Chewy Choc Chip Oat Protein Bars

By Lilian Dikmans


These gluten-free Chewy Choc Chip Oat Protein Bars are no bake, studded with chocolate chips and super easy to make. You can swap out the chocolate chips for your favourite chocolate bar, chopped into chunks. Adding some nuts into the mix is also delicious!

Since this is a no bake recipe, you can set the bars in any container you like. I used a 10 x 20cm loaf tin here, which gives thinner bars. You could press the mixture into a smaller tupperware container if you want to get thicker bars.

After chilling the mixture in its container to firm up, I cut the slab into 6 bars. But you can cut them as large or small as you want. If you want to make the mixture into protein balls, you can roll the mixture into balls instead of pressing it into a container.

Feel free to change up the chocolate chips. I like to use dark chocolate chips around 60-70% cocoa. But if you want to reduce the sugar content, you could chop up some 85% cocoa chocolate or a sugar-free chocolate bar instead.

Ingredients for Chewy Choc Chip Oat Protein Bars

Rolled oats: I use old fashioned rolled oats, which we process into a flour before adding to the mixture. Quick oats would also work if that’s all you have. Oats naturally don’t contain gluten, but they are often processed on the same equipment as wheat. If you’re strictly gluten-free, you can buy gluten-free oats.

Whey protein isolate: I use unflavoured whey protein isolate to boost the bars with protein, then sweeten the bars with the maple syrup. However, if you want to use a flavoured whey protein that contains sweetener, you could reduce the maple syrup and increase the milk slightly to replace the lost liquid.

The bars have a soft, chewy texture

Coconut flour: Combined with the oats, the coconut flour gives the bars a chewy texture. It also gives the bars structure and helps to hold them together.

Cashew butter: Stops the bars from drying out and provides some healthy fats. You could use another nut butter, like almond butter or peanut butter, if you prefer.

Maple syrup: Used to sweeten the bars, since I use unflavoured protein powder. You could also use honey or rice malt syrup. If you use a flavoured protein powder that is sweetened, you could reduce the maple syrup as mentioned above.

Rolled oats, dark chocolate chips, maple syrup, whey protein isolate, sea salt, cashew butter, unsweetened almond milk and coconut flour

Unsweetened almond milk: Just a small amount is used to bring the mixture to a dough consistency. You can use any milk you like, or water if you don’t have any milk.

Dark chocolate chips: Feel free to use any chocolate chips you like. Or chop up your favourite chocolate bar and use that instead.

Sea salt: Enhances the flavour of the bars. You can leave it out, but I highly recommend including it.

I haven’t tested the recipe with a plant-based protein powder, but I image it would work since there’s not a large amount of protein powder used. You may just need to add a little extra milk to get the mixture to form a dough, since plant-based protein powders are usually drier than whey.

Chewy Choc Chip Oat Protein Bars Recipe

6 bars

Prep time
10 mins

Cook time
20 mins chilling


  • 1 cup (90g) rolled oats
  • 1/4 cup (62g) cashew butter
  • 1/4 cup (60ml/78g) maple syrup
  • 1/8 teaspoon sea salt
  • 1/4 cup (25g) unflavoured whey protein isolate
  • 1/4 cup (25g) coconut flour
  • 4 teaspoons (20ml/20g) unsweetened almond milk, or more as needed
  • 1/4 cup (40g) dark chocolate chips


  • 1
    Line a 10 x 20cm loaf tin (or a similar sized container) with baking paper or cling film. Process the oats in a food processor or blender to turn them into a flour.
  • 2
    Place the cashew butter, maple syrup and sea salt into a large mixing bowl and stir well to combine. Add the oat flour, whey protein powder and coconut flour and mix well. Add the almond milk one teaspoon at a time and continue to mix until you get a dough. If it’s too dry add another teaspoon of milk. If it gets too sticky, add a little extra coconut flour.
  • 3
    Mix about two thirds of the chocolate chips into the dough. I find it easiest to work the chips into the dough with my hands.
  • 4
    Firmly press the dough into the lined tin, sprinkle over the remaining chocolate chips and press them into the surface. Chill in the freezer for about 20 minutes until firm before slicing into bars.
  • 5
    Store in an airtight container in the fridge or freezer.


The bars are best eaten within 1-3 days. Any extra bars that you won’t eat in this time can be frozen, then defrosted in the fridge as needed.

You can also make the mixture into protein balls if you prefer. Just shape the dough into balls instead of pressing into a tin.
