Sugar Cookies II

Preheat oven to 375°F (190°C).

Combine softened butter, powdered sugar, and granulated sugar in a large mixing bowl, then beat until light and fluffy.

Add eggs one at a time to the butter mixture, beating well after each addition.

Stir in salad oil, vanilla extract, and grated lemon peel until fully incorporated.

In a separate bowl, whisk together flour, baking soda, cream of tartar, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing until a uniform dough forms.

Shape dough into small balls and place them 2 inches apart on ungreased baking sheets.

Flatten each dough ball slightly with the bottom of a glass, then sprinkle with plain or colored sugar if desired.

Bake for 10–12 minutes until the edges are set but centers remain soft.

Remove baking sheets from oven and allow cookies to cool for 2–3 minutes on the pan before transferring to a wire rack.
