In a large mixing bowl, whisk together the white whole wheat flour, oats, brown sugar, baking powder, baking soda, and salt.
In a separate bowl, beat the egg and then add the vanilla extract, buttermilk, and canola oil. Whisk until well combined.
Pour the wet ingredients into the bowl with the dry ingredients. Gently fold them together until just combined.
Fold in the chocolate chips to the pancake batter.
Heat your griddle or frying pan over medium heat.
Pour about 1/4 cup of batter onto the hot griddle for each pancake. Cook until bubbles form, about 2-3 minutes, then flip and cook until golden brown.
Stack your pancakes on a plate and serve warm with your favorite toppings.
