What Is Gooey Butter Cake?
Gooey butter cake is a classic St. Louis dessert that originated in the 1930s. It’s traditionally a flat, dense cake with a gooey, buttery layer on top. This bar version simplifies the concept using a yellow cake mix for the crust and a rich cream cheese filling, creating a dessert that’s easier to make but just as delicious. The result is a soft, buttery base topped with a gooey, sweet, slightly tangy cream cheese layer that crackles beautifully on top.
Ingredients You’ll Need
For the Crust:
· 1 box (15.25 oz) yellow cake mix
· ½ cup unsalted butter, melted
· 1 large egg
For the Filling:
· 8 oz cream cheese, softened to room temperature
· 2 large eggs
· 1 teaspoon vanilla extract
· 4 cups powdered sugar
· ½ cup unsalted butter, melted
Optional add-ins: ½ cup mini chocolate chips, ½ cup white chocolate chips, 1 teaspoon cinnamon, ¼ cup lemon juice and 1 tablespoon lemon zest for a lemon version, ½ cup caramel sauce swirled on top, ½ cup chopped pecans.
Note: For a chocolate version, use chocolate cake mix and add ¼ cup cocoa powder to the filling. For a gluten-free version, use a gluten-free yellow cake mix. For a dairy-free option, use plant-based butter and dairy-free cream cheese.
Step-by-Step Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease a 9×13-inch glass baking dish with butter or non-stick cooking spray.
- Make the Crust: In a large bowl, combine the yellow cake mix, ½ cup melted butter, and 1 egg. Mix until a soft, thick dough forms. The dough should hold together when pressed.
- Press the Crust: Press the dough evenly into the bottom of the prepared baking dish. Use your fingers or the back of a spoon to create an even layer that covers the entire bottom of the pan.
- Make the Filling: In a separate bowl, beat the softened cream cheese until smooth and creamy. Add the 2 eggs and vanilla extract, mixing well until fully incorporated.
- Add Powdered Sugar and Butter: Gradually add the powdered sugar and beat until fully incorporated. Slowly mix in the ½ cup melted butter until the filling is smooth and pourable. Scrape down the sides of the bowl as needed.
- Pour Over Crust: Pour the cream cheese filling evenly over the crust. Use a spatula to spread it into an even layer.
- Bake: Bake for 40–45 minutes, until the top is golden brown and has a crackled appearance. The center will still be slightly jiggly—this is what makes it gooey. Do not overbake.
- Cool Completely: Remove from the oven and let cool completely at room temperature before cutting into squares. This allows the filling to set properly. For best results, refrigerate for 1–2 hours before slicing.
Tips for the Best Ooey Gooey Butter Cake Bars
· Use Room Temperature Cream Cheese: Softened cream cheese beats smooth and lump-free. Let it sit at room temperature for 30 minutes before mixing.
· Don’t Overbake: The center should still be slightly jiggly when you remove it from the oven. It will continue to set as it cools. Overbaking makes the bars dry instead of gooey.
· Cool Completely Before Cutting: These bars need time to set. If you cut them while warm, they’ll be too gooey and messy. Let them cool completely at room temperature, then refrigerate for cleaner cuts.
· Use a Glass Baking Dish: A glass dish conducts heat evenly and allows you to see when the bars are perfectly golden.
· Sift the Powdered Sugar: Sifting prevents lumps in the filling and ensures a smooth, creamy texture.
· Press the Crust Firmly: A well-packed crust prevents crumbling when slicing.
· Store in the Refrigerator: These bars are best stored in the refrigerator. They stay fresh for up to 5 days.
Variations & Substitutions
· Chocolate Gooey Butter Cake Bars: Use chocolate cake mix for the crust and add ¼ cup cocoa powder to the filling.
· Lemon Gooey Butter Bars: Add ¼ cup fresh lemon juice and 1 tablespoon lemon zest to the filling. Use lemon cake mix for the crust.
· Strawberry Gooey Butter Bars: Swirl ½ cup strawberry preserves into the filling before baking.
· Caramel Gooey Butter Bars: Drizzle caramel sauce over the top before baking and again after cooling.
· Red Velvet Gooey Butter Bars: Use red velvet cake mix for the crust and add 1 tablespoon cocoa powder to the filling.
· Spice Cake Gooey Butter Bars: Use spice cake mix for the crust and add 1 teaspoon cinnamon to the filling.
Frequently Asked Questions
What is gooey butter cake?
Gooey butter cake is a classic St. Louis dessert with a buttery cake base and a gooey, sweet cream cheese topping. This bar version uses a cake mix for convenience.
Why is my gooey butter cake not gooey?
If your bars turned out dry, they were likely overbaked. The center should still be slightly jiggly when you remove it from the oven. It will set as it cools. Also, make sure to measure the powdered sugar accurately—too much will make the filling dry.
Can I use a different cake mix?
Yes! Yellow cake mix is classic, but you can use white, butter, lemon, strawberry, red velvet, chocolate, or spice cake mix. Each creates a different flavor profile.
How do I store these bars?
Store in an airtight container in the refrigerator for up to 5 days. Let them sit at room temperature for 10 minutes before serving for the best texture.
Can I freeze gooey butter cake bars?
Yes! Wrap individual bars tightly in plastic wrap and foil, or place in a freezer-safe container with parchment paper between layers. Freeze for up to 3 months. Thaw in the refrigerator overnight.
Can I make these bars ahead of time?
Absolutely. These bars are perfect for making ahead. Prepare them up to 2 days in advance and store in the refrigerator. The flavors actually deepen over time.
Why is my filling lumpy?
Lumpy filling usually means the cream cheese wasn’t fully softened or the powdered sugar wasn’t sifted. Make sure both are at room temperature and sift the powdered sugar before adding.
Can I cut the recipe in half?
Yes! Use an 8×8-inch baking dish and halve all ingredients. Reduce baking time to 30–35 minutes.
