Preheat the oven to 350°F (175°C).

Lightly grease the Bundt pan with cooking spray or olive oil.

In a large mixing bowl, combine the tortilla chips, black beans, diced tomatoes, and jalapeños. Toss gently.

Sprinkle half of the shredded cheese over the mixture.

Pour the mixture into the prepared Bundt pan, pressing down slightly to pack it in.

Sprinkle the remaining cheese on top.

Bake in the preheated oven for 25 minutes or until the cheese is bubbly and golden.

Remove from oven and let cool for a few minutes.

Invert onto a serving platter and garnish with sour cream, guacamole, and green onions.
