Preheat the oven to 350℉. Butter a 9-inch square baking pan and then set aside.
In a medium bowl, add the flour, dairy-free melted butter, dairy-free milk, baking powder, ½ of a mashed banana, and hemp seeds (if using). Using a large spoon, mix to combine well.
Add the mixture to the greased 9-inch square baking pan. Spread evenly.
Use a fork to smash the fresh raspberries and then spread them evenly over the bottom crust layer.
In a separate medium bowl, combine the sugar and the remaining ½ of the mashed banana. Stir in the shredded coconut, melted coconut oil, and vanilla extract. Mix well until evenly blended.
Gently spread the sugar and coconut mixture on top of raspberry mixture in pan, being careful not to press too hard.
Bake for approximately 30 minutes, or until the top layer of the bars are golden brown.
Remove the pan from the oven and allow them to cool on the counter for 10 minutes. From there, place the pan in the refrigerator for 30 minutes. The bars will be easier to cut when chilled.
