Chocolate Hazlenut Swirl Cake

Chocolate and hazelnuts are a match made in heaven. This moist adaptation of Hershey’s Perfectly Chocolate chocolate cake has chocolate ganache and hazelnuts swirled inside. There are many ways to add the ganache: as a layer in between 2 round cakes, drizzle it over a bundt cake, use it as a layer of “frosting” on top, or swirl it in with a butterknife like in this recipe. This ganache-hazelnut mixture has egg, so it needs to be baked with the cake. Note: This recipe makes enough for one 9-inch round cake; double if layering for 2 rounds.
