Cut the corn kernels off the cobs. Make sure to scrape the cobs to get the corn milk from the cob.
Place 1 ½ cups of corn and the whole milk into a food processor or blender. Pulse till smooth.
In a rimmed skillet, add 1 tablespoon of butter and the jalapeños. Sauté till tender.
While peppers are cooking, whisk the flour into the heavy cream. Set aside.
Next, add the pureed corn, remaining kernels, remaining butter, and heavy cream mixture to the peppers. Simmer and allow it to thicken and corn to cook. Cook for about 8-10 minutes.
Season with salt and pepper to taste. Allow corn to cool slightly before serving.
