Add the flour, corn starch, baking powder and salt to a large mixing bowl and use a whisk to combine. Set aside.
Add the butter, cream cheese and sugar to a separate bowl and use an electric mixer to beat until well combined and pale, about 3minutes. Beat in the egg, vanilla extract and almond mixture until well combined.
Add half the dry ingredients to the butter mixture and use a spatula to mix until a dough forms. Add the remaining dry ingredients and repeat.
Transfer the dough to a large piece of plastic wrap. Wrap up, and chill for 1 hour.
Preheat your oven to 175°C / 350°F. Line two baking trays with baking paper, set aside.
Unwrap the dough and dust your workbench with a little flour. Use a rolling pin to roll out to about 1.2cm / 1/2-inch thick. Use a7.5cm / 3-inch round cookie cutter to cut out as many cookies as you can. Roll the dough back up and cut as many cookies as you can, about 16.
Place on the baking tray and bake for 12 minutes. Allow to cool.
