For Serving
Extra powdered sugar, optional
These quantities make a rich, sweet dessert with a soft filling and a cake-like base. For the smoothest texture, allow the cream cheese and eggs to come closer to room temperature before mixing.
Kitchen Tools You'll Need
No special baking equipment is required.
Gather these items before you start:
9-by-13-inch baking pan
Large mixing bowl
Medium mixing bowl
Electric hand mixer or stand mixer
Rubber spatula
Measuring cups and spoons
Parchment paper, optional
Wire cooling rack
Sharp knife for cutting the bars
A metal baking pan works well for this recipe. If you use a glass dish, the baking time may vary slightly, so watch the edges and center carefully.
How to Make Ooey Gooey Bars
Ready to make a dessert that tastes like a little square of happiness? Let's get started!
Step 1: Preheat the Oven
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 if you'd like to lift the bars out after cooling.
Preparing the pan first makes the rest of the process much easier.
Step 2: Make the Cake Base
In a mixing bowl, combine the yellow cake mix, one egg, and ½ cup melted butter.
Stir until the ingredients form a thick dough.
The mixture will be much thicker than ordinary cake batter. That's exactly what you want!
Press the dough evenly into the bottom of your prepared baking pan.
Use your fingertips or a spatula to spread it into the corners, keeping the layer as even as possible.
Don't worry if it looks a little rustic. The creamy topping will cover most of it.
Step 3: Prepare the Cream Cheese Filling
In a separate bowl, beat the softened cream cheese until smooth.
Add the two eggs and vanilla extract, then mix until everything is combined.
Pour in the remaining ½ cup of melted butter, making sure it has cooled slightly so it doesn't feel hot to the touch.
Beat again until the mixture is smooth.
Gradually add the powdered sugar, mixing at a low speed at first to avoid creating a cloud of sugar around your kitchen!
Continue until the filling is thick, creamy, and free of large lumps.
Step 4: Spread the Filling Over the Base
Pour the cream cheese mixture over the cake layer.
Use a spatula to spread it evenly from edge to edge.
Try to keep the filling at a consistent thickness so the bars bake evenly.
At this point, you'll already see the two layers coming together beautifully. That creamy topping is what gives these bars their signature texture.
Step 5: Bake Until Just Set
Place the pan on the center rack of the oven.
Bake for approximately 35–45 minutes, checking toward the earlier end of the baking window.
The edges should look lightly golden, and the top should be set around the outside while the center may still have a gentle wobble.
You don't want the filling to look completely liquid, but you also don't want to bake it until it's dry and firm all the way through.
Every oven behaves a little differently, so use the appearance of the bars as your guide rather than relying on the clock alone.
Step 6: Let the Bars Cool
Remove the pan from the oven and place it on a wire rack.
Allow the bars to cool completely before cutting.
I know, I know—waiting is the hardest part!
But cutting too soon can cause the soft filling to collapse or smear across the knife.
As the bars cool, the center becomes more stable while keeping that lovely creamy texture.
Step 7: Add Powdered Sugar and Slice
Once the bars have cooled, dust the top with a little powdered sugar if desired.
Use a sharp knife to cut them into squares or rectangles.
For especially neat edges, wipe the knife clean between cuts.
Serve them on a platter, pack them into a dessert box, or enjoy a square with your favorite cup of coffee.
Just be warned: these are the kind of treats that tend to disappear quickly!
Tips for the Best Ooey Gooey Bars
A few simple tricks can make a noticeable difference in the final texture.
Soften the Cream Cheese First
Cold cream cheese can leave lumps in the filling.
Let it soften at room temperature before mixing, or use a gentle method to soften it without melting it.
Don't Overmix the Filling
Beat the mixture until smooth and combined, but avoid unnecessary mixing once everything is incorporated.
A smooth filling helps create that soft, creamy texture.
Watch the Baking Time
Overbaking is one of the easiest ways to lose the signature gooey texture.
Look for lightly golden edges and a center that's set around the outside but still slightly soft in the middle.
Cool Before Cutting
This is especially important if you want neat dessert squares.
The filling needs time to settle after baking.
Use Parchment Paper for Easy Removal
Parchment paper can make lifting the cooled bars out of the pan much easier.
Leave a little overhang on two sides so you can carefully lift the slab onto a cutting board.
Adjust the Sweetness to Your Taste
The powdered sugar gives the topping its classic sweetness. If you prefer a slightly less sweet dessert, start at the lower end of the suggested range, understanding that the filling's thickness and final texture may change slightly.
Delicious Variations to Try
Once you've made the classic version, there are plenty of ways to experiment!
Chocolate Ooey Gooey Bars
Use chocolate cake mix instead of yellow cake mix.
The result is a rich chocolate base paired with a creamy topping. You can also add a small handful of chocolate chips to the filling.
