Preheat your oven to 350°F (180°C). Line an 8 or 9 inch (20 or 23 cm) square baking pan with parchment paper, leaving some overhang on the sides for easy removal later.

If making beetroot puree from scratch: Peel and chop 1-2 whole beetroots. Add them to a small pot of boiling water and cook for 5-10 minutes until tender. Drain, reserving some of the cooking water. Transfer the cooked beetroot to a food processor and blend until smooth. If it's not breaking down easily, add 1-2 tablespoons of the reserved cooking water (or some of the dairy-free milk from the ingredients) and blend again.

In a medium-sized bowl, combine all the dry ingredients: flour, coconut sugar, cocoa powder, ground chia or flax seeds, baking powder, baking soda, and salt (if using). Whisk everything together until well mixed and no lumps remain.

Add all the wet ingredients to the bowl with the dry ingredients: beetroot puree, melted vegan chocolate, oil, dairy-free milk, and vanilla extract (if using). Stir everything together until just combined. The batter will be quite thick - this is normal.

Transfer the brownie batter to your prepared baking pan, using a spatula to spread it evenly and smooth the top. Bake in the preheated oven for 15-20 minutes. For fudgier brownies, aim for the shorter baking time; for cakier brownies, bake a bit longer. The brownies are ready when the surface feels dry to the touch but a skewer inserted comes out with some moist crumbs attached.

Allow the brownies to cool completely in the baking pan. They will continue to set as they cool, so be patient even though they smell amazing!

While the brownies are cooling, make the frosting. Add the avocado, cocoa powder, pitted dates, and 1 tablespoon of maple syrup to a food processor. Process until completely smooth, stopping to scrape down the sides as needed. Taste and add more maple syrup if you'd like it sweeter, blending after each addition.

Once the brownies are completely cool, spread the avocado chocolate frosting evenly over the top. Use a sharp knife to cut the brownies into 16 squares. For the cleanest cuts, wipe the knife with a damp cloth between slices.
