Scale: Place a large mixing bowl on the scale. Tare the bowl then add flour, sugar, baking powder, salt, and spices.(Remember to use the scale’s tare function to remove the weight of the bowl and previous ingredients to only weigh the current item added)
Stir: Stir dry ingredients together.
Add butter: Butter should be very cold. Cut butter in half then cut each half into eight pieces. Add cubes of butter to the dry mixture. Use two forks or a pastry cutter to cut butter into smaller pieces and distribute through the dough. Mixture should become crumbly and sandy with butter distributed throughout mixture. Some big pieces are okay, no bigger than a pea. If your butter is getting too warm, put mixture into freezer for 1 to 3 minutes to firm up butter.
Mix: Add chilled milk, molasses, and the egg. Stir to combine so that there are no longer any sections of dry flour, don’t overmix. Don’t add extra milk, dough takes time to come together. It will likely become warm, chill dough in the fridge for 10 to 30 minutes before shaping.
Optional: Dough can be covered and fermented in fridge for up to 24 hours before shaping.
Prepare baking sheets: Place 2 pieces of parchment paper on 2 different baking sheets.
Preheat oven: Preheat oven to 400 degrees F, unless you plan to chill the dough after shaping to make them later.
Shape: To shape into the mini scones, lightly flour your work surface. Place dough onto work surface and gently pat top and side into a square-ish shape before rolling with a rolling pin. Roll dough into an 8-inch square. The dough should be about 1-inch thick.
Divide: Use a large, sharp knife to cut the dough into fourths, if the dough is sticking to the knife, lightly flour it before each cut. Then, cut each fourth into fourths. There are now 16 cut squares. Cut each square in half diagonally to create the mini scone triangles. Place the cut scones onto the prepared parchment papers about 2 inches apart. If the dough became too warm, cover dough and chill before baking or these can be made ahead of time and chilled.
Bake: Bake scones at 400 degrees F for 12 to 16 minutes until the top is puffed and matte (no longer shiny) with golden brown edges.
Cool: Let cool for 10 to 20 minutes until they are slightly warm but no longer hot.
Icing: While the scones are cooling, make the icing. Whisk eggnog icing ingredients together until it’s a thick drizzling consistency--thicker than molasses. Scoop a 1-2 teaspoons onto each scone, gently spread with a back of a spoon or butter knife. Repeat with the rest of the scones.
Serve: These can be served and enjoyed right away or you can let them sit and cool completely for 15 to 30 minutes for the icing to harden.
