These lemon bars with lemon curd are delicious with tangy lemon curd and crunchy crust!
Preheat the oven to 350°F(177C°). Grease 8 inch (20cm) square oven-proof dish and line the bottom and sides with parchment paper, about 2 inches(5 cm) of overhang on each side.
Spread the mixture into the oven proof dish with your hand. You can use back of a spoon to spread it evenly. You should lightly flour the spoon to avoid it sticking to the flour-butter mixture. Bake almost 25 minutes until it is golden brown. For a soft crust: Bake for 20 minutes or until it lightly changes color.
Filling: Mix the lemon zest and sugar in a bowl with a fork or rub with your fingertips to increase the lemon flavor. Add in the eggs and whisk for almost 30 seconds until combined well. Then add the cooled melted butter, lemon juice and mix. Add the flour until combined well.
After 25 minutes (or almost 20 minutes for a soft crust), remove the dish from the oven and add the filling. Bake for 12 minutes until the filling is set but still soft. Remove the dish from the oven and let it cool at room temperature for almost 1,5 hours. When it is cool enough, lift the paper from the sides. Cut into 9 or 16 squares. Dust with powdered sugar.
