Preheat your oven to 350°F (175°C) and line a large baking sheet with parchment paper.
Rinse the black beans thoroughly in a colander and pat them completely dry with a paper towel to ensure the proper cookie texture.
Place the dried black beans, almond butter, olive oil, honey, and vanilla extract into a food processor.
Process the mixture on high until it is completely smooth and creamy, scraping down the sides as needed.
Add the whey protein isolate, almond flour, cacao powder, baking powder, and sea salt to the processor.
Pulse the ingredients until just combined into a thick, sticky dough, being careful not to over-process.
Using a small spoon, scoop the dough into 25 tiny mounds on the prepared baking sheet.
Lightly press down on each mound with a damp finger or the back of a spoon to flatten them slightly.
Bake for 9 to 11 minutes until the cookies are set on the edges but still feel soft in the center.
Remove from the oven and allow the cookies to cool completely on the baking sheet to firm up before eating.
