INSTRUCTIONS In a large bowl cream the butter and sugar until creamy, add vanilla and mix until incorporated. Add flour and walnuts and mix with a rubber spatula until well combined. Shape dough into balls. Place on top of the cooking tray that comes with your Omni Pro leaving enough space between them, bake in batches if needed. Select Bake, set the temperature to 315°F / 157°C and set time to 20 Minutes. Press Start. Once the Omni is preheated, insert the cooking pan on the Roast/Bake Level into the Omni. Bake until the bottom of the cookies is slightly brown. Once the cooking cycle is finished, remove the cooking tray and let the cookies cool down for about 5 Minutes. While the cookies are warm to touch, sift the icing sugar over. Enjoy!
