Awaken the Liquids: In a large mixing bowl, combine the whole egg, egg whites, low-fat buttermilk, 1 tablespoon of maple syrup, avocado oil, and vanilla extract. Whisk gently until the mixture is uniform in color and consistency.
Sift the Powders: In a separate medium bowl, add the white whole wheat flour, vanilla protein powder, low-sodium baking powder, cinnamon, and nutmeg. Use a whisk to thoroughly combine the dry ingredients and break up any clumps in the protein powder.
Marry the Mixtures: Pour the dry powder mixture into the bowl with the wet ingredients. Using a silicone spatula, fold the ingredients together until just moistened. Do not overmix; a few small lumps in the batter are expected and help keep the texture light.
Hydrate the Batter: Set the prepared batter aside, uncovered, for 8 minutes. This resting period allows the whole wheat flour and protein powder to fully absorb the liquids, resulting in a thicker, more tender pancake.
Prepare the Cooking Surface: While the batter rests, place a large, heavy-bottomed skillet over medium-low heat. Add a very thin layer of avocado oil, wiping out any excess with a paper towel. The surface is ready when a drop of water sizzles and evaporates on contact (approx. 350°F / 175°C).
Cook the Pancakes: Using a ¼-cup measure, pour the batter onto the preheated skillet to form rounds, leaving space between each. Cook for 2 to 3 minutes on the first side, or until bubbles appear across the surface and the edges look dry and matte.
The Final Flip: Carefully slide a thin spatula underneath each pancake and flip. Cook the second side for an additional 60 to 90 seconds, just until cooked through and golden brown. Transfer to a plate and repeat with the remaining batter.
Plate and Serve: Serve immediately while warm. Top with fresh berries and a small dollop of almond butter or a minimal drizzle of syrup if desired.
