These Ooey Gooey Bars are rich, buttery, soft in the center, and lightly crisp around the edges. A simple cake-mix crust supports a creamy layer made with cream cheese, powdered sugar, eggs, and vanilla, creating a dessert that is part cookie bar, part cheesecake, and part gooey butter cake.
The recipe is easy enough for beginner bakers but indulgent enough for holidays, potlucks, bake sales, family gatherings, birthday parties, church suppers, and weekend desserts. The bars come together with common grocery-store ingredients and require only one baking pan.
The bottom layer bakes into a dense, buttery crust, while the top remains soft, sweet, and slightly custard-like. As the bars cool, the center sets enough to slice while keeping the gooey texture that makes this dessert so popular.
They can be served plain, dusted with powdered sugar, topped with berries, drizzled with chocolate or caramel, or customized with chocolate chips, nuts, lemon, pumpkin, or coconut.
For the cleanest slices, allow the bars to cool completely before cutting. For the softest and most indulgent texture, serve them slightly warm with vanilla ice cream or whipped cream.
Why You Will Love These Ooey Gooey Bars

The filling is rich and creamy but does not require a complicated cheesecake method or water bath.
The bars are easy to transport, making them ideal for parties, potlucks, bake sales, office events, and holiday dessert trays.
They can be prepared ahead and stored in the refrigerator until needed.
The base recipe is also easy to customize with different cake-mix flavors, extracts, chips, fruit, spices, or toppings.
What Are Ooey Gooey Bars?
Ooey Gooey Bars are a layered dessert inspired by gooey butter cake.
The bottom layer is usually made with boxed cake mix, melted butter, and an egg. This mixture is pressed into the baking pan rather than prepared as a traditional pourable cake batter.
The top layer combines cream cheese, eggs, vanilla, butter, and powdered sugar. It bakes into a soft, sweet filling with a lightly crackled surface.
The bars are intentionally not baked until dry or cake-like. Their defining feature is the soft, slightly gooey center.

Ingredient Notes
Yellow Cake Mix
Yellow cake mix creates the classic buttery flavor and golden color.
White cake mix produces a milder base, while butter cake mix creates an even richer result.
Do not prepare the cake mix according to the instructions on the box. Use the dry mix directly in the recipe.
Butter
Butter gives both layers their rich flavor.
Allow the butter used in the filling to cool slightly so it does not cook the eggs or melt the cream cheese excessively.
Eggs
The crust uses one egg for structure.
The filling uses two eggs to help it set while maintaining a soft texture.
Use large eggs unless a different size is specified.
Cream Cheese
Use full-fat block-style cream cheese for the richest, most stable filling.
Spreadable cream cheese in a tub contains more moisture and can produce a softer result.
Allow the cream cheese to soften at room temperature before mixing.
Powdered Sugar
Powdered sugar dissolves easily and gives the filling its smooth texture and sweet flavor.
Measure it carefully and add it gradually to reduce mess.
Vanilla
Vanilla rounds out the sweetness and gives the bars a warm bakery-style flavor.
Almond, lemon, maple, or coconut extract can be used for variations.
Kitchen Equipment
You will need a 9-by-13-inch baking pan, parchment paper, large mixing bowl, medium mixing bowl, electric hand mixer or stand mixer, silicone spatula, measuring cups, measuring spoons, and wire cooling rack.
An offset spatula is useful for spreading the thick crust mixture and leveling the filling.
How to Make Ooey Gooey Bars
Step 1: Preheat the Oven
Preheat the oven to 350°F.
Line a 9-by-13-inch baking pan with parchment paper, leaving some overhang for easy removal.
Lightly grease the parchment and exposed sides of the pan.
Step 2: Make the Crust
Place the dry cake mix in a large bowl.
Add the melted butter, egg, and optional vanilla.
Mix until a thick, soft dough forms.
The mixture will be much thicker than regular cake batter.
Step 3: Press the Crust into the Pan
Transfer the dough to the prepared baking pan.
Press it into an even layer across the bottom.
Use lightly greased hands, parchment paper, or the bottom of a measuring cup to smooth the surface.
Step 4: Beat the Cream Cheese
Place the softened cream cheese in a clean mixing bowl.
Beat until smooth and free of large lumps.
Step 5: Add the Eggs and Vanilla
Add the eggs one at a time, mixing after each addition.
Add the vanilla and salt.
Mix until smooth.
Step 6: Add the Butter
Pour in the melted and slightly cooled butter.
Beat until fully incorporated.
Step 7: Add the Powdered Sugar
Add the powdered sugar gradually.
Mix on low speed at first to prevent it from flying out of the bowl.
Continue mixing until the filling is smooth, thick, and creamy.
Step 8: Spread the Filling
Pour the cream cheese mixture over the crust.
Spread it gently into an even layer.
Step 9: Bake
Bake for approximately 35 to 45 minutes.
The edges should look set and lightly golden.
The center should remain slightly soft and may jiggle gently when the pan is moved.
Step 10: Do Not Overbake
Remove the bars before the center becomes completely firm.
They continue setting as they cool.
Overbaking removes the signature gooey texture.
Step 11: Cool Completely
Place the pan on a wire rack.
Allow the bars to cool completely before slicing.
For the neatest squares, refrigerate them for one to two hours after cooling.
Step 12: Slice and Serve
Lift the chilled slab from the pan using the parchment overhang.
Cut into squares with a sharp knife.
Dust with powdered sugar before serving when desired.
How to Know When Ooey Gooey Bars Are Done
The outer two inches should look set and lightly golden.
The center should no longer look raw or liquid, but it should remain soft.
A toothpick inserted near the edge should come out mostly clean.
A toothpick inserted in the center may have moist crumbs or soft filling attached.
The surface may look puffed and slightly crackled before settling as it cools.
How to Keep the Center Gooey
Use the correct pan size.
Do not reduce the filling ingredients dramatically.
Bake at 350°F rather than using excessively high heat.
Begin checking early.
Remove the pan while the center still moves slightly.
Allow the bars to finish setting through residual heat as they cool.
How to Prevent a Dry Crust
Measure the cake mix and butter accurately.
Do not prebake the crust unless a variation specifically requires it.
Press the mixture evenly so thin areas do not overcook.
Do not bake the completed bars longer than necessary.
Store the bars in an airtight container after cooling.
How to Get a Smooth Cream Cheese Layer
Use softened block-style cream cheese.
Beat the cream cheese alone before adding other ingredients.
Add eggs one at a time.
Use slightly cooled melted butter.
Add powdered sugar gradually.
Scrape the bowl several times during mixing.
How to Get Clean Slices
Cool the bars completely.
Refrigerate them until firm.
Lift the entire slab from the pan before cutting.
Use a large sharp knife.
Wipe the blade between slices.
For especially neat squares, warm the knife under hot water and dry it before each cut.
Tips for the Best Ooey Gooey Bars
Use block-style full-fat cream cheese.
Bring the cream cheese to room temperature.
Allow melted butter to cool slightly.
Line the pan with parchment paper.
Press the crust into an even layer.
Do not overmix the filling after it becomes smooth.
Do not overbake.
Cool completely before slicing.
Cut small portions because the bars are rich.

