Ingredients in this recipe:
Please see the recipe card further along in the post for exact quantities of ingredients and the full method.
Peanut Butter – for the best flavour, use natural unsweetened peanut butter. Smooth or crunchy works well in this recipe. The peanut butter adds great flavour and works so well with oats, just like my Peanut Butter Porridge.
Milk – use milk of your preference. I like to use almond or oat milk, but soy milk works just fine. You can use dairy milk if you don’t need the oats to be vegan.
Maple Syrup – we use a small amount to sweeten the oatmeal. If you prefer more sweetness, you could add extra maple syrup when serving.
Oats – use old-fashioned Rolled Oats for this recipe. They are a budget-friendly whole grain, complex carbohydrate and a good source of dietary fibre.
Chia seeds – use black or white. These little seeds are a nutritional powerhouse being a complete protein, a good source of omega-3 fatty acids as well as being rich in dietary fibre.
Baking powder – is a raising agent which helps lift and lighten the oatmeal.
Salt – a little sea salt helps to enhance the flavours.
Greek yoghurt – optional, for serving. We make a peanut butter yoghurt to top the oatmeal with. You can use coconut yoghurt or another dairy-free alternative to keep the recipe vegan if needed.
Coconut oil – to lightly grease the baking dish.

Tips for success and FAQs:
This delicious Baked Peanut Butter Oatmeal is such a great way to begin the day.
It has a moist, slightly chewy texture; it’s almost like eating cake for breakfast – but healthy!
It is important not to overcook the oats, or they will become dry. Bake until it feels just set in the centre and is pulling away slightly from the edges. However, if you prefer more moisture, you can add some extra milk or yoghurt when serving.
Yes, you can. Prepare the recipe as per the instructions – except for adding the baking powder – cover the bowl of oat mixture with clingfilm and place in the fridge for 8 hours. Add the baking powder and stir well before putting the mixture in your greased baking dish. The texture of the oats will be a little softer, but delicious all the same.
Store the Baked Peanut Butter Oatmeal in the fridge in an airtight container for up to 4 days. Reheat them as described below.
Yes, when cool, cut them into 6 bars. If storing in layers, place them in an airtight container with a sheet of non-stick baking paper between them so they do not stick together. If you want to remove individual bars, you could wrap each one in cling wrap and then in foil or an airtight container to prevent freezer burn. Store for up to 3 months. Be sure to label and date them as frozen items can be difficult to identify. Take them out of the freezer the night before you want them and put them in the fridge to thaw. Reheat as below.
Put the Baked Oatmeal breakfast bars on a baking tray or ovenproof plate, cover loosely with a sheet of baking paper and then foil. You can cover directly with foil if you wish, but I use the baking paper to prevent the aluminium foil from touching the food. Place them into a preheated 180 degrees C (355 F) oven and heat for 15 – 20 minutes or until warmed through. Remove the foil for about the last 5 minutes.
There are different rules regarding this, depending on where you live in the world. For Australian residents, Coeliac Australia provides a great resource on this topic. Always be sure to read the labels and consult with a health professional if you are unsure.
Variations and substitutions:
Chocolate chips – would be a great addition. You could also melt some dark chocolate and drizzle when serving.
Cinnamon – a little cinnamon is also delicious.
Milk – You can use dairy if you don’t want the oats to be vegan.
Banana – slices of banana are delicious with the warm oatmeal.
Serving suggestions:
Enjoy the Baked Peanut Butter Oatmeal as it is, or add toppings to suit your taste.
For this recipe, I like to use a topping of peanut butter yoghurt, which I make by whisking Greek yoghurt, peanut butter and maple syrup together. You can also use coconut yoghurt to keep the oats vegan.
You could also try:
- Slices of banana.
- Fresh berries or other fruit of your choice.
- Some roasted peanuts for great texture.
This Baked Peanut Butter Oatmeal is so easy to make, nourishing and perfect for meal prep. For easy breakfasts, keep some in the fridge or store some in the freezer. This is a breakfast for the whole family to enjoy.
