Baking With Spirit: The April Challenge

Since this month contains Easter, I thought I'd go with a chocolate theme for the Baking With Spirit challenge. Creme de Cacao is surprisingly difficult to find in the supermarket, though, so as a compromise I've decided to ask you all to bake something that contains both chocolate and alcohol.
There is a vast range of choice here, so I'm hoping to see some interesting posts!
Don't forget to check out last month's dark spirits round up for ideas on what to bake with whisky (apparently Baking With Spirit entrants' favorite dark spirit).
Finally, before I give you the rules, I'm running out of ideas for the challenge, so if anyone is interested in hosting a particular month please let me know!
Here are the rules (find a comprehensive list here):

1. Make something food-related containing chocolate and alcohol.
2. Write a post about it on your blog, link back to Cake Of The Week and mention Baking With Spirit.
3. Email the link to me at cakeoftheweek@hotmail.co.uk and include your name, your blog and the photo you want me to use in the round-up. If you tweet me @CakeOfTheWeek and/or use #bakingwithspirit I will endeavour to retweet!
4. The deadline is midnight on the 28th.

Don't forget that The Food Blog Diary is a handy site where a lot of the UK blogging challenges are collated into a list. It makes it a whole lot easier to remember what to enter when!
