Heat a skillet over medium heat and cook ground beef until browned.
Add chili powder, cumin, paprika, garlic powder, salt, and pepper to the beef and mix well.
Add water and simmer for 2–3 minutes, then set beef aside.
Preheat oven to 400°F (200°C).
Spread tortilla chips evenly on a large oven-safe plate or tray.
Scatter cooked beef, black beans, corn, and shredded cheese over the chips.
Bake for 8–10 minutes until cheese is melted and bubbly.
Remove from oven and add diced tomatoes, jalapeños, and sliced red onions.
Drizzle sour cream and guacamole over the top and finish with chopped cilantro.
Serve the nachos stacked high with visible layers for a bold presentation.
