Should you be having a mouse-themed children’s party – and why not? – then these little fellows could be just the answer. We’ve used cookie cutters shaped like a mouse head but you can use any shape you like for these delicious cheesy biscuits for any other type of occasion. They’re sure to be snapped up fast.
- 4½ ounces / 125g plain flour + extra for dusting
- 4¾ ounces / 135g Parmesan  cheese, finely grated 
- ¼ teaspoon of cayenne
- 3½ ounces / 100g unsalted butter, cubed
- 1 large egg yolk
Put all of the ingredients (except the egg and 2 tbsp of the parmesan) into a food processor with a good dash of seasoning and blitz until everything is starting to come together.
Add the egg yolk and continue to blitz until the mixture comes together to form a smooth dough.
Roll the dough into a ball, flatten into a disc and transfer to the fridge to chill for 30 minutes.
Line two baking trays with greaseproof paper and preheat the oven to 180°C / 356°F (160°C / 320°F fan).
Lightly flour a surface with flour and roll out the dough until it’s about ½ cm or ⅕th inch thick. Using a mouse shaped cookie cutter, cut out your biscuits and place them evenly on the baking trays, a couple of centimetres apart.
Sprinkle the remaining parmesan over the top of the biscuits and cook in the oven for 12-15 minutes or until turning golden.
Cool and serve.
