1 large egg
1/2 cup unsalted butter, melted
For the cream cheese filling
8 ounces cream cheese, softened
2 large eggs
1 teaspoon vanilla extract
1/2 cup unsalted butter, melted and slightly cooled
3 1/2 to 4 cups powdered sugar
Optional topping
Extra powdered sugar for dusting
Mini chocolate chips

A quick ingredient note: This recipe is intentionally rich and sweet. Start with 3 1/2 cups of powdered sugar in the filling, then add the remaining 1/2 cup if you prefer a sweeter, firmer topping.
Helpful Tools for Making Ooey Gooey Bars
You won't need any specialized baking equipment.
9-by-13-inch baking pan
Large mixing bowl
Medium mixing bowl
Hand mixer or stand mixer
Rubber spatula
Measuring cups and spoons
Parchment paper, optional
Wire cooling rack
Sharp knife for slicing
Lining the pan with parchment paper is especially helpful if you want to lift the cooled bars out before cutting them into neat squares.
Ingredient Substitutions and Add-Ins
One of the best things about this recipe is how easy it is to adapt.
Use a different cake mix
Yellow cake mix gives the bars their classic buttery flavor, but white cake mix also works well.
For a richer variation, try a butter-flavored cake mix. Chocolate cake mix can create a completely different dessert with a chocolate base and creamy topping.
Add a little citrus
Mix 1–2 teaspoons of finely grated lemon zest into the cream cheese layer for a fresh, tangy twist. This works particularly well if you're serving the bars in spring or summer.
Make them chocolatey
Fold a handful of mini chocolate chips into the filling or sprinkle them over the top before baking. White chocolate chips are another delicious option.
Add nuts
Chopped pecans or walnuts give the bars a little crunch that contrasts nicely with the creamy center.
Try a different extract
Vanilla is the classic choice, but a small amount of almond extract can add a lovely bakery-style flavor. Use it sparingly because almond extract is quite strong.
Can you use reduced-fat cream cheese?
Full-fat cream cheese generally gives the richest flavor and creamiest texture. Reduced-fat cream cheese may work, but the filling can turn out softer or slightly different in texture. Avoid whipped cream cheese, which has a different consistency.
How to Make Ooey Gooey Bars
These bars are wonderfully straightforward. Prepare the base, mix the topping, layer everything in the pan, and bake until the edges are set while the center remains soft.
Step 1: Prepare the oven and pan
Preheat your oven to 350°F (175°C).
Lightly grease a 9-by-13-inch baking pan or line it with parchment paper, leaving a little overhang on the sides for easy removal.
Step 2: Make the cake base
In a large bowl, combine the yellow cake mix, one egg, and 1/2 cup melted butter.
Stir until a thick dough forms. It will be much denser than regular cake batter, so don't worry if it looks a little stiff.
Press the mixture evenly into the bottom of the prepared pan using clean hands or a spatula.
Try to make the layer relatively even so it bakes at a consistent rate.
Step 3: Beat the cream cheese
In a separate bowl, beat the softened cream cheese until smooth and creamy.
This step matters! Starting with softened cream cheese helps prevent little lumps from appearing in your filling.
Add the two eggs and vanilla extract. Beat until everything is well combined.
Step 4: Add the butter and powdered sugar
Slowly mix in the melted, slightly cooled butter.
Add the powdered sugar gradually, mixing on low speed at first to keep it from puffing out of the bowl.
Continue mixing until the filling is smooth and thick. Scrape down the sides of the bowl if needed.
Step 5: Add the filling
Pour the cream cheese mixture over the cake base.
Use a spatula to spread it evenly from edge to edge.
The filling will look soft and glossy. That's exactly what you want!
Step 6: Bake until just set
Bake for approximately 35–45 minutes, checking toward the earlier end of the range.
The edges should look set and lightly golden, while the center should remain a little soft. It shouldn't look completely liquid or slosh when you gently move the pan.
Remember, these are Ooey Gooey Bars. You want a soft center, not a dry cake!
Ovens and pans vary, so use the appearance of the bars as your guide rather than relying on the timer alone.
Step 7: Cool before slicing
Remove the pan from the oven and place it on a wire rack.
Allow the bars to cool completely before cutting. The filling will continue to set as it cools, making the bars easier to slice.
For especially neat squares, refrigerate the cooled pan for 30–60 minutes before cutting.
Dust with powdered sugar if you like, then serve and enjoy!
How to Tell When Ooey Gooey Bars Are Done
The secret to the right texture is knowing when to stop baking.
Look for these signs:
The edges are set and lightly golden.
The top looks mostly set rather than wet.
