Add eggs, Greek yogurt, almond milk, maple syrup, vanilla extract, oats, baking powder, and cinnamon in a blender. Blend until smooth (~20-40 seconds).
Let the batter sit for 8 minutes while you heat your pan.
Heat a nonstick pan over medium-low heat and lightly oil.
Pour 1/4 to 1/3 cup batter onto the pan, add desired mix-ins, and cook 2-3 minutes until edges set. Flip and cook 1 minute.
Serve immediately with toppings like fruit, syrup, or nut butter.
