St. Louis gooey butter cake features a dense, gooey cream cheese filling atop a buttery cake crust. This iconic Missouri dessert is irresistibly rich and a must-try family indulgence.
Preheat oven to 350°F and lightly grease a 9x13 inch baking pan.
Combine yellow cake mix, 8 tbsp melted butter, and 1 egg in a bowl; mix until a soft dough forms. Press evenly into the bottom of the prepared pan.
In a separate bowl, beat cream cheese until smooth. Add 2 eggs, vanilla extract, salt, and confectioners’ sugar; blend until creamy and lump-free.
Spread the cream cheese filling gently over the cake crust to cover completely, ensuring even distribution.
Bake at 350°F for 40–45 minutes; edges will be golden and center slightly jiggles. Cool in pan before slicing for best gooey texture.
