This classic caramel cake recipe is a simple yet delicious dessert that is perfect for any occasion. The cake is made with a moist and fluffy vanilla sponge that is layered with a rich and creamy caramel frosting. The frosting is made with butter, brown sugar, heavy cream, and vanilla extract, which gives it a smooth and velvety texture. The cake is then topped with a drizzle of caramel sauce and a sprinkle of sea salt for an extra touch of sweetness and flavor.
