In a medium bowl, beat the egg with Greek yogurt, honey and coconut oil until smooth.
Combine flour and baking powder in a separate bowl.
Pour the wet ingredients into the dry ingredients, then whisk while pouring in the milk. Start with about 3 tablespoons of milk and, if necessary, add more until you get a smooth pancake batter.
Let the mini pancake batter rest for at least 5 minutes.
Preheat a large non-stick skillet over medium heat. If using a normal skillet, lightly grease it with cooking spray or a small amount of oil.
Once the skillet is hot, use a tablespoon or a small ice cream scoop to drop small portions of batter onto the cooking surface. Cook mini pancakes over medium heat until the underside is golden and bubbles begin to appear on the surface, then flip and cook on the other side.
