A rich, gooey, layered chocolate dessert with buttery caramel and a silky ganache topping. Minimal prep, big flavor — perfect for potlucks, holidays, or a late-night chocolate craving.
1 box chocolate cake mix (approx. 15.25 oz)
2 large eggs
½ cup whole milk
½ cup unsalted butter, melted
1 teaspoon baking powder
¼ cup sour cream
1 cup caramel sauce
½ cup semi-sweet chocolate chunks or chips
½ cup heavy cream
Chocolate shavings
Chopped nuts or toffee bits
Preheat oven to 325°F (163°C). Grease a 9×13-inch baking dish.
In a large bowl, whisk together:
chocolate cake mix
eggs
milk
melted butter
baking powder
sour cream
Mix until smooth.
Pour half the batter into the baking dish.
Warm caramel sauce slightly so it drizzles easily.
Drizzle caramel evenly over the batter.
Gently spoon the remaining batter on top and spread lightly to cover.
Bake 45–50 minutes, or until a toothpick inserted into the center comes out with moist crumbs (no wet batter).
While cake bakes:
Heat heavy cream in the microwave until hot (not boiling).
Add chocolate chunks.
Let sit 1 minute, then stir until smooth and glossy.
Let cake cool for 10 minutes.
Pour warm ganache over the top and spread evenly.
Add toppings (shavings, nuts, toffee) if desired.
Let ganache set 10–15 minutes, then slice and enjoy.
Add a pinch of sea salt to the caramel for salted caramel flavor.
Fold ½–1 cup chocolate chips into the batter for extra richness.
Replace caramel with dulce de leche for a creamier center.
Serve warm with ice cream for a lava cake effect.
