High-protein apple and peanut butter overnight oats are honestly one of the best ways to start your day.
They’re creamy, crunchy, slightly sweet, and packed with all the good stuff your body needs in the morning. The combo of creamy peanut butter, tangy Greek yogurt, and juicy apples gives these oats the perfect balance of protein, fibre, and flavour. Plus, they’re ridiculously easy to prep—just mix everything the night before, pop it in the fridge, and wake up to a ready-made breakfast that tastes amazing and keeps you full for hours.
Why You’ll Love Them
• The ultimate make-ahead breakfast—prep once, enjoy all week!
• Full of protein and fibre to fuel your morning and support digestion.
• Deliciously creamy and naturally sweet, with a little crunch from fresh apple.
• Totally customisable—use your favourite apples or switch up the toppings.
Ingredients
• 2 small apples – I used Granny Smiths
• 180g porridge oats
• 500ml unsweetened soy milk (or your preferred milk)
• 180g plain Greek-style yogurt
• 4 tablespoons smooth natural peanut butter
• 2 tablespoons pure maple syrup
• 1 tablespoon vanilla extract
• ¼ teaspoon salt
• ⅛ teaspoon ground cinnamon
Lemon juice
Method
Step 1: Prep the Apples
Chop one of your apples into bite-sized pieces – sprinkle with lemon juice to stop browning
Step 2: Mix It All Together
In a medium bowl, whisk together the oats, soy milk, yogurt, 3 tablespoons of peanut butter, maple syrup, vanilla, salt, and cinnamon until smooth and creamy. Stir in your chopped apple.
Step 3: Chill Out
Cover your bowl or divide the mixture into jars, then refrigerate overnight—or for at least 8 hours. The oats will soak up all that creamy goodness while you sleep.
Step 4: Serve and Top It Off
In the morning, give your oats a quick stir and portion them out. Slice the second apple for extra crunch, swirl through the remaining peanut butter, and add your favourite toppings—berries, pumpkin seeds, and coconut flakes are my go-tos.
Final Touch
Think of these oats as your morning power-up. Each serving packs 20g of protein, 8g of fibre, and a healthy dose of good fats. You get long-lasting energy, stable blood sugar levels, and a happy gut—all while eating something that feels like dessert! They’re great cold straight from the fridge, or warm them gently if you fancy something cozier. I like making a few jars on Sunday night so breakfast is completely sorted for the week—zero effort, maximum yum.
