Gluten-Free Pistachio Date Cookie Slices with Rice Flour

These tender, buttery cookie slices combine sweet chopped dates with crunchy salted pistachios in a gluten-free pastry made from rice flour and tapioca starch. The naturally sweetened filling is sandwiched between two layers of delicate dough, then baked until golden brown. Perfect for afternoon tea, dessert buffets, or as a sweet treat for those avoiding gluten. The optional honey glaze adds extra shine and sweetness, while the rice flour creates a surprisingly tender texture that rivals traditional wheat-based pastries.

FAQ
Can I make these without xanthan gum?
Yes, but the texture will be more crumbly. Add an extra 2 tablespoons rice flour to help bind the dough together.
How long do these keep?
Store covered at room temperature for 3 days or refrigerate for up to 1 week. They can also be frozen for up to 3 months.
Can I substitute other nuts for pistachios?
Absolutely! Chopped almonds, walnuts, or pecans work well. Use the same amount and ensure they're chopped to similar size.
