Prep the dough
1- Roll into a ball, wrap with plastic wrap, and refrigerate for 2 hours.
2- Remove the dough from the fridge and cut into two pieces.
3- Roll each piece on a floured surface until about 1/4" thick.
4- Cut with your favorite cookies cutters.
Bake the cookies
1- Preheat oven to 375F.
2- Bake on the middle rack about 9-10 minutes, until the edges are golden brown.
3- Let cool on the pan for 2 minutes, then transfer to a cooling rack.
Decorate the cookies
These cookies are delicious eaten plain but are more festive when decorated. Add sprinkles before baking. Or coat them with royal icing after they're completely cooled.
