Ingredients
Method
- Heat oven to 350°F and arrange rack in the middle. In a large bowl, whisk together flour, baking soda and salt.
- Combine butter and sugar in the bowl in the bowl of a mixer fitted with the paddle attachment. Beat on medium speed until light and fluffy and sugar is dissolved, about 4 minutes. Add eggs and continue beating on medium until combined.
- Add sour cream, orange zest, juice, and marmalade and beat until combined. Stop mixer and scrape down sides and paddle with a rubber spatula. Add flour mixture and beat on low until incorporated.
- Drop by tablespoons onto an ungreased cookie sheet and bake for 10 to 12 minutes or until the bottoms are just beginning to brown. Let cool for a couple of minutes, then remove to a rack to cool completely.
For the Frosting:
- Combine butter, orange juice and zest in the bowl of a mixer fitted with the paddle attachment and beat until combined. Add 2 cups of the powdered sugar and beat until incorporated. Add more, a 1/2 cup at a time if needed—frosting should be thick, but still spreadable.
- Once cookies are cool, frost and serve immediately or can be frozen for up to 1 month.
