In a medium size sauce pan over medium heat, melt the butter. Add the flour, while continuously stirring, until flour becomes fragrant and starts to turn lightly tan in color.

Step 2

Keep stirring while slowly pouring in the milk. Continue to stir/whisk to remove any lumps. Add onion powder, salt and cayenne.

Step 3

Once sauce begins to thicken, add the cheese and continue stirring until cheese is melted and blended. Remove from heat and serve immediately.
