Double Chocolate Whole Wheat Pancakes

0 In a large mixing bowl, whisk together eggs, sugar, cooking oil, and buttermilk. 
1 Add whole wheat flour, cocoa powder, baking powder, and salt and stir just until combined. 
2 Fold in chocolate chips.
3 Ladle batter into an oiled griddle or skillet at low medium heat until bubbles form on the surface. Flip and cook on the other side until set. (Note: keep the heat lower than you would with other pancakes because the slightly higher sugar content in these can burn more easily.)
4 Serve immediately with butter and maple syrup on top.
