Three layers of moist and fudgy chocolate sponge, creamy tahini chocolate buttercream, and delicious tahini caramel make up this decadent cake. My Chocolate Tahini Caramel Cake is not only egg-free and dairy-free, but it’s also super simple to make! The sponge is made in just one bowl, starting with buttermilk for a soft, tender crumb. Tahini adds moisture and a subtle nutty flavor that pairs perfectly with the rich chocolate. The buttercream is smooth and creamy, and each layer is filled with my three-ingredient gooey tahini caramel. This is the ultimate chocolate cake for all chocolate lovers.
