Adam made this in his first cooking class in co-op in the fall of 2007. His note on the page says "Adams favorites have a √". And this recipe has a check mark. Not a square root but apparently there is not a check mark to be had on the ALT list.
1½ cup flour
½ cup butter, melted
6 tbsp powdered sugar
½ tsp vanilla
6 tsp cold water
large container of yogurt, any flavor
Preheat oven to 375°. In a bowl add flour and powdered sugar. Mix together. Add butter and stir until mixture is crumbly. Slowly stir in cold water and mix thoroughly. Grease muffin tins and spread dough in each of the muffin cups. Press dough up along sides of each cup. Bake until golden brown about 10 minutes. Allow to cool, fill with yogurt and serve. Makes 6
