Preheat your oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving some overhang for easy removal later.
In a large mixing bowl, combine the rolled oats, shredded coconut, sunflower seeds, and chopped nuts. Mix well.
In a separate microwave-safe bowl, add the almond butter, honey (or maple syrup), and vanilla extract. Heat in the microwave for about 30-45 seconds until melted and easily mixed. Stir until smooth.
Pour the almond butter mixture over the dry ingredients. Use a spatula to mix thoroughly, ensuring everything is evenly coated.
Fold in the dark chocolate chips until just combined.
Press the mixture into the prepared baking pan, spreading it evenly and pressing down firmly with the back of a spatula to ensure it holds together.
Bake for 20-25 minutes, or until the edges are lightly golden. Allow to cool in the pan for 10-15 minutes before transferring to a wire rack to cool completely.
Once cooled, lift the granola bars out using the parchment paper. Cut into squares or rectangles.
Notes
Arrange the bars on a platter and sprinkle with extra shredded coconut and chocolate chips for decoration.
