people take that first bite, pause, and then reach for a second piece. It happens every time.
