Putting the cake together
Place one cake on the cake board and spread butter cream to the cake top. Add each cake with buttercream centre
On the third cake spread the buttercream over the top and sides and create a thin crumb coating. This is to fill in any gaps through the layers and refrigerate for 10-15 minutes to set.
Once set, add a layer of ganache to the full cake and use a large metal/plastic scraper to smooth over the sides for an even coat. Refrigerate for 10-15 minutes to set.
Carefully add the melted biscoff spread using a spoon to a drip fashion down the sides of the cake.HINT: I pour the biscoff onto the top of the cake and smooth it to the edges to run over the sides.
Add any additional decoration you may like to the top of the cake.
Notes
If you are making this the day before. When you tip out cakes to cool fully, wrap in glad wrap whilst still hot. This will make the cakes very moist.
