Moldy Muffins Recipe Notes and FAQ
Do I have to use blueberries?
No, blueberries are optional in this recipe, but they are loved by many in a breakfast muffin. You can leave them out, or use chocolate chips instead.

Do I have to use a blender?
A blender or food processor is highly recommended in this recipe. You want everything to be puréed, so you don’t end up biting into chunks of banana or spinach.

Do I have to use ripe bananas?
Yes, you definitely want to use ripe bananas. If you have bananas that aren’t quite ripe yet, you can place them in a paper bag overnight to speed up the ripening process.

Ew, mold?
These muffins are not really moldy. It’s a Halloween trick, silly! Don’t let the grody look fool you, these breakfast muffins are extremely yummy. Gross-looking treats are great for Halloween parties, zombie themes, Sesame Street (Oscar the Grouch) themes, or an April Fool’s Day joke.

Can I use sweetened applesauce instead?
This recipe calls for unsweetened applesauce, but if you only have sweetened, we can make it work. If you use sweetened applesauce, cut the brown sugar down to 1/2 cup.

How do I store these muffins?
Store these Halloween muffins in an airtight container on the counter for up to 3 days. We don’t want them to grow actual mold.
