Some desserts get their name exactly right. Ooey Gooey Bars are precisely that: a buttery, slightly chewy cake mix base topped with a rich, creamy cream cheese layer that bakes until the edges turn golden and set while the center stays soft, dense, and irresistibly gooey. They come together with a shortcut, a box of cake mix, but taste like something far more involved.
These bars belong to the beloved family of “gooey butter cake” desserts, a style especially popular in St. Louis and across the Midwest, where a cake mix crust meets a cream cheese and powdered sugar filling for a dessert that’s part cake, part bar, part cheesecake. The recipe comes together with two simple layers, needs no mixer skills beyond basic beating, and bakes in well under an hour. This guide covers the complete recipe, the role of each ingredient, the details that keep the center perfectly gooey instead of undercooked or dry, and plenty of ideas for variations, storage, and serving.
What Are Ooey Gooey Bars?
Ooey Gooey Bars are a two-layer bar dessert built on a shortcut foundation: a cake mix base pressed into a pan, topped with a cream cheese and powdered sugar mixture that bakes into a dense, custard-like layer. The name describes exactly what to expect. The edges bake up firm and lightly golden, while the center stays soft, rich, and almost molten, somewhere between a bar cookie and a baked cheesecake.
This style of dessert has deep roots in Midwestern baking, particularly the gooey butter cake tradition of St. Louis, where a cake mix crust and a cream cheese topping became a beloved way to turn simple pantry ingredients into something special. This version keeps things approachable, using a boxed cake mix for the base and a straightforward cream cheese filling, so the results are consistent and easy for any home baker to achieve.

Ingredients You’ll Need
The ingredient list splits into two short layers, each with a clear purpose.
For the Base Layer
1 box (15.25 ounces) yellow cake mix. The cake mix is the shortcut that makes this recipe so simple. Yellow cake mix gives a classic, buttery flavor that works as a neutral base for the sweet cream cheese topping.
½ cup unsalted butter, melted. Butter binds the cake mix into a soft, pressable dough and adds richness to the base layer.
1 large egg. The egg helps hold the base together, giving it enough structure to support the topping without crumbling.
For the Gooey Topping
8 ounces cream cheese, softened. Cream cheese is the foundation of the topping, giving it a rich, slightly tangy flavor and that dense, custardy texture. It must be fully softened to beat smooth without lumps.
2 large eggs. Eggs give the topping its structure as it bakes, helping it set at the edges while staying soft in the center.
1 teaspoon vanilla extract. Vanilla rounds out the sweetness of the topping with a warm, familiar flavor.
3¾ cups powdered sugar. This is what gives the topping its signature sweetness and helps create that dense, gooey texture once baked. Powdered sugar dissolves smoothly into the cream cheese, unlike granulated sugar, which would leave a grainy texture.
Equipment
- A 9×13-inch baking dish
- Parchment paper, for easy removal
- Two large mixing bowls
- An electric mixer or a sturdy whisk
- A rubber spatula
- A toothpick or cake tester, for checking the edges
How to Make Ooey Gooey Bars, Step by Step
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish, or line it with parchment paper for the easiest removal and cleanest slices later.
Step 2: Make the Base Layer
In a large mixing bowl, combine the cake mix, melted butter, and egg. Stir until well mixed and a soft dough forms. Mix just until the ingredients come together, since overworking the base can make it tough rather than tender.
Press the dough evenly into the bottom of the prepared baking dish, using your fingers or the back of a spatula to create a smooth, even base layer that reaches all the way to the edges.
Step 3: Prepare the Gooey Topping
In another mixing bowl, beat the softened cream cheese until completely smooth, with no lumps remaining. Add the eggs one at a time, mixing well after each addition, followed by the vanilla extract.
Gradually add the powdered sugar, mixing until the mixture is smooth and creamy. Adding it gradually, rather than all at once, helps prevent a cloud of powdered sugar and ensures it incorporates evenly.
Step 4: Assemble the Bars
Pour the cream cheese mixture over the base layer, spreading it out evenly with a spatula so it reaches every corner of the pan.
Step 5: Bake
Bake in the preheated oven for 35 to 40 minutes. The edges should be golden brown and set, while the center remains slightly jiggly. This jiggly center is exactly what you want. It is what gives the bars their signature gooey texture once they cool and set.
Step 6: Cool and Slice
Allow the Ooey Gooey Bars to cool completely in the pan before slicing into squares. Cooling is an essential step, since it allows the gooey filling to set enough to slice cleanly. Cutting into them while warm will result in a soft, runny mess rather than neat squares.

