Ingredients

• 1/2 cup butter, softened
• 1 cup granulated sugar
• 1 large egg
• 1 egg white
• 1 1/2 tablespoons sour cream
• 1 teaspoon vanilla extract
• 2 1/2 cups all-purpose flour
• 1/2 teaspoon baking powder
• 1/2 teaspoon salt
• 1/4 cup unsalted butter, softened
• 2 cups powdered sugar
• 2-3 tablespoons half and half
• 1/2 teaspoon vanilla
• food coloring (optional), according to taste

Method

1. Grease a 9 x 13-inch pan and heat the oven to 375°F for the cookie base.
2. Stir the flour, baking powder and salt together in a large mixing bowl and set that dry mixture aside.
3. Cream 1/2 cup butter with the granulated sugar for about 3 minutes, until the mixture looks fluffy.
4. Beat the egg, egg white, sour cream and 1 teaspoon vanilla extract into the creamed butter, then fold in the flour mixture until a soft dough forms.
5. Press the sugar cookie dough evenly across the bottom of the greased pan with gentle fingertips.
6. Bake the slab for 17 to 20 minutes, until its edges tint lightly golden and a toothpick pushed into the centre emerges clean.
7. Cool the baked bars completely in the pan before any frosting touches them.
8. Whip 1/4 cup unsalted butter with the powdered sugar and half and half until the frosting turns fluffy, then beat in 1/2 teaspoon vanilla and food coloring if a tint is wanted.
9. Spread the vanilla frosting over the cooled sugar cookie bars and cut the slab into portions.
