For the Crust

1½ cups gluten free flour 222g
½ cup granulated sugar 100g
½ cup salted butter 113g, cold and cut into pieces (1 stick), dairy-free butter works well
2 tbsp water 28 ml

For the Filling

1½ cups granulated sugar 300g
½ cup lemon juice* 118ml (from 4 lemons, Meyer lemons provide a sweeter flavor)
2 tbsp grated lemon zest* 12g (from 2 lemons), add extra zest for a stronger lemon flavor
4 large eggs lightly beaten
¼ cup gluten free flour 37g

For Serving

powdered sugar** optional

Instructions

For the Crust

Preheat oven to 350°F. Spray a 9x9-inch baking pan with nonstick spray and set aside. (I also like to line with foil and then spray. It makes pulling them out of the pan much easier.)
In a medium bowl, combine the flour and sugar. Use a fork or knivesto stir in the butter until a crumbly mixture results. Add the water a bit at a time. Take mixture and press evenly into the bottom of the pan.

Bake for approximately 25 minutes until slightly golden and set.

For the Filling

In a large bowl, stir together all of the filling ingredients until smooth.
1½ cups granulated sugar, ½ cup lemon juice*, 2 tbsp grated lemon zest*, 4 large eggs, ¼ cup gluten free flour
Pour mixture over the still-hot crust.
Bake 22-26 minutes, or until set in the middle. Let cool on the counter for a minimum of 2 hours. Cut into squares and sprinkle with powdered sugar.

Notes

*On average, one lemon has 2 tbsp lemon juice and 1 tbsp lemon zest.

**Powdered sugar is gluten-free as long as it uses cornstarch or tapioca starch as its base. Be sure to double-check the ingredient list.
