Make an angel food cake according to the box. I know, I cheat! I'm sorry, but I'm only human.
1/3 c. lemon juice, FRESH
2 c. powdered sugar
2 tbs. butter, melted
1 tbs water
Pop the cake out of the pan. Pour, spoon, brush (whatever method you prefer) the glaze onto the cake.
Notice the pooling of glaze around the cake on the plate... Yum!
-I will admit, the fresh lemon juice was very lemony. But it was good.
