Equipment You’ll Need

• 9×13-inch baking pan
• Electric stand mixer or hand mixer
• Large mixing bowl
• Medium mixing bowl
• Silicone spatula
• Measuring cups and spoons
• Wire cooling rack
• Fine-mesh sieve (for dusting)

Ingredients

• For the Crust:
• 1 (18.25 ounce) box yellow cake mix
• 1/2 cup (1 stick) unsalted butter, melted
• 1 large egg, lightly beaten
• For the Filling:
• 8 ounces cream cheese, softened to room temperature
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/4 cup (1/2 stick) unsalted butter, melted
• 4 cups (1 pound) powdered sugar
• For Topping:
• 2 tablespoons powdered sugar, for dusting

Instructions

1. Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan, or line with parchment paper, leaving an overhang on the sides to easily lift the cake out later.
2. Make the Crust: In a medium bowl, combine the yellow cake mix, 1/2 cup of melted butter, and 1 lightly beaten egg. Stir until a thick, cookie-dough-like consistency forms. The mixture will be dense.
3. Press the Crust into the Pan: Evenly press the crust mixture into the bottom of the prepared baking pan. Use your fingers or the back of a spatula to create a smooth, compact layer.
4. Prepare the Filling: In a large bowl, using an electric mixer, beat the softened cream cheese until it’s smooth and free of lumps. This step is crucial for a velvety filling.
5. Combine Filling Ingredients: Add the 2 eggs and vanilla extract to the cream cheese, beating until just combined. Scrape down the sides of the bowl. With the mixer on low, slowly stream in the 1/4 cup of melted butter.
6. Add Powdered Sugar: Gradually add the powdered sugar to the mixture, about one cup at a time, mixing on low speed until everything is incorporated. Scrape the bowl again, then beat on medium speed for about 1 minute until the filling is smooth and creamy. Do not overmix.
7. Assemble the Cake: Pour the filling evenly over the prepared crust in the pan. Use a spatula to spread it to the corners.
8. Bake to Perfection: Bake for 40-50 minutes. The edges should be golden brown and set, but the center should still have a slight jiggle to it. This ‘underbaked’ center is what makes it gooey.
9. Cool Completely: Remove the cake from the oven and place it on a wire rack to cool completely in the pan. This can take up to 2 hours. Do not attempt to cut it while warm, as the filling needs to set.
10. Serve: Once completely cooled, use a fine-mesh sieve to dust the top with powdered sugar. Cut into squares and serve.

Expert Cooking Tips

• Room Temperature is Key: For the smoothest filling, ensure your cream cheese and eggs are at room temperature. This prevents lumps and helps the ingredients combine seamlessly.
• Don’t Overbake: The biggest secret to a perfect gooey butter cake is to pull it from the oven when the center is still slightly wobbly. It will continue to set as it cools, preserving that signature gooey texture.
• Cool It Down: Patience is a virtue. The cake must be completely cool before you slice it. Cutting into a warm cake will result in a messy, liquid center. Chilling it in the fridge for 30 minutes before cutting can help create clean slices.

Substitutions and Variations

While classic gooey butter cake uses a yellow cake mix, feel free to experiment. A chocolate cake mix with the same filling creates a delicious ‘gooey chocolate butter cake’. You can also add 1/2 teaspoon of almond extract to the filling for a subtle nutty flavor or a bit of lemon zest for brightness.

Common Mistakes to Avoid

The most common mistake is overbaking. If you wait for the center to be completely firm like a traditional cake, you will lose the ‘gooey’ texture. Another pitfall is not using softened cream cheese, which results in a lumpy filling. Finally, overmixing the filling can incorporate too much air, making it bake up puffy and then collapse.

Serving Suggestions

This cake is incredibly rich and is best served in small squares. It’s perfect on its own with a hot cup of coffee or a cold glass of milk. For an even more decadent dessert, serve a slice with a scoop of high-quality vanilla bean ice cream, a dollop of fresh whipped cream, or a handful of fresh berries to cut through the sweetness.

Storage and Reheating Tips

Store leftover gooey butter cake in an airtight container. It can be kept at room temperature for up to 2 days or in the refrigerator for up to 5 days. The cake is delicious served chilled directly from the fridge or brought back to room temperature.

Frequently Asked Questions

What is the texture of gooey butter cake supposed to be like?

It should have two distinct layers: a firm, dense, almost brownie-like crust on the bottom, and a soft, gooey, custard-like cream cheese layer on top. It’s not a light and fluffy cake.

Can I make this recipe from scratch without a cake mix?

Yes, you can make a from-scratch crust using flour, sugar, butter, and leavening agents. However, the St. Louis tradition heavily favors the convenience and unique texture provided by the cake mix base.

Why did my cake crack on top?

A few cracks on the surface are normal and part of its rustic charm. However, significant cracking can be caused by overmixing the filling (incorporating too much air) or baking at too high a temperature. The final dusting of powdered sugar will hide any imperfections.
