Heat a skillet over medium-low heat and add the sunflower seeds. Toast for 3–5 minutes until lightly browned and fragrant. Then add sesame seeds and toast for an additional minute.

In a food processor, combine half of the toasted sunflower seeds with soaked pitted dates, optional hemp seeds, tahini, honey, cinnamon, cardamom, and a pinch of salt. Blend until sticky and well-combined.

Transfer the mixture to a mixing bowl and stir in the reserved toasted sunflower seeds.

Line an 8x5-inch tray with parchment paper, press the mixture into the tray evenly, and drizzle with melted chocolate topping if desired.

Chill the tray in the refrigerator for about 2 hours or in the freezer for 30 minutes until firm.

Lift out using parchment paper and cut into squares. Enjoy your bars!
