01 - Preheat oven to 350°F. Grease a 9x13 inch baking pan thoroughly.
02 - In a large bowl, combine red velvet cake mix, eggs, vegetable oil, buttermilk, and vanilla extract. Beat until completely smooth and well incorporated.
03 - Pour the cake batter evenly into the prepared baking pan, spreading to corners.
04 - In a separate bowl, beat softened cream cheese and butter until creamy and smooth. Add powdered sugar and vanilla, continuing to beat until fluffy and no lumps remain.
05 - Drop spoonfuls of the cream cheese mixture randomly over the surface of the cake batter.
06 - Using a knife or skewer, gently swirl the cream cheese mixture through the batter in a figure-eight pattern. Do not overmix—distinct marbling creates the earthquake effect.
07 - Sprinkle chocolate chips, chopped pecans, and shredded coconut evenly across the entire surface.
08 - Bake for 38–42 minutes until edges are set but center remains slightly gooey. The cake should not be completely firm in the middle—this texture is intentional.
09 - Let cake cool in the pan for at least 30 minutes before slicing. Serve warm for maximum gooeyness or refrigerate for a firmer, fudge-like consistency.
