Whole Wheat Buttermilk Pancakes

Combine buttermilk, egg, and vegetable oil in a bowl. Mix in flours, baking powder, baking soda, and salt. Stir in chocolate chips.

Spray a skillet with cooking spray and heat over medium heat. Working in batches, spoon or pour 1/4 cupfuls of batter onto the hot skillet. Cook until bubbles form and edges are dry, 2 to 3 minutes. Flip and cook until golden brown, about 2 minutes longer.
