Prep the oven and pan: Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
Combine dry ingredients: In a bowl, whisk 1 1/2 cups unsweetened shredded coconut, 3/4 cup fine almond flour, 1/2 cup granulated keto sweetener, 1 teaspoon baking powder, and 1/4 teaspoon fine sea salt.
Mix the wet ingredients: In a small bowl, whisk 1 large egg, 1/3 cup melted butter (slightly cooled), and 1 teaspoon vanilla extract until smooth.
Bring the dough together: Pour the wet mixture into the dry ingredients. Stir with a spatula until a thick, sticky dough forms.
If it looks dry, add 1–2 teaspoons of water. If too wet, sprinkle in a bit more almond flour.
Portion the cookies: Scoop tablespoon-sized mounds (about 1 heaping tablespoon each) onto the prepared sheet. Space them about 2 inches apart.
Flatten slightly: Lightly press each mound with your fingertips to about 1/2 inch thick.
For defined edges, smooth the sides a bit as you press.
Bake: Bake 10–12 minutes, until the edges turn light golden brown. The centers should look set but still soft.
Cool on the pan: Let the cookies rest on the baking sheet for 10 minutes. They firm up as they cool.
Finish cooling: Transfer to a rack and cool completely for best texture.
Enjoy once they reach room temperature.
