The Yule Log recipe I use is James Martin's and it is really good. It's a bit tricky to assemble but don't worry too much if it breaks up as you can cover it all in the chocolate coating. Also when making the chocolate coating make sure the melted chocolate has cooled well enough before adding the cream, as otherwise it will all drip off. I also think it tastes better two days later.
The recipe is:
175g dark chocolate
6 medium eggs
175g caster sugar
Filling:
85g dark chocolate
200ml double cream
Topping:
200ml double cream
100g dark chocolate
Melt the chocolate. Then separate the eggs. Add the caster sugar to the egg yolk and beat until light and fluffy. Whisk the egg whites until stiff but not dry. Then once the chocolate has cooled add this to the yolk and sugar combo and put over a heat until blended. Then fold in the egg whites. Pour into a swiss roll tin, which has been lined with greaseproof paper, and cooked on gas mark 4 for 20 minutes until light to touch. Once cooked put a dry towel on the tin and then a cold wet towel on top. Leave to cool.
Then tip it onto greaseproof paper and take off the other paper. Spread the melted chocolate for the filling onto this. Then the whipped double cream. Roll it up using the paper.
Then melt the topping chocolate and when it has cooled add the cream. Stir and then spread on top. A moreish chocolate dessert.

I do find them tricky to make. Firstly finding chestnuts but this year there seemed to be an abundance of tinned chestnuts so it wasn't so bad. I used puree chestnuts. Then the rest is quite self explanatory. Although I would say make the biscuits quite thick.
The mince pie recipe I use is from an old cook book.
The ingredients are 200g self raising flour and 100g butter and cooled water. Rub the butter into the flour until like breadcrumbs. Then gradually add cold water and mix with a round end knife until it is like a dough. I think it is better to chill it but the other day I rolled it out straight away. This makes 12 mince pies. I always use Robinson's mince meat from a jar.
I also made these chocolate cupcakes, as a gift. I didn't try the cake but the icing was amazing! Very rich :)
