Best Vegan Blueberry Muffins

These are very rich and decadent, thanks to the secret ingredient (avocado.) There is a large amount of sugar in them as well: both granulated and brown. So, they are delicious but you can't eat that many. Which is probably a good thing. I made these as mini-muffins instead of regular muffins, which worked well. The recipients and I agreed that smaller was better with this recipe. The recipe made 36 mini muffins.

Equipment needed: 3 12-cup mini-muffin tins, potato masher (optional, for the avocado)
