Preheat oven to warm (150 degrees F). Line a large baking sheet with parchment paper.
In a large bowl, whisk together the eggs, Greek yogurt, vanilla extract, and sweetener (if using).
Add the coconut flour and baking soda and whisk until smooth.
Heat a large nonstick skillet over medium-low heat. Spray it with nonstick cooking spray.
Using a 4-tablespoon ice cream scoop or measuring cup, transfer three mounds of the batter into the skillet. Cook the pancakes until bottoms are golden brown, 2-3 minutes.
Carefully flip the pancakes - they're not as sturdy as wheat flour pancakes - and cook until golden and set, 2 more minutes.
Place the cooked pancakes on the prepared baking sheet and keep in the warm oven while you cook more batches.
