The Origin of Gooey Butter Cake
Gooey Butter Cake originated in St. Louis, Missouri, back in the 1930s. It’s said to have been an accident — a baker mistakenly added too much sugar and butter to his cake batter, creating a wonderfully gooey texture that people couldn’t get enough of. Over time, this mistake turned into a beloved classic dessert, and today, it’s a staple in many Southern kitchens.
This version of gooey butter cake bars takes the original concept and adds a twist, making it even more delicious and indulgent. So, if you love classic desserts with a modern touch, this recipe is a must-try!
Ingredients for Secret Ingredient Gooey Butter Cake Bars

For the Crust:
- 1 box yellow cake mix (15.25 oz)
- ½ cup melted butter (115 g)
- 1 large egg
For the Gooey Filling:
- 8 oz cream cheese, softened (225 g)
- 1 cup sweetened condensed milk (the secret ingredient!)

- 2 cups powdered sugar

Step-by-Step Directions for Preparing Gooey Butter Cake Bars
Making Secret Ingredient Gooey Butter Cake Bars is simple and fun, with just a few steps to follow. Here’s how you can prepare these bars at home:
1: Prep the Oven and Pan
- Preheat your oven to 350°F (175°C).
- Line your 9×9 or 9×13 baking pan with parchment paper. This will help you easily remove the bars later and ensure even baking.
2: Make the Crust
- In a mixing bowl, combine the yellow cake mix, melted butter, and 1 egg. Mix until smooth.
- Press the dough evenly into the bottom of the prepared pan. The dough will be thick, similar to cookie dough, so don’t worry if it’s a bit hard to spread.
3: Make the Gooey Filling
- In a separate bowl, beat the cream cheese until smooth and creamy.
- Add the sweetened condensed milk, eggs, vanilla extract, and salt. Mix until smooth and silky.
- Gradually add the powdered sugar, mixing on low speed until everything is combined and the mixture is glossy.
- Pour the gooey filling mixture over the crust, spreading it evenly.
4: Bake the Bars
- If using a 9×9 pan, bake for 30–35 minutes.
- If using a 9×13 pan, bake for 25–28 minutes.
The bars are done when the edges are set and golden, but the center should still slightly jiggle. This is the key to getting that delicious gooey texture.
5: Cool and Slice
Let the bars cool completely before slicing. If you want cleaner slices, chill them in the fridge for about an hour. If you prefer a messier, gooier treat, go ahead and dig in while they’re still warm!
Variations of Secret Ingredient Gooey Butter Cake Bars
While the original recipe is already irresistible, there are many ways to customize it and add new flavors. Here are a few tasty variations:
1. Chocolate Gooey Butter Bars
Use a chocolate cake mix for the crust and add ½ cup chocolate chips to the gooey filling. This creates a decadent chocolate twist on the classic dessert.
2. Lemon Gooey Bars
For a refreshing citrus twist, use lemon cake mix and add lemon zest to the filling. These bars are perfect for spring and summer!
3. Coconut Cream Version
Add ½ cup shredded coconut to the gooey filling and a splash of coconut extract for a tropical flavor that will transport you to paradise.
4. Cookie Butter Gooey Bars
For a spiced, indulgent treat, add ½ cup melted Biscoff spread (cookie butter) to the filling. It gives the bars a deep, caramelized flavor that’s simply irresistible.
5. Pumpkin Gooey Bars
Perfect for fall, add ½ cup pumpkin purée and 1 tsp pumpkin spice to the filling. Reduce the sweetened condensed milk by 2 tbsp to balance the moisture, and you’ll have a fall-inspired version of gooey butter cake bars.
Tips for Perfecting Your Gooey Butter Cake Bars
Achieving that perfect gooey texture takes a bit of attention, but with these tips, you’ll master the recipe every time:
- Don’t overbake! The secret to gooey bars is that slightly jiggly center. Overbaking will make them dry, so check them at the lower end of the baking time.
- Beat the cream cheese well to ensure it’s completely smooth before adding other ingredients. This helps avoid lumps in the filling.
- If you want cleaner slices, chill the bars in the fridge for an hour before cutting them.
- Serve the bars with a dusting of powdered sugar, a dollop of whipped cream, or a scoop of vanilla ice cream for an extra touch of indulgence.
