Preheat the oven to 350 F and line a muffin tin with 9 muffin liners.
Mash the banana in a medium-sized mixing bowl, then add in the eggs, beet carrot blueberry packet, avocado oil, and vanilla extract, and whisk to combine.
In a separate bowl, mix together the flour, oats, baking soda, baking powder, and cinnamon.
Fold the dry ingredients into the wet, and mix until thoroughly combined.
Add in the blueberries and mix until well incorporated.
Portion the batter evenly across the muffin liners, and bake for 20-25 minutes, or until a toothpick comes out clean.
Cool and serve immediately, or store in an airtight container in the refrigerator for up to 48 hours.
