In a large mixing bowl, add the peanut butter, icing sugar, egg and salt. Then whisk well until all ingredients are combined and a paste is formed.
Add half of the plain flour to the mixture, then fold in to combine. Then add the other half and repeat the process until the flour is fully incorporated.
Make small peanut butter cookie balls and place on a baking tray with baking paper.
Garnish the cookies by gently pressing half of a roasted peanut in the middle.
Finally, brush the cookies with milk or beaten egg yolk for a nice finish.
Preheat your oven to 160C (Fan Forced), then bake for 18 to 20 minutes or until golden.
Allow the cookies to cool down on the tray for about 5 - 10 minutes then Enjoy!
