This is the simplest recipe and it's delicious! It looks a bit like a car crash though, so I always pop it in a heart-shaped tray to make sure that it looks a bit prettier. I actually used a silicone tray for this that I picked up at Ikea a few months ago, I can't find it on their website but it looks like this and there are tons of them on eBay.
As always, I followed my basic cake recipe and folded in 100g of ground almonds and a tbsp of almond extract. Once the cake mix was in the tray, I added around 5 big tbsp of homemade strawberry jam and swirled it around a little bit. It's a pretty big cake, so bake it for around 40 minutes on gas mark 4. Enjoy!
