A rich, moist chocolate “Earthquake Cake” made with boxed cake mix, sour cream, and chocolate chips — an easy, comforting dessert that’s perfect for a cozy night or family gathering.

  • Total Time: about 50 minutes
  • Yield: 8–10 servings

Ingredients

  • 1 box chocolate cake mix
  • 1 cup sour cream
  • 1/2 cup semi‑sweet chocolate chips

Instructions

  1. Preheat oven to 350 °F (175 °C). Grease a 9×13‑inch baking pan with butter or nonstick spray.
  2. In a large bowl, combine the chocolate cake mix and sour cream until the batter is smooth and evenly mixed.
  3. Pour the batter into the prepared pan and spread it evenly.
  4. Sprinkle the semi‑sweet chocolate chips evenly over the top of the batter.
  5. Bake for 35–40 minutes, or until a toothpick inserted into the center of the cake comes out mostly clean (a few moist crumbs are okay).
  6. Let the cake cool in the pan for 10–15 minutes before slicing.
  7. Serve warm or at room temperature — optionally with whipped cream or a scoop of ice cream.

Notes

  • You can fold chopped nuts or extra chocolate chips into the batter for added texture — just be careful not to overfill.
  • For extra indulgence, top with whipped cream, frosting, or a dusting of powdered sugar.
  • To make a gluten‑free or dairy‑free version, use a gluten‑free cake mix and substitute dairy‑free sour cream; texture may vary slightly.
  • Storing: cover leftover pieces tightly; cake stays moist for 2 days at room temperature or up to 4 days if refrigerated. Reheat slices briefly in the microwave (15–20 seconds) to restore a freshly-baked feel.
