Pour the milk into a saucepan and warm it over medium heat until it just starts to simmer, filling your kitchen with a gentle warmth and a subtle aroma.
Add the cream cheese to the warm milk, stirring constantly with a whisk until the mixture is smooth and creamy, with no visible lumps.
Stir in the shredded cheddar cheese gradually, allowing each addition to melt completely before adding more, resulting in a glossy, thickened sauce.
Mix in the chopped smoked jalapeños, distributing their smoky heat evenly throughout the queso.
Sprinkle in the ground cumin, paprika, and garlic powder, stirring well until fragrant and fully incorporated into the smooth sauce.
Allow the mixture to simmer gently for 3-5 minutes, stirring periodically, until thickened and heated through, with the aroma of spices filling the air.
Taste the queso and season with salt and black pepper as needed to balance the flavors, stirring to combine well.
Remove from heat and transfer to a serving bowl, or keep warm in the saucepan for instant dipping.
Serve immediately with tortilla chips, vegetables, or your favorite dippable snacks, enjoying the creamy, smoky, spicy flavor.
