Step 1

Combine protein powder, almond meal, oat flour, sugar, cinnamon, baking powder, baking soda and salt in a blender; pulse until fully mixed. Add eggs, buttermilk (reduce to 1/2 cup if using whey protein), oil and vanilla; pulse, stopping to scrape down the sides as needed, until combined. Let stand for 15 minutes.

Step 2

Coat a large nonstick skillet or griddle with cooking spray; heat over medium-high heat.

Step 3

Make about 3 pancakes at a time, using 1/4 cup batter per pancake; reduce the heat to medium. Cook until the edges are dry, 1 to 3 minutes. Flip and cook until golden brown on the other side, 1 to 3 minutes more. Repeat with the remaining batter, using more cooking spray and reducing the heat as needed. Serve warm.
