Gently warm the honey and coconut oil in a small saucepan over low heat, stirring until just combined and shimmering, about 2-3 minutes. The mixture should smell sweet and nutty, with a smooth, glossy appearance.
Pour the warm honey and coconut oil mixture into a medium mixing bowl.
Add the sunflower seeds, rolled oats, dried cranberries, sesame seeds, and a pinch of salt to the bowl.
Stir vigorously with a spatula until all ingredients are evenly coated and sticky, about 2 minutes. The mixture should be thick and hold together when pressed.
Transfer the mixture into a parchment-lined 8x8 inch dish. Use the spatula or your fingers to press down firmly and evenly, creating a compact, 1.5-inch thick layer.
Let the mixture rest at room temperature for 10 minutes, then refrigerate for at least 2 hours or until firm and set.
Once firm, lift the entire block out of the dish using the parchment paper. Place on a cutting board and slice into 8-10 bars with a sharp, hot knife for clean cuts.
Store the bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. Wrap individually for portable snacks and enjoy!
