Ingredients
3 1/2 cups all-purpose flour (spooned and leveled), plus more for work surface
1/2 teaspoon fine salt
2 sticks unsalted butter, room temperature
2 cups sugar
2 large eggs
2 teaspoons pure vanilla extract
Green, red, and yellow food coloring
Preparation
Whisk together flour and salt. In a large bowl, using a mixer, beat butter and sugar on medium-high until pale and fluffy, 4 minutes. Beat in eggs, one at a time, then vanilla. Reduce speed to low, add flour mixture, and beat until combined. Tint dough by mixing in food coloring: For trees, tint two-thirds the dough green; tint some of remaining dough red and some yellow; leave some plain. Divide green dough into 2 disks. Individually wrap all dough in plastic and refrigerate 1 hour (or up to 3 days).
