Place the chickpeas in a food processor and pulse into a fine, breadcrumb-like texture, scraping down the sides as needed, about 15 seconds total.
Add the lemon juice, yogurt, garlic, salt, cumin, and ice cubes. Blend until completely smooth, about 5 minutes, stopping to scrape down the food processor as needed. While the food processor is running, drizzle in the olive oil. Taste the hummus and adjust the flavor as needed by adding more lemon juice or salt.
Spread the hummus onto a plate or into a bowl, sweeping the hummus with the back of a spoon to create swirls for catching the olive oil. Drizzle the hummus with olive oil and then sprinkle it with cumin and fresh parsley. Serve cool or at room temperature.
