Begin by processing the rolled oats in a blender or food processor until they resemble a flour-like consistency.
In a large mixing bowl, combine the oat flour, protein powder, baking powder, and salt. Whisk them together to ensure all dry ingredients are well mixed.
In another bowl, whisk together the buttermilk, egg, honey (or maple syrup), and vanilla extract until combined.
Pour the wet ingredients into the dry mixture. Stir until just combined, then gently fold in the diced strawberries. Avoid overmixing; lumps are okay.
Heat a non-stick skillet or griddle over medium heat and lightly grease it with cooking spray or a touch of butter.
Pour about 1/4 cup of the batter onto the skillet for each pancake. Cook for about 2-3 minutes or until bubbles form on the surface and the edges look set.
Carefully flip the pancakes and cook for an additional 1-2 minutes until golden brown on both sides. Repeat with the remaining batter, adjusting the heat as necessary to avoid burning.
Stack the pancakes on a plate and top with a dollop of Greek yogurt or whipped cream for a creamy finish. Add additional sliced strawberries for garnish if desired.
Notes
Serve pancakes stacked high with a drizzle of honey or maple syrup on top and a scattering of fresh strawberries around the plate for vibrant color.
