Fluffy, Flavor-Packed Protein Pancakes

Whisk together flour, protein powder, sugar, baking powder, baking soda, salt, and cinnamon (if using) in a large bowl.

In a separate bowl, whisk together buttermilk, egg yolks, melted butter, and vanilla extract.

In a clean, dry bowl, beat egg whites until stiff peaks form.

Gently pour the wet ingredients into the dry ingredients and whisk until just combined. Do not overmix.

Gently fold the whipped egg whites into the batter in two additions, being careful not to deflate them.

Heat a lightly oiled griddle or frying pan over medium heat. Drop 1/4 cup of batter onto the hot surface for each pancake.

Cook for 2-3 minutes per side, or until golden brown and cooked through. Watch for bubbles forming on the surface.

Serve hot with your favorite toppings.