Can You Make Ooey Gooey Bars without Cake Mix?
Yes. A homemade crust can be prepared with flour, sugar, baking powder, salt, butter, egg, and vanilla.
The homemade version requires more measuring but allows greater control over sweetness and flavor.
The texture may differ slightly from the classic cake-mix version.
Can You Use Another Cake-Mix Flavor?
Yes. Chocolate, white, lemon, strawberry, red velvet, spice, butter pecan, and funfetti cake mixes all work.
Choose fillings and toppings that complement the selected flavor.
Can You Use Margarine Instead of Butter?
Margarine can be used, but the flavor and texture may differ.
Choose a baking margarine with a high fat content rather than a soft spread with a high water content.
Butter gives the richest flavor and most reliable texture.
Can You Use Low-Fat Cream Cheese?
Reduced-fat block cream cheese can be used, but the filling may be softer and less rich.
Avoid whipped cream cheese and very soft tub-style products when possible.
Can You Reduce the Powdered Sugar?
You can reduce it slightly, but a major reduction changes the sweetness, structure, and texture of the filling.
Use dark chocolate toppings, berries, coffee, or flaky salt to balance the sweetness rather than changing the filling dramatically.
Can You Make the Bars Gluten-Free?
Use a gluten-free boxed cake mix and verify that the remaining ingredients are gluten-free.
Check powdered sugar, vanilla, toppings, chips, and decorative ingredients for cross-contact warnings.
The exact texture depends on the flour blend used in the cake mix.
Can You Make Them Dairy-Free?
Use dairy-free cake mix, plant-based baking butter, dairy-free cream cheese, and suitable toppings.
Choose plant-based products designed for baking, as soft spreads may contain too much water.
The final texture will depend heavily on the dairy-free cream cheese brand.
Can You Make Ooey Gooey Bars Ahead?
Yes. The bars can be prepared one to three days before serving.
Cool them completely, cover the pan, and refrigerate.
Slice shortly before serving for the cleanest presentation.
Allow refrigerated bars to stand at room temperature for approximately 15 minutes when you prefer a softer center.
How to Serve Ooey Gooey Bars
Serve the bars at room temperature for a soft texture.
Serve them chilled for cleaner slices and a firmer cream cheese layer.
Warm individual portions briefly for an extra-gooey dessert.
Dust with powdered sugar for a classic finish.
Add whipped cream, berries, caramel sauce, chocolate sauce, or vanilla ice cream for a plated dessert.

The bars are very rich, so unsweetened beverages and fresh fruit provide a useful contrast.
How to Store Ooey Gooey Bars
Allow the bars to cool completely.
Place them in an airtight food storage container with parchment paper between layers.
Because the filling contains cream cheese and eggs, refrigeration is the safest storage method.
Store in the refrigerator for up to five days.
Allow them to stand briefly at room temperature before serving when you prefer a softer texture.
Can You Freeze Ooey Gooey Bars?
Yes. Cool and slice the bars first.
Wrap individual squares in plastic wrap or parchment, then place them in a freezer-safe container.

Thaw overnight in the refrigerator.
Serve chilled, bring to room temperature, or warm briefly before serving.
How to Reheat Ooey Gooey Bars
Place one bar on a microwave-safe plate.
Microwave for approximately 10 to 15 seconds.
The center should soften without becoming excessively hot.
For several bars, place them in a covered baking dish and warm briefly in a low oven.
Do not overheat because the filling can become oily or separate.
Common Mistakes to Avoid
Do not prepare the cake mix according to the box instructions.
Avoid using cold, lumpy cream cheese.
Do not pour very hot butter into the filling.
Avoid adding all the powdered sugar at once.
Do not use a pan that is too small.
