Step 1

Preheat the oven to 375F and line a large baking sheet with parchment paper.

Step 2

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

Step 3

Slice 1 tablespoon of butter from the 1 cup of room temperature butter and place that tablespoon into a small dish. Place the rest of butter into the mixing bowl of a hand or stand mixer with the paddle attachment.

Step 4

Measure out 1 cup of light brown sugar and remove 1 tablespoon. Place that tablespoon into the dish of 1 tablespoon of butter and add the remaining brown sugar to the large mixing bowl.

Step 5

Now add the granulated sugar to the large mixing bowl and mix on medium-high speed until smooth and lightened in color (about 2 minutes of mixing).

Step 6

Scrape down the bowl and add in the maple syrup, egg, and vanilla. Mix again on medium-high speed for about 1 minute.

Step 7

Pour in the dry ingredients and mix to combine. Then use a rubber spatula to mix the dough by hand, scraping down the sides and bottom of the bowl to ensure everything is well combined.

Step 8

To the small dish with the 1 tablespoon of butter and 1 tablespoon of brown sugar, add the rest of the spiced maple butter ingredients and stir to combine.

Step 9

Plop small amounts of the butter throughout the cookie dough. Using a rubber spatula, gently fold the dough to disperse the butter into ribbons. Careful not to over mix.

Step 10

Using a large 2 oz cookie scoop (or ¼ measuring cup) scoop the dough and roll in a small bowl of the cinnamon sugar.

Step 11

Place 3-4 cookies on the large baking sheet and bake for 6 minutes.

Step 12

After 6 minutes, open the oven door and drop the pan against the oven rack about 3 times. Continue to bake for another 2 minutes. After those 2 minutes, repeat the slamming process. Then bake for another 2 minutes, then slam again. Then bake for a final 2 minutes and drop the pan one final time for a total of 12 minutes baking.

Step 13

Allow the cookies to cool and continue baking the rest of the batch. Once all the cookies have baked, make the icing.

Step 14

Whisk together the melted butter and maple syrup, followed by the powdered sugar. Pour the icing into a piping bag or a sandwich bag and snip off a very tiny corner.

Step 15

Drizzle over the cooled cookies and enjoy!
