A plant-based oat drink that is not only vegan and high in protein but develops natural sweetness and depth through the combination of blueberries and vanilla. The oats are used not only as a base but also give the drink a slightly grainy texture reminiscent of porridge—perfect for cold days or as a refreshing variation with ice. Maple syrup rounds off the flavor without dominating. A drink that adapts: served warm as a breakfast substitute, cold as a shake, or even as a cocktail base.
And this is what you need for the Blueberry-Vanilla Oat Drink
80 g oats (fine or coarse variety)
1 litre water (filtered, for better taste)
150 g blueberries (fresh or frozen, unthawed)
2–3 tablespoons maple syrup (to taste)
1 teaspoon vanilla extract (or the seeds of half a vanilla pod)
1 pinch of salt (enhances the sweetness)
What matters
The trick is in the straining: Many recipes leave the oats simply in the blender, but the result quickly becomes mealy or lumpy. A fine sieve or kitchen towel removes the coarse particles without losing the creamy character. For an especially smooth texture, you can press the oat milk through a straining cloth with the blueberries before mixing. Another bartender tip: Frozen blueberries give the drink a slightly icy texture without needing additional ice—ideal for a quick, cold variation.
Variations
- Blueberry-Vanilla Oat Shake — For a thicker consistency, add 1 banana or 100 g Greek yogurt (vegan alternative: coconut yogurt) to the blender. Refine with a pinch of cinnamon or cardamom—particularly well-suited to vanilla.
- Oat Drink with Rum Aroma — For an adult variation, stir in 3 cl brown rum or bourbon whiskey after the drink has cooled. The alcohol rounds off the sweetness and gives the whole thing a warm, caramel-like note. Garnish with a cinnamon stick.
- Green Oat Drink — Instead of blueberries, mix in a handful of spinach or kale—the vanilla overpowers the grassy aroma, and the drink takes on a vibrant green colour. Finish with a little ginger juice or lemon juice for freshness.
Frequently Asked Questions
Can I prepare the drink without a blender?
Yes, but the texture will be coarser. Pour hot water over the oats and let steep for 10 minutes, then strain through a sieve. Crush the blueberries separately with a fork and stir in. The taste remains similar, but the drink is less creamy.
How long does the oat drink keep in the fridge?
Max. 2 days—oat milk tends to separate or turn sour. For longer storage, prepare the mixture without blueberries and add them just before serving. Alternatively, freeze in portions and thaw as needed.
Why does the oat flake out when heated?
This happens if the temperature is too high or the drink is boiled for too long. Always heat on medium heat while stirring—max. to 70 °C. For extra safety, heat only half the liquid and stir in the other half cold.
Can I use other fruits?
Yes, almost any berries or ripe fruits like peach or mango work. Important: The fruits should be sweet, as oats themselves have little flavour. For tart fruits like raspberries, use a little more maple syrup.
