01 - Preheat the oven to 350°F. Line an 8x8-inch baking pan with parchment paper, leaving a 2-inch overhang on opposite sides for easy removal.
02 - Spread the oats, almonds, and walnuts in an even layer on a rimmed baking sheet. Toast in the preheated oven for 8-10 minutes, stirring halfway through, until lightly golden and fragrant. Remove and let cool for 5 minutes.
03 - In a small saucepan over low heat, combine honey (or maple syrup), peanut butter, and coconut oil. Stir continuously with a heat-resistant spatula until completely smooth and melted. Remove from heat and whisk in vanilla extract and sea salt.
04 - In a large mixing bowl, combine the toasted oats, nuts, pumpkin seeds, and shredded coconut (if using). Add the dried cranberries and chocolate chips, reserving 1 tablespoon of chips for topping. Toss to distribute evenly.
05 - Pour the warm peanut butter mixture over the dry ingredients. Using a sturdy spatula, mix thoroughly until all dry ingredients are evenly coated. Transfer the mixture to the prepared pan. Press down firmly and evenly using the back of the spatula or damp hands to pack the mixture tightly.
06 - Sprinkle the reserved chocolate chips over the surface and press gently to adhere. Refrigerate for at least 2 hours or until completely firm and set.
07 - Lift the bars from the pan using the parchment overhang. Place on a cutting board and cut into 12 equal bars. Store in an airtight container in the refrigerator for up to 1 week.
