Hot Chocolate Marble Pound Cake

Transfer about 1/3 of the batter to a medium bowl, and stir in the hot chocolate mix. Spoon 1/2 the remaining vanilla batter into the prepared loaf pan, and smooth over the top with a spatula. Using 1/2 the hot chocolate batter, drop spoonfuls on top of the vanilla batter. Repeat with the remaining vanilla and hot chocolate batters. Run a skewer through the loaf pan to help swirl the 2 batters together. Tap the pan on the counter.
Bake until a toothpick inserted in the center comes out clean and the top springs back when lightly pressed, 1 hour to 1 hour and 30 minutes.
Let the cake cool in the pan for a few minutes, then invert and let cool completely on a rack.
Cook’s Note
For best results, don’t use hot chocolate or cocoa mixes that contain powdered milk or other dairy products, which can change the structure and texture of the cake.
