This may be our family's number one favorite cookie. This soft, cake-like cookie tastes like Panera Bread's orange scones if you've had them. The orange icing is the best! The recipe make a lot of cookies, so cut the recipe in half if you'd like.
adapted from an old family recipe
5 cups all-purpose flour
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
2 cups sugar
1 cup butter, at room temperature
2 tablespoons orange zest
1 cup buttermilk
1/2 cup orange juice
Preheat oven to 375 degrees F. Combine flour, baking powder, baking soda, and salt in a medium bowl and stir with a whisk to combine. Combine buttermilk and orange juice in a 2-cup measuring cup. Cream the butter and sugar, and zest in the bowl of an electric mixer until light and fluffy, about 3 minutes. Add eggs, one at a time, mixing well after each addition. Scrape the bowl as needed. Alternate adding the flour and buttermilk mixtures starting and ending with the flour mixture. Drop by tablespoons or by a cookie scoop onto a cookie sheet lined with a Silpat mat or parchment paper. Bake for 10 minutes or until the bottoms are just beginning to brown. Cool completely before topping with orange icing (recipe follows).
3 tablespoons butter
3 3/4 cups confectioners' sugar (1 pound box)
4 to 5 tablespoons orange juice (approximately)
1 1/2 teaspoon finely grated orange peel
a pinch of salt
Cream butter, orange zest and salt in a bowl with an electric stand or hand mixer. Add sugar gradually, alternating with enough orange juice to make frosting the right consistency for spreading.
