Sugar Cookie Bars - A versatile and delicious sugar cookie bar recipe. Add in any mix-in's you'd like - or leave the bars plain and add a simple frosting. Keep this recipe on hand!

Today’s recipe for Sugar Cookie Bars is one of those recipes to keep on hand as an all-purpose, go-to recipe that can be adapted for many different cookie bar variations! This is a perfectly-sweet sugar cookie bar dough that bakes up soft but still firm enough to cut into bars.

We added Fall-inspired M&M’s (we used the White Chocolate Candy Corn flavored version) and coarsely chopped macadamia nuts here – but you can load your sugar cookie bars up with just about any combination of mix-ins such as nuts, chocolate chips and candies. Just keep the general proportion of about two to three cups of mix-ins to the amount of dough included here in this recipe.

Sugar Cookie Bars - A Family Feast

Sugar Cookie Bars

  • Prep Time: 15 mins
  • Cook Time: 20 mins
  • Total Time: 35 minutes
  • Yield: 16-20 squares depending on how large you cut them


  • 2½ cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup (1 stick) unsalted butter, softened
  • 1 cup granulated sugar
  • 1 egg
  • 1 egg white
  • 2 tablespoons heavy cream
  • 1 teaspoon vanilla extract
  • 1 9.9 ounce bag White Chocolate Candy Corn M&M’s
  • 1 cup macadamia nuts, coarsely chopped


  1. Preheat the oven to 375 degrees. Spray a 13×9” baking dish with non-stick cooking spray and set aside.
  2. In a medium bowl, combine flour, baking powder, and salt. Set aside.
  3. In the bowl of a stand mixer fitted with a paddle attachment, beat butter and sugar for 3 to 4 minutes – until pale and fluffy. Slowly stir in egg, egg white, cream and vanilla and mix until combined.
  4. With the mixer on low speed, slowly add in the dry mixture and mix until completely combined. Fold in the M&M’s and nuts and mix evenly throughout.
  5. Press the mixture into the prepared pan – placing a sheet of plastic wrap over the dough to make it easier to spread the dough without having it stick to your hands.
  6. Bake for 20-25 minutes or until the edges are lightly golden brown (the center should be soft but not uncooked).
  7. Cool completely. Cut into squares.


Adapted from Cooking Classy

If you’d like to frost these sugar cookie bars instead, leave out the candy and nuts before baking. Once cooled, frost the dough with a mixture of ¼ cup butter, 2 cups powdered sugar, 2-3 tablespoons heavy cream, ½ teaspoon vanilla and a pinch of salt. Combine all ingredients – then feel free to add a drop or two of food coloring if desired.
