Add your whipped butter and frozen corn kernels directly into a small saucepan set over medium heat. There's no need to thaw the corn beforehand since it will defrost naturally as it cooks. Stir occasionally so the butter coats the kernels evenly instead of pooling at the bottom.
Let the corn cook for about 6 to 8 minutes, stirring every minute or so. You'll know it's ready when the kernels look plump, bright, and fully thawed with no icy bits left. This step is really about patience more than technique, so don't rush it.
Once the corn is fully defrosted and warmed through, pour in the honey and sprinkle in the kosher salt and black pepper. Stir everything together well so the honey melts into the butter and forms a light glaze over every kernel.
Let the mixture simmer for another minute or two so the honey and butter reduce slightly into a glossy sauce. Keep stirring gently during this stage so nothing sticks or scorches on the bottom of the pan. The corn should look shiny and coated by the time you're done.
Take the pan off the heat and transfer the corn to a serving bowl right away. This dish tastes best served hot, while the honey butter sauce is still warm and pourable. Waiting too long will cause the sauce to thicken up and lose some of its silky texture.
