How To Make Mary Berry’s Mississippi Mud Pie
- Preheat your oven to 180°C (160°C fan) or gas mark 4. Grease a 23cm round deep, loose-bottomed cake tin.
- Crush the biscuits into fine crumbs using a rolling pin and freezer bag.
- Melt 150g of the butter in a saucepan, then stir in the biscuit crumbs until evenly coated.
- Press the mixture firmly into the base and sides of the tin. Bake for 10 minutes, then cool.
- Melt the chocolate, syrup, and remaining 50g butter together in a heatproof bowl over barely simmering water. Remove from heat and cool slightly.
- Stir in the marshmallows and pecans until they are fully coated in the chocolate mixture.
- Spoon the chocolate filling into the cooled biscuit crust, smoothing the top.
- Chill in the fridge for at least 30 minutes, until firmly set.
- Whip the double cream and icing sugar together until soft peaks form.
- Spread the whipped cream over the set chocolate filling and dust with cocoa powder.
- Refrigerate for at least one more hour or overnight for best slicing.

Common Mistakes to Avoid
- Overheating the chocolate: Always melt gently to avoid grainy texture.
- Poor crust compression: Firmly press the biscuit base for stability.
- Skipping the chill times: Proper chilling ensures clean, neat slices.
- Overwhipping the cream: Aim for soft peaks, not stiff or curdled texture.
- Using fresh marshmallows: Slightly stale marshmallows hold their shape better.
Storage and Reheating Instructions
- Storage: Keep covered in the fridge for up to 4 days.
- Freezing: Wrap tightly and freeze for up to 2 months. Thaw in the fridge before serving.
- Reheating: Not typically recommended, but individual slices can be microwaved gently for 10–15 seconds if you prefer a softer texture.
