Preheat oven to 350 degrees F
In a food processor, pulse the cold butter cubes, 2 cups of flour, powdered sugar and a pinch of salt until combined and crumbly.
Press crust mixture into a greased 9x13 baking dish (I like to line mine with parchment paper)
Bake the crust for 20 minutes at 350 degrees F.
While the crust is baking, make your lemon filling. Whisk together eggs, granulated sugar, lemon juice, IPA, 1/4 cup flour and baking powder.
Once the crust has baked for 20 minutes, remove from oven, and pour the lemon filling over the top.
Lay the strawberry slices all over the lemon filling (you can also opt to top with strawberries after the filling bakes).
Bake for an additional 20 minutes at 350 degrees F, or until set in the center.
Remove from oven, and cool completely.
Cut into squares, top with a dusting of powdered sugar, and serve!
