Place the rinsed black beans, cilantro, lime juice, olive oil, minced garlic, cumin, salt, and chili powder into the bowl of a food processor.

Pulse the mixture 5 to 10 times to break down the beans.

Process on high for 1 minute until the texture is smooth and uniform.

Add water 1 tablespoon at a time while the processor is running if a thinner consistency is required.

Transfer the dip to a serving bowl and garnish with additional cilantro.

Serve immediately at room temperature or refrigerate in an airtight container.
