Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper.

In a large mixing bowl, combine rolled oats, chopped almonds, and sunflower seeds. Add honey, melted coconut oil, vanilla extract, and salt. Mix until sticky.

Transfer the mixture into the prepared baking pan and firmly press it down evenly.

Bake for 15-20 minutes until edges are light golden color.

In a saucepan, combine mixed berries, chia seeds, and maple syrup over medium heat and stir for 5-7 minutes until thickened.

Spread the warm berry topping over the baked base evenly.

Allow the bars to cool completely in the pan, about an hour.

Once cooled, lift out using parchment overhang and cut into squares.
