Preheat your waffle maker according to the manufacturer's instructions.
In a medium bowl, whisk together the pancake mix, oat milk, mashed banana, and sugar until just combined.
Stir in the chocolate chips.
Pour the batter into the waffle maker and cook for 3-5 minutes or until fully cooked.
Serve immediately with your favorite toppings.
Notes
If the batter is too thick, add a little more oat milk.
If the batter is too thin, add a little more pancake mix.
Don't overcook the waffles, or they will become dry.
