Mix Dry Ingredients: In a bowl, whisk together flour, baking powder, baking soda, and salt. If adding protein powder, mix it in with the dry ingredients.
Mix Wet Ingredients: In another bowl, whisk together milk, egg, melted butter, and vanilla extract.
Combine: Pour the wet ingredients into the dry ingredients and gently mix until combined. Be careful not to overmix; a few lumps are okay.
Fold in Chocolate Chips: Stir in the chocolate chips
Cook the Pancakes: Heat a non-stick skillet or griddle over medium heat. Lightly grease with butter or cooking spray. Scoop about 1/4 cup of batter onto the skillet for each pancake. Cook until bubbles form on the surface, about 2–3 minutes. Flip and cook for another 1–2 minutes or until golden brown.
Serve: Stack the pancakes and top with extra chocolate chips, maple syrup, or fresh fruit.
