Heat the kernels along with the butter, green onions, hot peppers, garlic and cream in a medium skillet until warmed through and the cream has reduced.
Transfer to a food processor (or use a stick blender right in the pan) and pulse a couple times to turn the corn mixture into a coarse paste. You should be able to see whole kernels of corn.
Season to taste with salt, pepper and a squeeze of lemon juice
Butter all of the bread slices on one side.
Arrange four slices, unbuttered side up, and divide the corn mixture between them. Spread to the sides. Top with the cheese and cover with the remaining slices of bread.
Grill on a panini press until golden brown.
