These cookies are soft with a chewy center. They might be the easiest sugar cookies ever. They will NOT make good cookies for icing. They are too soft in the center.
Do not melt the butter for this. Instead, let it set on the counter until very soft. I set mine out for 1-2 hours before baking. Melted butter will make flat cookies. The soft chewy center forms when the butter is the perfect temperature.
1/2 cup butter, very soft
1/2 teaspoon baking soda
1/2 teaspoon cream of tartar
1/4 cup cream cheese
3/4 cup sugar
1/2 teaspoon salt
1 teaspoon vanilla
1 egg
2 cups flour
Preheat the oven to 375 degrees. Cream the butter, cream cheese, and sugar. Add the vanilla and egg. Mix thoroughly. Add the baking powder, baking soda, and salt. Slowly add the flour and mix fully. Roll into tablespoon size balls. Bake on silicone mat for 8-10 minutes. Do not let them brown.
