Beat ¾ cup unsalted butter with ¾ cup light brown sugar until smooth and creamy, about 1 minute.
Add 1 egg and beat until incorporated.
Add 1 teaspoon vanilla extract and ¼ teaspoon almond extract and mix well.
Sift dry ingredients: 2 cups all-purpose flour, ½ teaspoon baking powder and ¼ teaspoon salt (I measure them and sift directly over the butter mixture). Add them in 2 or 3 parts to the butter, mixing at low speed and only until combined and no dry spots remain.
Divide the dough into two or three parts. Cover well in plastic wrap and chill for at least half an hour and up to 2 days.
When ready to bake, place each portion of dough between sheets of parchment paper, roll about ¼ inch thickness (add some flour if needed to prevent the rolling pin from sticking) and place on cookie sheets.
Refrigerate them for another 15-20 minutes, or freeze for five minutes, or until they are very cold but not starting to crack.
Preheat the oven to 350ºF (180ºC).
With cookie cutters cut dough into the shapes you want. I used the star cookie cutters from Sur La Table.
Place the cut cookies on baking sheets and bake for about 10 minutes, until dry and just starting to color. If you want chewy centers underbake them for a minute or two. Careful as different sized cookies will have different baking times.
Let cool completely on a wire rack before glazing.
For the glaze:
Mix ½ cup confectioners’ sugar with 1 teaspoon lemon juice. Add more in drops until you have a thick and smooth consistency, similar to thick honey.
To assemble:
Take the largest star cookie and glaze the top. Place on the serving plate and sprinkle the ends with colored sugar and crushed peppermint candy.
Continue glazing and piling the other star cookies, from the largest to the smallest. Be sure to alternate pointed ends so you create a tree.
Let the glaze set before you move the tree.
Repeat if you made cookies for more than one tree.
Notes
Bake ahead: the cookies can be baked ahead and kept in airtight containers or tins for about a week. The dough can be frozen for up to a month.
