You have 3 options, bake the dough immediately, chill the dough in the fridge, or freeze the dough. See the comparison picture above to see the outcomes and learn about the differences between each method.
Line baking sheets with parchment paper. If you are going to bake the cookies immediately, preheat the oven to 350 degrees F (177 C).
In a medium-large glass bowl, melt the butter in the microwave (only about 15 seconds at a time because mine exploded doing longer increments). Add the brown sugar, sugar, salt, espresso, vanilla, and egg and whisk very well until smooth. Sift in the cocoa powder (to prevent clumps), add the baking soda, and GF flour and whisk until completely smooth. Fold the chocolate into the dough using a spatula.
If you are baking the cookies immediately, scoop dough balls onto the lined baking trays making sure there's a good amount of space in between each so they won't bake into each other. Bake the cookies for 8-10 minutes or until the edges look more crisp than the center. Remove from the oven and let them cool for at least 5 minutes before enjoying!
If you are chilling the dough in the fridge, scoop dough balls onto the lined baking sheets (no need to distance them) and chill in the fridge for at least 30 minutes. At about the 20/25 minute mark, preheat the oven to 350 degrees F (177 C). Once the oven is fully heated, remove a baking tray from the fridge, arrange 12 dough balls (distanced) on the tray, and bake for 8-11 minutes or until at least the edges look fully baked and slightly crisp. Remove from the oven and let them cool for at least 5 minutes before enjoying!
If you are freezing the dough, scoop dough balls onto the lined baking sheets (no need to distance them) and chill in the freezer until solid (about 20-30 minutes). If you are not going to bake them today, transfer the dough balls to a container or sealable bag. If you are going to bake them today, after about 20 minutes chilling in the freezer, preheat the oven to 350 degrees F (177 C). Once the oven is heated, remove 12 dough balls from the freezer, arrange them (distanced) on a lined baking tray, and bake for 9-12 minutes or until at least the edges look fully baked and slightly crisp. Remove from the oven and let them cool for at least 5 minutes before enjoying!
