These grain-free thumbprint cookies feature a soft almond flour base filled with a naturally sweet pistachio-date mixture inspired by the ancient Mesopotamian treat, Mersu. SCD-friendly and refined sugar-free, they’re perfect for gut-friendly snacking or a wholesome dessert.
Mix almond flour, coconut flour, baking soda, and salt in a bowl.
Beat butter, honey, vanilla, and eggs in a separate bowl.

Fill cups with pistachio-date filling

Bake for 15 - 18 minutes until cookies are slightly browned on top and slightly firm to the touch
Cool on baking sheet for 10 - 15 minutes until the cookies firm up enough to be transferred to wire rack
Cool the rest of the way on wire rack
Add pistachios and dates to food processor
Process until the mixture clumps together
It's okay if it's a little crumbly, but you should be able to easily press it together to form balls without it falling apart

If you are going to eat right away, storing in the fridge is best as the pistachio-date filling will get hard in the freezer. Sore in the fridge for up to one week. Store in the freezer for longer-term for up to four months.
Use the leftover filling for raw pistachio-date energy balls.
