01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large bowl, whisk together whole wheat flour, almond flour, protein powder, baking powder, sea salt, and black pepper until well combined.
03 - In a separate bowl, beat eggs, Greek yogurt, milk, and oil until smooth and uniform in texture.
04 - Pour wet mixture into dry ingredients. Stir until just combined, being careful not to over-mix as this can toughen the biscuits.
05 - Gently fold in shredded cheddar cheese if using, distributing evenly throughout the dough.
06 - Scoop 8 equal portions onto the prepared baking sheet, shaping gently into rounds with your hands or a spoon.
07 - Bake for 16–18 minutes until golden brown on top and firm to the touch when lightly pressed.
08 - Let biscuits cool on the baking sheet for 5 minutes before serving. Store leftovers in an airtight container.
