I haven’t made too many protein bars recently, but I played with some of my old ideas and managed to come up with this recipe that incorporates two of my very favorite ingredients, peanut butter and oatmeal. Anyone who has met me knows how much I like the stuff, and that most of my breakfasts include one or both of these ingredients.

What ingredients do you need to make these no-bake peanut butter oatmeal protein bars?

These healthy and delicious protein bars only contain 7 clean ingredients:

The maple syrup can be substituted for honey if you don’t want to make the bars vegan, and you can also customise these bars to make them your own, by adding chocolate chips, for example.

The golden flax seeds and chia seeds are excellent sources of fibre, and the peanut butter is the healthy fat that brings all the ingredients together.

How long do these protein bars keep in the fridge?

You can store these protein bars in the fridge for up to 14 days in an airtight container.

They are a good choice if you are into meal prep, as you can make a double batch and enjoy them either for breakfast or as a pre- or post-workout snack.

These no-bake peanut butter oatmeal protein bars taste more like dessert, but they still pack a healthy punch.

Prep Time 10 minutes
Total Time 10 minutes


  • 150 g rolled oats
  • 175 g smooth peanut butter
  • 150 g whey protein powder
  • 3 tbsp linseed (golden flax seeds)
  • 2 tbsp chia seeds
  • 50 g coconut oil
  • 90 g maple syrup


  1. Line up a 20 x 20 cm (8 x 8 inch) baking tin with parchment paper.
  2. Add the rolled oats, protein powder, linseed and chia seeds to a large bowl.
  3. In a separate, microwave-safe bowl, add the peanut butter, maple syrup, and coconut oil. Microwave for 20-25 seconds and mix until everything is smooth and combined.
  4. Add the mixture to the dry ingredients and mix until you get a very thick dough. The dough should be slightly crumbly, but if you feel it's too dry to work with, add another 10-15 grams of liquified coconut oil.
  5. Press the mixture into the lined tin, making sure you get it into the corners. Refrigerate for 1 hour.
  6. Cut the protein bars into 10 pieces (or 20 small squares if you prefer) and store in an airtight container for up to two weeks.
