Make the Pistachio Cream Filling
Mix pistachio butter, honey, sea salt, and coconut/oat flour until thick and creamy.
Scoop ½–1 tsp dollops onto parchment.
Freeze 30–40 minutes, until firm and solid.
Make the Cookie Dough
Preheat oven to 350°F and line a baking sheet with parchment.
In a medium bowl, whisk almond flour, protein powder, baking powder, fine sea salt, and 1 tsp coconut flour (or 2–3 tsp oat flour).
In a separate bowl, whisk honey, melted coconut oil, egg, vanilla, and almond extract.
Combine wet and dry ingredients until a soft dough forms.
Fold in chopped pistachios and chocolate chips (if using).
If dough feels sticky, let it rest 5 minutes — the coconut/oat flour will continue absorbing moisture.
Assemble the Cookies- Scoop dough into 8–10 portions.
Flatten each portion to about ½ inch thick.
Place a frozen pistachio filling dollop in the center.
Wrap the dough around it and seal completely.
Press a few extra pistachios or chocolate chips on top.
Chill the assembled cookies 10–15 minutes before baking.
Bake for 9–11 minutes, until edges are set and tops look slightly puffy.
Immediately sprinkle with flaky sea salt.
Let cool 20–30 minutes before lifting or pulling apart.
(Almond‑flour stuffed cookies firm up as they cool.)
