This strawberry rhubarb upside-down cake is a unique twist on the classic cake recipe. The cake is made by layering fresh strawberries and rhubarb on the bottom of a cake pan, then pouring a vanilla cake batter on top. Once baked, the cake is flipped over to reveal a beautiful layer of fruit on top. The secret to this recipe is to use a cast-iron skillet to create a caramelized crust on the fruit. Serve this cake warm with a scoop of vanilla ice cream for a decadent dessert.