The center remains soft but isn't liquid.
The bars hold their shape better as they cool.
Don't wait for the entire surface to become firm like a regular cake. That can lead to overbaking and a drier filling.
If the center still looks very wet at the end of the suggested baking time, continue baking in short increments and check again.
Tips for the Best Ooey Gooey Bars
Soften the cream cheese first
Cold cream cheese is harder to mix smoothly and can leave lumps in the filling. Let it sit at room temperature until soft enough to beat easily.
Let the melted butter cool slightly
Very hot butter can affect the texture of the filling. Let it cool for a few minutes before adding it to the cream cheese mixture.
Don't overmix
Mix until the ingredients are smooth and combined. Excessive mixing can incorporate extra air, which may affect the final texture.
Watch the baking time
Every oven is different. Start checking around 35 minutes, and remember that the center will firm up as the bars cool.
Cool completely before cutting
I know, waiting is the hardest part! But slicing the bars while they're hot can cause the creamy topping to smear and the base to crumble.
Use a clean knife
For tidy squares, wipe the knife with a damp cloth between cuts. Chilling the bars briefly also makes slicing much easier.
What to Serve With Ooey Gooey Bars
These bars are delicious on their own, but a simple accompaniment can make them feel extra special.
Try serving them with:
Coffee or espresso: The slight bitterness balances the sweetness.
Hot tea: A lovely choice for an afternoon treat.
Fresh strawberries or raspberries: Their bright, fruity flavor cuts through the richness.
Vanilla ice cream: Perfect if you enjoy serving the bars slightly warm.
Fresh whipped cream: A light, fluffy topping makes a pretty presentation.
A drizzle of chocolate sauce: Especially delicious if you've added chocolate chips.
For a dessert platter, cut the bars into small squares and arrange them alongside brownies, cookies, and fresh berries. They make a lovely addition to a holiday dessert table.
Can You Make Ooey Gooey Bars Ahead of Time?
Absolutely! These bars are a great make-ahead dessert.
Bake them a day before serving, let them cool completely, and store them covered in the refrigerator. Chilling also helps the filling firm up, which makes the bars easier to cut into clean squares.
For the best flavor and texture, take them out of the refrigerator shortly before serving so they can lose some of their chill.
How to Store Ooey Gooey Bars
Because the filling contains cream cheese and eggs, these bars should be refrigerated after cooling.
In the refrigerator
Place the cooled bars in an airtight container or cover the baking pan tightly. Refrigerate for 3–5 days.
For the neatest storage, layer the bars with parchment paper so they don't stick together.
Can you freeze Ooey Gooey Bars?
Yes! These bars can be frozen, although the cream cheese layer may have a slight texture change after thawing.
Let the bars cool completely.
Cut them into individual squares.
Wrap each piece tightly or place the squares in a freezer-safe container.
Freeze for up to 2 months for best quality.
Thaw overnight in the refrigerator before serving.
Avoid leaving the bars at room temperature for extended periods because of their cream cheese filling.

Frequently Asked Questions
Why are my Ooey Gooey Bars runny in the middle?
They may need more baking time, or they may have been sliced before cooling completely. The center should be soft and creamy, but it shouldn't look liquid. Allow the bars to cool fully so the filling has time to set.
Why did my Ooey Gooey Bars turn out dry?
Overbaking is a common reason. The edges should be set while the middle remains soft. Leaving the bars in the oven until the entire top feels firm can make the filling less creamy.
Can I make Ooey Gooey Bars without cake mix?
Yes, but you'll need a different cake-base recipe with measured flour, sugar, leavening, and other ingredients. Cake mix is what makes this version especially quick and convenient.
Do Ooey Gooey Bars need to be refrigerated?
Yes. Since the topping contains cream cheese and eggs, refrigerate the bars once they've cooled. Store them in an airtight container and serve them chilled or let them sit out briefly before serving.
Can I use salted butter?
Yes. If you use salted butter, you may want to omit any additional salt in a from-scratch variation. The cake mix already contains salt, so the recipe generally doesn't need much extra.
Can I make these bars in a smaller pan?
A smaller pan will make the layers thicker and may require a longer baking time. The center can be harder to bake evenly, so a 9-by-13-inch pan is the recommended choice for this recipe.
Can I add fruit to the filling?
You can experiment with small amounts of fruit, but fresh fruit releases moisture and may change the texture. For a more reliable result, serve the bars with fresh berries on the side or use a small amount of fruit zest for flavor.
How do I cut clean squares?
Cool the bars completely, then chill them briefly if needed. Use a sharp knife and wipe the blade between cuts. This helps keep the creamy filling from dragging across each slice.
