What's better than oat milk? Not much. But what about oats covered in oat milk aka overnight oats? This plant-based lemon blueberry version is made with Overherd oat milk powder, layered with a blueberry yogurt mixture, and left overnight to do its thing. Prep it the night before. Wake up. Breakfast is done.
Ingredients
Oat layer 80g rolled oats 20g Overherd oat milk powder 170ml water 1½ tbsp maple syrup 1 tsp lemon juice ½ lemon, zested Pinch of salt Blueberry layer 90g blueberries 140g Greek-style plant-based yogurt 1 tsp maple syrup 1 tsp lemon juice To serve 120g fresh blueberriesMethod
Make the layers
1 Mix all the oat layer ingredients together in a bowl until fully combined. Refrigerate for one hour.
2 Mix all the blueberry layer ingredients together in a separate bowl until combined.
Assemble
3 Prepare two glass jars. Divide each layer mixture into 4 equal parts.
4 Spoon 1/4 of the blueberry layer into the bottom of each jar, followed by 1/4 of the oat layer, then scatter over half the fresh blueberries. Repeat with the remaining layers on top.
5 Cover and refrigerate overnight. Serve cold straight from the jar.
Tips
Rest the oat layer first Refrigerating the oat layer for an hour before assembling lets the oats start absorbing the liquid. It gives a better texture in the final jar rather than a loose, watery layer.
Use wide-mouth jars Wide-mouth mason jars make layering easier and look better when serving. They're also easier to eat from directly, which matters at 7am.
Make it the night before The longer it sits, the better the texture. Minimum overnight but up to 2 days in the fridge works well if you want to prep ahead for the week.
FAQ
Can you make overnight oats with oat milk powder? Yes, and it gives a creamier result than carton oat milk. Adding Overherd powder directly to the oat layer means the mixture is already at the right concentration when it goes in the jar. No separate milk to measure or a carton to open at 10pm.
How long do overnight oats keep in the fridge? These overnight oats will keep for up to 2 days in the fridge when covered. The texture is best on the first morning but still good on day two. The blueberry layer may release a little more liquid over time, so give it a stir before eating if needed.
Can I use frozen blueberries instead of fresh? Sure! Frozen blueberries work in the blueberry layer and will thaw overnight in the fridge. For the blueberries added to serve, fresh is better for texture and appearance, but frozen defrosted ones are fine if that's what you have.
Serving suggestions
01 Classic lemon blueberry The recipe above. Fresh blueberries on top, eaten cold from the jar. A proper breakfast that required zero effort this morning.
02 With granola on top Add a handful of granola just before serving for crunch. Don't add it the night before or it goes soggy which is a sad way to start the day.
03 Desk breakfast The jar goes straight in your bag. No bowl needed, no washing up at work. The overnight oats have officially solved mornings.
04 With a drizzle of maple A small drizzle of maple syrup on top just before eating adds a little extra sweetness if needed.
Variations
Strawberry and vanilla Swap blueberries for strawberries and add ½ tsp vanilla extract to the oat layer. A softer, more classic overnight oats flavour.
Mango and lime Replace blueberries with mango chunks, swap lemon for lime throughout, and add a tablespoon of chia seeds and an extra 30ml of water to the oat layer. Tastes like somewhere warmer than wherever you're eating it.
Chocolate and raspberry Add 1 tsp cocoa powder to the oat layer and swap blueberries for raspberries. The tartness of the raspberry works well against the chocolate.
Extra creamy Increase the Overherd powder to 30g in the oat layer for a richer, creamier result. Good if you find overnight oats a bit thin.
