Gather all your ingredients: seeds, honey, coconut oil, oats, and dried fruit. Measure everything before starting; this keeps things smooth.
Line a 9-inch square pan with parchment paper, allowing some overhang for easy removal.
In a large mixing bowl, combine the sunflower seeds, chia seeds, oats, dried cranberries, and salt. Stir well until evenly distributed and the mixture looks cohesive.
In a small saucepan over low heat, gently melt the honey and coconut oil together. Stir constantly until the mixture is smooth and fragrant, about 2-3 minutes.
Pour the warm honey and coconut oil mixture over the dry ingredients in the bowl. Use a spatula to fold everything together until the mixture is sticky and well coated.
Transfer the mixture into the prepared pan. Use the back of a spatula or a pressing tool to firmly press the mixture into an even layer—pressing well helps the bars hold together.
Let the pressed mixture sit at room temperature for about 10 minutes, then transfer the pan to the fridge. Chill for at least 2 hours until the mixture is firm and set.
Once chilled and firm, lift the mixture out of the pan using the parchment overhang. Place on a cutting board and slice into bars or squares with a sharp knife. Dip the knife in warm water and wipe dry between cuts for cleaner edges.
Arrange the bars on a plate or store in an airtight container. Keep refrigerated for up to a week, or freeze for longer storage. Serve slightly chilled or at room temperature to enjoy the chewy, crunchy texture.
