Bloody Valentine Cake

Sometimes, when the st. Valentine’s Day is close and I see all those hearts, chocolate pralines and pink things around I feel like making a little fun of it. And sometimes I see it through and do something “different”. Last year’s also very bloody Valentine cake was a great success in that department and this year’s cake isn’t going to be any different!

The cake has a tiny immitation of the human heart with pieces of broken glass around it. Everything is soaked in blood, of course. The base of the cake is a plain biscuit with vanilla buttercream, the heart is chocolate and the glass is made from sugar and syrup. And when you cut the cake, your guests will be awed (or disgusted) but a bloody surprise inside:

How to make the Bloody Valentine Cake

If you have the time and space, make the modelling chocolate and candy glass a day before. And if you want, also the biscuit. The tutorials to all the parts of this cake are on my blog and I link to them in this tutorial.

Candy Glass

Modelling Chocolate

Make the modelling chocolate with this tutorial using the ingredients above. Let the chocolate cool down, wrap it and let it rest at least for one hour.

Bake the Biscuit

Separate the egg whites from the yolks. Beat the whites until you have a solid snow. Whisk the yolks with sugar, then add oil and little by little the baking powder and flour. In the end add vanilla extract and yoghurt and slowly incorporate the snow.

Grease the cake molds, divide the batter into them equally and bake for 25 minutes in an oven preheated to 160 °C/320 °F.

When the biscuit is baked golden, take it out of the oven, let it cool down and take out of the mold.

The tiny heart on the top of the bloody valentine cake is made from biscuit crumbs and buttercream and it’s covered with modelling chocolate. If you want to see in detail how I make the hearts and its parts, read my Human Heart Cake tutorial. I am going to describe it only roughly here.

Pour some blood over the glass (it won’t really stick) and then pour a generous amount on the cake. Let the blood run down the sides of the cake.
