Preheat the oven to 350 degrees.
In the bowl of an electric mixer, add the ½ cup salted butter, ¼ cup brown sugar, and ¼ cup maple syrup. Cream together on medium speed until light and fluffy.

Add the dry ingredients to the mixer bowl and mix on low speed until a dough forms.
Form the dough into a disk and wrap in plastic wrap. Chill in the refrigerator for at least 1 hour.
Remove the dough from the refrigerator and place on a floured surface. Roll the dough into a ¼ inch thick sheet. Use a pumpkin shaped cookie cutter or paper template and knife to cut out about 12 equal sized pumpkin shapes.
Transfer the shaped dough to a baking sheet lined with parchment paper, at least ½ inch apart.
Bake the cookies for about 12 minutes until the edges are golden brown.
Remove from the oven and transfer to a wire cooling rack. Let the cookies cool for at least 30 minutes.
Meanwhile, begin the icing by whisking together the 3 egg whites and ¾ cup granulated sugar on a double boiler set to medium-low heat. Cook for about 5 minutes until the sugar has dissolved, stirring frequently.
3 egg whites, ¾ cup granulated sugar
Add the egg mixture to the bowl of an electric mixer fitted with a whisk attachment. Add the 1 tsp vanilla extract, ½ tsp ground cinnamon, ¼ tsp cream of tartar, and 1 tsp salt then beat on medium-high speed until stiff peaks form.
1 tsp vanilla extract, ½ tsp ground cinnamon, ¼ tsp cream of tartar, 1 tsp salt
Fill a piping bag fitted with a 1 inch circle tip with the meringue. Pipe two circles of meringue on the two sides of the cookie.
Return the iced cookies to a baking sheet lined with parchment paper. Broil the cookies for about 5 minutes, checking every minute to make sure they don’t burn. The meringue should be toasted to a golden brown.
Remove the toasted cookies from the oven and let cool for about 15 minutes before serving.
