Whisk the flour, cinnamon, baking powder, and salt together in a medium bowl. Set aside.

In a large bowl using a handheld or a stand mixer fitted with a paddle attachment, beat the butter and sugar together on high speed until completely smooth and creamy, about 2 minutes. Add the egg, maple extract, and vanilla extract and beat on high speed until combined, about 1 minute. Scrape down the sides and bottom of the bowl and beat again as needed.

Add the dry ingredients to the wet ingredients and mix on low until combined. Dough will be a bit soft. If the dough seems too soft and sticky for rolling, add 1 more Tablespoon of flour.

Divide the dough into 2 equal parts. Place each portion onto a piece of lightly floured parchment paper or a lightly floured silicone baking mat. With a lightly floured rolling pin, roll the dough out to about 1/4-inch thickness. Use more flour if the dough seems too sticky. The rolled-out dough can be any shape, as long as it is evenly 1/4-inch thick.

Lightly dust one of the rolled-out doughs with flour. Place a piece of parchment on top. (This prevents sticking.) Place the 2nd rolled-out dough on top. Cover with plastic wrap or aluminum foil, then refrigerate for at least 1-2 hours and up to 2 days.

Once chilled, preheat oven to 350°F (177°C). Line 2-3 large baking sheets with parchment paper or silicone baking mats. Carefully remove the top dough piece from the refrigerator. If it’s sticking to the bottom, run your hand under it to help remove it. Using a cookie cutter, cut into star shapes. Transfer the cut cookie dough to the prepared baking sheet. Re-roll the remaining dough and continue cutting until all is used. Repeat with 2nd piece of dough. (Note: It doesn’t seem like a lot of dough, but you get a lot of cookies from the dough scraps you re-roll.)

Before baking, top with sprinkles. Use a spoon to press the sprinkles into the cookies so they stay secure on top.

Bake for 11-12 minutes, until lightly browned around the edges. If your oven has hot spots, rotate the baking sheet halfway through bake time. Allow to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before dipping into chocolate.

If using, melt the chopped white chocolate in the microwave in 20 second increments, stirring after each until completely melted. Dip the cookies into the white chocolate and allow chocolate to set completely at room temperature or in the refrigerator.
