Step 1
Preheat the oven and prepare a baking tray with baking paper. In a mixing bowl, combine butter and sugar until smooth and creamy. Add egg and vanilla, then mix again until fully combined.
Step 2
Add flour gradually into the bowl and mix until a soft dough forms. Avoid overmixing the dough to maintain a tender biscuit texture. Cover the dough and let it rest briefly before rolling.
Step 3
Roll the dough evenly and cut round biscuit shapes using a cutter. Place the biscuits on the prepared tray with enough spacing between them for even baking.
Step 4
Bake the biscuits until lightly golden.
Step 5
Allow them to cool completely before assembling.
Step 6
Spread jam onto one biscuit and sandwich with another.
Step 7
Mix sugar and milk to create a smooth icing. Spread icing over the top biscuits evenly and allow it to set before serving. Serve with tea or coffee for a classic homemade snack.
