Why You’ll Love This 4-Ingredient Ooey Gooey Butter Cake Recipe

The beauty of this recipe is its simplicity. You don’t need a long list of ingredients or fancy equipment—just four everyday components and a few minutes of prep. The oven transforms basic ingredients into a buttery, gooey cake that tastes like a beloved Midwest bakery specialty.

It’s also incredibly versatile. Serve it warm with ice cream for a crowd, cut it into squares for a potluck, or enjoy the leftovers straight from the fridge. The cake keeps well, travels beautifully, and disappears fast.

Ingredients

1 box (15.25 oz) yellow cake mix
1/2 cup (1 stick) butter, melted
1 package (8 oz) cream cheese, softened
1 cup powdered sugar

Optional add-ins: 1 teaspoon vanilla extract, 2 large eggs, and a pinch of salt.

Directions

Preheat oven to 350°F and lightly grease a 9×13-inch baking dish.
In a large bowl, stir together the cake mix and melted butter (and 1 egg, if using) until a soft dough forms. Press the mixture evenly into the bottom of the prepared baking dish.
In a separate bowl, beat the softened cream cheese, powdered sugar, and vanilla if using (and the remaining egg) until smooth and creamy.
Spread the cream cheese mixture evenly over the cake base, smoothing the top with a spoon or spatula.
Bake for 30 to 35 minutes, or until the edges are golden and the center is just set—it should still look slightly gooey.
Let cool completely before cutting into squares and serving.

Serving Ideas

This cake is lovely served slightly warm with a scoop of vanilla ice cream or a dusting of powdered sugar. For a cozy dessert plate, pair it with a cup of coffee or cold milk, or drizzle with a little caramel sauce for a company-worthy finish.

Variations & Tips

Cake Mix Swap: Chocolate cake mix makes a rich, brownie-like version that’s equally delicious.
Gooey Tip: Don’t overbake—pull the cake when the center is just set so it stays gooey and soft.
Add-Ins: A sprinkle of chocolate chips or a handful of chopped pecans scattered over the top before baking adds extra texture.
Storage: Cover leftovers tightly and refrigerate up to 4 days; a few seconds in the microwave brings back that fresh-from-the-oven gooeyness.
