Preheat the oven to 180c/350f.
Add all the ingredients (except for the flour, cacao and baking powder) to a blender and blend until smooth.
In a large bowl stir together the flour, cacao and baking powder, then pour over the veggie mix and stir to combine.
Spray/grease/line a muffin tray then evenly spread the mix between the 24 holes. Top with any pumpkin seeds or choc chips.
Place in the oven and bake for 20-22 minutes until cooked (notes below).
Remove from the oven and allow to cool for 5 minutes before gently removing from the tin using a spoon and leave to cool on a cooling rack, they will firm up as they cool.
Enjoy!
To make these as a Brownie:
Follow the steps above, but instead of adding the batter to a muffin tin, pour into a brownie tin (ours measures 26x20cm), then bake in the oven for 27-30 minutes until a toothpick comes out clean.
Store in an airtight container on the bench for 2 days, in the fridge for 5 days or freezer for up to 2 months.
