Top 100 Five-Ingredient Dinners

I didn't have any shortening on hand, so I used an equal amount of unsalted butter (softened). I also used 50-50 all purpose flour and cake flour since I happened to have some on hand. This recipe still worked for me and turned out very light and fluffy and came together so quickly and without any special equipment which I appreciated. I baked in a 9" cake round lined with parchment paper. I think this cake tasted great even on its own, but I served it with lemon curd and lime zest icing for a layered citrus cake. I would definitely use this recipe again for an easy simple dessert!
