Chocolate Halloween Cake with Spiced Bat Biscuits

Sometimes cake ideas come to me fully formed, sometimes they come from needing to use up leftovers, and sometimes I get a fun new toy I can’t wait to play with. A few weekends ago on a trip to TK Maxx to buy some pretty pots for some of my plant jungle (is 27 plants in the living room too many? If it is I don’t care!), I spied some Halloween cookie cutters. My cookie cutter collection didn’t have anything spooky in it at all, so I decided to buy them as a little treat.Chocolate Halloween Cake with Spiced Bat Biscuits

Once I had them home I couldn’t stop thinking about the bats, and how they would look great flying over a really dark coloured cake, maybe with a little yellow fondant moon. Even though I’d decided not to make another Halloween cake this year to focus on the Great British Bake Off Technical challenges I’m baking along with, those little bats kept popping into my mind, and I decided to go for it anyway.Chocolate Halloween Cake with Spiced Bat Biscuits

In keeping with Halloween, the biscuits are heavily spiced and flavoured with orange. Before the went in the oven, I stuck cocktail sticks halfway in, to make them easier to attach to the cake later. The royal icing is my now go-to recipe, made with aquafaba. There are lots of benefits of using aquafaba over eggs whites: it means anyone can eat them without fear of consuming raw egg; and it uses up something that would normally be thrown away. There is no chickpea smell or taste, I guarantee it. The icing itself I did by lining and then flooding each cookie. After they were dry, I added on details the next day and let dry again thoroughly.Chocolate Halloween Cake with Spiced Bat Biscuits

After crumb coating the cake and leaving to cool in the fridge, I mixed several really dark coloured bowls of buttercream in navy, red and purple. I added it randomly to the outside and spread round for an uneven watercolour effect. There was no fondant in the cupboard, so I had to go without the moon, which I’m a bit sad about . The Boyf also suggested that the bat on the side distracts from the ones on the top – what do you think? Chocolate Halloween Cake with Spiced Bat Biscuits

I made some other cookies too, to practice my piping and decorating. The little mummies are really simple but I love the effect. Spice Halloween Biscuits

  4. Add the treacle and orange flavour, mix to combine.
  5. Add the flour mix in two parts and mix on low until it comes together. Put a tea towl over the whole mixer to stop it going everywhere.

1/2 tsp orange flavouring, or which ever you like



  1. Whisk the aquafaba for a minute until frothy. Beat in the icing sugar and flavour until combined. Then beat on medium for 5-7 minutes, then on low for a few minutes (to get rid of any big air bubbles)
