Step 1: Preheat oven: Set oven to 180°C/350°F and line your pan with parchment paper.
Step 2: Make the base: Blend flour, rice flour, sugar, salt, and butter until crumbly like sand.
Step 3: Press into pan: Pour mixture into the pan and press firmly into an even layer.
Step 4: Bake base: Bake for 20 minutes until lightly golden. Don’t let it cool after.
Step 5: Make lemon topping: While base bakes, whisk eggs, sugar, flour, lemon zest, and juice until smooth.
Step 6: Pour immediately: Pour lemon mixture over the hot base right out of the oven.
Step 7: Bake again: Bake for another 20 minutes until the top is set but still slightly soft.
Step 8: Cool down: Let it cool at room temp for 1 hour, then chill in the fridge for at least 2 hours.
Step 9: Slice and serve: Cut into squares and dust with powdered sugar if you want that classic look.
