Make the macaron shells:

1. Prepare a baking sheet with a silicone baking mat (or if you have enough, prepare 2 baking sheets).
2. Using a fine mesh sieve over a large mixing bowl on a scale, sift almond flour until you reach 137 grams. Discard any large pieces of almond flour. Repeat with the confectioners’ sugar (117 grams). Whisk together the almond flour, confectioners’ sugar, cinnamon, ginger, and cloves until very well-combined. Set aside.
3. Add egg whites to the bowl of your stand mixer. Using a whip attachment, beat the mixture, starting on low. Once soft peaks have been formed (about 2 minutes), slowly add the sugar and increase the speed to medium. Once medium peaks are achieved, increase the speed to high. Beat on high until stiff peaks have formed, about 2 minutes. Add in the brown food coloring and beat until just combined.
4. Remove the bowl from the stand mixer and place a sieve over top. Pour the dry mixture into the sieve, then sift the dry ingredients into the meringue.
5. Use a rubber spatula to fold the dry ingredients into the meringue. Be careful not to overmix and over-deflate the meringue. The mixture is ready to be piped when it ribbons off your spatula. The batter, when lifted with a spatula, should keep flowing off the spatula in ribbon shapes nonstop, without drizzling off too quickly. If it is coming off in large V shaped chunks it needs to be folded more. My preferred test is the figure 8 test: If you can lift some batter up and use it to draw several figure 8’s without the stream breaking, it is ready!
6. Add batter to a piping bag with a medium to large sized round tip (I recommend a large 1/2-inch top). Pipe 1 to 1 ½-inch small circles of batter onto the prepared baking sheet. Make sure the piping bag is held straight up and perpendicular to the baking sheet.
7. After you’ve piped all the macarons, gently tap the baking sheet multiple times against the counter to remove any air bubbles from the macarons. If some air bubbles still remain, use a toothpick to gently poke them out.
8. Preheat oven to 300°F. While the oven is preheating, allow the macarons to sit and form a “skin”. This “skin” should form anywhere from 8 minutes to an hour. You know the macarons are ready to be baked when you can touch them lightly without having the batter stick to your finger. Keep checking them periodically to see if they have formed a skin.
9. Bake for 15-20 minutes. Check at 15 minutes, and if they are not ready then keep checking every minute. The macarons are ready when the tops are firm and do not move around their base at all. Allow the macarons to cool completely before attempting to remove them from the silicone mat.

Decorate the macaron tops (optional):

1. Melt the white chocolate in a double broiler or in the microwave.
   • On the stove: Bring 2 inches of water to a low simmer in a saucepan over medium-low heat. Then, turn the heat to low and place a medium heatproof bowl on the mouth of the pot. Make sure that there is a gap of a few inches in between the bottom of the bowl and the water (You can also place a bowl on a steamer attachment on top of your pot). Add the chocolate and stir constantly as it melts. Stir until the chocolate is completely smooth and melted. This should take a few minutes.
   • In the microwave: Place a medium heatproof bowl of chocolate into the microwave and microwave in 30 second intervals. Remove the bowl at each interval and stir well. Repeat until the chocolate has completely melted. Stir until completely smooth.
2. Drizzle the tops of half of the macarons with the melted white chocolate then sprinkle with gingerbread men sprinkles. Set aside to harden. To speed things up, set aside in the fridge.

Make the molasses buttercream:

1. In a large mixing bowl, add the butter, confectioners' sugar, molasses, and vanilla. Beat with an electric hand mixer until well combined, creamy, and slightly paler in color.

Assemble the macarons:

1. Place the buttercream into a piping bag fitted with a large ½ inch round tip.
2. Pipe the buttercream onto the bottom half of the macaron shells (undecorated half).
3. Top each bottom half with the macaron tops (these are the decorated tops if you opted to add the toppings).
4. Place into the fridge overnight to mature and meld together for the best results.
