Ingredients
For the Chewy Crust
- 1 (15.25 oz) box yellow cake mix (do not prepare according to the box directions)
- ½ cup (1 stick) unsalted butter, melted
- 1 large egg
For the Gooey Topping
- 1 (8 oz) block cream cheese, softened to room temperature
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 1 (16 oz) box powdered sugar (about 3 ½ to 4 cups)
Optional Additions
- ½ cup chopped pecans or walnuts sprinkled on top before baking
- ½ cup semi-sweet chocolate chips folded into the cream cheese topping
- A sprinkle of flaky sea salt (like Maldon) over the baked bars to cut the sweetness
- A teaspoon of lemon zest mixed into the crust for a bright contrast
Using a standard yellow cake mix provides the perfect buttery, vanilla-forward foundation, while the block of cream cheese balances the intense sweetness of the powdered sugar topping.
Instructions
Step 1: Prepare the Oven and Pan Preheat your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, leaving a little overhang on the sides so you can easily lift the bars out later. Lightly spray the parchment with nonstick cooking spray.
Step 2: Make the Crust In a large mixing bowl, combine the dry yellow cake mix, the melted butter, and the 1 large egg. Stir together until a thick, stiff dough forms. It will have the consistency of Play-Doh.
Step 3: Press the Crust Transfer the dough into your prepared baking dish. Use your hands or the flat bottom of a measuring cup to press the dough evenly across the bottom of the pan to form the crust.
Step 4: Make the Gooey Topping In a separate large bowl, use an electric hand mixer to beat the softened cream cheese until it is completely smooth and free of lumps. Add the 2 eggs and the vanilla extract, beating until well combined. Turn the mixer to low speed and gradually add the powdered sugar, mixing until the topping is completely smooth and creamy.
Step 5: Pour and Bake Pour the cream cheese mixture evenly over the pressed cake mix crust. Use a spatula to spread it gently to the edges. Bake uncovered for 35–40 minutes. The edges should be golden brown and slightly puffed, but the very center should still have a slight jiggle to it when you gently shake the pan.
Step 6: Cool and Serve Crucial step: Remove the pan from the oven and let the bars cool completely at room temperature for at least 2 hours. If you try to cut them while they are warm, the gooey center will collapse into a liquid mess. Once cool, use the parchment overhang to lift the bars out of the pan, slice them into squares, and serve.
Tips for the Best Ooey Gooey Bars
- Soften the cream cheese If your cream cheese is cold, your topping will be lumpy, no matter how hard you mix it. Leave it on the counter for at least an hour before baking.
- Do not overbake The secret to the “gooey” texture is pulling them out of the oven while the center still looks slightly underdone. They will continue to set up as they cool in the hot pan.
- Sift the powdered sugar If your box of powdered sugar is particularly clumpy, quickly sift it before adding it to the cream cheese to ensure a perfectly silky topping.
- Use a hot knife For the cleanest, most professional-looking slices, run your knife under hot water and wipe it dry between each cut.
Delicious Variations
- Chocolate Gooey Bars Swap the yellow cake mix for a devil’s food or chocolate fudge cake mix, and add a handful of chocolate chips to the topping.
- Lemon Gooey Bars Use a lemon cake mix for the crust, and add 1 tablespoon of fresh lemon juice and a teaspoon of lemon zest to the cream cheese topping.
- Funfetti Birthday Bars Use a funfetti/confetti cake mix for the base, and sprinkle extra rainbow sprinkles over the top of the cream cheese layer before baking.
- Pumpkin Spice Bars Use a spice cake mix for the crust, and beat ½ cup of pumpkin purée and a teaspoon of pumpkin pie spice into the cream cheese layer (perfect for fall!).
What to Serve With Ooey Gooey Butter Bars
These bars are intensely rich and sweet, making them delicious with:
- A hot cup of dark, bitter coffee or espresso to cut the sweetness
- A tall, cold glass of whole milk
- A scoop of vanilla bean ice cream
- Fresh, tart berries (like raspberries or sliced strawberries)
- A dollop of unsweetened whipped cream
For the ultimate dessert plate, serve a chilled gooey bar with a side of fresh raspberries, allowing the tartness of the fruit to balance the rich, buttery cake.
Make-Ahead Instructions
This recipe is practically designed for making ahead. Because the bars need ample time to cool and set, they are actually best when made a full day in advance. You can bake them the night before your event, let them cool on the counter, and wake up to a perfectly set, easy-to-slice dessert.
Storage
Store the baked and cooled bars in an airtight container. They can be kept at room temperature for up to 3 days, or in the refrigerator for up to a week. (Many people actually prefer eating them cold straight from the fridge, as it makes the gooey center dense and fudgy!). To freeze: You can freeze the baked bars (either the whole uncut slab or individual slices) tightly wrapped in plastic wrap and aluminum foil for up to 3 months. Thaw overnight in the refrigerator before serving.
Frequently Asked Questions
Why did my bars sink in the middle? It is completely normal for the center of these bars to sink slightly as they cool! The heavy cream cheese layer puffs up in the oven and settles down as it reaches room temperature, creating that signature dense, crackly top.
Can I use any brand of cake mix? Yes, any standard 15.25 oz box of cake mix (like Betty Crocker, Duncan Hines, or Pillsbury) will work perfectly.
Do they need to be refrigerated? Because the cream cheese and eggs are fully baked, they are safe to sit at room temperature for a few days. However, storing them in the fridge will give them a longer shelf life and a wonderfully dense, chewy texture.
Perfect for Potlucks and Parties
One of the best things about this recipe is how effortlessly it feeds a crowd. Because the bars are so incredibly rich, you can cut them into small, bite-sized squares, allowing one 9×13 pan to easily serve 24 people. They travel perfectly in Tupperware without getting smashed or messy, making them the ultimate dependable dessert to bring to a neighborhood block party or a holiday cookie exchange.
Final Thoughts
Ooey Gooey Butter Bars are proof that you don’t need a complicated, from-scratch recipe to create a masterpiece. A chewy blonde brownie crust and a rich, molten cream cheese layer come together to create a multi-textured dessert that people will beg you for the recipe for. Serve them with a hot cup of coffee, pack them in a lunchbox, or bring them to your next gathering. They are sweet, dense, comforting, and wonderfully easy to make—a classic dessert staple you’ll definitely want to keep in your permanent baking rotation.
