In a large mixing bowl, whisk together the gluten-free self-raising flour, gluten-free baking powder, and caster sugar.
In a jug, beat together the eggs and milk until well combined.
Make a well in the center of the dry ingredients and gradually pour in most of the wet mixture while whisking until smooth.
The batter should be thick yet pourable. If needed, add the remaining milk mixture until you reach the right consistency.
Heat a lightly greased frying pan over medium-low heat.
Spoon about 2 tablespoons of batter into the pan for each Gluten-Free Fluffy American Pancake.
Cook for 1–2 minutes until bubbles appear and the surface begins to set.
Flip carefully and cook for another 30–60 seconds until golden.
Repeat with the remaining batter, lightly greasing the pan between batches.
Serve warm with maple syrup and your favorite toppings.
