In a small bowl, combine the ground chia seeds and water. Stir to combine and set aside. Also, preheat the oven to 350 °F/175 °C and line a baking sheet with parchment paper.
In a medium-sized bowl, add the ground sunflower seeds (or almond meal), granulated sugar of choice, cocoa powder, baking soda, salt, and espresso powder. Mix until there are no lumps.
Add nut/seed butter of your choice, coconut oil, vanilla extract, and the chia seed mixture. Stir (or blend, if using a food processor) until combined.
