Follow these straightforward steps to whip up a batch of this delicious dip:

1. Place a medium saucepan over medium heat and add the cubed Velveeta cheese.
2. Pour in the Rotel tomatoes with their juices, and stir occasionally until the cheese begins to melt.
3. Add the ranch seasoning mix, milk, garlic powder, and cayenne pepper. Stir well to combine.
4. Continue to cook, stirring frequently, until the mixture is smooth and the cheese is fully melted, about 8-10 minutes.
5. Once everything is melted and mixed, taste and adjust the seasoning if necessary.
6. Transfer the queso to a serving bowl and sprinkle with chopped cilantro for a fresh touch.
7. Serve immediately with tortilla chips, fresh veggies, or even over nachos.

From my own experience, I recommend tasting as you go and adjusting the spices to suit your palate. My grandmother always said cooking is all about balance, and that wisdom guides me in every recipe I create.
