In a bowl, whisk together the egg, sugar, and vanilla extract until smooth.
Add the yogurt and mix until fully combined.
Sift in the all-purpose flour and baking powder, then gently fold until a thick batter forms.
Stir in the grated apple and cinnamon, ensuring even distribution.
Heat a non-stick pan over medium-low heat and lightly grease it.
Drop spoonfuls of batter onto the pan, flattening slightly.
Cook for 2-3 minutes on each side until golden brown and fully cooked through.
Serve warm, optionally dusted with powdered sugar or drizzled with honey.
