1. Add all brownie layer ingredients (almonds, pumpkin seeds, pitted and soaked dates, nut butter, cacao powder, vanilla) to a food processor and pulse until a dough forms.
2. In a small bowl, mix chocolate mousse ingredients (yogurt of choice, cacao powder; protein powder or maple syrup/honey are optional).
3. Press the brownie dough into a silicone mold tray or line a muffin pan with liners.
4. Add the mousse to the brownie layer, then top with melted chocolate (1 chocolate bar melted with 1 tsp oil).
5. Freeze for 1-2 hours. Enjoy!
