Description

Mars Bar Cake by jamie oliver combines chocolate, caramel, and crisp rice for an indulgent British dessert. Chocolatey layers and sweet textures make this treat irresistible for you to enjoy at home.


Ingredients

Scale
  • 4 Mars Bars, chopped (51 g/1.8 oz each; if using multipack bars of 39.4 g/1.4 oz, use 6 bars)
  • 225 g/8 oz Rice Krispies or similar crispy rice cereal
  • 75 g/2.6 oz butter
  • 3 tbsps golden syrup
  • 200 g/7 oz milk chocolate (use 300 g/10.5 oz for a thicker topping)
  • 1 Mars Bar for decoration (optional)

Instructions

  1. Preparation: Grease a 9×9-inch baking pan and line with parchment paper, ensuring full coverage of bottom and sides.
  2. Chocolate Base: Melt Mars Bars, butter, and golden syrup in a heavy-bottomed saucepan over low heat, stirring continuously until achieving a smooth, glossy texture. Remove from heat and fold in Rice Krispies, coating every piece thoroughly with the rich chocolate mixture.
  3. Setting Foundation: Transfer the chocolate-coated cereal into the prepared pan, pressing and distributing evenly to create a compact, level surface. Allow to set at room temperature for 15-20 minutes or refrigerate for faster cooling.
  4. Chocolate Topping: Carefully melt milk chocolate using a double boiler or microwave in short intervals, stirring to prevent burning. Pour evenly over the cooled cereal base, tilting pan to ensure complete coverage. Optionally, sprinkle chopped Mars Bar pieces for added texture and visual appeal.
  5. Finalizing: Refrigerate for 1-2 hours until chocolate layer is completely set and firm. Slice into square or rectangular pieces using a sharp knife before serving.

Notes

  • Butter Matters: Use unsalted butter for better control of sweetness and a cleaner chocolate flavor profile.
  • Gentle Heating: Melt Mars Bars and butter on extremely low heat to prevent scorching and maintain smooth chocolate consistency.
  • Coating Technique: Stir Rice Krispies thoroughly to ensure every single piece gets completely enveloped in chocolate mixture for uniform taste and texture.
  • Cooling Crucial: Allow proper setting time at room temperature or refrigerator to achieve perfect firm yet slightly chewy texture that holds together seamlessly.
