Add all ingredients to a high-powered blender and blend until completely smooth and creamy, about 2-3 minutes. Add additional salt, to taste.
NOTE: If you want a thinner consistency for the Queso, add additional milk.
You can either add the Queso to a saucepan over medium-high heat, stirring it until it begins to bubble----to serve it warm or serve it immediately after it's blended.
To serve, add to a bowl and top with salsa (gently spreading it atop the Queso in a circular motion), sliced jalapeños, and chopped cilantro. Enjoy with your favorite tortilla chips, over nachos, burrito bowls, in quesadillas, etc.
