Gooey Butter Cake Bars are also known as Neiman Marcus bars and are made with only 6 ingredients.

Step 1: Preheat Oven
Set your oven to 350°F (175°C).

Step 2: Make the Crust
In a medium bowl, mix together the dry cake mix, melted butter, and 1 egg until smooth. Press the mixture evenly into the bottom of a greased 9×13-inch pan. Set aside.

Step 3: Prepare the Gooey Layer
In a large bowl, beat the cream cheese until smooth. Add the eggs and continue mixing for 1–2 minutes. Stir in the powdered sugar until fully combined.

Step 4: Bake
Pour the cream cheese mixture evenly over the crust. Bake at 350°F for 25–30 minutes, until the edges are set but the center is still slightly soft. Avoid overbaking.

Step 5: Cool and Serve
Allow the bars to cool completely before cutting—this is key for that perfectly gooey texture.
