Step 1

Pre-heat oven to 350F (180C). Lightly grease and flour an 8x8 inch (20x20cm) square cake pan or line with parchment paper.

Step 2

In a medium bowl, beat on medium speed the butter and powdered sugar until combined then add the flour and beat again until a soft dough forms (approximately 1 1/2 minutes). Pat evenly onto the bottom of the prepared baking pan. Bake 18-20 minutes. Remove from oven, but leave oven on.

Step 3

Meanwhile in a medium bowl, beat together, the eggs, granulated sugar, baking powder, fresh lemon juice, pinch of salt and zest. Pour over warm v (not hot) baked base and return to the oven for 20-25 minutes (until the centre is set, I baked mine for 25 minutes, may need to go a bit longer), Cool in the pan, I recommend that you also chill in the fridge for 1 hour for easier cutting, cut into squares, remove from pan, dust with powdered sugar and serve. Enjoy!
