Best Sugar Cookies Ever!

I have tried for years to find that fool proof sugar cookie recipe and have failed time and time again. Each one is either too sticky, too chewy, to crunchy, too sweet, has too many ingredients, or just doesn't bake up well. I was at my daughter's preschool class, and the student teacher brought in these wonderful sugar cookies for them to decorate. At first, I thought it was "cheater dough" from the store, but it was from scratch! So, of course I had to have it. These are the best sugar cookies I have ever had, or made! They are smooth, tender, flaky, and have just the right amount of sweet to go with your favorite frosting. Okay, enough about them, here's the recipe!

SUGAR COOKIES
(Thank you Mr. Noles!)

1 C. Sugar
2 eggs
1/2 Tsp. Salt
1/2 Tsp. Baking Soda
1 C Butter, softened (don't melt!)
4 Tbsp. Milk
1 Tsp. Vanilla
4 C. Flour

Mix sugar, eggs, salt, soda, butter, milk, and vanilla with a mixer on low speed. Stir in the flour one cup at a time. Knead the dough to make a smooth consistency. Roll out on a floured surface about 1/4 inch. Cut to desired shapes. Bake at 375 for 9 minutes. Thinner cookies will cook more quickly.
