These delicate, buttery cookies feature a swirl of zesty lemon and crunchy pistachios, making them a sophisticated gluten-free treat. The dough is rolled with a pistachio-brown sugar filling, chilled, then sliced into rounds for baking. Perfect for dessert or a snack.

I spent a rainy afternoon experimenting with a swirl technique that I was sure would turn into a sticky mess, but the smell of toasted pistachios and lemon zest made the kitchen feel incredibly cozy.

Serving these to my skeptical family members and watching their eyes light up at the first bite was a victory I will not forget.

Ingredients

  • Gluten-Free Flour Blend: Using a blend with xanthan gum is crucial here to mimic the elasticity we miss without gluten.
  • Unsalted Butter: Softening this properly ensures the dough rolls out without cracking later.
  • Lemon Zest and Juice: These provide a bright punch that cuts through the rich butter.
  • Fresh Pistachios: Chopping these finely distributes the nutty flavor evenly in every bite.
  • Light Brown Sugar: This melts into the dough to create that gorgeous caramelized swirl.

Instructions

Mix the Base:
Whisk the dry ingredients in one bowl and cream the butter and sugar in another until the mixture looks pale and airy.
Combine and Chill:
Beat in the egg and vanilla, then slowly mix in the flour blend until a soft dough forms.
Roll and Fill:
Roll the dough into rectangles on parchment, then spread the pistachio butter mixture evenly over the surface.
Create the Log:
Use the parchment paper to help you roll the dough into a tight cylinder and wrap it up.
Chill Thoroughly:
Let the logs rest in the fridge for an hour so they firm up enough to slice cleanly.
Bake to Perfection:
Slice the logs into rounds and bake them until the edges are just turning a light golden color.

These cookies became a staple during the holidays because the green and yellow swirl looked beautiful on a platter.

Getting the Dough Texture Right

Gluten free dough can be temperamental, so do not be afraid to add a sprinkle of water if it feels too dry to hold together.

Toasting the Nuts First

Throw the pistachios in a dry pan for a few minutes before chopping to deepen their flavor profile significantly.

Slicing Success

Keep a damp cloth nearby to wipe your knife blade between slices so they all come out looking picture perfect.

  • Rotate the log a quarter turn after every few slices to keep it round.
  • If the dough cracks, press it back together with your fingers.
  • Chill the scraps in the freezer for a quick baker's snack.

1
Prepare Dry Ingredients: In a medium bowl, whisk together the gluten-free flour, baking powder, and salt. Set aside.

Add Filling: Evenly spread half of the pistachio mixture over each dough rectangle, leaving a 1/2-inch border around the edges.
8
Form Logs: Using the parchment as a guide, carefully roll up each dough rectangle from the long side into a tight log.
9
Chill Dough: Wrap each log in parchment paper and chill in the refrigerator for at least 1 hour, or until firm.
10
Preheat Oven: Preheat the oven to 350°F. Line two baking sheets with parchment paper.
