- In a bowl, whisk together the flour, cinnamon, ginger, all spice, baking soda, and salt.
- In a separate bowl,beat the butter and brown sugar together until very light and fluffy, wiping down the bowl as needed. Beat in the egg until fully and smoothly incorporated. Beat in the treacle and vanilla extract until evenly incorporated.
- Fold in by hand until all ingredients are evenly incorporated.
- Divide dough in half and shape each half into a rough square on a piece of plastic wrap. Wrap and refrigerate until firm, about 3 hours.
- Preheat oven to 350ºF and line a baking sheet with parchment paper. Working with one half of dough at a time, remove from fridge and transfer to a sheet of parchment dusted generously with flour. Dust the top of the dough with flour and roll out to 1/4″ thick, adding more flour as needed. Cut out gingerbread and transfer to prepared baking sheet, leaving space between each cookie. Bake in preheated oven for 7-9 minutes, until cookies look dry on top but are still a bit soft to the touch in the center.*
- Meanwhile, ball up the scraps from the first half of dough, wrap, and refrigerate. Repeat the above process with the second half of dough, making sure to use a cool baking sheet for each new batch of cookies.**** Finally, combine all dough scraps together and roll, cut, bake, and repeat as/if needed until all cookies are made.
- Cool cookies on baking sheet for 15-20 minutes, or until firmer, before moving to a wire rack to cool completely. Store in an airtight container at room temperature. Dust with confectioner’s sugar before serving, if desired.
The dough can be refrigerated for up to a few weeks to bake later. If you do keep the dough in the fridge for more than a few hours, let it sit at room temperature for just a few minutes before rolling out to prevent cracking.
***8 minutes always seems to be the perfect baking time for me, but if you want a more firm cookie, lean towards 9 minutes or so. If you use a different sized cookie cutter, the baking time may vary, so look for the visual cues described in the recipe.
****If you only have one or two baking sheets, you can cool them down quickly by running cold water over them. Dry before using again.
