I used this recipe for Butter Biscuits, the recipe was OK. I'm sure that there are better ones out there, l would probably also use a chocolate biscuit recipe just to capture the brightness of the colours.
For the filling l just used a buttercream icing, which is approximately 90g of butter softened, 1 cup of icing sugar, 1 tsp of Vanilla Extract. Mix all ingredients together until light and fluffy, divide mixture into small bowls, colour accordingly and place a large dollop of icing mixture in the centre and then sandwich together with another biscuit.
I would love to hear you comments and suggestions, so please feel free to leave a comment.
Enjoy! Y x
