Low-FODMAP Sugar Cookie Bars with Buttercream Frosting; Gluten-free

Print Friendly Version

This is a recipe that called to me.

At night when I slept I could hear a voice calling out ‘sugar cookie bars, Rachel’.  You know you must have me!

And they were absolutely right.  This recipe for low-FODMAP Sugar Cookie Bars will be an instant sensation in your life too 🙂

I’m always a sucker for pink frosting, rainbow sprinkles, and a sugary cookie chewy base with a hint of almond flavoring. The flavor combination seems like it’s made in heaven.

Low-FODMAP and gluten-free sugar cookie bars are beautiful and joyous on any table. These would be perfect at a child’s birthday party, baby shower, holiday feast, or ‘just because’.

You can jazz them up for Halloween with orange frosting and black sprinkles, celebrate Christmas time with green and red themes, or make it a Valentine‘s treat with red hearts and glitter.

  • 1 & 1/2 cups confectioner’s sugar
  • 1/2 cup unsalted butter, softened

  • A few drops of food coloring, optional
  • Non-pareils or sprinkles, gluten-free, for decorating, optional

Directions

  • Pre-heat oven to 350°F and prepare your line 9-inch square baking pan with parchment paper, leaving a 1 inch overhang. Spray with baking spray or grease with shortening

  • Add the dry ingredients and mix until combined, scraping the bowl as needed
  • Fold in the sprinkles by hand
  • Transfer the dough to your prepared pan and spread with your spatula.  It will be thick
  • Bake for 22-25 minutes until a tester is just done with moist crumbs. Do not overbake the bars, as you want them to remain soft
  • Cool in the pan on a wire rack before frosting
  • While cooking, prepare the frosting
    • In your stand mixer with flat paddle, beat 1/2 cup butter
    • Slowly add confectioner’s sugar, then salt on low speed
    • Increase speed to medium and beat for 3 minutes until light and fluffy
    • Add vanilla and LF milk or cream until consistency is as desired
    • Add optional food coloring and beat again
    • Place in a piping bag or use an angled spatula to spread over bars
