Peel avocados and remove the pit, then place into a medium or large bowl.
Mash up the avocadoes until they’re a similar texture to mashed potatoes.
Add the rest of the ingredients to the bowl until mixed well.
Cover a 30 cm x 20 cm baking dish with parchment paper.
Pour ingredients from the bowl into the baking dish.
Place in the oven and bake for 35 minutes.
Remove from the oven and insert a toothpick in the center of the brownies. If the toothpick comes out clean, the dish is ready. If not, place back in the oven for a few more minutes and monitor progress.
Serve warm or let cool to room temperature and enjoy.
