Preheat your oven to 350°F (175°C).
Line a baking sheet with parchment paper.
In a large bowl, whisk the almond butter, coconut sugar, maple syrup, egg, and vanilla until smooth and glossy.
Add almond flour, protein powder, baking soda, and salt. Stir with a spatula until a thick dough forms. If the dough looks crumbly, add 1 tablespoon of milk and fold again.
Add the second tablespoon only if needed.
Fold in the chocolate chips, reserving a few for pressing on top.
Scoop heaping tablespoons of dough onto the baking sheet, spacing about 2 inches apart. Gently press each mound to about 3/4-inch thick. Press extra chips on top for that bakery look.
Bake for 8–10 minutes, until the edges are set and the centers look slightly soft. Do not overbake.
Cool on the sheet for 5 minutes, then transfer to a rack to cool fully.
Sprinkle with flaky sea salt while warm if you like.
