Dessert bars are one of my favorite things to bring to summer cookouts and potlucks. They’re perfect for a crowd, easy to transport, and can be made ahead. Not only are treats like magic cookie bars, lemon crumb bars, and sour cream cookie bars always a hit at parties, but they’re also usually the first desserts to go!

These sweet and buttery Neiman Marcus bars are the perfect potluck dessert. Although the recipe isn’t actually from Neiman Marcus, they’re playfully called Neiman Marcus bars because they’re so outrageously rich (get it?). And if they seem a little familiar, it’s probably because they’re a shortcut version of gooey butter cake from St. Louis, a classic Midwestern dessert. They’re like a cross between buttery, chewy blondies and cheesecake, which means they’re absolutely irresistible. Here’s how to make them.

Why You’ll Love Them

  • They’re ultra-rich and gooey. If you have a sweet tooth, you’ll love these ooey-gooey butter bars. They have a buttery, chewy base topped with a heavenly sweet cream cheese layer.
  • You don’t need any baking skills. Because this recipe relies on boxed cake mix, really anyone can pull them off! The hardest part is waiting for the cream cheese to soften.
  • They yield a lot. Although you only need six ingredients, it makes a big batch of 24 bars. Bring them to your next potluck and watch them disappear.

Nutritional Info


  • 8 ounces

    cream cheese

  • 8 tablespoons

    (1 stick) unsalted butter

  • 1 (15.25-ounce) box

    yellow cake mix

  • 4

    large eggs, divided

  • 1 pound

    powdered sugar (about 4 cups)

  • 1 teaspoon

    vanilla extract


  1. Let 8 ounces cream cheese sit at room temperature until softened. (Alternatively, place the cream cheese in a small microwave-safe bowl, and microwave in 15-second bursts until very soft, 30 to 60 seconds total.)

  2. Arrange a rack in the middle of the oven and heat the oven to 350°F. Line the bottom and the 2 long sides of a 9x13-inch baking pan with a sheet of parchment paper, making sure it is long enough to hang over the sides by at least 1 inch to form a sling.

  3. Place 1 stick unsalted butter in a medium microwave-safe bowl. Microwave in 20-second bursts until melted, 40 to 60 seconds total. (Alternatively, melt the butter in a small saucepan over medium heat and transfer to a medium bowl.) Let cool slightly.

  4. Add 1 (15.25-ounce) box yellow cake mix and 2 of the large eggs to the melted butter. Beat with an electric hand mixer or in a stand mixer with the paddle attachment on medium speed until smooth, 25 to 30 seconds (the batter will be very thick). Transfer to the baking pan and spread into an even layer.

  5. Wipe out the bowl and paddle (no need to wash). Add the cream cheese, remaining 2 large eggs, 1 pound powdered sugar, and 1 teaspoon vanilla extract. Beat with the mixer on medium-low speed until smooth, scraping down the sides once or twice, 40 to 45 seconds total. Pour over the top of the cake batter and spread it into an even layer.

  6. Bake until golden brown around the edges but the center is slightly jiggly when the pan is gently shaken, 35 to 40 minutes. Place on a wire rack and let cool completely, 2 to 3 hours.

  7. Run a thin knife around the edges of the bars to loosen. Grasping the excess parchment paper, lift the slab out of the pan and place on a cutting board. Cut into 24 pieces.

Recipe Notes

Storage: The bars can be refrigerated in an airtight container for up to 1 week. To freeze, wrap in plastic wrap, place in a freezer-safe container, and freeze for up to 4 months. Thaw in the refrigerator for 1 hour or at room temperature for 15 to 20 minutes.
