In an electric mixing bowl (or food processor)fitted with a paddle attachment, whisk the room temperature cream cheese.
While the cream cheese is still whisking, add the rest of the ingredients except the sharp cheddar shreds. Mix the ingredients thoroughly while scraping down the sides of the bowl every few seconds to make sure the cream cheese.
Add the shredded sharp cheddar and whisk in briefly to mix in. If the mixture is too wet, add additional cheese to firm up. Adjust the final seasoning with salt, if needed.
Notes
You can make this by hand with soft room-temperature cream cheese. It's just more accessible using a food processor or electric mixer.
