- 125g butter, at room temperature
- 1/2 cup finely grated cheddar cheese
- 1/2 cup finely grated parmesan cheese
- 2 eggs
- 1 1/4 cups plain flour, sifted
- Flour, for kneading
- Sesame seeds, to decorate
Preheat oven to 180°C (160°C fan-forced). Line 2 large baking trays with baking paper.
In a large bowl, mix butter and cheeses with an electric mixer until well combined. Add 1 egg and mix well.
Add flour, and season with salt and pepper. Fold with a large metal spoon, until dough just comes together.
Turn out dough onto a lightly floured surface. Knead until smooth. Shape into a 2cm thick log. Wrap in plastic wrap and refrigerate for 1 hour, until firm.
Remove dough from plastic wrap and roll out between two sheets of baking paper until it is 4mm thick. Cut out biscuits using a 5cm cookie cutter. Place on prepared trays. Re-roll off-cuts to cut out more biscuits and not waste any mixture.
Lightly beat remaining egg. Brush each biscuit with egg, then scatter over the sesame seeds.
Bake for 12-15 minutes, until golden. Leave to cool on trays for 5 minutes, then transfer to a wire rack to cool completely.
