Place basil and garlic in a food processor. Pulse until finely chopped. Add lemon juice, sugar, and salt and process until thoroughly incorporated. Add butter and blend until smooth. Place butter mixture in a small serving bowl or ramekin.
Add corn to large pot of boiling salted water and cook until just tender, about 5 minutes. Transfer to a platter and serve with garlic-basil butter.
