Add the chickpeas, remaining corn, tahini, lemon juice, garlic, olive oil, and cumin to a food processor.
Blend until smooth, adding water or chickpea liquid a little at a time until creamy.
Season with salt and adjust the lemon to taste.
Spoon into a bowl, drizzle with olive oil, and top with the reserved corn.
For an elote-style version, char the corn in a dry, hot pan until spotty before blending, then finish the bowl with lime juice, smoked paprika, chopped cilantro, and crumbled vegan feta.
Notes
Grill the corn first for a smoky version. Removing the chickpea skins makes it silkier. Store up to 4 days in the fridge.
