These healthy, no-bake peanut butter oatmeal protein bars are packed with protein and fibre, and you'll keep you full while satisfying your cravings for something sweet.
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:
- 150 g rolled oats
- 175 g smooth peanut butter
- 150 g vegan protein powder
- 3 tablespoon linseed (golden flax seeds)
- 2 tablespoon chia seeds
- 50 g coconut oil
- 90 g maple syrup
The maple syrup can be substituted for honey if you don't want to make the bars vegan, and you can also customize these bars to make them your own by adding chocolate chips, for example.
Golden flax seeds and chia seeds are excellent sources of fibre, and peanut butter is the healthy fat that combines all the ingredients.
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.
