This haunted black smoothie is my go-to when I want something fun and festive for Halloween. The rich purple-black color comes straight from juicy blackberries and a touch of black food coloring. Creamy Greek yogurt makes it filling enough for breakfast or a snack while banana and almond milk bring mellow sweetness.
The first time I served this to friends on Halloween everyone loved the eerie look and delicious flavor. Now it’s a tradition at our house before trick-or-treating.
Ingredients
- Blackberries: plump ripe ones create the deep berry flavor and natural color boost fresh or frozen both work
- Banana: gives sweetness and smooth texture make sure it is ripe for the best taste
- Greek yogurt: turns the smoothie creamy and adds protein use thick plain yogurt for texture
- Almond milk: helps thin everything into a drinkable consistency choose unsweetened for less sugar
- Black food coloring: delivers a dramatic color just a few drops amp up the spooky look use a gel or natural food dye for best results
Step-by-Step Instructions
- Blend the Ingredients:
- Place blackberries banana Greek yogurt almond milk and a few drops of black food coloring in a blender. Start with two or three drops of food coloring and add more if needed to get the perfect dark hue.
- Smooth It Out:
- Blend everything on high speed for one to two minutes. Stop and scrape down the sides if you see any fruit pieces. Blend again until totally smooth and creamy with no lumps left at all.
- Taste and Adjust:
- Sample your smoothie. If you want a deeper black color add another drop or two of food coloring and blend again. If you want it a touch sweeter toss in another half of a banana or a drizzle of honey.
- Serve Immediately:
- Pour the smoothie into two glasses. Garnish with a few blackberries or spooky decorations if you like. Serve right away for the best creamy consistency.

Greek yogurt is my favorite for this because it adds lots of creaminess and a little tang. My nieces love swirling whipped cream on top for an extra festive touch at our Halloween breakfast.
Storage Tips
Smoothies always taste best fresh but you can store leftovers in the refrigerator for up to one day. Give it a good shake or stir if it separates. If making ahead for a party blend just before serving so the texture stays thick and creamy.
Ingredient Substitutions
Use coconut yogurt for a dairy free version or oat milk instead of almond milk. Frozen blackberries give an extra thick texture while fresh berries make it a bit lighter. If you want a sweeter smoothie try adding a Medjool date or maple syrup.

Serving Suggestions
Pour this smoothie into clear glass bottles and add paper straws for a party look. Add spooky eyes or gummy worms on top for a Halloween breakfast bar. I sometimes freeze the smoothie in popsicle molds for a chilly treat with a mysterious twist.
A Bit of Spooky Smoothie History
Fruit based Halloween drinks have become a huge trend for October parties. The tradition started with simple berry smoothies dyed with food coloring. I have seen versions inspired by witches elixirs and mad scientist potions all meant to wow your guests and spark creative fun.
