Preheat the Oven: Preheat your oven to 350°F (180°C) and line a baking dish (approximately 8x8 inches) with parchment paper, leaving some overhang for easy removal.

Prepare the Bottom Layer:

o In a food processor, blend the cooked and peeled beetroot with the bananas until smooth and well combined.

o Add the oats, maple syrup, and nuts to the beetroot-banana mixture. Pulse until everything is well combined and you have a thick, sticky mixture.

o Press the mixture firmly into the prepared baking dish, creating an even layer for the base.

Prepare the Top Layer:

o In a large bowl, combine the roughly chopped nuts, mixed berries, oats, and seeds.

o Drizzle with the maple syrup and plant milk. Stir everything together until well mixed and the oats and seeds are coated.

Layer the Top Mixture:

o Spread the berry and nut mixture evenly over the bottom layer in the baking dish. Press down gently to ensure it sticks to the base layer.

Bake the Energy Bars:

o Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the top is golden and the bars are firm to the touch.

o If using frozen berries, you may need to bake for an additional 5-10 minutes to ensure the bars set properly.

Cool and Slice:

o Remove the dish from the oven and allow the bars to cool completely in the pan.

o Place the bars on a cutting board and slice into squares or rectangles.

Serve and Store:

o Enjoy the bars immediately, or store them in an airtight container in the refrigerator for up to a week. These bars also freeze well for longer storage.
