Step 1

Soften the butter and mix it with the grated parmesan cheese in one bowl. Mix the flour, baking powder, chili, and garlic powders together in a separate bowl.

Step 2

Add the flour mixture to the butter mixture and work it into a dough, adding small amounts of egg to help it come together. Do not add all the egg at once, and stop before it gets wet and sticky. A little bit sticky is fine.

Step 3

Turn the dough onto a piece of plastic food wrap and use that to form it into a long sausage (around 9 inches). Wrap it in the plastic cling film and roll it to even out the sides. Chill in the freezer for 15 minutes whilst the oven preheats.

Step 4

Preheat the oven to 175 C / 350 F

Step 5

Take the dough out of the freezer and brush it with an egg wash before rolling it in the seed mix to form a crust.

Step 6

Slice the parmesan cookie dough into thin disks 0.5cm thick and place them on a lined baking tray.

Step 7

Bake the spicy parmesan cookies in the oven for 10-15 minutes until they have risen slighty and are golden brown in color.

Step 8

Remove them from the oven and leave them to harden up for 10 minutes before serving them still warm.
