Halloween Drink Recipes with MYOM
Three spooky vegan drinks, one creamy oat base. These non alcoholic Halloween drink recipes turn MYOM Original Oat Drink Premix into green Monster Matcha, golden Mango Mayhem and a blueberry Blue Moon shake. Blend your favourite, chill it and pour over ice.
Each recipe uses one 130g pouch and makes up to 1 litre, or four 250ml servings before ice. The blender is the standard method; Monster Matcha and Mango Mayhem also have Shake to Make options below.
The oat drink base for your Halloween shakes
MYOM Original Oat Drink Premix is a pouch of oat blend that you turn into a fresh oat drink by adding water. Here, it goes straight into the blender with the other ingredients, so there is no need to make a separate bottle first.
The MYOM Starter Bundle contains four 130g pouches and a reusable large glass bottle. That gives you a pouch for each recipe, plus one for your next creation. See the MYOM Starter Bundle

Before you blend
Use a blender with enough capacity for the ingredients and room for them to move. Start with the water quantity listed. You are making up to 1 litre of finished drink, not adding 1 litre of water to the recipe. If you are making in the bottle, leave room for shaking.
MYOM Monster Matcha

An iced matcha latte made with MYOM Original Oat Drink Premix. Smooth, green and ready for its monster moment. Keep the syrup optional and sweeten to your taste.
Makes: Up to 1 litre | Four servings | Serve chilled over ice
Ingredients
- 130g MYOM Original Oat Drink Premix
- 5–6g matcha powder, approximately 2½–3 teaspoons
- Approximately 800ml cold water, plus extra to top up the bottle
- 15–30ml maple syrup or agave syrup, optional
- Ice, to serve
Blender method
- Add the premix, matcha powder, 800ml cold water and any optional syrup to the blender.
- Blend for 30 seconds, or until smooth and free of matcha lumps.
- Transfer to a clean MYOM bottle or suitable container, leaving room to shake. Chill, shake briefly and serve over ice.
Shake to Make alternative
Whisk the matcha with 50ml warm water at around 70–80°C until smooth. Add approximately 600ml cold water to a clean large bottle, then the matcha mixture, premix and optional syrup. Secure the lid and shake vigorously for 30 seconds. Check the volume in a measuring jug, top up with cold water to taste. Chill before serving. The warm water replaces part of the cold water; it is not an extra 50ml on top of the final litre.
MYOM Mango Mayhem

A golden mango oat drink smoothie with a little vanilla. Fresh ripe mango brings the fruit to the blender version; smooth mango purée makes the Shake to Make option easy.
Makes: Up to 1 litre | Four servings | Serve chilled over ice
Ingredients
- 130g MYOM Original Oat Drink Premix
- 150g fresh ripe mango, weighed after peeling and removing the stone
- ½ teaspoon vanilla extract
- Approximately 700ml cold water, plus extra to top up to taste
- 10–20ml maple syrup or agave syrup, optional
- Ice, to serve
Blender method
- Add the premix, fresh mango, vanilla, 700ml cold water and any optional syrup to the blender.
- Blend for 30 seconds, or until the mango is completely smooth. Blend longer if needed.
- Transfer to a clean MYOM bottle or suitable container, leaving room to shake. Chill, shake briefly and serve over ice.
Shake to Make alternative with mango purée
Replace the 150g fresh mango with 120g smooth mango purée. Add approximately 600ml cold water to a clean large bottle, followed by the premix, purée, vanilla and optional syrup. Secure the lid and shake vigorously for 30 seconds. Check the volume in a measuring jug, top up with cold water to 1 litre and mix again. Chill and shake before serving. Use purée only for this method: fresh mango pieces need a blender.
MYOM Blue Moon

Blueberries, banana and vanilla vegan protein powder meet MYOM Original Oat Drink Premix in this Halloween shake. Blue spirulina adds colour, although blueberries can pull the finished drink towards purple. The exact shade varies with your ingredients.
Makes: Up to 1 litre | Four servings | Serve chilled over ice
Ingredients
- 130g MYOM Original Oat Drink Premix
- 100g frozen blueberries
- 25–30g vanilla vegan protein powder
- ½–1 teaspoon food-grade blue spirulina powder
- ½ banana, ideally frozen
- Approximately 700ml cold water, plus extra to top up to taste
- 1 teaspoon maple syrup, optional
- A handful of ice, plus extra to serve
Blender method
- Add the premix, blueberries, protein powder, blue spirulina, banana, 700ml cold water, a handful of ice and any optional syrup to the blender.
- Blend for 30 seconds, or until completely smooth. Blend longer if needed to break down the frozen fruit.
- Transfer to a clean MYOM bottle or suitable container, leaving room to shake. Chill, shake briefly and serve over ice.
