MJF: Made 11/17/22. Awesome. I didnt dust with powdered sugar. Actually liked better seeing raspberries more clearly. Next day...crust got soggy. Compare crusts with others to fix

For crust, beat butter with an electric mixer on medium speed for 30 seconds. Add the powdered sugar and orange zest. Beat until combined, scraping sides of the bowl occasionally. Add the flour; beat until combined. Press mixture into the bottom of a greased 8x8 or 9x9 baking pan. Bake in a 350 degree F oven for 20 minutes or until golden.

Meanwhile, for filling, combine eggs, vanilla, granulated sugar, lemon juice, orange peel, flour, and baking powder in a large mixing bowl. Beat for 2 minutes with an electric mixer until combined. Sprinkle berries over crust. Pour filling over berries, arranging berries evenly with a spoon.

Bake in a 350 degree F oven for 30 to 35 minutes or until light brown and filling is set. Cool in pan on a wire rack. Cut into bars. Just before serving, sprinkle with powdered sugar.

Make-Ahead Tip: Cover and store in the refrigerator up to 2 days. Or, place cut bars in a storage container or freezer bag and freeze up to 1 month. Thaw, covered, in the refrigerator.
