For the topping

  • 300ml double cream


  1. Heat oven to 180C/160C fan/gas 4. In a food processor, whizz the biscuits to a fine crumb. Pour in the melted butter and pulse briefly to mix well. Spoon into a 24cm pie dish and press into the base and up the sides. Bake in the oven for 10 mins to firm up.

  2. To make the brownie layer, melt the butter and chocolate together in a bowl set over a pan of simmering water (making sure that the bottom doesn’t touch the water), or in short bursts in the microwave.

  3. In a separate bowl, whisk the eggs until pale, fluffy and doubled in size, then add the sugar and whisk until thickened. Fold in the chocolate mixture, then sieve in the flour and fold in.

  4. Pour into the baked biscuit case and return to the oven for 15–20 mins until the brownie has a crust on top. Set aside and leave to cool (if the brownie has risen a lot, it should sink down slightly as it cools).

  5. Once the brownie base is cooled, put the custard, chocolate and vanilla in a pan and cook over a medium heat, stirring, until the chocolate has melted into the custard. Remove from the heat.

  6. Soak the gelatine in a little cold water and, once softened, remove from the water and squeeze to remove any excess. Stir into the warm custard mixture until dissolved. Let the custard cool slightly, then pour over the brownie layer. Put in the fridge for a few hrs, or overnight, until set.

  7. Remove the mud pie from the fridge about 30 mins before serving so that it can come to room temperature for easy slicing. Just before serving, whip the cream to soft peaks and spoon it over the custard layer, then grate over some dark chocolate.

Loved this! Only used 2 sheets of gelatine after reading the comments and the custard set beautifully.

Seemed a shame to waste the Oreo centres so I crumbled them over the top. Didn't have a pie dish so just used a spring loose bottomed tin and layered the base/fillings, worked well. Looks impressive

Seriously rich & chocolatey! Only problem was the dish was full when I had added the brownie so I had to serve the chocolate custard separately, will need a bigger dish or else less brownie.

Yum! The gelatine made the custard layer super firm so it cut really nicely but I think I'll only use 2 sheets next time. Rich but surprisingly not excessively sweet.

This was a hit with my adult children who like oreos and brownies.
I actually made my own vanilla custard and added the chocolate and did not need any gelatine. I used 2 egg yolks, 2 tsp cornflour, 25g caster sugar, .5 tsp vanilla essence, 200 ml milk and 200 ml double cream. Mix egg yolks, cornflour, caster sugar and essence then add milk and double cream. Add 50g chocolate and keep stirring. It will be ready in about 6-8 minutes. You can then leave it to cool and add to brownie. (Replaces steps 5+6)
