Lightly toast the sesame seeds in a large skillet over medium heat, taking care not to burn them, 2 to 3 minutes. Transfer to a small bowl and reserve.
Return the skillet to medium heat and add the butter and garlic. Saute the garlic as the butter melts, about 2 minutes. Add the corn, salt and pepper to taste. Cook until the corn is just tender and warmed through, about 5 minutes. Turn off the heat and add the sesame seeds and half the basil and mix until combined. Transfer to a serving bowl and garnish with the remaining basil.
