Preheat oven to 350°F and line a baking sheet with parchment paper.
Rinse and drain the black beans thoroughly, then pat them dry with a paper towel.
Place the black beans, almond butter, olive oil, honey, and vanilla extract into a food processor.
Blend until the mixture is completely smooth and no bean skins are visible.
Add the almond powder, whey protein isolate, cacao powder, baking powder, and sea salt to the processor.
Pulse until just combined into a thick, sticky dough.
Use a tablespoon to scoop the dough into 25 small mounds on the prepared baking sheet.
Flatten each mound slightly with the back of a spoon or damp fingers.
Bake for 12 to 15 minutes until the edges are set but the centers remain soft.
Allow the cookies to cool completely on the baking sheet to firm up before serving.
