Supplies Needed

Preheat your oven to 350 degrees F and line a muffin pan with liners and set aside.

If you use frozen spinach, make sure to thaw and drain it. Use a paper towel to absorb the excess water.

Add the spinach, bananas, eggs, applesauce, vegetable oil, honey, brown sugar, and vanilla extract to a blender or food processor. Blend until all the ingredients are puréed.

Pour the mixture into a large mixing bowl.

Fold in the flour, baking powder, baking soda, and salt.

Add the blueberries to the mix and stir gently.

In a separate mixing bowl, mix the crumbly topping. Stir the flour, oats, brown sugar, butter, and a drop of green food coloring.

Pour the batter into the lined muffin pan and top with the moldy crumble.

Bake in the preheated oven for 20 minutes or until the center is fully-baked.

Remove from the oven and dust with powdered sugar.

Let the muffins cool and enjoy!

Moldy Muffins Recipe Notes and FAQ

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.
