How to Make Decadent Gooey Butter Cake Bars
-
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy cleanup.
-
Combine the yellow cake mix, melted butter, and 1 egg in a mixing bowl. Stir everything together until a thick, smooth dough forms.
-
Spread the dough evenly into the bottom of the prepared baking pan, pressing it down firmly to ensure it covers the entire surface evenly.
-
Beat the softened cream cheese in another bowl until it’s nice and smooth. This will be the creamy filling that melts in your mouth!
-
Mix in the 2 eggs and vanilla extract to the cream cheese, whisking until fully combined for a luscious filling.

Gradually add the powdered sugar to the cream cheese mixture, stirring until you achieve a smooth and creamy consistency that’s free of lumps.
-
Pour the cream cheese mixture over the cake base, spreading it out evenly with a spatula to ensure every bite is gooey and delicious.

Bake the bars for 40-45 minutes. Look for the edges to be set while the center remains slightly jiggly and golden—this is key to that gooey texture!

Cool the bars in the pan for at least 30 minutes. This allows them to firm up slightly, making slicing easier.

Decadent Gooey Butter Cake Bars Recipe FAQs
What kind of cake mix should I use for Decadent Gooey Butter Cake Bars?
You can use any standard yellow cake mix for this recipe, but if you’re looking for a gluten-free option, a gluten-free cake mix works just as well! The key is to keep it simple and focus on that buttery flavor.
How do I store leftover bars?
Store your leftover Decadent Gooey Butter Cake Bars in an airtight container at room temperature for up to 3 days. If you want them to last longer, you can refrigerate them in the same container for up to a week, ensuring they remain gooey and delicious.
Can I freeze these bars, and what’s the best way to do it?
Absolutely! To freeze, wrap individual bars tightly in plastic wrap and then in aluminum foil. This double-wrapping prevents freezer burn. You can freeze them for up to 3 months. When ready to enjoy, simply thaw them in the fridge overnight and warm in the microwave for 15-20 seconds for a delightful, just-baked taste!
What do I do if my cream cheese mixture is lumpy?
If you find that your cream cheese mixture is lumpy, it could be because the cream cheese was not softened enough. Make sure you let it sit at room temperature for at least 30 minutes before mixing. If lumps persist, you can use an electric mixer on medium speed for a minute or two to smooth it out.
Can I make Decadent Gooey Butter Cake Bars without eggs?
Absolutely! You can replace the eggs in both the cake base and the creamy filling with substitutes. For each egg, use ¼ cup of applesauce or a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water, let sit for 5 minutes). This way, you can enjoy a delicious vegan alternative!
How do I know when the bars are done baking?
You’ll know the bars are done when the edges are set, and the center looks slightly jiggly yet golden. This usually takes about 40-45 minutes. If the center is completely firm, they may be overbaked, so keep an eye on them during the last few minutes!
