Cookies:
1/2 cup salted butter, softened
1 cup white sugar
1 egg
1 and 1/2 Tbsp. sour cream
1 tsp. vanilla extract
2 and 1/2 cups bread flour (or all-purpose flour is fine)
1/2 tsp. baking powder
1/2 tsp. salt
Orange and yellow food coloring

Frosting:
4 cups confectioner's sugar
1/2 cup salted butter, softened
1/4 cup half & half
1 tsp. vanilla extract {I used clear vanilla, so the frosting would be more white, but any kind works}
A pinch of salt
