Easy Slow Cooker Lava Cake

This is a chocolate lovers dream dessert. Rich warm moist chocolate cake rises to the top of the slow cooker as it cooks, with a layer of thick hot chocolate fudge sauce on the bottom. It is an easy and delicious dessert. I love to take a recipe with a lot of ingredients and figure out a way to make them with less ingredients, but still have the same flavor. The original recipe that I had for a Lava Cake had 12 ingredients; my version of it has only five.

Step-by-step

  • In large bowl, combine cake mix, 3/4 cup water, and 1/4 cup vegetable oil. Mix well. Spread in the bottom of a 4-quart slow cooker sprayed with cooking spray.
  • In medium bowl, combine sugar, cocoa powder, and 1 1/2 cups VERY HOT water. Mix well.
  • Pour mixture into slow cooker. Cover with lid. Cook on high 2 to 2 1/2 hours. I cooked mine for 2 hours.
  • Turn off slow cooker. Let cool 15 to 30 minutes to thicken up the sauce.
  • Serve warm with vanilla ice cream if desired.
Dark chocolate batter rests above a pooling liquid fudge layer that thickens during a mandatory resting window. Porous cake mixes absorb moisture rapidly when subjected to direct ambient heat, making precise timing critical.

Managing Thermal Mass

A four-quart ceramic insert retains heat unevenly compared to metal vessels. Pour the boiling water and cocoa mixture gently over the batter rather than stirring them together. Density differences create the dual-texture phenomenon as the starch sets near the upper heating zone. Condensation dripping from the lid dilutes the surface if the cooker is opened prematurely. Keep the lid secured for the full two hours to maintain internal steam pressure.

Resting and Structural Integrity

Liquid sauce requires cooling time to reach the proper viscosity. Shut off the power source entirely at the two-hour mark. Let the ceramic crock sit uncovered for twenty minutes so starches retrograde sufficiently. Scooping too early results in a thin puddle rather than a clinging sauce.
