Preheat oven to 375 degrees Fahrenheit. Line a baking sheet with parchment paper or a silicone mat. Set aside.
Add the coconut oil and the pure maple syrup to a large bowl. If the oil is very hard, microwave for a few seconds until soft but not melted. Stir briskly with a whisk until the syrup and oil are mixed together - this may take a minute or two. Add the egg and vanilla and whisk together until combined.
In a medium bowl, stir together the almond flour, baking soda, and salt. Add the flour mixture to the wet ingredients and stir together with a wooden spoon until combined. Stir in 1/2 cup chocolate chips.
Scoop mounded tablespoonfuls onto the cookie sheet, spacing about two inches apart. Press down gently with your fingers to flatten slightly. Top each with a few additional chocolate chips, if desired.
Bake until set and the edges are golden brown, 8-9 minutes. Remove from oven and let cool for about 5 minutes, then transfer to a wire rack to cool completely.
Cookies keep well in an airtight container at room temperature for 4-5 days.