Lemon Ooey Gooey Bars
Use lemon cake mix for the base and add a little finely grated lemon zest to the filling.
The bright citrus flavor provides a refreshing contrast to the sweet cream cheese topping.
Strawberry Ooey Gooey Bars
Try strawberry cake mix for a pretty pink base.
For a stronger strawberry flavor, serve the bars with fresh sliced strawberries rather than adding too much moisture to the filling.
Spice Cake Ooey Gooey Bars
Use spice cake mix for a cozy variation with warm cinnamon and other baking spices.
These are especially lovely during autumn and the holiday season.
Chocolate Chip Ooey Gooey Bars
Fold a small handful of chocolate chips into the filling before spreading it over the base.
Semi-sweet chocolate chips work particularly well because they balance the sweetness of the dessert.
Nutty Ooey Gooey Bars
If nuts are suitable for everyone you're serving, sprinkle chopped pecans or walnuts over the filling before baking.
They add a little crunch to contrast with the soft center.
What to Serve With Ooey Gooey Bars
These bars are rich enough to enjoy on their own, but a few simple additions can make them even more special.
Coffee or Espresso
A cup of black coffee or espresso provides a pleasant contrast to the sweet filling.
Fresh Berries
Strawberries, raspberries, or blueberries add fresh flavor and color to the dessert plate.
Vanilla Ice Cream
Serve a small square alongside vanilla ice cream for an extra-indulgent dessert.
Whipped Cream
A spoonful of lightly sweetened whipped cream adds a soft, airy contrast.
A Holiday Dessert Platter
Cut the bars into smaller pieces and arrange them with cookies, brownies, and other bite-sized treats.
They're especially convenient when you're serving a crowd with different dessert preferences.
Make-Ahead Instructions
Ooey gooey bars are an excellent make-ahead dessert.
Bake the bars according to the recipe, allow them to cool completely, and cover the pan.
Because the filling contains cream cheese and eggs, refrigerate the cooled bars rather than leaving them at room temperature for extended periods.
For the best appearance, dust them with powdered sugar shortly before serving.
If you're preparing them for a party, you can cut the bars in advance and arrange them on a covered platter or in an airtight container in the refrigerator.
How to Store Ooey Gooey Bars
Because these bars contain a cream cheese and egg-based filling, they should be refrigerated after cooling.
Place the bars in an airtight container and refrigerate them for approximately 3–4 days for best quality.
You can separate layers with parchment paper to prevent the bars from sticking together.
Before serving, let a portion sit at room temperature briefly if you prefer a softer texture, but don't leave the entire batch out for extended periods.
Can You Freeze Ooey Gooey Bars?
Yes! These bars can be frozen for later enjoyment.
For the best results:
Allow the bars to cool completely.
Cut them into individual portions.
Wrap each portion or separate the layers with parchment paper.
Place them in a freezer-safe airtight container.
Freeze for up to about 2–3 months for best quality.
Thaw in the refrigerator before serving.
The texture may change slightly after freezing and thawing, but the bars should still be delicious.
If you're planning to serve them to guests, thaw them in the refrigerator overnight and add a fresh dusting of powdered sugar just before serving.
Frequently Asked Questions
Why are my ooey gooey bars too runny?
They may be underbaked, still warm, or made with ingredients that were measured differently from the recipe. Allow the bars to cool completely before judging the filling's consistency. If the center remains liquid after cooling, the bars may need additional baking time the next time you make them.
Why did my ooey gooey bars turn out dry?
Overbaking is a common cause. Remove the pan when the edges are lightly golden and the center is mostly set but still soft. Remember that the filling will continue to settle as the bars cool.
Do I need to refrigerate ooey gooey bars?
Yes. This cream cheese version contains an egg-based filling, so refrigerate the cooled bars promptly and store them in an airtight container.
Can I use homemade cake batter instead of boxed cake mix?
You can experiment with a homemade cake-style base, but the quantities and texture may differ. The boxed cake mix version is designed for convenience and produces a dense, dough-like layer rather than ordinary cake batter.
Can I make ooey gooey bars without a mixer?
Yes, although softened cream cheese is much easier to blend smoothly with an electric mixer. If mixing by hand, use a sturdy whisk or spatula and work out the cream cheese lumps before adding the remaining ingredients.
How do I cut the bars neatly?
Let the bars cool completely, then use a sharp knife. Wipe the blade between cuts, and consider chilling the bars briefly if you want particularly clean edges.
Can I make these bars in a different flavor?
Absolutely! Chocolate, lemon, strawberry, and spice cake mixes are all fun options. Keep in mind that changing the cake mix can affect the flavor, color, and sweetness of the finished dessert.
Can I make ooey gooey bars the day before serving?
Definitely. Bake and cool them, then cover and refrigerate. Add the powdered sugar just before serving for the prettiest finish.
