Place corn in pressure cooker, add sugar, salt and pepper.
Pour milk over the corn.
Cut the butter and cream cheese into pieces and scatter them over the top of the corn. Do NOT mix.
Secure the lid and turn pressure release knob to a sealed position. Cook at high pressure for 10 minutes.When cooking is complete, use a quick release.
When you remove the lid, the top of the corn may seem curdled. Continue to stir gently and thoroughly, until all of the ingredients come together and form a creamy consistency.
Notes
Let the corn stand for a short time if you prefer the cream to be a little thicker.
