Ingredients

• 175g Softened Butter
• 50g Golden Caster Sugar
• 50g Icing Sugar
• 2 Egg Yolks
• 2 Tsb Greens Vanilla Powder (or 2 Tsp Vanilla Extract)

• 100g softened butter
• 140g icing sugar, sifted, plus a little extra
• 2tbsp Greens Custard Powder
• Few Drops of Greens Yellow Food Colouring

Directions

• Heat oven to 200C/180C fan/gas 6.
• Mix the butter, sugars, egg yolks and vanilla with a wooden spoon until creamy, then mix in the flour in 2 batches.
• Roll out thinly on a floured surface, then use a standard 30cm ruler as a template to cut the dough into small, even squares.
• Do this by starting with the ruler flush with one side and cutting along the length of it.
• Repeat across the width of the dough, then do the same from the top down.
• Transfer to baking sheets and bake for 8-10 mins until golden.
• While the biscuits cool, mix the butter, icing sugar, custard powder and food colouring, if you have any.
• Pipe or spread a little icing onto a biscuit, then sandwich with 1 or 2 more biscuits.
• Repeat until all the biscuits are used, then dust with a little more icing sugar.
