Start by adding your pitted dates to the food processor. Pulse until they form a sticky paste. This natural sweetener will bind the dry ingredients and provide moisture.
In a large bowl, combine the quick oats, protein powder, hemp seeds, and pumpkin seeds. Stir to evenly distribute the seeds and powder.
Add the almond butter, vanilla extract (if using), sea salt, and the date paste from the food processor to the dry ingredients. Mix well. Add water one tablespoon at a time, stirring after each addition, until the mixture comes together into a thick, moldable dough.
Spoon the mixture evenly into a mini muffin tin or silicone molds, pressing down firmly to compact the mixture. This ensures your protein cups hold their shape once chilled.
In a microwave-safe bowl, combine chocolate chips and coconut oil. Microwave in 30-second intervals, stirring in between, until smooth and melted. Alternatively, use a double boiler on the stove for a gentle melt.
Pour the melted chocolate over each protein cup, smoothing with the back of a spoon if needed. Sprinkle flaky sea salt on top for a flavor contrast if desired. Transfer the tin to the fridge and chill for at least 1 hour, or until the chocolate hardens.
Pop the protein cups out of the molds and enjoy immediately, or store them in an airtight container in the fridge for up to a week.
