Preheat the oven to 170℃ (350°F). Line a baking sheet with parchment paper.
In a medium bowl, combine the almond flour, erythritol, baking powder, and sea salt.
In a small bowl, whisk together the melted coconut oil, orange zest, vanilla, and egg.
Stir the wet mixture into the almond flour mixture, pressing with a spoon or spatula, until a uniform dough forms. (The dough should be pliable and dense, but not crumbly; add a little more coconut oil, a teaspoon at a time, if it’s very dry.)
Stir and press the cranberries into the dough.
Place the dough onto the lined pan and form a disc shape, about 2-3 cm thick and 15 -18 cm in diameter. Cut into 8 wedges, like a pie or pizza. Move the pieces about 2-3 cm apart.
Bake for 18 to 22 minutes, until golden.
Cool completely on the pan to firm up. (Scones will fall apart if you move them before cooling.)
