Soft, buttery vanilla cookies filled with creamy buttercream and festive sprinkles, just like the classic Christmas Tree Cakes!
Ensure all dairy ingredients are at room temperature for the best cookie dough and buttercream texture.
Chill the cookie dough for the full duration to prevent spreading and maintain sharp cut-out shapes.
Do not overbake the cookies; they should be soft, not crispy.
Allow cookies to cool completely before frosting to prevent the buttercream from melting.
