01 - Line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a medium bowl, combine granola, honey (or maple syrup), and melted coconut oil until well incorporated.
03 - Press the granola mixture firmly and evenly into the bottom of the prepared pan to form a solid base layer.
04 - In a separate bowl, whisk Greek yogurt, honey (or agave), and vanilla extract until smooth and creamy.
05 - Spread the yogurt mixture evenly over the granola base using a spatula.
06 - Distribute mixed berries over the yogurt layer. Sprinkle chia seeds on top if using for added texture.
07 - Transfer the pan to the freezer and freeze for at least 4 hours, or until completely firm throughout.
08 - Use the parchment overhang to lift the frozen slab from the pan. Place on a cutting board and let rest for 5–10 minutes to soften slightly before cutting into bars.
