Two chocolate biscuit layers sandwiched together by a creamy chocolate buttercream.
Both crunchy and smooth in texture makes this sandwich-style biscuit a perfect treat to drunk in your tea or cup of cocoa.
This bake was inspired by a recipe from the ‘Creative Chocolate Cookbook’ published by Cadbury in 1984. I love this cookbook for many reasons – not only the delicious recipes, but the memories I have of looking through it as a young child at my grandma’s house and being fascinated every time.
Ingredients
Biscuits:
- 125g DF Butter
- 125g Caster Sugar
- 1 Egg
- 1 Tsp Vanilla Extract
- 300g GF Plain Flour
- 25g Cocoa
Buttercream:
- 50g Cocoa
- 200g Icing Sugar
- 1-2 Tbsp DF Milk (I use Oat Milk)
Instructions
Biscuits:
Preheat the oven to 160 °C.
Put the butter and sugar in a mixing bowl and cream together.
Once combined, gradually add in the beaten egg and vanilla extract.
Sieve in the flour and cocoa and mix together. Mix until a dough is formed.
Place the biscuit dough between two sheets of non-stick baking paper and roll out to around 3-4mm thick.
For these biscuits, I used by embossed ‘Queen of the Desserts’ rolling pin. However, a regular rolling pin works fine, but the biscuits will be plain in pattern. Therefore, you can add your own design once you cut out your biscuits.
Use a rectangle biscuit cutter to cut out your biscuits.
Place the biscuits on a greased or non-stick baking tray and pop them in the oven.
Bake for about 15-20 minutes.
Leave the biscuits to cool before icing.
Buttercream / Decorating:
In a large bowl, mix together the cocoa, icing sugar and milk until a smooth buttercream is formed.
Spread one of the plain biscuits with a thick layer of the buttercream and sandwich together with another plain biscuit.
Wipe off any excess buttercream.
Repeat the process to make the rest of the Bourbon Biscuits.

I also made one giant Bourbon Biscuit and left a few plain too.
I look forward to seeing your creations!
