5. Divide dough into two parts, put one part back in the fridge before using. Roll out second part to about 2 millimeters and cut out round cookies with 5-6 centimeters in diameter. This can be done with a cookie cutter or glass. You should get 30 cookies in total or even more, I get about 40. Bake one baking sheet at the time for about 8-10min. Let cookies cool.

9. Chop semi-sweet chocolate and melt with butter and orange zest on low heat. Dunk each sandwich cookie into the chocolate and let cool off on parchment paper before serving.

Cooking notes

Baked goods are unforgiving with rounding — use weights rather than volumes whenever possible, and verify pan capacity if you scale up or down significantly.

For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.

When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
