In a large mixing bowl, mash the ripe bananas with a fork until smooth. Add in the eggs, melted butter, milk, and vanilla extract. Mix until everything is well combined.
In another bowl, whisk together the wholemeal flour, white flour, sweetener, baking powder, and a pinch of salt.
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined.
Gently fold in the chocolate chips, ensuring they are evenly distributed throughout the batter.
Preheat your non-stick skillet or griddle over medium heat. If necessary, lightly grease it with a bit of oil or cooking spray.
Pour about 1/4 cup of batter onto the skillet for each pancake. Cook until bubbles form on the surface and the edges look set, then flip and cook for another 1-2 minutes until golden brown.
Serve your pancakes warm with your favorite toppings such as maple syrup, fresh fruit, or additional chocolate chips.
