Healthy Vanilla Cake with Chocolate Fudge Frosting

"This 5-ingredient party-perfect vanilla cake recipe is healthy disguised as decadent underneath a luscious layer of sugar-free chocolate fudge frosting! The cake itself is made with just 5 simple ingredients and right in the blender too. No flour necessary as rolled oats ground until fine make up the dry ingredients instead. Medjool dates take the place of sugar and keep the cake really moist too. After baking this beautiful fluffy vanilla cake comes my favorite part--the frosting! Thick, rich, and fudgy as can be. But secretly healthy too!"
