Combine sugar and melted butter in a bowl. Whisk until well combined.
Add the eggs and egg yolk to the bowl. Whisk until combined.
Add milk, vanilla extract, lemon juice, zest of 1 lemon, ricotta cheese, and salt. Mix until combined.
Lastly, add in the sweet rice flour and baking powder. Mix until a thick batter forms.
Heat some butter over medium low heat. Make sure to use a nonstick pan. Don't be afraid to lower the heat if the pan looks like it's getting too hot.
Use a 1/3 cup measuring cup to spoon the batter into the center of the pan. Move the measuring cup in a circular motion to get the circular disk shape.
Cook for 2 minutes until bubbles start to appear. Flip and cook another 2 minutes.
Transfer to a plate and repeat the process with the rest of the batter.
Top the pancakes with fresh fruit, butter, and a drizzle of maple syrup.
