Before You Begin
Preheat and prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients. Blot pumpkin purée thoroughly and chill dough as directed to ensure clean slicing and defined spirals.
Prepare Pumpkin
Spread pumpkin purée on paper towels or a clean cloth and blot until thick and paste-like with no visible liquid.
Make Dough
Cream butter and sugar until smooth. Mix in pumpkin purée and vanilla. In a separate bowl whisk flour, spices, baking powder, and salt, then add to the butter mixture and mix gently until just combined.
Roll Dough
Divide dough in half. Roll each portion into a rectangle about ¼ inch thick. Dough should appear smooth and even.
Add Filling
Brush melted butter over dough and sprinkle sugar-spice mixture evenly.
Roll & Chill
Roll tightly into logs. Wrap and refrigerate at least 2 hours or up to 3 days.
Slice & Bake
Preheat oven to 350°F (177°C). Slice logs slightly under ½ inch thick. Place cookies 2 inches apart.
Bake 13–15 minutes, or until edges appear lightly golden and centers look set but still soft.
Cool
Let cookies cool on baking sheet about 10 minutes before transferring to rack. Cookies should feel firm enough to lift without bending.
Optional Icing
Beat icing ingredients until smooth. Drizzle or spread over cooled cookies.
