Mars Bar Mud Cake

Mars Bar Mud Cake

Serves 16

400g butter, chopped
400g good-quality dark chocolate, chopped
1/2 cup cocoa powder
2 cups caster sugar
6 eggs, lightly beaten
1 1/2 cups self-raising flour
2 x 60g Mars Bars, chilled, chopped
double thick cream, to serve (optional)

1. Preheat oven to 160°C. Grease a 4cm-deep, 22.5cm x 28cm (base) slab pan. Line with baking paper, allowing 2cm overhang at both long ends.
2. Combine butter and dark chocolate in a large, heatproof, microwave-safe bowl. Microwave, uncovered, on MEDIUM-HIGH (70%) for 3 to 4 minutes, stirring every minute with a metal spoon, or until almost melted. Add cocoa and whisk until smooth.
3. Add sugar and mix well. Add one third of the egg and stir to combine. Repeat with egg in 2 batches. Sift flour over chocolate mixture. Stir gently until just combined. Pour mixture into prepared pan. Sprinkle Mars Bars over batter and press in slightly.
4. Bake for 60 to 65 minutes or until a skewer inserted into the centre has moist crumbs clinging. Cool completely in pan. Cut into squares. Serve with cream.

  1. I made this for my mate for her Birthday. It is full of sugary goodness and totally fattening. I topped with combined Chocolate (400g) and Butter (approx 60g) – Melted .. and sprinkled with coloured chocolate chip rock things. It was moist and rich ! Keep stored in fridge.
