Set the waffle bowls on individual serving plates before filling them.
Divide the yogurt evenly among the four waffle bowls, leaving a little space around the top edge.
Sprinkle the Cheerios evenly over the yogurt so some pieces settle slightly into the surface.
Arrange the sliced strawberries over each bowl.
Finish each bowl with about 1 1/2 teaspoons of mini chocolate chips and a light scattering of rainbow sprinkles.
Serve immediately, preferably within 10 to 15 minutes, so the waffle bowls remain crisp.
