In a large bowl, combine brewed coffee, almond milk, honey, and cocoa powder. Stir until honey and cocoa powder are completely dissolved. If using collagen powder, add in as well and stir until dissolved. Taste for preferred sweetness, add additional honey or cocoa powder if desired.
Pour mixture into popsicle molds and freeze for at least 8 hours or overnight.If adding mini chocolate chips to bottom of pops, sprinkle them in once popsicles have set but before they are completely frozen.
Once frozen, run molds under warm water to help loosen and remove.
