Step 1

Preheat oven to 350°F. In a medium bowl, combine the flour and powdered sugar. Using a pastry blender cut in butter until the mixture resembles coarse crumbs. Pat the crumbs into a well greased 9 x 13 in baking pan. Bake the crust at for 10-12 minutes or until lightly browned.

Step 2

While the crust is in the oven, mix together eggs, sugar, flour, and salt. Gently stir in the diced rhubarb. Pour the rhubarb mixture over the hot crust.

Step 3

Return bars to the hot oven. Reduce oven temperature to 325° F and bake for 30-35 min or until the filling is set and no longer jiggly.

Step 4

Cool for 30 mins on the counter. Refrigerate and chill completely before cutting into bars.