Tips for the Best Ooey Gooey Bars
Soften the Cream Cheese Fully
Room-temperature cream cheese blends into a smooth topping. Cold cream cheese will leave lumps that never fully disappear, even with vigorous mixing.
Mix the Base Just Until Combined
Overworking the cake mix, butter, and egg can make the base dense and tough rather than tender. Stir only until a dough forms.
Add the Powdered Sugar Gradually
Adding all 3¾ cups at once can create a cloud of sugar and make it harder to mix in evenly. Add it in a few additions, mixing well between each.
Don’t Overbake
The center should still look slightly jiggly when you take the bars out of the oven. That soft center is what sets into the classic gooey texture as the bars cool. Overbaking will give you a firmer, more cake-like result.
Let the Bars Cool Completely
Patience here really matters. A fully cooled pan allows the filling to set enough to slice into neat squares, while a warm pan will give you a gooey mess rather than clean bars.
Line the Pan for Easy Removal
Parchment paper with a slight overhang lets you lift the entire slab out of the pan before slicing, which makes for neater cuts and easier cleanup.
Troubleshooting Common Problems
My Bars Are Too Runny to Slice
They likely need more cooling time. Refrigerate the pan for an hour or so if you need cleaner slices sooner, since the cold will help the filling firm up further.
My Bars Are Too Firm or Cake-Like
This usually means they were baked a little too long. Next time, take them out of the oven when the center still has a gentle jiggle, since they will continue to set as they cool.
My Topping Has Lumps
The cream cheese likely wasn’t fully softened before mixing. Let it sit out longer next time, or microwave it in short bursts to soften it before starting.
My Base Layer Is Too Thin or Too Thick in Spots
Take a little extra care pressing the dough evenly across the bottom of the pan, using your fingers or the flat bottom of a measuring cup to smooth it into a uniform layer.
My Bars Stuck to the Pan
Make sure to grease the pan well, or use parchment paper with enough overhang to lift the bars out cleanly once they’ve cooled.
Variations to Try
Chocolate Ooey Gooey Bars
Replace the yellow cake mix with chocolate cake mix for a rich, chocolatey twist. You can also add ½ cup of mini chocolate chips to the gooey topping for extra indulgence.
Peanut Butter Ooey Gooey Bars
Add ½ cup of creamy peanut butter to the cream cheese mixture before adding the powdered sugar for a nutty, rich flavor.
Lemon Ooey Gooey Bars
Replace the yellow cake mix with lemon cake mix and add 1 tablespoon of lemon zest to the gooey topping for a fresh, citrusy version.
Spice Cake Version
Use a spice cake mix for the base for a warm, cozy flavor that’s especially nice in fall and winter.
Red Velvet Version
Use a red velvet cake mix for a striking, colorful base that pairs beautifully with the classic cream cheese topping.
Strawberry Ooey Gooey Bars
Use a strawberry cake mix for a fruity, brightly colored variation that’s popular with kids.

Frequently Asked Questions
Can I make Ooey Gooey Bars ahead of time?
Yes. They can be made up to 2 days in advance and stored in an airtight container at room temperature or in the refrigerator.
How do I store leftovers?
In an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. They can also be frozen for up to 3 months.
Can I use a different cake mix?
Absolutely. Spice, red velvet, strawberry, chocolate, or lemon cake mix all work well and create distinctly different versions of this dessert.
Why is the center still jiggly when I take the bars out of the oven?
That’s exactly right. The center should be slightly jiggly when it comes out, since it firms up into the signature gooey texture as the bars cool.
Can I use low-fat cream cheese?
Full-fat cream cheese gives the richest, creamiest texture. Low-fat versions can work but may result in a slightly less indulgent topping.
How do I get clean, neat slices?
Make sure the bars are completely cool, or even chilled, before slicing, and wipe your knife clean between cuts.
Can I double the recipe?
Yes, though you’ll need two 9×13-inch pans, since a single pan cannot hold a doubled batch without significantly affecting the baking time and texture.
