Preheat your oven to 350°F. Spread the tortilla chips in a single layer on a large baking sheet.
Bake the chips for about 5 minutes, just until they are warm and slightly crispy. Remove from the oven and let cool slightly.
Drizzle the vanilla frosting over the warm tortilla chips, using a spoon or a piping bag for a fun design.
Sprinkle the rainbow sprinkles and mini chocolate chips evenly over the frosted chips.
Top the nachos with sliced bananas and strawberries.
Drizzle chocolate sauce and caramel sauce generously over the entire dish.
Add dollops of whipped cream on top for an extra treat.
Serve immediately and enjoy your delicious dessert nachos!
