Perfect Vanilla Chai Sugar Cookie Bars

Cookie Bars – Soft and buttery, the sugar cookie bars feature my favorite blend of chai spices. Cornstarch gives the cookie bars an ultra soft, melt-in-your-mouth texture.

To make the cookie bars, whisk together flour, cornstarch, baking powder, baking soda, salt, and spices in a small bowl. Beat butter and sugar in a large mixer bowl at medium speed until creamy. Beat in egg and vanilla until combined. Reduce speed to low and gradually add flour mixture; beat just until incorporated.

Bake Bars – Scrape dough into an an 8-inch square metal baking pan lined with parchment paper. Use a piece of wax paper lightly coated with nonstick spray to press dough evenly into pan. Bake bars at 350°F for 22 to 24 minutes, until edges are golden, top is set, and a toothpick inserted in the center comes out clean. Cool completely in baking pan on a wire rack.

Frosting – The vanilla frosting is sweet, creamy, and delicious! Vanilla extract or vanilla bean paste both work beautifully here.

To make the frosting, beat butter and salt in a large mixer bowl on medium speed until smooth. Beat in vanilla. Reduce speed to low and beat in powdered sugar until incorporated. Add milk and mix on low speed until combined, then beat on medium speed for 1 minute, until light and airy.

Assemble – One the cookie bars are completely cool, use an offset spatula to swirl vanilla frosting over the top. Top with holiday sprinkles and chill for 15 minutes to let the frosting set before cutting into bars.

Baking for a Crowd

If you’re hosting a group for the holidays or making treats for a cookie swap, this recipe easily doubles for a 13 x 9-inch baking pan. Simply double the ingredients and bake as directed (the baking time will remain the same). Let the bars cool completely, top with frosting, and enjoy!

  • 1/4 tsp salt
  • 1 tsp cinnamon
  • 1/2 tsp ground ginger
  • 1/4 tsp cardamom
  • 1/4 tsp cloves
  • 1/4 tsp nutmeg

Instructions

  1. Preheat oven to 350°F and line an 8-inch square metal baking pan with parchment paper.

  4. For the frosting, beat butter and salt in a large mixer bowl on medium speed until smooth. Beat in vanilla. Reduce speed to low and beat in powdered sugar until incorporated. Add milk and mix on low speed until combined, then beat on medium speed for 1 minute, until light and airy.

  1. These were easy to make and delicious to eat! I doubled the recipe for the bars but only made enough frosting for one recipe and it was perfect. I used a 9×13 glass pan so dropped the oven temp down by 25 degrees, the edges were firm but not over done. I will definitely make them again! Thanks!






    1. Hi Ellie! The baking time may be slightly longer in a ceramic pan, so just keep an eye on the bars. Happy baking! 🙂

  2. I’m running short on time to bake holiday goodies for my friends! These marvelous, festive cookie bars are perfect!!!






  3. Oh my, these cookie bars are so glorious and incredibly stylish as well as sounding delicious. Cheers and Merry Christmas, Ardith
